Customer Questions & Answers

can I use this for an outdoor tiles porch

Asked by: cheo14e
Yes, but why is the reason? If you using it to prevent cracks from the floor to the tile is a good idea since the tile will set on the Redgard membrane and will flex.

I actually used a brush, first to do all the corners and seams, then to coat the rest. I put 2 coats on all the seams. Clean up was easy with water. I used it previously on my other shower floor. This time I used it on my entire master shower, walls and floor, seat, and niche. I even used it to re-coat a couple of my tools that had lost their rubber grips; worked like a charm! When the connection on my cord for charging my cell phone started to separate, I even used a Q-tip to put the redgard around the area. What great stuff!!

It is the simplest and best way to make a shower stall and pan waterproof. It is a great product to lay tile on to, all of your surfaces are flat and all your corners are square. I have not seen any sign of seepage, leakage, or water damage outside my shower install which was completed five years ago. I had a shower valve go bad and had to replace the valve, I cut open the wall behind the shower and found no signs of a RedGard failure. I will continue to use this product in future builds and I will recommend this product to all my friends.

I purchased this on the advice of a HD professional to be applied over new Hardi Board for a tub surround....no shower. I planned to tile the walls of this surround. It was fairly expensive, in my estimation. Upon getting home and reading the instructions, I found that you cannot use premixed tile adhesive with this product. As I had already purchased the tile adhesive, and did not want to purchase and mix another product, I returned the RedGard. As this is a tub-only installation, I deemed the use of this product to be unnecessary , but I believe it would be very good for use under the tile in a shower.

I first saw it at a tile store where they had coated the inside of a small cardboard box with RedGard and filled it with water. I was so fascinated by this that I had to go look at it each time I went in the store. It was there, holding water for months!

Did this in my shower remodel last night, so we will see how the tile adheres, but it was easy to put on. I did a primer coat first, which I just mixed some water with it and made it a thin consistency and painted it on. The primer coat was super messy and drippy. Then did 2 full coats not watered down, which is a pudding type consistency. The smell is strong but not horrible. It rolled on fine with a roller, and I used a brush for the corners. It dried really quickly (maybe a half hour in between coats). This is my first shower remodel, and I am a complete DIYer, and a girl, so hopefully it all turns out well. I have watched 5000 utube videos, and read a million online reviews, and forums to get to this point. So far this was the easiest part of the project so far.

I recently used this product on a bathroom shower tile project. 1 gallon was sufficient for the 3x5 shower. The application was painless and it creates an amazing, almost rubber like, membrane. I built a small box using leftover 2x4's and painted the interior to test it and it held the water with no leakage. My project isn't complete yet so I can't speak to the durability but it definitely gives me piece of mind.

My husband and I used it to seal a crack in our floor prior to installing tile in our kitchen. The only drawback was removing the mortar when we replaced the floor a few years later. The areas where the Redgard was installed were very difficult to remove. I guess this is a testament to how well it works though, so we will continue to use it on our residential remodel projects.

I had seen this used in residential new construction but it was my first time to use it myself. It goes on easy with a brush or roller. The bright color also makes it easy to see where you have missed spots. Two or thee coats are recommended and two seemed quite adequate to me. Coverage for me was a bit better than listed in the product description. I used it over pre-cleaned Hardiebacker and that may be why it went further than in some other situations. The texture it creates seemed to provide a good surface for thinset tile application with good adhesion. The color change during drying is pretty dramatic and lets you see where drying has taken place. Odor is minimal or modest and is more like an ammonia smell than paint. It's recommended to use nitrile gloves applying it and that seems like good advice since this stuff has strong adhesion. It cleans up easily with water and dried spots or drips that may escape your dropcloth clean up pretty easily too. The instructions are quite clear and don't follow those YouTube videos that show it only applied to joints and edges. Cement backer boards are NOT waterproof. Coat the entire surface and don't try to save a few bucks and end up with water/moisture going through the backer behind grout joints.
