How to Build a Raised Hearth for a Gas Fireplace

A raised hearth provides a stylish and functional platform for your gas fireplace. It elevates the firebox, creating a more visually appealing focal point and improving heat distribution throughout the room. Here's a step-by-step guide to help you build a raised hearth for your gas fireplace:

Materials Required:

* Fire-resistant backer board * Cement board * Mortar * Tile or stone * Grout * Thinset * Trim molding * Nails or screws

Step 1: Prepare the Base

* Remove any existing flooring or materials from the hearth area. * Level the floor and ensure it's flat and stable. * Install a layer of fire-resistant backer board to create a base for the hearth. Secure it with nails or screws.

Step 2: Build the Framing

* Frame the raised hearth using 2x4 or 2x6 lumber. The height of the framing should match the desired height of the hearth. * Ensure the framing is level and square.

Step 3: Install the Cement Board

* Cover the framing with a layer of cement board. Use thinset to secure the cement board to the framing. * Smooth out any excess thinset and allow it to dry completely.

Step 4: Tile or Stone the Hearth

* Lay out the tiles or stone on the cement board to determine the pattern and fit. * Apply thinset to the cement board and press the tiles or stone into place. * Use spacers to ensure even spacing between the tiles or stone.

Step 5: Grout the Tiles or Stone

* Once the tiles or stone are set, apply grout to the joints. Use a grout float to spread the grout evenly. * Wipe away any excess grout and smooth the joints with a damp sponge.

Step 6: Install the Trim Molding

* Cut the trim molding to fit around the perimeter of the hearth. * Secure the trim molding with nails or screws. * Caulk the joints between the trim molding and the hearth to prevent water damage.

Step 7: Install the Gas Fireplace

* Insert the gas fireplace into the opening in the raised hearth. * Connect the gas line and electrical connections according to the manufacturer's instructions. * Secure the fireplace in place.

Tips:

* Choose tiles or stone that are non-porous and heat-resistant. * Allow ample time for the thinset and grout to dry before using the fireplace. * Seal the grout and tile or stone with a penetrating sealer to protect it from moisture and stains. * Keep flammable materials away from the hearth. * Have the gas fireplace and hearth inspected regularly by a qualified professional.
