Review: Best price, good quality, many uses - Good quality, great price. Used with Red Guard on all seams and over 1/2 inch space between mud bed and Durarock walls preventing water migration into your walls and bench. Do NOT set Durarock in the mud bed. Material is thicker than ones I used before but goes on well absorbing the RG. Being thicker use a more generous amount of RG to give good bondage to the Durarock. Will take more time to dry but that is OK, do not rush water membrane procedures.
Review: Same quality as brand name, just has a better price. - Much more affordable than buying the brand name stuff at a local hardware store. It seems to be same quality works well with redguard. Used in all inner and outter corners with redgaurd to seal new shower.

### ⭐⭐⭐⭐ Used for waterproofing seams, not a crack prevention membrane
*by P***3 on April 7, 2023*

This is not an adhesive or membrane tape. Its simple a strip of a porous fiber material used for waterproofing seams in wet applications. I used it to seal up a shower pan and curb, used regard as the substrate for adhesive, crack prevention, and waterproof. This just covered up a bunch of screwholes and helped seal the bottom pan seam. It worked just fine. Its nothing to rave about, but it served its purpose for what i needed it for.
