Substrates are required to be structurally sound and free of foreign substances that will compromise the carpet or its installation. Patching compounds are required to be suitable for application. Select polymer-fortified patching compounds according to the carpet manufacturer’s instructions. (Refer to current version of ASTM E1155).
NOTE: Patched areas may be porous and highly alkaline, which will prevent adequate adhesive bond. For best results, prime patched areas. Consult patch manufacturer for primer recommendations and compatibility with adhesives.
