How to Offset an Outlet Tile Backsplash

Measure the area of your desired backsplash, including the diameter of any plugs, outlets or features. Include the size and shape of any plates or covers.

Cut a piece of butcher or Kraft paper to size using the scissors, and with the pencil, mark in the placement of any plugs, outlets or features. Use the ruler and T-square, if desired, to get straight lines and measurements.

Place the tiles onto the paper, moving them around until you achieve the pattern and coverage desired for your backsplash. Leave a 1/8- to 1/10-inch gap between the tiles to allow for grout application. Trace around each tile lightly with the pencil to create a map for installation.

Mark the areas that need to be trimmed away on the tiles that would cover the plugs, outlets or features using the grease pencil.

Trim the tiles as necessary using the utility knife – for plastic or linoleum tiles -- or diamond cutting tool – for glass, ceramic and porcelain tiles – on the cutting surface.

Remove the plug and outlet plates or covers from the backsplash area, and then sand the area using 80-grit sandpaper. This creates a toothy, even surface for tile placement.

Wipe the sanded area with a damp rag to remove dust, dirt and old paint.

Apply a thin layer of mastic across the area using a putty knife.

Place the tiles onto the backsplash area, pressing each tile into the mastic, following your paper map.

Allow the tiles to set in the mastic overnight, and then fill the gaps between the tiles with grout. Wipe away excess grout using a damp rag.

Let the grout dry, following the manufacturer’s instructions, and then replace the plug and outlet plates or covers.
