Many new homeowners ask: can you tile directly on EPS Cement Sandwich Wall Panel for bathroom and kitchen walls? The answer is yes, but you need to follow the correct steps to avoid tiles falling off later. First, make sure the surface of the EPS Cement Sandwich Wall Panel is completely clean, dry, and free of any dust or loose debris. Wipe the whole panel surface with a damp cloth 24 hours before you start tiling.

You must use a flexible thin-set mortar specially designed for cement board, not regular cement mortar, to stick tiles on EPS Cement Sandwich Wall Panel. Regular hard mortar cannot absorb the small natural structural shifts of the EPS Cement Sandwich Wall Panel, which will cause the tiles to crack or fall off after a few months. The flexible mortar will move slightly with the EPS Cement Sandwich Wall Panel, keeping the tiles firmly attached for decades.

For bathroom walls that are exposed to constant water, it is recommended to apply a layer of waterproof membrane on the EPS Cement Sandwich Wall Panel before you apply the thin-set mortar. This extra step will make your wall 100% waterproof, and prevent any moisture from seeping behind the tiles. Thousands of homeowners have already used this method to build fully tiled bathroom walls on EPS Cement Sandwich Wall Panel, with zero tile failure issues after more than 10 years of use.
