To waterproof plaster walls in a shower, you should start by ensuring the wall is clean, dry, and free from any loose material. Apply a primer specifically designed for high moisture areas, followed by a waterproof membrane; these are often in liquid form and can be applied with a brush or a roller. Ensure the entire surface is covered, paying extra attention to corners and edges where water infiltration is more likely. After drying, seal the deal with a waterproof paint to add an extra layer of protection.
