  • Black high-heat paint

Step 2: Protect The Working Area

It is always wise to protect yourself and the space you are working in before any dirty job, such as painting a fireplace. Move furniture and carpets away from the fireplace, put gloves on your hands and protective glasses on your eyes. It is also recommended to protect the mouth and nose with a mask.

Step 3: Clean And Prep the Firebox

In order to paint the interior of the fireplace successfully, you must clean and prepare it thoroughly. The first step is to clean all the remains of ash, even the smallest ones. Pick up a metal brush and trisodium phosphate if you can’t do the job well with just a broom and rags.

When all the remains have been removed, wash the fireplace well, wipe it and let it air dry. Note, do not start cleaning the fireplace for at least three hours after you put out the last fire.

Step 4: Mix The Paint

If you plan to apply a primer to the surface, first prepare it with the help of a paint mixer. Remember that the paint you choose must withstand high temperatures that can reach up to 1,200°F.

After the primer dries, you can mix the paint that you have chosen for the final layer. Always match the tone of the primer and main paint color so that your fireplace looks exactly as you imagined.

Step 5: Use A Brush

Considering that the fireplace’s interior is not a surface that is exposed to views from a short distance in any situation, you do not have to bother buying expensive brushes with smooth surfaces. An ordinary nylon brush is enough for this job.

Keep in mind that when you paint with a brush, you can expect a lot of paint dripping. Therefore, cover the floor with old newspapers or cardboard that will absorb them.

Have a wet sponge or an old cloth ready so that when paint ends up somewhere, it shouldn’t, you can clean it fast. If you don’t remove the paint drip immediately, it will be more difficult later.

Step 6: Let The Paint Dry

Although it doesn’t seem like it at first glance, a thinner layer of paint will protect the interior of a fireplace better than a thicker one, so don’t overdo it. One layer of paint is enough. Why? If you apply the paint in a thick layer, it may crack over time under the influence of high temperature.

Even though it is resistant to direct fire heat, two or more layers of this paint are applied only when you paint the metal parts of the fireplace or when you paint the fireplace for the first time after it has been built.

Note! Don’t use the fireplace for at least a few hours before you start working on this project.
