In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three-and nine-month periods ended February 28, 2021 and February 29, 2020.

We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS New Pronouncements Adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses,” which requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Additionally, the standard amends the current available-for-sale securities other-than-temporary impairment model for debt securities. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods therein. The adoption of this new guidance, effective June 1, 2020, using the modified retrospective transition method, did not result in a cumulative-effect adjustment to the opening balance of retained earnings at June 1, 2020 and did not have a material impact on the Company's Consolidated Financial Statements. Refer to Note 14, “Revenue” for additional information. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. The adoption of this new guidance, effective June 1, 2020, did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this new guidance, effective June 1, 2020, did not have a material impact on our Consolidated Financial Statements or disclosures. New Pronouncements Issued In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20), Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with employers that sponsor defined benefit or other postretirement plans. This guidance is effective for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities and the amendments in this update are required to be applied on a retrospective basis to all periods presented. We are currently evaluating the expected impact of this new pronouncement on our annual Co nsolidated Financial Statements , and disclosures, but do not expect our adoption of this guidance to have a material impact . In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. We are currently reviewing the provisions of this new pronouncement, but do not expect our adoption of this guidance to have a material impact on our Consolidated Financial Statements.

Restructuring And Related Activities [Abstract]
Restructuring	NOTE 3 — RESTRUCTURING We record restructuring charges associated with management-approved restructuring plans to either reorganize one or more of our business segments, or to remove duplicative headcount and infrastructure associated with our businesses. Restructuring charges can include severance costs to eliminate a specified number of employees, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs and other costs. Restructuring charges are recorded based upon planned employee termination dates and site closure and consolidation plans. The timing of associated cash payments is dependent upon the type of restructuring charge and can extend over a multi-year period. We record the short-term portion of our restructuring liability in Other Accrued Liabilities and the long-term portion, if any, in Other Long-Term Liabilities in our Consolidated Balance Sheets. MAP to Growth Between May and August 2018, we approved and implemented the initial phases of a multi-year restructuring plan, which was originally referred to as the 2020 Margin Acceleration Plan (“2020 MAP to Growth”). The initial phases of our 2020 MAP to Growth affected all of our reportable segments, as well as our corporate/nonoperating segment, and focused on margin improvement by simplifying business processes; reducing inventory categories and rationalizing SKUs; eliminating underperforming businesses; reducing headcount and working capital; and improving operating efficiency. The activities included in the initial phases of the restructuring activities have been substantially completed. The disruption caused by the outbreak of Covid-19 (“Covid”) delayed the finalization of our 2020 MAP to Growth past the original target completion date of December 31, 2020. In recognition of the fact our restructuring plan extends past calendar year 2020, we will now refer to it simply as “MAP to Growth.” As previously disclosed, we expect to utilize the remainder of fiscal year 2021 to achieve the goals originally set forth in our MAP to Growth. Certain of these projects may not be finalized until fiscal year 2022 and we would expect to continue to recognize restructuring expense throughout fiscal year 2022, as projects related to our MAP to Growth are executed and completed. As such, the final implementation and total expected costs are subject to change. Our execution of the MAP to Growth will continue to drive the de-layering and simplification of management and businesses associated with group realignment. We have implemented four center-led functional areas including manufacturing and operations; procurement and supply chain; information technology; and accounting and finance. Our MAP to Growth optimizes our manufacturing facilities and will ultimately provide more efficient plant and distribution facilities. Through the balance sheet date, in association with our MAP to Growth, we have completed, or are in the process of completing, the planned closure of 26 plants and 27 warehouses. We also expect to incur additional severance and benefit costs as part of our planned closure of these facilities. Throughout the remainder of our MAP to Growth, we will continue to assess and find areas of improvement and cost savings. As such, the final implementation and total expected costs are subject to change. In addition to the announced plan, we have continued to broaden the scope of our MAP to Growth, specifically in consolidation of the general and administrative areas, potential outsourcing, as well as additional future plant closures and consolidations; the estimated costs of which have not yet been finalized. The current total expected costs associated with this plan are outlined in the table below and increased by approximately $0.8 million compared to our previous estimate, primarily attributable to increases in expected severance and benefit charges of $1.3 million and expected facility closure and other related costs of $0.2 million. These increases were partially offset by a decrease in expected other restructuring costs of $0.7 million.

