Clean the bricks with a wire brush
Painting a brick fireplace is a great way to refresh your space without a full renovation. Before you begin painting, it's important to properly clean the bricks to ensure the paint adheres well and that your fireplace has a long-lasting finish. Here's a detailed guide on how to clean your bricks with a wire brush:
Start by using a stiff wire brush to thoroughly brush the bricks and mortar. Pay special attention to the mortar lines between the bricks, ensuring you remove any loose debris or material. This step is crucial as it prepares the surface for painting and helps create a smooth base. Take your time with this process, as a clean surface is essential for any painting project.
After brushing, carefully inspect the mortar. Ensure it doesn't require any repairs before you begin painting. This inspection is important because you want to ensure the structural integrity of your fireplace before proceeding. If you notice any issues, be sure to address them before moving on to the next step.
Once you've brushed and inspected the bricks, it's time to remove the dust from the surface and the surrounding floor. Use a vacuum, preferably with a brush attachment, to carefully collect any remaining dust particles. This step ensures that the area is ready for the next stage of cleaning and helps create a clean workspace. Remember to always wear personal protective equipment (PPE) when working to avoid breathing in dust and protecting your eyes from particles.
After vacuuming, proceed to deep clean the bricks. This step ensures the removal of any accumulated soot or mineral residue that could affect the paint's adhesion and appearance. You can use a biodegradable, phosphate-free cleaner diluted with water, or a simple solution of warm water and soap. Apply the cleaner to the bricks with a sponge, then rinse with a clean sponge and fresh water. If any stubborn residue remains, you can use a degreaser or trisodium phosphate for a deeper clean.
Allow the bricks to dry completely before moving on to the next steps of priming and painting. Bricks are porous and absorb water, so a full 24 hours of drying time is recommended. By following these steps, you'll ensure that your bricks are properly cleaned and prepared for a fresh coat of paint.

Remove dust and debris with a vacuum
Before painting a brick fireplace, it is important to clean the surface thoroughly. This will ensure that the paint adheres well and that there is no dirt or debris that could cause the paint to chip or peel later on.
First, use a stiff wire brush to clean the brick and mortar, paying special attention to the mortar lines and removing any loose debris. If there are any sharp areas, you can use a hand file to smooth them out, but be cautious if the brick is old as it may be brittle.
Once the brushing is complete, it is time to remove the dust and debris with a vacuum. Use a shop vacuum to carefully remove all dust from the surface and the surrounding floor. It is recommended to use a vacuum with a brush attachment or a brush to gently remove the dust. This step is crucial to ensure that no dust or debris remains on the surface before painting.
After vacuuming, you may want to consider using a cleaner or degreaser to give the bricks a deep clean and remove any remaining soot or mineral residue. Bricks are porous and absorb water, so be sure to dilute the cleaner according to the instructions and do a spot test first to ensure it doesn't cause discolouration. Allow the bricks to dry completely before moving on to priming and painting.
Remember to always wear personal protective equipment (PPE) when working on projects like this to avoid breathing in dust or getting particles in your eyes.

Deep clean the bricks with a sponge
Before painting a brick fireplace, it is important to clean the bricks thoroughly. This will ensure that the paint adheres well and that there is no dirt or residue that could affect the final finish.
First, use a stiff wire brush to brush away any loose debris, paying special attention to the mortar lines between the bricks. This will ensure that there is no loose material that could come away once you start painting. Once you have brushed away all the debris, use a vacuum with a brush attachment to remove any remaining dust from the surface and floor. It is important to wear personal protective equipment (PPE) during this process to avoid breathing in any dust.
The next step is to deep clean the bricks with a sponge. Mix a solution of warm water and soap or a mild degreaser, such as Insl-X® All-Purpose Citrus Cleaner. Before applying the solution to the bricks, test a small amount in an inconspicuous area to ensure that it does not cause any discolouration. Apply the solution to the bricks using a sponge, rubbing it thoroughly into the brick surface. Pay particular attention to any areas with accumulated soot or mineral residue, as these could affect the final finish.
Once you have applied the cleaning solution, use a clean sponge and fresh water to wipe away any remaining soap or cleaner. Be sure to rinse the bricks thoroughly and remove any remaining residue. If any soot or residue remains, you may need to use a stronger degreaser or trisodium phosphate for a deeper clean. Bricks are porous and will absorb a lot of water, so allow them to dry thoroughly for at least 24 hours before moving on to the next step.

