Custom Crack Buster Mat Underlayment

Take a look at our Membrane Underlayment Guide for more information on the different types of underlayments.

Custom Crack Buster Mat Underlayment is a self-bonding fabric and asphaltic mat designed to reduce crack transmission in ceramic tile or stone floors in extra heavy duty commercial installations. Use as an anti-fracture membrane to bridge horizontal cracks up to 3/8" (9.5 mm) in full floor thin-set applications or as a crack isolation membrane when an individual crack is bridged with the membrane.

Its uniquely designed surface texture allows secure bonding of all types of tile and stone. High strength peel-and-stick backing allows quick and easy application to virtually any substrate. Suitable for all interior or exterior, heavy-duty commercial tile and stone installations. Protected by MoldGard™ Technology to resist mold and mildew growth.

Item Code# CBMP36

Use on ceramic tile of all types including impervious porcelain, natural stone & Terrazzo.
