How do I Reface Gas Fireplaces?

Clean the bricks of the gas fireplace with a mild detergent and water. Let the brick dry thoroughly after cleaning.

Measure the area to be tiled with a measuring tape. Transfer the measurements to the sheet of cement backerboard. Cut the backerboard to size by scoring it with a utility knife and snapping it from the opposite side.

Apply construction adhesive directly to the front of the brick on the fireplace. Place the cement backer board on top of the construction adhesive. Allow the adhesive to dry overnight or according to the manufacturer's directions.

Determine a layout for the tile. Spread thin set mortar on the cement backer board with a notched trowel. Begin placing the tile into the thin set mortar. Start at the bottom of the fireplace and work up so the tiles don't slip out of place before the mortar dries. Place tile spacers between each tile. Use a tile saw to cut tiles to size. Allow the mortar to dry overnight.

Take the tile spacers out from between the tiles. Spread tile grout over the tiles with a grout float. Remove extra grout with a grout sponge. Let the grout dry for several days before operating the gas fireplace.
