Easy to create a fantastic shower

 on November 27, 2012

Initially I was going to do an old school mud type shower but after looking and listening to plenty of experts in the tile working field I decided to try the Kerdi shower system. I applied the Kerdi directly over drywall per the instructions. I even went ahead and bought the 1/8″ square notch trowel. You do have to work fast so the thinset doesn’t start to dry before you apply the Kerdi. I precut all the pieces before I started. Then I mixed enough unmodified thinset to do one wall. Dampen the drywall with a sponge before you apply the thinset. Overall the product was pretty easy to use if you follow the instructions. There are some good youtube videos you can find as well. My shower turned out great. I shared pictures so you can check them out in the product pictures.

No Leaks Happening Here

I am doing my very first shower installation and this product was recommended. I went with the entire Kerdi system and while it is a bit time consuming I know that my shower will not leak. I felt it worth it as I didn’t want to have to tear down any of my tile to have to repair a leak in the future. I had never done this before and it was really easy but just took time to get it correct. Their system makes it simple.

Product is Great! Contractor Not So Much…

This is wonderful stuff. Sadly the contractor who built the shower put it BEHIND the backer board. Shower will have to be completely rebuilt.

Love it!

I’ve been using Kerdi for years. This stuff is great. I’ve never had a shower leak when I combine Duroc and Kerdi, with the Kerdi overlaying the junction between two boards of Duroc. I particularly like the hairy, or fibrous, material on the tile side of the Kerdi. Tile just sticks. The Kerdi also provides just the smallest amount of movement so there seems to be less to zero cracking as the house groans and creaks. Especially in older homes.

Real pain to put up. Definitely good quality.

Real pain to put up. Definitely good quality, flexible, strong and thick. Do Be smart and follow Schluter’s instructions.

It works!

Outstanding membrane for tile installation. I am fully confident that my shower walls are 100% waterproof if something should get through my grout or tile. Installs quickly and easily. Would definitely buy again.

Excellent product. I’ve used it for years on many bathtub showers and never had an issue. A must for any tile install in wet areas
