Using RedGard as a Crack Prevention Membrane



Written on June 26, 2008 – 5:34 pm | by jaygaulardcom |


Yesterday was pretty fun. I met the installer at America in West . I picked out the for the and the grout color. I like the grout to match the , so the doesn’t look like a big . We also ordered up the .

I bought 473.44 square feet of 13″x13″ Classic Wheat commercial grade . That’s a lot of . I also bought 60lbs of Avalanche colored grout. Lastly, I bought 100 lbs of Ultraflex polymer modified mortar.

The guys are coming tomorrow to start the installation. The nice thing is they are going to pick up all the materials before coming here in the morning. They have a truck…I don’t. If I did, trust me…I would be at getting the 67 cent per square foot . Oh, the price I pay for delivery. I had actually contemplated installing all the myself. Then, I thought better of it. I think I would do a good job, but then again, who is going to do my computer work for me that day? I prefer to work at what I do and let others work at what they do. The door installation validated that.

Last night, I had a few small things to take care of in the . I had to trim up the bottoms of the door and apply a prevention membrane on parts of the concrete .

I used my and cutting disk to cut through two and a half . The first two went very well. About half way through the third one the started sounding like popcorn. I looked down and smoke was pouring out of the motor. The whole thing felt so familiar. Man, it stunk!!! Yeah, I guess I blew up my . I will have to check my receipt to see if it’s still under warranty. To finish the job, I used my reciprocating saw, which I should’ve used the whole time. It worked great.

After that, I gave the whole a nice cleaning. I swept and vacuumed. If there are any cracks in the , you need to use some sort of a membrane. I have actually heard of people using for this, but I chose to use RedGard. I got two gallons at yesterday. The other option was to use Schluter®-DITRA, but I didn’t think I needed that. The only thing that is wrong with the is a hairline about five feet long. You can hardly notice it. I tried to stay on the safe side.

RedGard is very cool stuff. It has the consistency of yogurt and can be applied with a brush, roller or sprayer. It goes on pink and dries red. After it dries, it’s like a layer of plastic. People use is for a membrane and waterproofer. I am sure you can find other uses for it too.

I basically needed to use it for that one , but decided to put it around all the concrete expansion joints too. I believe that you aren’t supposed to over expansion joints. You up to them and keep the joint. From what I am reading, people right over everything, while using no preparation and the lasts for 100 years. It’s only us who analyze the thing to death that have issues. I am going to see what the installer’s experience tells me. After all, he is the expert with the picture book of hundreds of jobs.

I’ll take some pictures tomorrow of the installation.
