Strataflex Waterproofing Membrane

Strataflex waterproofing membrane seals the substrate against water before you set tile, protecting the structure in showers, wet rooms, and other wet areas. It is the waterproofing step that goes down over your prepped surface so moisture cannot reach the subfloor or wall behind the tile. It is built for tile assemblies where water is a constant.

Apply it to a clean, prepped substrate to form a continuous waterproof layer, then bond tile directly over it with thinset. It suits showers, tub surrounds, and floors that see water.

Pros never skip waterproofing behind tile in a shower, and Strataflex makes that layer straightforward. Tile Outlets stocks it for shower and wet-area tile jobs.
