How to Build an Outdoor Fireplace with Cinder Blocks

Building an outdoor fireplace with cinder blocks is a relatively simple and inexpensive project that can be completed in a weekend. With a little planning and preparation, you can create a beautiful and functional addition to your backyard that will provide years of enjoyment.

Materials you'll need:

* Cinder blocks * Mortar * Gravel * Sand * Rebar * Fire bricks * Concrete cap * Chimney flue * Chimney cap * Grout * Masonry sealer

Tools you'll need:

* Level * Trowel * Hammer * Chisel * Wheelbarrow * Mixer * Safety glasses * Gloves

Instructions:

1. Choose a location: The first step is to choose a location for your fireplace. The ideal location is on a level surface, away from any trees or structures that could be damaged by the heat. Once you have chosen a location, clear the area of any debris.

2. Prepare the base: Excavate a hole for the base of the fireplace that is 2 feet deep and 3 feet wide. Fill the hole with gravel and tamp it down to create a solid base.

3. Build the firebox: Start by laying out the first course of cinder blocks around the perimeter of the firebox. Use a level to make sure that the blocks are level. Apply a layer of mortar to the top of the blocks and lay the second course of blocks on top. Continue building the firebox until it is the desired height.

4. Install the fire bricks: Line the inside of the firebox with fire bricks. Fire bricks are more resistant to heat than cinder blocks and will help to protect the firebox from damage.

5. Build the chimney: Build the chimney by stacking cinder blocks on top of the firebox. Use a level to make sure that the blocks are level and plumb. Install a chimney flue and chimney cap at the top of the chimney.

6. Pour the concrete cap: Mix a batch of concrete and pour it over the top of the chimney. The concrete cap will help to protect the chimney from the elements.

7. Grout the fireplace: Once the concrete cap has cured, grout the joints between the cinder blocks. Grouting the joints will help to seal the fireplace and prevent water from getting inside.

8. Apply masonry sealer: Apply a coat of masonry sealer to the entire fireplace. Masonry sealer will help to protect the fireplace from the elements and make it more durable.
