Re: What is this? Cardboard??


You do undertand that cemete board of not water proof, much less even water resistant. It is stamped on the board moisture resistant. That should not be used in a bathroom in the shower area. You will be replacing it in a couple years. Water will soak thru the tile grout, and into the cement board. You will first notice tiles starting to buldge out and become loose. Use a fully waterproof product like Schleuter waterproofing products.
