To waterproof plasterboard for tiling, you need to apply a waterproofing membrane. Firstly, ensure the surface is clean and dry. Apply a primer (if recommended by the membrane manufacturer) and wait for it to dry. Then, roll on or paint the waterproofing membrane over the plasterboard, focusing on corners and edges. Apply at least two coats, allowing drying between coats. Once dry, the plasterboard will be ready for tiling, offering a robust, moisture-resistant base that prevents water damage.
