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!!

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 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.

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!

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.

Rated 5 out of 5 by from Good stuff I used this to waterproof a niche in a shower wall. It was applied in the area over concrete board. After finding that I had high spots on the mortaring and had to grind it down, I found a reassuring membrane in the part that I grinded away. I have pending peace of mind that this is water-tight.

I bought this one and trusted it because of so many positive reviews here. I followed the instruction and used it on Hardie cement board. After a few days, I checked on it and I was so surprised to find out that I could peel off some areas just like peeling off an old paint. It didn't I contacted their customer service and they recommended to apply a primer coat prior to two full coats. Their recommendation wasn't even on the manual and It was clearly not a user mistake. I had to spend a few hours to peel it off from the shower wall on a small bathroom size. No refund/replacement. I bought Ardex 8+9 waterproofing compound and hoped that it would work based on some suggestions online for Hardie cement board. WOW! It was a huge different compared to RedGard. It sticked really well on Hardie cement board. It even sticked on my t-shirts, pants, and other materials. The smell was not as strong as RedGard. The dark grey color was nice too compared to RedGard bright red color. The most important different was the texture. The dried membrane had a rough texture good for bonding with cement. RedGard had a smoother soft plastic-like texture. I would highly recommended Ardex 8+9 on Hardie cement board. Their customer service was fast and helpful when I called them for some questions.
