Accounting Policies [Abstract]
ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES	ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES CSW Industrials, Inc. (“CSWI,” “we,” “our” or “us”) is a diversified industrial growth company with well-established, scalable platforms and domain expertise across two business segments: Industrial Products and Specialty Chemicals. Our broad portfolio of leading products provides performance optimizing and life safety solutions to our customers. Our products include mechanical products for heating, ventilation, air conditioning and refrigeration (“HVAC/R”), building products and high-performance specialty lubricants and sealants. Drawing on our innovative and proven technologies, we seek to deliver solutions primarily to our professional end-use customers that place a premium on superior performance and reliability. Our diverse product portfolio includes more than 100 highly respected industrial brands including No. 5®, KOPR-KOTE®, Kats Coatings®, Safe-T-Switch®, Air Sentry®, Deacon®, Leak Freeze® and Greco® . Our products are well-known in the specific industries we serve and have a reputation for high quality and reliability. Markets that we serve include HVAC/R, architecturally-specified building products, plumbing, energy, rail, mining and general industrial markets. In March 2020, the World Health Organization declared the outbreak of a novel coronavirus ("COVID-19") a pandemic. COVID-19 continues to spread throughout the world and has led certain countries or jurisdictions within them to restrict travel, social gatherings and certain types of business activity deemed to be "non-essential," which has created a recessionary environment in the U.S. and around the globe and has led to a decline in demand in some end markets, including several that we serve. Also, in March 2020, as a result of the weakened demand for crude oil resulting from the COVID-19 pandemic, and magnified by political tensions between several large crude oil-producing countries, there was a substantial decline in crude oil prices magnified by significant volatility that has continued to date. Both factors had a negative impact on our revenues in the three and six months ended September 30, 2020, as compared with the same periods in fiscal 2020, and are expected to negatively impact our results in the balance of fiscal year 2021. We expect our results of operations and financial condition to continue to be adversely impacted as compared with the prior year through the duration of the pandemic due to its effects on the economy and demand for our products and services. However, we cannot reasonably estimate the magnitude or length of the adverse impact due to continued uncertainty regarding (1) the duration and severity of the COVID-19 pandemic and (2) the extent of the potential short and long-term impact on our facilities and employees, customer demand and availability of materials through supply channels. Basis of Presentation The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2020 (“Quarterly Report”), include all revenues, costs, assets and liabilities directly attributable to CSWI and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSWI’s financial position as of September 30, 2020, and the results of operations for the three and six month periods ended September 30, 2020 and 2019. All adjustments are of a normal, recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSWI’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020 (the “Annual Report”). Accounting Policies We have consistently applied the accounting policies described in our Annual Report in preparing these condensed consolidated financial statements. We have not made any changes in significant accounting policies disclosed in the Annual Report, with the exception of the expected credit loss accounting policy described below as a result of adopting the new expected credit loss standard. Current Expected Credit Losses ("CECL") - We record an allowance for credit losses on trade receivables that, when deducted from the gross trade receivables balance, presents the net amount expected to be collected. We estimate the allowance based on an aging schedule and according to historical losses as determined from our billings and collections history. This may be adjusted after consideration of customer-specific factors such as financial difficulties, liquidity issues or insolvency, as well as both current and forecasted macroeconomic conditions as of the reporting date. We adjust the allowance and recognize credit losses in the income statement each period. Trade receivables are written off against the allowance in the period when the receivable is deemed to be uncollectible. Subsequent recoveries of amounts previously written off are reflected as a reduction to periodic credit losses in the income statement. Our allowance for expected credit losses for short-term receivables as of September 30, 2020 was $0.6 million, compared to $1.2 million as of March 31, 2020. The six months activity included $0.3 million for current period adjustments. Accounting Developments Pronouncements Implemented In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The ASU requires, among other things, the use of a new current expected credit loss model in