To prepare drywall for shower tile, start by ensuring the drywall is clean, dry, and smooth. Apply a waterproofing membrane over the drywall, covering all surfaces that will come into contact with water. This membrane can be a paint-on liquid or a sheet membrane that you adhere to the wall. Be thorough around edges and corners. After the waterproofing membrane has fully cured, check for any gaps and fill them with thin-set mortar, smoothing it out to ensure a flat surface for tile installation. Lastly, allow the mortar to dry completely before beginning to install the tiles.
