Preparing Brick Surfaces for Painting

Before you start painting brick, you need to thoroughly clean and prepare the surface.

First, remove any loose mortar or debris with a wire brush. Scrub away built-up dirt and grime with a detergent and scrub brush, then rinse well with water.

Let the brick dry completely. This usually takes 3-7 days. Moisture trapped behind the paint will cause bubbling and peeling.

Next, fill any cracks or holes in the mortar joints with caulk, spackle, or weather-resistant filler. Smooth the area with fine-grit sandpaper.

If the brick has a glossy sealant or is stained, you’ll need to rough up the surface so the paint has something to grip onto. Lightly sand the entire wall with 80-120 grit sandpaper. Wipe away dust with a tack cloth.

For the best results, apply a primer designed for masonry. Primer helps the topcoat of paint adhere better and provides an even base layer. Roll or brush the primer on and let it dry as directed.

Finally, you’re ready for paint! For brick, use an acrylic latex or elastomeric paint. These provide the flexibility needed as brick expands and contracts. Apply at least two coats, waiting for each to dry in between.

With the proper prep, your brick will be ready to transform into any color you desire. Take your time—the results will be well worth the effort. If done right, a coat of paint can revive old brick and give your home an entirely new look.

Paint Options for Brick Surfaces

When it comes to paint options for brick, you have a few good choices.

Latex or acrylic paint

This is a popular and inexpensive option for painting brick. Latex or acrylic paint provides good coverage and adhesion. It’s also water-based, so it’s easy to clean up. You’ll want to choose a paint specifically intended for masonry or brick.

Oil-based paint

Oil-based paint is another choice and provides good coverage. However, it has strong fumes, takes longer to dry, and requires the use of solvents for cleanup. Oil-based paint may also darken brick. Use only in well-ventilated areas.

Elastomeric paint

For brick that's exposed to a lot of moisture or weather, elastomeric paint is a good option. It contains elastic polymers that allow it to stretch and flex with the brick. This helps prevent cracking. Elastomeric paint provides a waterproof coating. It is more expensive but provides the best protection.

Stain

If you want to change the color of brick but still show its texture, consider stain. Stain soaks into the surface of the brick rather than coating it. Transparent stains will subtly tint the brick while still allowing the surface texture and details to show through. Stain requires a protective clear topcoat to seal it.

Masonry primer

For the best results, apply a masonry primer before the topcoat of your choice. A primer helps the paint better adhere to the brick surface. It also provides a uniform base coat so your final coat of paint looks even and professional.

With the right preparation and choice of paint, you'll have your brick looking fresh and new again. Take your time to do it right and you'll enjoy the results for years to come.

Painting Techniques for Brick

Once you’ve properly prepped the brick surface, it’s time to apply your paint. There are a few techniques that will help you get the best results.

Rolling

For large, flat areas of brick, a roller is your best tool. Use a 3/8-inch nap roller cover and work in sections. Load the roller with paint and roll it onto the brick using vertical strokes. Then use horizontal strokes to smooth it out. Work slowly to avoid drips and uneven coverage. Let each section dry before moving on.

Brushing

For corners, edges, and trim, use an angled brush. Load the brush with paint and dab it onto the brick using light, even pressure. Drag the brush slowly along edges and seams. Work in short sections, cleaning and reloading the brush as needed. Brushing takes more time but gives you more control and the best results for intricate areas.

Spraying

If speed and convenience are priorities, consider using an airless sprayer or paint sprayer to apply a base coat. Spraying paint onto brick provides even coverage quickly. However, it can be messy and difficult to control. You’ll still need to backbrush or roll to properly cover the surface and provide an even coat. Spraying works best when combined with another technique.

Distressing (optional)

For a rustic look, you may want to distress your newly painted brick. Once the paint is dry, use sandpaper, wire brushes, or abrasive pads to wear away some of the paint and expose the brick underneath. Focus on edges, corners and areas that would naturally show signs of wear and tear. Wipe away dust with a tack cloth and apply a clear sealer to protect the finish.

With the right technique (or combination of techniques) and a careful, methodical approach, you’ll be well on your way to transforming your brick surface with a fresh coat of paint. Take your time—patience and precision will pay off!

Cleaning and Repairing Brick Before Painting

Before painting brick, proper cleaning and repair is essential. Cleaning brick removes dirt and debris, opens up the surface, and provides “tooth” for the paint to adhere to. Repairing any cracks or damage in the brick will help ensure an even coat of paint that lasts.

Cleaning Brick

The first step is to scrub the brick with a degreaser or heavy-duty cleaner to remove any oils or grime. Then, use a pressure washer to blast away any loose particles. For stuck-on messes, scrub with an abrasive sponge or scrubber. Rinse thoroughly with water to remove all cleaning solutions.

Let the brick dry completely, at least 24 to 48 hours. Moisture trapped behind the paint can cause issues down the road.

Filling Cracks and Holes

Inspect the brick for any cracks, holes or damage and fill them in. Use a concrete filler or brick mortar that matches your brick color as closely as possible. For small cracks, a caulk may work. Scrub off any excess filler with a putty knife and sand down rough edges. Let all fillers dry as directed before painting.

