All Flexco products (except Flex-Tuft®) were tested for resistance to various chemicals by placing one cubic centimeter of each chemical on the tile surface and then covering it with a watch glass. The chemicals were allowed to remain in contact with the tile for one hour and for twenty-four hours. The tiles were then washed with soap and water and allowed to dry under room conditions for twenty-four hours. Visual evaluations were then made and classified as follows:
(1) "No change" indicated that the chemical had no visible effect upon the tile or that the effect would be eliminated in the course of ordinary maintenance
(2) "Surface dulling" indicated that the tile suffered loss of gloss
(3) "Surface attack" indicated that the tile suffered damage such as warping, swelling, blistering, peeling, and raised or roughened areas
(4) "Stain" indicated tile discoloration.
