What You'll Learn
Cleaning the brick
Painting the inside brick of a fireplace can be a great way to give your space a new look with relatively little effort. However, before you start painting, it is essential to clean the brick surface thoroughly. Here is a step-by-step guide to help you through the process:
Step 1: Remove Debris
Start by using a stiff wire brush to brush away any loose debris, paying special attention to the mortar lines between the bricks. This step ensures that you have a smooth and even surface to work with.
Step 2: Vacuum
After brushing, use a vacuum, preferably with a brush attachment, to carefully remove all the dust from the surface and floor. This step is crucial to prevent dust particles from interfering with the painting process and to ensure your safety by avoiding the inhalation of dust.
Step 3: Deep Clean
Now, it's time to give the bricks a deep clean to remove any accumulated soot, dirt, or mineral residue. You can use a variety of cleaning solutions for this step:
- Soap and Water: Create a solution of mild soap and water and apply it to the bricks with a sponge. Then, rinse with clean water. This method is gentle yet effective and is a good starting point if you're unsure about the stubbornness of the soot.
- Vinegar and Water: Vinegar is an excellent natural alternative to soap. Its acidity helps break up the grime on the bricks.
- Baking Soda and Dish Soap: Make a paste of baking soda and dish soap and apply it to the bricks with a toothbrush or grout brush. This method is useful for removing deep-set soot. Finish with a dish soap rinse.
- Commercial Cleaners: You can also opt for commercial cleaners like Insl-X® All-Purpose Citrus Cleaner, Simple Green, or Trisodium Phosphate (TSP) for a deeper clean. Always remember to spot-test these cleaners on a small area first to ensure they don't cause discolouration.
Step 4: Rinse and Dry
After cleaning, gently rinse the bricks with water and use a towel to dry off any excess water on the surface. Allow the bricks ample time to air dry completely. You can speed up the drying process by directing a fan towards the fireplace.
Step 5: Spot Treat Stains
Once the bricks are dry, you may notice some remaining stains. Use your chosen cleaning chemical to spot-treat these stains, following the same procedure as before.
Step 6: Prime the Bricks
Before painting, it is essential to prime the bricks, especially if you want to prevent soot or mineral staining from leaching through the paint. Use a high-quality acrylic latex primer, such as Fresh Start® High-Hiding All-Purpose Primer or Insl-X® Aqua Lock®. Apply the primer to the mortar lines between the bricks and then to the face of the brick fireplace using a roller. Let the primer dry overnight.
Remember, bricks are porous and absorbent, so they may require more primer than a standard wall surface. Additionally, always wear personal protective equipment (PPE), including gloves and goggles, when working with any cleaning solutions.

Choosing the right paint
Painting a brick fireplace is a great way to upgrade your living space and give it a fresh, modern look. It is a simple and affordable way to dramatically change the look of your living area without undergoing a renovation. However, choosing the right paint is crucial for the appearance and longevity of your painted fireplace. The wrong paint may peel, chip, or simply not adhere to the surface, leading to frustration and additional costs.
Firstly, it is important to note that the paint you choose should be designed for brick surfaces. While painting a brick fireplace, you will need to use a heat-resistant paint that is specifically made to withstand the higher temperatures of the firebox. If you use regular paint, it will likely burn off, potentially releasing hazardous fumes into your home. Look for paints formulated specifically for masonry or brick surfaces, as these will adhere better and last longer.
Secondly, when it comes to the type of paint, acrylic latex paint is generally the best choice for brick fireplaces. It is durable, easy to clean, and allows the brick to breathe, which helps prevent moisture issues. A high-quality acrylic latex primer, such as Fresh Start® High-Hiding All-Purpose Primer or Insl-X® Aqua Lock®, is also recommended.
Thirdly, consider the colour of the paint. While white is the most popular colour for painting brick fireplaces, you can choose any colour that complements your existing decor and the overall style you want to achieve. Light colours can brighten a room and make it feel larger, while darker hues can create a cosy and intimate atmosphere.
Finally, the paint sheen is another important consideration. A Satin, Semi-Gloss or Gloss sheen is recommended as they are easier to clean than duller sheens. These sheens can also be cleaned without the worry of damaging the brick from moisture absorbed from cleaning, humidity, or dampness, which can cause the brick to crumble over time.

