Mortar beds are an especially effective method for flattening textured plaster walls. The first layer is roofing felt that’s stapled over the plaster. Because plaster is dense and hard, you’ll need a staple gun. The next layer is metal lath, which is coarse wire mesh sheeting, fastened to the wall with screws. Screws are better than nails, as they grip the wood lath and studs behind the plaster. The mesh lath texture holds mortar on the wall. Choose mortar that’s specified for mortar beds, and evenly spread it over the lath with a trowel. Scratching horizontal rows of texture across the face of the mortar bed using the notched edge of the trowel helps the tiles hold. Once the mortar bed is cured, install tile using thinset mortar.
