To tile over drywall, ensure the surface is clean, smooth, and dry. Thinset mortar is widely recommended for its strong bonding properties. First, apply a layer of thinset to the drywall with a notched trowel. Then, place the tiles onto the mortar, pressing firmly and using spacers for even gaps. After the mortar sets, apply grout between the tiles, wiping away any excess with a damp sponge. Finish by sealing the grout to prevent moisture damage. Use latex-modified thinset for areas with higher moisture, like bathrooms.
