Strong Strip


Think of Strong Strip as The Shield’s super sturdy sidekick. Strong Strip is made out of the same tough material as The Shield, but in 5″ wide strips. Strong Strip is best used when sealing sheets of The Shield together, or creating a 100% waterpoof barrier between floor and wall. Best of all, Strong Strip is anti-microbial – making it the ultimate weapon against Monster Mold.

Strong Strip can be easily cut to the length you need. Fun Fact: It holds its shape so well, that it can also be cut and molded into corners for shower installation. Tile may be installed directly over Strong Strip using thin set mortar. For best installation results, check out one of our Super Clear Instruction Sheets.
