To waterproof drywall, apply a waterproofing primer or sealer directly to the drywall. These products can be found at most home improvement stores. Ensure the surface is clean and dry before application. For areas with intense moisture, such as bathrooms, consider using waterproof paint or installing cement board instead of drywall for superior moisture resistance. Always follow the manufacturer's instructions for the best results.
