They will no doubt blame the installation an/or other factors. To blame the product would mean you have to rip up the tiles which will then damage the waterproofing, so you could never prove the product was defective- catch 22. Grout is NOT waterproof and is not designed to be. That is what the membrane and puddle flange is for. Also I also believe that the glue shouldn't be waterproof but porous. This allows the water under the tiles to flow down to the drain via the puddle flange. In theory, water resistant plasterboard should perform as well as cement based plasterboard but when the waterproofing fails, cement sheet won't be damaged. Not really an issue while under warranty if you used a builder as its their responsibility. However as I owner built, that's why I'm hoping for the best and crossing my fingers Re: Wet areas - Villaboard or Water resistant plasterboard? 19May 18, 2014 8:18 am JB1 Grout is NOT waterproof and is not designed to be.

Not only for waterproofing but also keep the grout on the floor tiles cleaner. Which one do can you recommend. The first one is a lot more pricier, but is it much better? Hi All, First time poster. I was hoping to get some advice on villaboard installation within a bathroom. I have installed villaboard before, in a laundry.