During the three months ended February 29, 2020, we incurred inventory-related charges of approximately $0.2 million at our Consumer segment and $0.1 million of inventory-related charges at each of our CPG, PCG and SPG segments, respectively. During the nine months ended February 28, 2021, we incurred inventory-related charges of approximately $1.0 million at our Consumer segment. During the nine months ended February 29, 2020, we incurred approximately $7.4 million, $3.2 million, $0.3 million and $0.1 million of inventory-related charges at our Consumer, PCG, CPG, and SPG segments, respectively. All of the aforementioned inventory-related charges are recorded in cost of sales in our Consolidated Statements of Income. These inventory charges were the result of the exit of a business or product line and SKU rationalization initiatives in connection with our overall plan of restructuring.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 4 — FAIR VALUE MEASUREMENTS Financial instruments recorded in the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt. An allowance for expected uncollectible trade receivable amounts is established using a combination of specifically identified accounts to be reserved, and a reserve covering trends in collectibility. These estimates are based on an analysis of trends in collectibility and past experience, but are primarily made up of individual account balances identified as doubtful based on specific facts and conditions. Receivable losses are charged against the allowance when we conclude on uncollectibility. All derivative instruments are recognized in our Consolidated Balance Sheets and measured at fair value. Changes in the fair values of derivative instruments that do not qualify as hedges and/or any ineffective portion of hedges are recognized as a gain or (loss) in our Consolidated Statements of Income in the current period. Changes in the fair value of derivative instruments used effectively as cash flow hedges are recognized in other comprehensive income (loss), along with the change in the value of the hedged item. We do not hold or issue derivative instruments for speculative purposes. The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows: Level 1 Inputs — Quoted prices for identical instruments in active markets. Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs — Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. In addition, with respect to our derivative assets and liabilities measured at fair value, refer to Note 5, “Derivatives and Hedging” for discussion of their classification within the fair value hierarchy. (In thousands) Quoted in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value at February 28, 2021 Available-for-sale debt securities: U.S. Treasury and other government $ - $ 25,447 $ - $ 25,447 Corporate bonds - 181 - 181 Total available-for-sale debt securities - 25,628 - 25,628 Marketable equity securities: Stocks - foreign 536 - - 536 Stocks - domestic 6,240 - - 6,240 Mutual funds - foreign - 42,445 - 42,445 Mutual funds - domestic - 77,919 - 77,919 Total marketable equity securities 6,776 120,364 - 127,140 Contingent consideration - - (15,258 ) (15,258 ) Total $ 6,776 $ 145,992 $ (15,258 ) $ 137,510 (In thousands) Quoted in Active Markets for Identical (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value at May 31, 2020 Available-for-sale debt securities: U.S. Treasury and other government $ - $ 26,736 $ - $ 26,736 Corporate bonds - 186 - 186 Total available-for-sale debt securities - 26,922 - 26,922 Marketable equity securities: Stocks - domestic 3,870 - - 3,870 Mutual funds - foreign - 28,815 - 28,815 Mutual funds - domestic - 63,536 - 63,536 Total marketable equity securities 3,870 92,351 - 96,221 Contingent consideration - - (15,682 ) (15,682 ) Total $ 3,870 $ 119,273 $ (15,682 ) $ 107,461 Our investments in available-for-sale debt securities and marketable equity securities are valued using a market approach. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors, including the type of instrument, whether the instrument is actively traded and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment. The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled, and applied a discount rate that appropriately captures a market participant's view of the risk associated with the obligation, which are considered to be Level 3 inputs. During the first nine months of fiscal 2021, we paid approximately $2.8 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the current period, and recorded an increase in the accrual for approximately $1.8 million related to fair value adjustments. During the first nine months of fiscal 2020, we paid approximately $6.1 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the first nine months of last year. In the Consolidated Statements of Cash Flows, payments of acquisition-related contingent consideration for the amount recognized at fair value as of the acquisition date are reported in cash flows from financing activities, while payments of contingent consideration in excess of fair value are reported in cash flows from operating activities. The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At February 28, 2021 and May 31, 2020, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of February 28, 2021 and May 31, 2020 are as follows: At February 28, 2021 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 249,214 $ 249,214 Marketable equity securities 127,140 127,140 Available-for-sale debt securities 25,628 25,628 Long-term debt, including current portion 2,311,510 2,507,299 At May 31, 2020 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 233,416 $ 233,416 Marketable equity securities 87,111 87,111 Available-for-sale debt securities 26,922 26,922 Long-term debt, including current portion 2,539,180 2,618,719