order to determine an allowance for credit losses with respect to financial assets and instruments held. The CECL model requires that we estimate the lifetime of an expected credit loss for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. On April 1, 2020 we adopted the ASU on a prospective basis to determine our allowance for credit losses in accordance with the requirements of Topic 326, and we modified our accounting policy and processes to facilitate this approach. Our primary exposure to financial assets that are within the scope of CECL are trade receivables. Our adoption of ASU No. 2016-13 effective April 1, 2020 did not have a material impact on our condensed consolidated financial condition and results of operations. In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendments of the ASU modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosure requirements for assets and liabilities measured at fair value in the statement of financial position or disclosed in the notes to the financial statements. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for the new disclosures. The removed and modified disclosures were adopted on a retrospective basis and the new disclosures were adopted on a prospective basis. Our adoption of ASU No. 2018-13 effective April 1, 2020 did not impact our disclosures. In August 2018, the FASB issued ASU No. 2018-15, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The ASU addresses how entities should account for costs associated with implementing a cloud computing arrangement that is considered a service contract. Per the amendments of the ASU, implementation costs incurred in a cloud computing arrangement that is a service contract should be accounted for in the same manner as implementation costs incurred to develop or obtain software for internal use as prescribed by guidance in ASC 350-40. The ASU requires that implementation costs incurred in a cloud computing arrangement be capitalized rather than expensed. Further, the ASU specifies the method for the amortization of costs incurred during implementation, and the manner in which the unamortized portion of these capitalized implementation costs should be evaluated for impairment. The ASU also provides guidance on how to present such implementation costs in the financial statements and also creates additional disclosure requirements. The amendments are effective for fiscal years beginning after December 15, 2019. The amendments in this ASU can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Our adoption of ASU No. 2018-15 effective April 1, 2020 did not have an impact on our condensed consolidated financial condition and results of operations. Pronouncements not yet implemented In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures and add disclosure requirements identified as relevant. The amendments are effective for fiscal years ending after December 15, 2020 and the amendments should be applied retrospectively to all periods presented. We are currently evaluating the impact of ASU No. 2018-14 and we anticipate that our adoption of this ASU will not have a material impact on our disclosures due to the termination of our U.S. pension plan in the prior year. In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes: Simplifying the Accounting for Income Taxes." The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions and adding some requirements regarding franchise (or similar) tax, step-ups in a business combination, treatment of entities not subject to tax and when to apply enacted changes in tax laws. This ASU is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. Early adoption is permitted. Our initial assessment of this ASU indicates it will not have a material impact on our consolidated financial condition and results of operations, but our assessment has not been completed. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This update provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and LIBOR. This ASU includes practical expedients for contract modifications due to reference rate reform. Generally, contract modifications related to reference rate reform may be considered an event that does not require remeasurement or reassessment of a previous accounting determination at the modification date. This ASU is effective immediately; however, it is only available through December 31, 2022. We are currently evaluating the potential impact of this ASU on our consolidated financial position and results of operations. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and. Economic Security ("CARES") Act, which, along with earlier issued Internal Revenue Service ("IRS") guidance, contains numerous provisions that may benefit us, including the deferral of certain taxes. The relevant tax implication impacting us is the correction of a technical issue introduced in the Tax Cuts and Jobs Act to provide for fifteen-year useful life and allow bonus depreciation for qualified improvement property. These changes were included in the fixed asset calculations for the tax year ending March 31, 2020, and we amended the tax return for the year ending March 31, 2019 to include this effect. We continue to assess the effect of the CARES Act and ongoing government guidance related to COVID-19 as it is issued.

