Disclaimer: I am not a tile expert. just a regular DIY-er, and have only done a few small tiling jobs in my life. \r\n\r\nI went in to find Ditra, but all they had was RedGard, so I decided to give it a try in my bathroom with 12x24 inch floor tiles. It was very easy to handle and cut, and went in place with little hassle. I only had one seam on the non-tub half of the bathroom.\r\n\r\nA couple things to note: make sure your mortar bed has even coverage, and be sure to press the product firmly into the bed. Use a roller if possible. I actually used a regular wooden rolling pin from the kitchen, and it was very helpful. Due to my lack of experience, I had a few areas where the mortar was too think, causing a bump. I was able to roll the excess out the side of the mat, much like an air bubble.\r\n\r\nRedGard says you can tile on top right away, but I let it set up until the next day. For each section of tile, I used a regular wide putty knife to lay the first coat of mortar to fill the "dimples," then a 1/4 inch square notched trowel to lay down the final bed. The RedGard was firmly bonded to the subfloor. I grouted the next day; that was 2 days ago, and don't see any issues with the grout. My grout lines are very narrow, so I'm not sure if that helps, or why others reported issues with grout.\r\n\r\nI am very pleased with how the job came out, and everything feels very solid. No one will think Bob Vila or Mike Holmes laid my tile, but any flaws in the job are due to my inexperience, not the uncoupling mat. I plan on using it for my other bathroom next year. Of course I can't predict how it will hold it up long term, but I don't see anything so far that concerns me.