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	NOTE 5 — DERIVATIVES AND HEDGING Derivative Instruments and Hedging Activities We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures, from time to time, we enter into various derivative transactions. We use various types of derivative instruments including forward contracts and swaps. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess, both at inception and at least quarterly thereafter, whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures. Derivatives Designated as Hedges In October 2017, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a fair value hedge and two cross currency swaps, in which we paid variable rate interest in Euros and received fixed rate interest in U.S. Dollars with a combined notional amount of approximately €85.25 million ($100 million U.S. Dollar equivalent), and which had a maturity date of November 2022. This effectively converted a portion of our U.S. Dollar denominated fixed-rate debt to Euro denominated variable rate debt. The fair value hedge was recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge were recognized in interest expense in our Consolidated Statements of Income. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. In February 2020, the fair value hedge and two cross currency swaps agreements were terminated, and we received cash in the amount of $9.3 million, representing the fair value of the swap and interest accrued through the date of termination. Accordingly, hedge accounting was discontinued and a hedge accounting adjustment to our Senior Notes of $1.5 million was recorded and is being amortized to interest expense in the Consolidated Statements of Income through the termination of the 3.450% Notes in November 2022. Changes in the fair value of the cross currency swaps due to spot foreign exchange rates are recorded as cumulative translation adjustment within AOCI and will remain in AOCI until either the sale or substantially complete liquidation of the hedged subsidiaries. Separately, in February 2020, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a cash flow hedge and two cross currency swaps, in which we will pay fixed rate interest in Euros and receive variable rate interest in U.S. Dollars with a combined notional amount of approximately €277.73 million ($300 million U.S. Dollar equivalent), and which have a maturity date of February 2023. This effectively converts our U.S. Dollar denominated variable rate debt to Euro denominated fixed rate debt. The cash flow hedge is recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge will be recognized in AOCI when the hedged items affect earnings. Amounts recognized in AOCI will be recognized in earnings in interest expense when the hedged interest payment is accrued. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. The changes in fair value of the derivative instruments that are designated and qualify as hedges of net investments in foreign operations are recognized in AOCI to offset the changes in the values of the net investments being hedged. In addition, in February 2020, as a means of mitigating the variability of the functional-currency-equivalent cash flows associated with the U.S. Dollar denominated term loan facility (referred to as Foreign Borrower’s Term Loan), we executed a cash flow hedge, in which we will pay fixed rate interest in Euros and receive variable rate interest in U.S. Dollars with a notional amount of approximately €92.52 million ($100 million U.S. Dollar equivalent), and which have a maturity date of February 2023. This effectively converts our U.S. Dollar denominated variable rate debt to Euro denominated fixed rate debt. The cash flow hedge is recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge will be recognized in AOCI when the hedged items affect earnings. Amounts recorded in AOCI will be recognized in earnings in interest expense when the hedged interest payment is accrued. In addition, since this currency swap is a hedge of variability of the functional currency equivalent cash flows of a recognized liability to be remeasured at spot exchange rates under ASC 830, an amount that will offset the gain or loss arising from the remeasurement of the hedged liability will be reclassified each period from AOCI to earnings as foreign exchange gain/(loss), which is a component of SG&A expenses.