(“Petersen”), based near Tampa, Florida, for $11.8 million, of which $11.5 million was paid at closing and funded through our revolving credit facility, and the remaining $0.3 million represented a working capital adjustment paid in July 2019. Petersen is a leading designer, manufacturer and installer of architecturally-specified, engineered metal products and railings, including aluminum and stainless steel railings products for interior and exterior applications. The excess of the purchase price over the fair value of the identifiable assets acquired was $6.1 million allocated to goodwill, which will be deductible for income tax purposes. Goodwill represents the value expected to be obtained from enabling geographic, end market and product diversification and expansion as Petersen is a strategic complement to our existing line of architecturally-specified building products. The allocation of the fair value of the net assets acquired included customer lists of $3.2 million and backlog of $0.4 million, as well as accounts receivable, inventory and equipment of $2.2 million, $0.8 million and $0.7 million, respectively, net of current liabilities of $1.5 million. Customer lists are being amortized over 15 years, backlog is amortized over 1.5 years and goodwill is not being amortized. Petersen activity has been included in our Industrial Products segment since the acquisition date. No pro forma information has been provided due to immateriality.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS During the quarter ended December 31, 2017, we commenced a sale process to divest our Coatings business to allow us to focus resources on our core growth platforms. Our Coatings business manufactured specialized industrial coating products including urethanes, epoxies, acrylics and alkyds. As of December 31, 2017, the Coatings business met the held-for-sale criteria under ASC 360, "Property, Plant and Equipment," and accordingly, we classified and accounted for the assets and liabilities of the Coatings business as held-for-sale in the accompanying condensed consolidated balance sheets, and as discontinued operations, net of tax, in the accompanying condensed consolidated statements of income and cash flows. We completed an initial assessment of the assets and liabilities of the Coatings business and recorded a $46.0 million impairment based on our best estimates as of the date of issuance of financial results for the quarter ended December 31, 2017. No adjustments to previously recorded estimates have been made. On July 31, 2018, we consummated a sale of assets related to our Coatings business to an unrelated third party, the terms of which were not disclosed due to immateriality. During the three months ended September 30, 2018, we received an aggregate of $6.9 million for the sale of assets related to our Coatings business in multiple transactions. This resulted in gains on disposal of $6.9 million due to write-downs of long-lived assets in prior periods. On March 17, 2020, we completed the sale of the last remaining real property owned by the Coatings business to an unrelated third party, the terms of which were not disclosed due to immateriality. The sale resulted in proceeds and a gain on disposal of $1.5 million due to write-downs of long-lived assets in prior periods. The last remaining asset of the Coatings business is a long-term lease that expires in March 2027. We were unable to terminate the lease, but we have sub-let the property for the remainder of the lease term. As such, this lease was moved back into continuing operations, effective March 31, 2020, and the related right-of-use ("ROU") assets and lease liabilities were reported as continuing operations as of March 31, 2020. Summarized selected financial information for the Coatings business for the three and six months ended September 30, 2020 and 2019 is presented in the following table (in thousands): Three Months Ended September 30, Six Months Ended 2020 2019 2020 2019 Revenues, net $ — $ — $ — $ — Loss from discontinued operations before income taxes — (69) — (224) Income tax benefit — 34 — 50 Loss from discontinued operations, net $ — $ (35) $ — $ (174)

For the six months ended September 30, 2020, we earned $37.2 million from continuing operations before taxes and provided for income taxes of $8.9 million, resulting in an effective tax rate of 23.8%. The provision for income taxes differed from the statutory rate for the three and six months ended September 30, 2020 primarily due to state income taxes, excess tax deductions related to stock compensation, a change in indefinite reinvestment assertion related to the investment in a foreign subsidiary, foreign tax credits, adjustments related to state tax returns and state R&D credits, the provision for global intangible low-taxed income ("GILTI") and an increase in the reserves for uncertain tax provisions. For the three months ended September 30, 2019, we earned $12.5 million from continuing operations before taxes and provided for income taxes of $3.6 million, resulting in an effective tax rate of 29.2%. For the six months ended September 30, 2019, we earned $32.2 million from continuing operations before taxes and provided for income taxes of $8.0 million, resulting in an effective tax rate of 24.9%.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2020 (“Quarterly Report”), include all revenues, costs, assets and liabilities directly attributable to CSWI and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSWI’s financial position as of September 30, 2020, and the results of operations for the three and six month periods ended September 30, 2020 and 2019. All adjustments are of a normal, recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSWI’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020 (the “Annual Report”).
Current Expected Credit Losses (CECL)	Current Expected Credit Losses ("CECL") - We record an allowance for credit losses on trade receivables that, when deducted from the gross trade receivables balance, presents the net amount expected to be collected. We estimate the allowance based on an aging schedule and according to historical losses as determined from our billings and collections history. This may be adjusted after consideration of customer-specific factors such as financial difficulties, liquidity issues or insolvency, as well as both current and forecasted macroeconomic conditions as of the reporting date. We adjust the allowance and recognize credit losses in the income statement each period. Trade receivables are written off against the allowance in the period when the receivable is deemed to be uncollectible. Subsequent recoveries of amounts previously written off are reflected as a reduction to periodic credit losses in the income statement.