Priming the brick
Painting a brick fireplace can be a great way to update the look of your space. However, it is important to prime the brick properly to ensure a smooth and long-lasting finish. Here is a step-by-step guide to priming the brick:
Clean the Brick Surface:
Before priming, it is essential to clean the brick surface thoroughly. Use a stiff wire brush to remove any loose debris, paying special attention to the mortar lines between the bricks. This ensures that the paint will adhere properly to the brick. You can also use soapy water or a brick cleaner to remove any accumulated soot or mineral residue. Be sure to spot-test the cleaner on a small area first to ensure it doesn't cause discolouration.
Tape Off Edges and Protect Surroundings:
Before priming, use painter's tape to tape off any edges, trim, or areas you do not plan to paint. This will help create crisp lines and protect surrounding areas from primer and paint. Additionally, lay down drop cloths or moving blankets to protect the floor and any furniture.
Choose the Right Primer:
Selecting an appropriate primer is crucial for a successful paint job. Look for primers specifically designed for brick and masonry, such as Kilz 2 All-Purpose Interior and Exterior Primer or Sherwin-Williams Loxon Masonry Primer. These primers are thinner, allowing them to penetrate the brick's porous surface effectively. A high-quality acrylic latex primer, such as Fresh Start® High-Hiding All-Purpose Primer, is also recommended.
Apply the Primer:
Use a paintbrush to prime all the mortar lines between the bricks, ensuring no spots are missed. Then, use a roller with an appropriate nap thickness (such as 1/2 inch or 3/8 inch, depending on brick texture) to prime the face of the brick fireplace. A thicker nap roller is generally recommended for better paint hold and coverage. If using a light paint colour, consider applying a second coat of primer to prevent any soot or mineral staining from showing through.
Allow Primer to Dry:
Let the primer dry completely before proceeding to painting. The drying time may vary depending on the product, but generally, it is recommended to let it dry overnight or for at least 3 to 4 hours. Some primers may require longer drying times, such as 24 hours, to ensure the brick is entirely dry.
By following these steps, you will effectively prime the brick of your fireplace, creating a solid foundation for your chosen paint colour. Remember, proper preparation and priming are key to achieving a professional and long-lasting finish.

Painting the mortar lines
First, use the wire brush to scrub the mortar lines between the bricks. This will help to remove any loose debris and ensure that the mortar is in good condition. Pay close attention to the mortar lines, as they can accumulate dirt and debris. Once you have brushed away the loose debris, use a vacuum to remove any remaining dust from the surface and the surrounding floor area.
Next, it is important to deep clean the mortar lines to remove any accumulated soot or mineral residue. This step will prevent the soot or residue from affecting the primer and topcoat. You can use a trisodium phosphate (TSP) solution, diluted with water, and applied with a sponge. Alternatively, you can use a powerful cleaner or degreaser, followed by a rinse with clean water. Always test the cleaner on a small, inconspicuous area first to check for any discolouration.
After the mortar lines are clean and dry, you can begin priming. Use a paintbrush to carefully apply a high-quality primer to the mortar lines, making sure not to leave any spots unprimed. A high-quality acrylic latex primer, such as Fresh Start® High-Hiding All-Purpose Primer or Insl-X® Aqua Lock®, is recommended. Allow the primer to dry completely before moving on to the next step.
Once the primer is dry, you can start painting. Use a small brush to carefully paint the mortar lines, ensuring that you don't miss any spots. After the mortar lines are painted, you can use a roller to apply paint to the face of the bricks, working in small sections to ensure even coverage. Allow the first coat of paint to dry completely before deciding if a second coat is necessary. Most brick fireplaces will require at least two coats of paint for full coverage.

Painting the brick
To paint the brick inside your fireplace, start by thoroughly cleaning the surface to ensure your paint adheres and dries properly. Use a wire brush to scrub the brick surface and mortar joints, loosening dirt, soot, or crumbling mortar. Pay special attention to the mortar lines to remove any loose debris. Once you've cleared all accessible debris, use a shop vacuum to remove dust on and around the fireplace. Then, deep-clean the brick to remove any remaining soot, mineral residue, or oils, which can affect the primer and topcoat. You can use a solution of trisodium phosphate (TSP) or a mixture of soap and water.
After cleaning, tape off the edges of your fireplace and trim. Then, use a paintbrush to prime all the mortar lines and any other cracks or crevices. It is important to use a high-quality primer, as brick and mortar are porous and can absorb paint unevenly. A good primer seals the fireplace's surface, creating a uniform base for the paint and helping the paint adhere better. You can use a high-quality acrylic latex primer or a concrete and masonry primer. Once the mortar is primed, use a roller to prime the face of the brick fireplace. Allow the primer to dry fully overnight.
Once the primer is dry, you can begin painting. Start by using a brush to apply paint to the mortar lines and any other cracks. Then, use a roller to apply paint to the rest of the brick surface, ensuring that you are applying the paint evenly. You will need to use a heat-resistant paint that is specifically made to withstand the high temperatures of the firebox. Look for paints formulated for masonry or brick surfaces, as these will adhere better and last longer.
With the right prep work and products, painting the brick inside your fireplace is a great way to give your space a refresh without a full renovation.
