To waterproof drywall before tiling a shower, start by applying a waterproofing primer to create a sealed surface. After the primer dries, install a waterproof membrane, such as a liquid or sheet membrane, over the drywall, making sure to cover all surfaces thoroughly. Overlap seams and corners carefully to prevent water penetration. Once the membrane is securely in place and has cured, you're ready to proceed with tiling, ensuring a durable and waterproof shower environment.
