Preparing a bathroom wall for tiling involves several key steps to ensure a durable and waterproof finish. Start by cleaning the wall to remove any dirt, dust, or grease. Then, apply a coat of primer suitable for the wall surface (drywall, plaster, or cement board) to enhance the adhesive's grip. For areas prone to moisture, apply a waterproofing membrane over the primer, ensuring it fully covers the space where tiles will be. Allow each layer to dry thoroughly according to the product instructions before proceeding with the tiling.