The contract has not been designated as a hedge; therefore, the changes in fair value of the derivative are recognized in earnings as a component of SG&A expenses. Amounts recognized in earnings did not have a material impact on our Consolidated Financial Statements for any period presented.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8 — INCOME TAXES The effective income tax rate of 31.1% for the three months ended February 28, 2021 compares to the effective income tax rate of 25.9% for the three months ended February 29, 2020. The effective income tax rate for the three months ended February 28, 2021 and February 29, 2020 reflect variances from the 21% statutory rate due primarily to the unfavorable impact of state and local income taxes, non-deductible business expenses, the net tax on foreign subsidiary income resulting from the global intangible low-taxed income provisions and an increase in valuation allowances related to foreign net operating losses. Additionally, during the three-month period ended February 28, 2021, we recorded a $5.3 million discrete charge for an increase to our deferred income tax liability for withholding taxes on additional unremitted foreign earnings not considered permanently reinvested. The effective income tax rate of 25.2% for the nine months ended February 28, 2021 compares to the effective income tax rate of 24.9% for the nine months ended February 29, 2020. The effective income tax rate for the nine months ended February 28, 2021 and February 29, 2020 reflect variances from the 21% statutory rate due primarily to the unfavorable impact of state and local income taxes, non-deductible business expenses, the net tax on foreign subsidiary income resulting from the global intangible low-taxed income provisions and an increase in valuation allowances related to foreign net operating losses, partially offset by tax benefits associated with equity compensation. The nine- month period ended February 28, 2021 also reflects the above noted $5.3 million charge related to foreign earnings not permanently reinvested. Our deferred tax liability for unremitted foreign earnings was $17.7 million as of February 28, 2021, which represents our estimate of the foreign tax cost associated with the deemed remittance of $620.7 million of foreign earnings that are not considered to be permanently reinvested. We have not provided for foreign withholding or income taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of February 28, 2021. Accordingly, no provision has been made for foreign withholding or income taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were remitted to us as dividends.

Equity [Abstract]
Stock Repurchase Program	NOTE 10 — STOCK REPURCHASE PROGRAM On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion for general corporate purposes. As announced on November 28, 2018, our goal was to return $1.0 billion in capital to stockholders by May 31, 2021 through share repurchases. On April 16, 2019, after taking into account share repurchases under our existing stock repurchase program to date, our Board of Directors authorized the repurchase of the remaining $600.0 million in value of RPM International Inc. common stock by May 31, 2021. As a result, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. As previously announced, given macroeconomic uncertainty resulting from the Covid pandemic, we had suspended stock repurchases under the program. During a meeting in January 2021, our Board of Directors authorized the resumption of the stock repurchases under the stock repurchase program. At the time of resuming the program, $469.7 million of shares of common stock remained available for repurchase. The Board of Directors also extended the stock repurchase program beyond its original May 31, 2021 expiration date until such time that the remaining $469.7 million of shares of capital has been returned to our stockholders. During the three and nine months ended February 28, 2021, we repurchased 290,174 shares of our common stock at a cost of approximately $24.6 million, or an average of $84.87 per share. During the three months ended February 29, 2020, we did not repurchase any shares of our common stock under this program. During the nine months ended February 29, 2020, we repurchased 1,655,616 shares of our common stock at a cost of approximately $100.0 million, or an average cost of $60.40 per share, under this program. See Note 17, “Subsequent Events” for an update on additional repurchases occurring subsequent to our February 28, 2021 balance sheet date.

We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, and these fluctuations may have a material impact on our consolidated financial results in the future. We previously disclosed in our financial statements for the fiscal year ended May 31, 2020 that we expected to contribute approximately $8,000 to our retirement plans in the U.S. and approximately $6.7 million to plans outside the U.S. during the current fiscal year. As noted in prior quarters, throughout the year, we have evaluated whether to make additional contributions. As a result, we contributed $62.1 million to the pension plans in the U.S. during the current quarter and have planned an additional contribution of $0.2 million before the end of our fiscal year, which will result in total expected U.S. contributions of $62.3 million.