Accounting Developments	Accounting Developments Pronouncements Implemented In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The ASU requires, among other things, the use of a new current expected credit loss model in order to determine an allowance for credit losses with respect to financial assets and instruments held. The CECL model requires that we estimate the lifetime of an expected credit loss for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. On April 1, 2020 we adopted the ASU on a prospective basis to determine our allowance for credit losses in accordance with the requirements of Topic 326, and we modified our accounting policy and processes to facilitate this approach. Our primary exposure to financial assets that are within the scope of CECL are trade receivables. Our adoption of ASU No. 2016-13 effective April 1, 2020 did not have a material impact on our condensed consolidated financial condition and results of operations. In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendments of the ASU modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosure requirements for assets and liabilities measured at fair value in the statement of financial position or disclosed in the notes to the financial statements. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal year 2020 permitted for the new disclosures. The removed and modified disclosures were adopted on a retrospective basis and the new disclosures were adopted on a prospective basis. Our adoption of ASU No. 2018-13 effective April 1, 2020 did not impact our disclosures. In August 2018, the FASB issued ASU No. 2018-15, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The ASU addresses how entities should account for costs associated with implementing a cloud computing arrangement that is considered a service contract. Per the amendments of the ASU, implementation costs incurred in a cloud computing arrangement that is a service contract should be accounted for in the same manner as implementation costs incurred to develop or obtain software for internal use as prescribed by guidance in ASC 350-40. The ASU requires that implementation costs incurred in a cloud computing arrangement be capitalized rather than expensed. Further, the ASU specifies the method for the amortization of costs incurred during implementation, and the manner in which the unamortized portion of these capitalized implementation costs should be evaluated for impairment. The ASU also provides guidance on how to present such implementation costs in the financial statements and also creates additional disclosure requirements. The amendments are effective for fiscal years beginning after December 15, 2019. The amendments in this ASU can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Our adoption of ASU No. 2018-15 effective April 1, 2020 did not have an impact on our condensed consolidated financial condition and results of operations. Pronouncements not yet implemented In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures and add disclosure requirements identified as relevant. The amendments are effective for fiscal years ending after December 15, 2020 and the amendments should be applied retrospectively to all periods presented. We are currently evaluating the impact of ASU No. 2018-14 and we anticipate that our adoption of this ASU will not have a material impact on our disclosures due to the termination of our U.S. pension plan in the prior year. In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes: Simplifying the Accounting for Income Taxes." The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions and adding some requirements regarding franchise (or similar) tax, step-ups in a business combination, treatment of entities not subject to tax and when to apply enacted changes in tax laws. This ASU is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. Early adoption is permitted. Our initial assessment of this ASU indicates it will not have a material impact on our consolidated financial condition and results of operations, but our assessment has not been completed. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This update provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and LIBOR. This ASU includes practical expedients for contract modifications due to reference rate reform. Generally, contract modifications related to reference rate reform may be considered an event that does not require remeasurement or reassessment of a previous accounting determination at the modification date. This ASU is effective immediately; however, it is only available through December 31, 2022. We are currently evaluating the potential impact of this ASU on our consolidated financial position and results of operations. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and. Economic Security ("CARES") Act, which, along with earlier issued Internal Revenue Service ("IRS") guidance, contains numerous provisions that may benefit us, including the deferral of certain taxes. The relevant tax implication impacting us is the correction of a technical issue introduced in the Tax Cuts and Jobs Act to provide for fifteen-year useful life and allow bonus depreciation for qualified improvement property. These changes were included in the fixed asset calculations for the tax year ending March 31, 2020, and we amended the tax return for the year ending March 31, 2019 to include this effect. We continue to assess the effect of the CARES Act and ongoing government guidance related to COVID-19 as it is issued.
