Before tiling shower walls, it is essential to apply a waterproofing membrane over the bare walls. This membrane protects the walls from water damage and mold growth. Typically, you’ll first need to ensure the walls are clean, dry, and smooth. Apply a thin-set mortar to adhere the waterproofing fabric at corners and seams, then coat the walls with a liquid waterproofing membrane, making sure to follow the manufacturer's instructions for application and curing times. Priming the walls might also be necessary depending on the type of substrate and waterproofing product used.