Contingencies and Accrued Losse

Contingencies and Accrued Losses	9 Months Ended
	Feb. 28, 2021
Commitments And Contingencies Disclosure [Abstract]
Contingencies and Accrued Losses	NOTE 13 — CONTINGENCIES AND ACCRUED LOSSES Product Liability Matters We provide, through our wholly owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses as well as other uninsured claims. Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times. To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position. Warranty Matters We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at February 28, 2021, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Based upon the nature of the expense, product warranty expense is recorded as a component of cost of sales or within SG&A. Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next. While our warranty liabilities represent our best estimates of our expected losses at any given time, from time-to-time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors. The following table includes the changes in our accrued warranty balances: Three Months Ended Nine Months Ended February 28, February 29, February 28, February 29, (In thousands) 2021 2020 2021 2020 Beginning Balance $ 12,050 $ 10,555 $ 11,106 $ 10,414 Deductions (1) (4,745 ) (4,622 ) (18,327 ) (16,002 ) Provision charged to expense 5,473 4,804 19,999 16,325 Ending Balance $ 12,778 $ 10,737 $ 12,778 $ 10,737 (1) Primarily claims paid during the year. Environmental Matters Like other companies participating in similar lines of business, some of our subsidiaries are involved in environmental matters. It is our policy to accrue remediation costs when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when the Company has committed to an appropriate plan of action. The Company also takes into consideration the estimated period of time over which payments may be required. The liabilities are reviewed periodically and, as investigation and remediation activities continue, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not offset by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites. Other Contingencies – “SEC Investigation and Enforcement Action” We were notified by the SEC on June 24, 2014, that we were the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed U.S. Department of Justice (the “DOJ”) and the U.S. General Services Administration (the “GSA”) Office of Inspector General investigation into compliance issues relating to Tremco Roofing Division’s GSA contracts. As previously disclosed, our Audit Committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigation, and determined that it was appropriate to restate our financial results for the first, second and third quarters of fiscal 2013. The restatement shifted accrual amounts among the three quarters, which had the effect of reducing net income by $7.2 million and $10.8 million for the quarterly periods ended August 31, 2012, and November 30, 2012, respectively, and increasing net income for the quarterly period ended February 28, 2013 by $18.0 million. These restatements had no impact on our audited financial statements for the fiscal years ended May 31, 2013 or 2014. In connection with the foregoing, on September 9, 2016, the SEC filed an enforcement action against us and our General Counsel. The complaint sought disgorgement of gains that may have resulted from the conduct alleged in the complaint, and payment of unspecified monetary penalties from us and our General Counsel pursuant to Section 20(d) of the Securities Act and Section 21(d)(3) of the Exchange Act. Further, the complaint sought to permanently enjoin us from violations of Sections 17(a)(2) and (a)(3) of the Securities Act, Sections 13(a), 13(b)(2)(A) and 13(b)(2)(B) of the Exchange Act, and Exchange Act Rules 12b-20, 13a-1, 13a-11 and 13a-13, and to permanently enjoin our General Counsel from violations of Sections 17(a)(2) and (a)(3) of the Securities Act and Exchange Act Rules 13b2-1 and 13b2-2(a). On December 22, 2020, the Court entered its Final Judgment (the “Final Judgment”) resolving this matter with the SEC. In consenting to the terms of the Final Judgment, we and our General Counsel neither admitted nor denied the SEC’s allegations. We agreed to pay a civil monetary penalty of $2.0 million under Section 21(d)(3) of the Exchange Act, and we are permanently enjoined from violations of Section 13(a), 13(b)(2)(a) and 13(b)(2)(b) of the Exchange Act and Exchange Act Rules 12b-20, 13a-1, 13a-11 and 13a-13. The settlement amount was accrued for in our consolidated financial statements as of November 30, 2020. Our General Counsel agreed to pay a civil monetary penalty of $22,500 under Section 21(d)(3) of the Exchange Act, and he is permanently enjoined from violations of Exchange Act Rule 13b2-1. Both the Company and our General Counsel have paid their respective civil monetary penalties during the fiscal quarter ended February 28, 2021. For both the Company and our General Counsel, the Final Judgment resolved all claims asserted by the SEC in the proceeding and included relief only with respect to certain books and records provisions of the securities laws, none of which require proof of intentional or willful misconduct. Also, in connection with the foregoing, on April 28, 2017, a stockholder derivative action was filed in the United States District Court, Northern District of Ohio, Eastern Division, against certain of our current and former directors and officers. On February 2, 2018, the Court granted our request for a stay and stayed the derivative action pending the completion of the SEC enforcement action. The stay may be revisited by the Court now that the SEC enforcement action has been resolved. We do not believe a material loss in this matter is reasonably possible or probable.

