To waterproof a shower wall, start by applying a layer of primer over the surfaces intended for tiling. Once dry, use a waterproofing membrane—either in liquid form or as a sheet that you apply directly to the walls, ensuring all surfaces are covered, especially corners and edges. Seal all seams with waterproofing tape, then apply a second layer of the waterproofing membrane over the tape. Allow to dry completely before proceeding with tile installation. This multilayer approach ensures a moisture-resistant barrier that prevents water damage behind tiles.
