       FSI ANNOUNCES FIRST QUARTER, 2018 FINANCIAL RESULTS Conference call
             scheduled for Wednesday May 16th, 11:00am Eastern time,
                               8:00am Pacific Time
                            See dial in number below


VICTORIA,  BRITISH COLUMBIA,  May 15, 2018 - FLEXIBLE  SOLUTIONS  INTERNATIONAL,
INC. (NYSE Amex:  FSI,  FRANKFURT:  FXT), is the developer and  manufacturer  of
biodegradable  polymers  for oil  extraction,  detergent  ingredients  and water
treatment as well as crop nutrient  availability  chemistry.  Flexible Solutions
also  manufactures  biodegradable  and  environmentally  safe  water and  energy
conservation technologies. Today the Company announces financial results for the
first quarter (Q1) ended March 31, 2018.

Mr. Daniel B. O'Brien, CEO, states, "First quarter results were reasonable but
we hope to do better in the future. Earnings were flat, even with the top line
miss, due to product mix and cost control." Mr. O'Brien continues, "Subsequent
to the end of the quarter, we received the final insurance payment from the
Taber fire. This improves our cash on hand by about $2.4 MM US. Details are in
note 5 of the financials."

     o    Sales in the first quarter (Q1) were  $4,201,180,  down  approximately
          10% when compared to sales of $4,663,708 in the corresponding period a
          year ago. The  financials  show a Q1, 2018 net income of $703,664,  or
          $0.06 per share, compared to a net income of $3,252,667,  or $0.28 per
          share,  in Q1, 2017.  An insurance  claim payout of  $2,572,288 in Q1,
          2017 is the reason for the large discrepancy in the year over year net
          income. If one were to remove the insurance payout from net income the
          year over year Q1 net incomes would be very similar.

     o    Basic  weighted  average shares used in computing per share amounts in
          Q1 were 11,620,291 and 11,458,170 for both 2018 and 2017 respectively.

     o    Non-GAAP  operating cash flow: For the 3 months ending March 31, 2018,
          net income  reflects  $85,400 of non-cash  charges  (depreciation  and
          stock option  expenses),  Income tax, Deferred income tax, Net gain or
          loss from insurance payout and/or write down of inventory,  as well as
          Interest  income;  which are items not related to operating or current
          operating activities.  When these items are removed, the Company shows
          operating cash flow of $1,096,979,  or $0.09 per share.  This compares
          with  operating cash flow of  $1,155,828,  or $0.10 per share,  in the
          corresponding 3 months of 2017 (see the table that follows for details
          of these calculations).

The NanoChem  division  continues to be the dominant  source of revenue and cash
flow for the Company. New opportunities  continue to unfold in detergent,  water
treatment,  oil field  extraction and agricultural use to further increase sales
in this  division.  In past  years the  NanoChem  division  sales have been less
volatile  quarter over quarter,  however due to increasing sales to agriculture,
revenue seasonality may become larger.
