## Questions & Answers

**Q: Can this be used to water proof a leak on existing shower tile?**
A: No.  This product is for waterproofing the substrate behind the tile.  You may need to peel off  the tile to get to the substrate.  But it seems you need to find the source of the leak first then use this product as part of the repair.

**Q: what tape to use?**
A: I used the mesh tape for Durock and went over all joints with the mortar mix I planned to use installing my tiles. Let the mortar dry completely. Then, just follow the directions on the bucket. I tackled a shower surround with two large niches for my first tile job. This bucket was plenty for two coats on everything as well as a section on the floor in front of the shower. Great product and easy to use. Be sure to follow the directions carefully.

**Q: I have cement subfloor in my shower . Can I use this instead of a shower pan liner?**
A: Hi, A liner would be preferable, but this membrane will work too, assuming the concrete is stable, there is a natural slope to the drain and there are no breaches.  If you use a Durock shower installation kit it adds a natural slope to a center drain installation.  That would be preferable then use the Durock membrane over the top before using mastic and tiling.

**Q: Is this like flex seal liquid?**
A: If you are referring to the “flex seal brand” sealer that is on the market it doesn’t compare.This liquid waterproof membrane is like a very thick paint that goes on smooth with roller or brush.this is a very good product that I have used on several occasions..... it provides excellent waterproofing qualities if used as directed p,usually two coats will do the trick.

### ⭐⭐⭐⭐⭐ Great for waterproofing

### ⭐⭐⭐⭐⭐ If it could get wet, paint it with this stuff!
*by S***H on June 21, 2019*

This was the first time I have ever used this product, but I would definitely use it again. We remodeled our bathroom and installed a shower. I had no issues with any overpowering smell, cleaning up was easy as long as you do it before it dries. I bought the really cheap paint brushes for this and threw it away after I was done with it. I also had a fan running for venting the bathroom (I had been told that it might be smelly because the red waterproofing from another company is very smelly). I ended up putting three coats on the walls. The stuff works, found it out the hard way. I didn't paint the drywall alongside the shower, just the cement board, and my tiles ended up extending a tiny bit over onto the drywall. Before I painted the walls, I taped off the tile trim to keep it clean, painted and then removed the tape only to have it pull all of the paint off the drywall all the way down to the drywall mud. That's when we realized that the wall was wet still from the tile. We left it to dry for a few days, added a thin coat of mud, additional drying time and repainted. Next time I'll be sure to cover everything that could possibly come in contact with tile! This stuff was super easy to put on the walls, just brush it into the corners and roll the walls. Really bright blue!