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	NOTE 14 – REVENUE We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings, roofing systems, sealants and adhesives. We disaggregate revenues from the sales of our products and services based upon geographical location by each of our reportable segments, which are aligned by similar economic factors, trends and customers, which best depict the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. See Note 15, “Segment Information,” for further details regarding our disaggregated revenues as well as a description of each of the unique revenue streams related to each of our four reportable segments. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The majority of our revenue is recognized at a point in time. However, we also record revenues generated under construction contracts, mainly in connection with the installation of specialized roofing and flooring systems and related services. For certain polymer flooring installation projects, we account for our revenue using the output method, as we consider square footage of completed flooring to be the best measure of progress toward the complete satisfaction of the performance obligation. In contrast, for certain of our roofing installation projects, we account for our revenue using the input method, as that method was the best measure of performance as it considers costs incurred in relation to total expected project costs, which essentially represents the transfer of control for roofing systems to the customer. In general, for our construction contracts, we record contract revenues and related costs as our contracts progress on an over-time model. We have elected to apply the practical expedient to recognize revenue net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type, although our customers’ payment terms generally include a requirement to pay within 30 to 60 days of fulfilling our performance obligations. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. We have elected to apply the practical expedient to treat all shipping and handling costs as fulfillment costs, as a significant portion of these costs are incurred prior to control transfer. Significant Judgments Our contracts with customers may include promises to transfer multiple products and/or services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For example, judgment is required to determine whether products sold in connection with the sale of installation services are considered distinct and accounted for separately, or not distinct and accounted for together with installation services and recognized over time. We provide customer rebate programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration and recognized as a reduction of net sales. Up-front consideration provided to customers is capitalized as a component of other assets and amortized over the estimated life of the contractual arrangement. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. In general, this determination is made based upon known customer program and incentive offerings at the time of sale, and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. Certain of our contracts include contingent consideration that is receivable only upon the final inspection and acceptance of a project. We include estimates of such variable consideration in our transaction price. Based on historical experience, we consider the probability-based expected value method appropriate to estimate the amount of such variable consideration. Our products are generally sold with a right of return and we may provide other credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. We record a right of return liability to accrue for expected customer returns. Historical actual returns are used to estimate future returns as a percentage of current sales. Obligations for returns and refunds were not material individually or in the aggregate. We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term. Warranty liabilities for our assurance type warranties are discussed further in Note 13, “Contingencies and Accrued Losses.” Contract Balances Timing of revenue recognition may differ from the timing of invoicing customers. Our contract assets are recorded for products and services that have been provided to our customer but have not yet been billed, and are included in prepaid expenses and other current assets in our consolidated balance sheets. Our short-term contract liabilities consist of advance payments, or deferred revenue, and are included in other accrued liabilities in our consolidated balance sheets. Trade accounts receivable, net of allowances, and net contract assets (liabilities) consisted of the following: (In thousands, except percentages) February 28, 2021 November 30, 2020 $ Change % Change Trade accounts receivable, less allowances $ 998,783 $ 1,081,841 $ (83,058 ) -7.7 % Contract assets $ 22,993 $ 27,154 $ (4,161 ) -15.3 % Contract liabilities - short-term (31,918 ) (28,310 ) (3,608 ) 12.7 % Net Contract (Liabilities) $ (8,925 ) $ (1,156 ) $ (7,769 ) 672.1 % (In thousands, except percentages) February 28, 2021 May 31, 2020 $ Change % Change Trade accounts receivable, less allowances $ 998,783 $ 1,137,957 $ (139,174 ) -12.2 % Contract assets $ 22,993 $ 