Priming

For the best results, especially when painting contrasting colors, apply a primer. An acrylic latex or oil-based primer works well for brick. Apply two coats, waiting 2 to 4 hours between coats. Let the primer dry for at least 24 hours before painting. Priming helps provide a uniform surface for the paint to adhere to and maximizes coverage.

Paint Options

Latex or acrylic paints are a good choice for brick because they “breathe” and have built-in flexibility. Avoid enamel paints which can lead to chipping and peeling. For darker colors, use a paint formulated for exteriors or with a primer included. Stain-blocking paint may be needed if painting over a stained brick. In all cases, check the manufacturer’s recommendations for suitable surfaces.

With the proper prep, your brick will provide the perfect blank canvas. Careful cleaning, filling in any damage, and priming if needed, ensure a professional finish. Choosing a high-quality, breathable paint formulated for exteriors results in a durable finish that will make your brick surface look brand new.

Priming Brick Surfaces

Proper preparation is key to a long-lasting, attractive finish on brick. Priming the surface before painting ensures the paint adheres well and looks professional.

Cleaning Brick

Start by cleaning the brick thoroughly. Use a stiff brush to remove loose particles and dust. For stubborn grime, mix one part bleach with three parts water and scrub with a brush. Rinse the surface thoroughly with a hose and let the brick dry completely before priming.

Filling Cracks and Holes

Inspect the brick for cracks, holes, or imperfections. Fill them with a concrete patch compound or brick caulk, smoothing with a putty knife. Allow the filler to dry as directed before priming.

Choosing a Primer

Use an alkali-resistant primer formulated for masonry surfaces. These primers are designed to bond with the salts and minerals in brick. Acrylic latex, epoxy, or masonry-specific primers are all good options. For best adhesion, choose a product labeled for brick.

Applying the Primer

After cleaning and filling, apply primer with a brush to reach cracks and crevices, then roll larger areas. Apply at least two coats, waiting 2 to 4 hours between each. Ensure full coverage, and let the final coat dry for at least 24 hours before painting.

With the right cleaning, filling, and primer, you’ll create a smooth, durable base for paint that delivers professional results.

Top Paint Colors for Brick

Once the surface is clean and primed, you can choose from a wide range of paint colors. For brick, select high-quality paints formulated for masonry to achieve lasting beauty.

Priming the Surface

Begin by scrubbing away dirt with a wire brush. Apply a masonry-specific primer such as acrylic brick primer or primer sealer. Two coats, with 2 to 4 hours of drying between, give the best results.

Selecting Paint

Acrylic latex or acrylic enamel paints provide excellent coverage and durability. Flat or satin finishes often work best. Avoid oil-based paints, which tend to chip. Popular color choices for brick include:

• Warm reds, browns, and terra cottas
• Cool grays, blues, and greens
• Creamy off-whites or ivories

Application Technique

Cut in around mortar lines and edges with a brush first, then use a 3/8-inch nap roller for larger areas. Apply at least two coats, extending each coat 6 to 8 inches beyond the previous section. Wait 2 to 4 hours between coats. This method ensures smooth, even coverage.

With the right technique, even DIYers can achieve a polished, professional finish on brick walls, fireplaces, and other masonry features.

Painting Interior vs. Exterior Brick

Painting interior and exterior brick requires slightly different approaches. Interior brick is protected from the elements, while exterior brick faces weather and temperature changes.

Interior Brick

Clean interior brick by vacuuming dust and scrubbing greasy spots with a degreaser. Rinse thoroughly and let dry. Prime the brick for best coverage, especially when changing from dark to light colors. Use interior acrylic or latex paint with an eggshell or satin sheen. Apply at least two coats, brushing edges first and rolling the rest.

Exterior Brick

Exterior brick requires more prep. Power wash to remove dirt, scrub mold or mildew, and repair cracks. Allow 1 to 2 days for drying. Choose an exterior acrylic latex paint with a satin or glossy finish for better protection. Apply primer first, then at least two coats of paint, waiting 4 to 6 hours between coats. Paint only in temperatures between 50°F and 90°F with humidity below 85%, and avoid rainy conditions.

Exterior paint may take up to a month to fully cure, so treat surfaces gently during this period.

Common Painting Mistakes to Avoid

To achieve the best results, avoid these common pitfalls:

Inadequate Preparation

Always clean thoroughly and repair cracks before painting. Skipping this step can result in uneven coverage and a blotchy finish.

Choosing the Wrong Paint

Use high-quality acrylic latex or elastomeric paint. Avoid standard wall paints, which won’t adhere properly to brick.

Applying Too Much Paint at Once

Apply two or three thin coats instead of one thick coat. Thick coats are prone to drips and peeling, while thin coats bond better and produce a smoother finish.

Not Letting Coats Dry Completely

Follow the drying times listed on your paint can. Rushing coats can lead to blistering or peeling.

Not Priming First

Primer improves adhesion and coverage, helping you achieve a professional finish with fewer coats.

Not Protecting Trim

Mask off trim, windows, and doors to avoid splatters. Remove tape before the paint dries to prevent peeling.

Taking your time and avoiding these mistakes will help you achieve a high-quality, long-lasting paint job.
