Why use SimpleMat instead of thin-set mortar or mastic adhesive?
SimpleMat is cleaner, easier, and faster. There is no mixing of powder, there are no special tools needed to apply the mat, and there is no mortar clean-up. Also, thin-set can take 16-18 hours to cure before you can start grouting the tile. With SimpleMat, there is no waiting at all, you can grout immediately.
