Tile thinset is a cementitious based compound, and like any cement based product, it requires water to set properly.

Can you tile straight onto painted walls?

“Painted surfaces are generally unsuitable for tiling; a detailed examination of the painted surface should be made to decide whether it is suitable. Emulsion paint, lime-wash, distemper and similar finishes should be removed since they can possess poor adhesion to backing. Solvent based adhesives should not be used”.

A: It’s perfectly acceptable to put tile directly on concrete — with a couple of caveats. First, it is important to determine if there is moisture coming up from the slab. Those products should help prevent any cracks in the slab from damaging the newly installed tile.

Do you need underlayment to install tile on concrete?

Although you don’t need to install an underlayment between the concrete and the tile, you need to prepare the surface before placing the tile.

What kind of subfloor is needed for ceramic tile?

Exterior-Grade Plywood Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.

Can I lay tile directly on plywood?

Tile can be laid on plywood. But do not install tile directly on the plywood subfloor itself. Use an intervening layer of a sheet of thinner plywood.
