How do I Build a Frontier Fireplace Hearth?

Measure the front of the frontier fireplace with a measuring tape. Decide on how large the hearth needs to be. Typically, a fireplace hearth spans from one side of the fireplace to another and is 1 to 2 feet wide.

Mark the measurements on a piece of cement backer board. Cut the backer board along the marks with a jigsaw.

Apply construction adhesive to the back of the cement backer board. Set the backer board in place in front of the Frontier fireplace. Screw the backer board to the subfloor with screws and a screwdriver. Allow the glue to dry overnight.

Dry fit the tile on top of the cement backer board. Adjust the tiles on top of the backer board until you find a layout that you like. Place tile spacers between the tiles to maintain the markings. Mark a starting point for the installation of the tiles with a pencil. Remove the tiles.

Apply thin-set mortar to the top of the cement backer board with a notched trowel.

Place the tiles in the thin-set mortar. Set tile spacers between the tiles. Make needed cuts on the tiles with a tile saw. Place all of the tiles and let the tiles dry overnight.

Take the tile spacers out from between the tiles. Spread grout into the tile joints with a grout float. Remove any extra grout with a damp grout sponge. Allow the grout to dry overnight.

Spread a bead of caulk around the edges of the tile hearth. Smooth the caulk with your finger.