Apply primer to the bricks
Before applying primer to the bricks, ensure that the fireplace is clean and free of any loose debris. Use a stiff wire brush to clean the mortar lines and brick surface, removing any loose material. It is important to pay special attention to the mortar lines and inspect them for any necessary repairs before priming and painting. Once the brushing is complete, use a vacuum with a brush attachment to remove dust from the surface and the surrounding floor area.
After the fireplace is thoroughly cleaned, it is time to apply the primer. Use painter's tape to mask off any areas that you do not want to be primed or painted. For the primer itself, a product like Sherwin-Williams' Concrete and Masonry Primer is recommended. Use a 1" flat, stiff-bristle brush to apply the primer to the mortar lines and any cracks or crevices. Then, use a mini roller to cover the remaining brick surface, ensuring that the primer is applied as evenly as possible. Allow the primer to dry completely before moving on to painting.
Primer plays a crucial role in the painting process, especially when painting a brick fireplace. Using a quality primer ensures that the topcoat adheres well to the brick surface and helps to hide darker colours, like red brick, under the final coat of paint. A properly applied primer will also provide alkali and efflorescence resistance for masonry surfaces.
It is important to note that bricks are porous and absorb a lot of water, so it is recommended to allow the bricks to dry for at least 24 hours before priming and painting. This will ensure that the primer and paint adhere properly and that your paint job lasts.

Paint the bricks with a roller
Painting a brick fireplace is a great way to refresh your space without a full renovation. It is important to prepare the surface before painting to ensure the best results. Start by using a stiff wire brush to clean the bricks, paying special attention to the mortar lines to remove any loose debris. You should then assess the mortar to ensure it does not need any repairs before you begin painting. Once the brushing is complete, use a vacuum with a brush attachment to carefully remove all dust from the surface and floor. You can also use a damp cloth to wipe down the bricks and remove any remaining dust.
Before painting, it is essential to deep clean the brick to remove any accumulated soot or other mineral residue that could affect the primer and topcoat. Try a biodegradable, phosphate-free cleaner like Insl-X® All-Purpose Citrus Cleaner, or a solution of soap and water. Be sure to do a spot test first in an inconspicuous area to check for discoloration. To wash the bricks, thoroughly rub the cleaner into the entire brick surface with a sponge, then wipe it with a clean sponge and fresh water. If any soot or residue remains, a degreaser or trisodium phosphate can be used for a deeper clean. Allow the bricks to dry for at least 24 hours before priming and painting, as bricks are porous and absorb a lot of water.
Once the brick fireplace is primed and dry, you can begin painting. It is recommended to use a roller with a thick-nap roller cover (1/2 inch or 3/8 inch) for best results. Start by carefully painting all the mortar lines with a brush before using the roller to apply paint to the face of the bricks. If your fireplace is floor-to-ceiling, use an extension pole to reach the higher areas. Work in sections, ensuring that you are applying the paint evenly.
A second coat of paint is recommended to ensure a long-lasting and consistent finish. Assess the fireplace after the first coat has dried, and apply a final coat if needed. If you have built-in bookcases or baseboards connected to the mantel, use the same colour for a consistent look. A bold colour can create a focal point in the room, while a lighter colour can help to brighten the space and make the fireplace blend seamlessly into a white wall.

Frequently asked questions
Painting a brick fireplace is a great way to refresh your space without a full renovation. First, ensure you have the right tools, including safety goggles, gloves, a wire brush, a sponge, painter's tape, a paintbrush, and a paint roller with a thick-nap roller cover. Then follow these steps:
- Clean the bricks with a wire brush to remove any loose debris, paying special attention to the mortar lines.
- Deep clean the bricks with a sponge and a cleaning solution to remove any soot or mineral residue.
- Apply a primer to the bricks and let it dry.
- Paint the mortar lines with a brush, then use a roller to paint the bricks.
- Apply a second coat of paint if needed.
It is important to use a premium paint designed for high temperatures and adhesion to brick. Sherwin-Williams ProClassic® Waterborne Interior Acrylic Enamel is a recommended option. You will also need a quality primer to ensure the paint adheres well and to prevent discolouration from brick showing through.
The colour you choose will depend on the look you want to achieve. If you want a bright, airy feel, choose a light colour like white. If you want a bold statement, go for a darker or brighter colour. You could also try a layered look with a brick-coloured base coat and a lighter or darker glaze to create a natural brick variation.
While it is possible to use an angle grinder to smooth out the bricks, this can ruin the brick and cause spalling. A safer option is to use a thin-set or floor-levelling cement to create a smooth concrete finish.
Allow the bricks to dry for at least 24 hours after cleaning before applying primer and paint. After painting, leave the fireplace to dry overnight or for at least 24 hours before using it or building a fire.
