To waterproof a wall above a shower, start by cleaning the wall thoroughly to remove any dirt or grease. Apply a waterproof primer suited for high-moisture areas. Once dry, use a waterproofing membrane; paint or roll it over the wall, ensuring complete coverage. For extra protection, apply a second coat after the first has fully dried. Finally, seal all edges and seams with waterproof caulk to prevent water intrusion. This multi-layer approach provides a robust barrier against moisture.
