How To Build A Cinder Block Outdoor Fireplace

Building an outdoor fireplace is a great way to enjoy your backyard space and create a cozy gathering spot for friends and family. Using cinder blocks for the construction is a cost-effective and durable option that can be completed in a weekend.

In this article, we will discuss the essential aspects of building a cinder block outdoor fireplace. We will cover everything from choosing the right materials to laying the blocks and adding the finishing touches.

Choosing the Right Materials

The first step in building a cinder block outdoor fireplace is to choose the right materials. You will need the following:

Cinder blocks
Mortar
Firebricks
Gravel
Rebar

Cinder blocks are made from concrete and are available in a variety of sizes. For an outdoor fireplace, you will want to use blocks that are at least 4 inches thick. Mortar is used to bind the blocks together. Firebricks are used to line the firebox and protect it from the heat. Gravel is used to create a base for the fireplace. Rebar is used to reinforce the fireplace.

Laying the Blocks

Once you have chosen your materials, you can begin laying the blocks. Start by laying out the blocks in a dry fit to determine the best arrangement. Once you have the blocks arranged, you can begin mortaring them together. Be sure to use a level to ensure that the blocks are level and plumb.

To mortar the blocks, apply a bead of mortar to the edge of one block and then place another block on top of it. Use a trowel to spread the mortar evenly and remove any excess. Continue mortaring the blocks together until the fireplace is complete.

Adding the Finishing Touches

Once the fireplace is complete, you can add the finishing touches. This could include adding a mantel, a hearth, or a chimney. You can also paint or stain the fireplace to match your décor.

Building a cinder block outdoor fireplace is a relatively easy project that can be completed in a weekend. By following these essential aspects, you can create a beautiful and functional fireplace that will be enjoyed for years to come.