25,249 $ (2,256 ) -8.9 % Contract liabilities - short-term (31,918 ) (25,288 ) (6,630 ) 26.2 % Net Contract (Liabilities) $ (8,925 ) $ (39 ) $ (8,886 ) The $7.8 million increase in our net contract (liabilities) from November 30, 2020 to February 28, 2021 resulted primarily due to the timing and volume of construction jobs in progress at February 28, 2021 versus November 30, 2020. During the third quarter of fiscal 2021, net sales at our U.S. based general contracting and roofing services business decreased by $26.6 million as compared to the second quarter of fiscal 2021. Due to the seasonal nature of our business, unbilled revenue is typically higher in the fall months (at the conclusion of RPM’s second fiscal quarter) when favorable weather generally allows our installers to maximize productivity, and is lower throughout the winter months (at the conclusion of RPM’s third fiscal quarter) when inconsistent weather adversely impacts productivity. The $8.9 million increase in our net contract (liabilities) from May 31, 2020 to February 28, 2021 resulted primarily due to the timing and volume of construction jobs in progress at February 28, 2021 versus May 31, 2020. During the third quarter of fiscal 2021, net sales at our U.S. based general contracting and roofing services business decreased by $41.9 million as compared to the fourth quarter of fiscal 2020. Due to the seasonal nature of our business, unbilled revenue is typically higher in the spring months (at the conclusion of RPM’s fourth fiscal quarter) when favorable weather generally allows our installers to maximize productivity, and is lower throughout the winter months (at the conclusion of RPM’s third fiscal quarter) when inconsistent weather adversely impacts productivity. We also record long-term deferred revenue, which amounted to $67.1 million, $66.9 million and $66.0 million as of February 28, 2021, November 30, 2020 and May 31, 2020, respectively. The long-term portion of deferred revenue is related to warranty contracts and is included in other long-term liabilities in our consolidated balance sheets. We have elected to adopt the practical expedient to not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the reporting period for performance obligations that are part of a contract with an original expected duration of one year or less. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. As our contract terms are primarily one year or less in duration, we have elected to apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include our internal sales force compensation program and certain incentive programs as we have determined annual compensation is commensurate with annual sales activities. Allowance for Credit Losses Our primary allowance for credit losses is the allowance for doubtful accounts. The allowance for doubtful accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The allowance was based on assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowances for doubtful collection of accounts are included in selling, general and administrative expenses. The following tables summarize the activity for the allowance for credit losses for the three and nine months ended February 28, 2021: (In thousands) Balance at November 30, 2020 $ 53,542 Bad debt provision 3,800 Uncollectible accounts written off, net of recoveries (5,661 ) Translation adjustments 522 Balance at February 28, 2021 $ 52,203 (In thousands) Balance at June 1, 2020 $ 55,847 Bad debt provision 4,968 Uncollectible accounts written off, net of recoveries (11,008 ) Translation adjustments 2,396 Balance at February 28, 2021 $ 52,203

Segment Reporting [Abstract]
Segment Information	NOTE 15 — SEGMENT INFORMATION We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings and roofing systems, flooring solutions, sealants, cleaners and adhesives. We manage our portfolio by organizing our businesses and product lines into four reportable segments as outlined below, which also represent our operating segments. Within each operating segment, we manage product lines and businesses which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our four operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These four operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses. We evaluate the profit performance of our segments primarily based on income before income taxes, but also look to earnings (loss) before interest and taxes (“EBIT”) as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations. Our CPG reportable segment products are sold throughout North America and also account for the majority of our international sales. Our construction product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. Products and services within this reportable segment include construction sealants and adhesives, coatings and chemicals, roofing systems, concrete admixture and repair products, building envelope solutions, insulated cladding, flooring systems, and weatherproofing solutions. Our PCG reportable segment products are sold throughout North America, as well as internationally, and are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. Products and services within this reportable segment include high-performance flooring solutions, corrosion control and fireproofing