USG Liquid Waterproofing Membrane 1 Gallon

USG liquid waterproofing membrane is a roll- or trowel-applied coating that seals showers, wet areas, and floors before tile goes down, blocking water from reaching the substrate behind your tile. This 1-gallon container covers a smaller shower, a bench, or a curb, or tops off a larger job.

Apply it over cement backer board, concrete, and other approved substrates, working it into corners and over the reinforcing mesh at seams and change-of-plane joints. Roll or trowel on an even coat, let it set up, then add a second coat for full coverage before tiling.

A sound waterproofing layer is what keeps moisture out of the wall and subfloor, and USG is a name pros rely on for the wet-area step. Tile Outlets stocks the membrane and the mesh that goes with it.
