Is Tavy Thin Skin Waterproof?

Tavy Thin Skin does what it says it will do.
I have used Tave Thin Skin to tile over a very sturdy (basically non-removable) polyurethane waterproofing coating on my cement basement floor. It adheres well to this surface and provides a concrete surface to which the mortar mix (thinset) will adhere quite well.

What is tile underlayment?

An underlayment is the solid stabilizing layer directly below the tile and the tile adhesive (usually a thinset mortar). Using the wrong one can spell disaster for your tile installation. View fullsize. These poor tiles were installed improperly; they never stood a chance.

Can I apply tile to 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.