coatings, infrastructure repair systems, fiberglass reinforced plastic gratings and drainage systems. Our Consumer reportable segment manufactures and markets professional use and do-it-yourself (“DIY”) products for a variety of mainly consumer applications, including home improvement and personal leisure activities. Our Consumer segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe and other parts of the world. Our Consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops and through distributors. The Consumer reportable segment offers products that include specialty, hobby and professional paints; caulks; adhesives; cleaners; sandpaper and other abrasives; silicone sealants and wood stains. Our SPG reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our specialty product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The SPG reportable segment offers products that include industrial cleaners, restoration services equipment, colorants, nail enamels, exterior finishes, edible coatings and specialty glazes for pharmaceutical and food industries, and other specialty original equipment manufacturer (“OEM”) coatings. In addition to our four reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes and identifiable assets. We reflect income from our joint ventures on the equity method, and receive royalties from our licensees. The following tables present a disaggregation of revenues by geography, and reflect the results of our reportable segments consistent with our management philosophy, by representing the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of businesses.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill	NOTE 16 — GOODWILL We account for goodwill and other intangible assets in accordance with the provisions of ASC 350 and account for business combinations using the acquisition method of accounting and, accordingly, the assets and liabilities of the entities acquired are recorded at their estimated fair values at the acquisition date. Goodwill represents the excess of the purchase price paid over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. We assess goodwill for impairment annually during the fourth quarter, or more frequently, if events and circumstances indicate impairment may have occurred. We test goodwill for impairment at the reporting unit level. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination as of the acquisition date. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill. We evaluate our reporting units when changes in our operating structure occur, and if necessary, reassign goodwill using a relative fair value allocation approach. The following table summarizes the changes in the carrying amount of goodwill, by reportable segment, for the periods presented: CPG PCG Consumer SPG (In thousands) Segment Segment Segment Segment Total Balance as of May 31, 2020 $ 405,354 $ 185,404 $ 496,218 $ 163,090 $ 1,250,066 Translation adjustments & other 21,396 265 4,075 2,732 28,468 Balance as of August 31, 2020 426,750 185,669 500,293 165,822 1,278,534 Acquisitions - - 20,126 - 20,126 Translation adjustments & other 1,238 458 (145 ) 566 2,117 Balance as of November 30, 2020 427,988 186,127 520,274 166,388 1,300,777 Translation adjustments & other 3,243 2,515 3,245 982 9,985 Balance as of February 28, 2021 $ 431,231 $ 188,642 $ 523,519 $ 167,370 $ 1,310,762

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS New Pronouncements Adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses,” which requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Additionally, the standard amends the current available-for-sale securities other-than-temporary impairment model for debt securities. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods therein. The adoption of this new guidance, effective June 1, 2020, using the modified retrospective transition method, did not result in a cumulative-effect adjustment to the opening balance of retained earnings at June 1, 2020 and did not have a material impact on the Company's Consolidated Financial Statements. Refer to Note 14, “Revenue” for additional information. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. The adoption of this new guidance, effective June 1, 2020, did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this new guidance, effective June 1, 2020, did not have a material impact on our Consolidated Financial Statements or disclosures. New Pronouncements Issued In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20), Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with employers that sponsor defined benefit or other postretirement plans. This guidance is effective for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities and the amendments in this update are required to be applied on a retrospective basis to all periods presented. We are currently evaluating the expected impact of this new pronouncement on our annual Co nsolidated Financial Statements , and disclosures, but do not expect our adoption of this guidance to have a material impact . In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. We are currently reviewing the provisions of this new pronouncement, but do not expect our adoption of this guidance to have a material impact on our Consolidated Financial Statements.
