How To Build A Concrete Fireplace Hearth

A concrete fireplace hearth is a great way to add style and function to your fireplace. It can help to protect your floor from heat damage and embers, and it can also create a more comfortable space for sitting and enjoying the fire. Building a concrete fireplace hearth is a relatively simple project that can be completed in a weekend.

Before you begin, you will need to gather the following materials:

Quikrete concrete mix
Sand
Gravel
Water
Forming boards
Rebar
Wire mesh
Trowel
Level

Once you have gathered your materials, you can begin building your concrete fireplace hearth.

Step 1: Prepare the area

The first step is to prepare the area where you will be building your concrete fireplace hearth. This involves clearing away any furniture or other objects that may be in the way, and then sweeping or vacuuming the floor to remove any dirt or debris.

Step 2: Build the forms

Next, you will need to build the forms for your concrete fireplace hearth. The forms will create the shape of the hearth, and they will hold the concrete in place while it cures.

To build the forms, you will need to cut four pieces of forming board to the desired size and shape of the hearth. You will then need to assemble the forms using screws or nails.

Step 3: Install the rebar and wire mesh

Once the forms are built, you will need to install the rebar and wire mesh. The rebar will help to strengthen the concrete, and the wire mesh will help to prevent cracking.

To install the rebar, you will need to cut it to the desired length and then bend it into a U-shape. You will then need to place the rebar in the forms, spacing it evenly.

To install the wire mesh, you will need to cut it to the desired size and then place it over the rebar. You will then need to secure the wire mesh to the rebar using wire ties.

Step 4: Mix the concrete

Once the rebar and wire mesh are installed, you can begin mixing the concrete. To mix the concrete, you will need to follow the instructions on the package of Quikrete concrete mix.

Once the concrete is mixed, you will need to pour it into the forms. Be sure to fill the forms completely and to smooth the surface of the concrete using a trowel.

Step 5: Cure the concrete

Once the concrete is poured, you will need to allow it to cure. The curing process will take several days, and during this time you should keep the concrete moist.

To keep the concrete moist, you can cover it with plastic wrap or burlap. You can also spray the concrete with water several times a day.
