Can You Apply a Kitchen Backsplash Directly to the Drywall?

Choosing Tile

• The first step in installing a kitchen backsplash is choosing the tiles. For kitchens, choose glazed tiles that will not absorb moisture or cooking spatters. Glazed tiles have a glass surface that holds up to cleaning with soap and water. When choosing tiles, visit several tile or home improvement stores to view a wider selection, including ceramic, glass, granite, stone or hand-painted tiles. When selecting tiles, find out what special tools or adhesives are needed to complete the job.

Preparation

• Even though you can apply tiles directly to a drywall surface, careful preparation will ensure satisfactory adhesion. Inspect the wall for water damage before you begin. If you suspect water damage, these sections of the drywall should be replaced. Remove outlet covers and switch plates. Sand the drywall lightly with 80-grit sandpaper to rough up the surface. Wipe the wall with tack cloth to remove any dust from the sanding to complete your wall preparation.

Installation

• Before beginning the installation process, lay out the tiles in the desired pattern. Spread tile mastic, a tile adhesive, to the drywall with a notched trowel. Spread the mastic over a space large enough for eight tiles at a time. Set the tiles in place and press firmly into the mastic. Use spacers to get even grout lines. Continue until the backsplash is completed. Cut tiles as needed to fit around outlets. Allow the tiles to set overnight.

Grouting

• After the tiles are set in position, it is time to apply grout. Use a sandless grout to avoid scratching the surface of the tiles. Spread the grout over the tiled surface with a rubber grout float. Pack the grout into the spaces between the tiles. Remove excess grout by scraping the float across the surface at a 45-degree angle. Wipe the surface with a damp sponge. After the grout sets for 30 to 45 minutes, wipe the entire surface with a damp cloth. Buff the tiles with a dry cloth to remove any remaining residue and return the shine. Apply tub and tile caulk in a color to match the grout along the seams between the tile and counter top and cabinets.
