How to Build an Outdoor Fireplace Out of a Cinder Block Wall

An outdoor fireplace is a great way to add warmth and ambiance to your backyard. It's also a perfect spot to gather with friends and family on a cool night. If you're thinking about building an outdoor fireplace, a cinder block wall is a great option. Cinder blocks are relatively inexpensive, easy to work with, and fire-resistant. Plus, they can be used to create a variety of different looks.

Materials You'll Need

To build an outdoor fireplace out of a cinder block wall, you'll need the following materials:

Cinder blocks
Mortar
Firebrick
Fireplace grate
Concrete reinforcing wire
Concrete mix
Gravel
Sand
Water

Building the Wall

The first step is to build the wall. To do this, start by laying out the cinder blocks in a dry run to determine the size and shape of the fireplace. Once you're happy with the layout, you can start laying the blocks with mortar. Be sure to stagger the blocks as you lay them to create a stronger wall. As you build the wall, you'll need to insert concrete reinforcing wire every few courses to help hold the wall together.

Creating the Firebox

Once the wall is built, you can start creating the firebox. To do this, line the inside of the fireplace with firebrick. Be sure to leave a space between the firebrick and the cinder block wall to allow for expansion. Once the firebox is lined, you can install the fireplace grate.

Finishing the Fireplace

The final step is to finish the fireplace. You can do this by applying a layer of stucco or masonry paint to the outside of the wall. You can also add a mantel or other decorative elements to complete the look.

Tips for Building an Outdoor Fireplace

Be sure to use a level to make sure that the wall is level as you build it.
Allow the mortar to dry completely before using the fireplace.
Never leave a fire unattended.
Be sure to clean the fireplace regularly to prevent buildup of soot and debris.

Conclusion

Building an outdoor fireplace out of a cinder block wall is a relatively easy and inexpensive project that can add a lot of value to your backyard. With a little planning and preparation, you can create a beautiful and functional fireplace that will be enjoyed by your family and friends for years to come.
