Why Paint Your Outdoor Bricks?
Painting outdoor brick isn’t just about aesthetics, though a beautiful change can certainly be transformative! It’s also a practical decision that can offer a protective layer against the elements. Bricks, especially older ones, can be porous and absorb moisture. This can lead to issues like freeze-thaw damage in colder climates, where absorbed water freezes, expands, and can cause bricks to crack and crumble.
A good quality paint can create a barrier, helping to repel water and shield your bricks from harsh sun, rain, and wind. It’s a way to refresh the look of your home, update outdated colors, or even create a cohesive design among different exterior materials. Plus, it’s a more budget-friendly alternative to replacing brickwork that might just need a cosmetic facelift.
Choosing the Right Paint for Bricks
This is where we lay the foundation for a successful project! Not all paints are created equal, and using the wrong type on brick can lead to peeling, bubbling, and a host of other problems down the line. For outdoor brick, we need something that can breathe and withstand the elements.
Best Types of Paint for Exterior Brick
When you’re looking for paint for bricks outdoor, you’ll want to prioritize breathability and durability. This means looking for paints that allow moisture vapor to escape from the brick. If moisture gets trapped, it can cause the paint to fail, and worse, damage the brick itself.
100% Acrylic Latex Paint: This is often the top recommendation for painting exterior brick. It’s water-based, flexible, and breathable. It adheres well to masonry surfaces and holds up nicely against UV rays and weathering. Look specifically for formulas designed for exterior use on masonry or stucco.
Mineral-Based Paints (Silicate Paints): These paints chemically bond with masonry surfaces, becoming part of the brick itself. They are incredibly durable, breathable, and eco-friendly. They offer a natural, matte finish and are known for their longevity. While they can be more expensive upfront, their lifespan often makes them a cost-effective choice in the long run. Some examples include silicate or lime wash paints.
Masonry Stain: If you love the natural look of brick but want to change its color or even it out, masonry stain is a great option. It penetrates the brick rather than forming a film on top. This preserves the texture and breathability of the brick. Stains come in various opacities, from transparent to semi-transparent and solid.
Paints to Avoid
Oil-Based Paints: These can trap moisture in the brick, leading to peeling and flaking. They are less flexible and can crack as temperatures change.
Flat House Paints (non-masonry specific): Standard flat paints might not have the breathability or adhesion properties needed for brick, which is a very porous surface.
Understanding Breathability: The Key to Lasting Paint
We’ve mentioned “breathability” a few times, and it’s worth diving a little deeper into why it’s so crucial for brick. Bricks are porous, meaning they have tiny holes that allow air and moisture vapor to pass through. This is a natural characteristic that helps the brick “breathe.”
When you paint a surface, you’re essentially creating a coating. If this coating isn’t breathable, it acts like a barrier. Any moisture that gets into the brick from the sides or from underneath (wicking up from the ground) can’t evaporate outward through the paint. This trapped moisture builds up pressure. Eventually, this pressure forces the paint to blister, peel, or crack. In winter, this trapped moisture can freeze and expand, causing physical damage to the brick itself.
So, when choosing paint for bricks outdoor, always check the label for terms like “breathable,” “vapor-permeable,” or specifically mention suitability for masonry. 100% acrylic latex and mineral-based paints are generally excellent choices because they allow this necessary vapor exchange.
Essential Tools and Supplies
Before we grab our brushes, let’s gather everything we’ll need. Having all your supplies ready makes the painting process smooth and enjoyable.
Tools for Preparation
Stiff-bristled Brush or Push Broom: For sweeping away loose debris and dirt.
Wire Brush: To scrub away stubborn grime, efflorescence (white powdery deposits), or flaking paint.
Garden Hose with Spray Nozzle: For rinsing the bricks.
Pressure Washer (Optional, use with caution): Can speed up cleaning but use a low setting to avoid damaging mortar or brick. Always test in an inconspicuous area first.
Bucket: For cleaning solutions and water.
Scraper or Paint Chisel: To remove any old, peeling paint if you’re painting over a previously painted surface.
Caulking Gun with Exterior Caulk: To fill cracks and gaps.
Putty Knife: For applying caulk and smoothing it.
Drop Cloths or Plastic Sheeting: To protect landscaping, windows, and any surfaces you don’t want to paint.
Painter’s Tape: For masking off areas like window frames, doors, and trim.
Safety Glasses: Protect your eyes from dust and debris.
Gloves: To protect your hands, especially when using cleaning solutions.
Respirator or Dust Mask: Essential during cleaning and sanding to avoid inhaling dust and particles.
Tools for Painting
Paint Roller with Extension Pole: A medium-nap roller cover (3/8″ to 1/2″) is usually best for brick’s texture. The extension pole saves your back!
Paint Brushes: You’ll need a few good quality brushes for cutting in edges, painting around windows, and tackling intricate areas. A 2- to 3-inch angled sash brush is a good choice.
Paint Tray or Bucket Grid: For holding your paint.
Paint Stirrer: To mix the paint thoroughly.
Ladder or Scaffolding (if needed): For reaching higher areas safely.
Step-by-Step Guide to Painting Outdoor Bricks
Let’s roll up our sleeves! Following these steps will give you a beautifully painted brick exterior that you’ll love for years.
Step 1: Inspect Your Bricks
Before you do anything else, take a close look at your brickwork.
Check for Damage: Look for cracked or spalling (flaking) bricks and crumbling mortar. These areas need to be repaired before painting. Painting over damaged brick won’t fix the underlying problem and can even make it worse.
Assess Previous Coatings: If your brick has been painted before, check for peeling or flaking paint. You’ll need to remove any loose paint.
Identify Efflorescence: This looks like a white, powdery residue on the surface of the brick. It’s a salt deposit that can come to the surface. It needs to be removed because it can prevent paint from adhering properly.
Step 2: Gather Supplies and Prepare the Area
Once you know what you need, it’s time to get set up.
Lay Down Drop Cloths: Cover any plants, walkways, patios, or other surfaces near the brick walls to protect them from dirt, cleaning solutions, and paint splatters.
Use Painter’s Tape: Carefully tape off windows, doors, trim, light fixtures, and any other areas you don’t want to paint.
Ensure Ventilation: Make sure you have good airflow if you are using any strong cleaning agents, and wear your protective gear.
Step 3: Clean the Bricks Thoroughly
This is arguably the most critical step for paint adhesion. Grime, dirt, mold, mildew, and efflorescence are enemies of a lasting paint job.
Sweep and Scrub: Start by sweeping the brick surface with a stiff brush or broom to remove loose dirt and cobwebs.
Apply Cleaning Solution: You can use a dedicated masonry cleaner, a solution of TSP (trisodium phosphate) substitute, or a mixture of 1 part bleach to 3 parts water. For stubborn dirt or mildew, a dedicated masonry cleaner is often best. Always follow the product instructions carefully.
Scrub Gently: Use a stiff-bristle brush to work the cleaner into the brick and mortar. Be gentle to avoid damaging the mortar.
Rinse Thoroughly: This is vital! Rinse the bricks extensively with a garden hose, working from top to bottom. You want to remove all traces of the cleaning solution. If you used a pressure washer, keep the nozzle moving and at a safe distance (around 18-24 inches) to avoid etching the brick or blowing out mortar. Start with the lowest pressure setting and increase only if needed.
Address Efflorescence: If you have efflorescence, use a mild acid solution (like a diluted vinegar solution – 1 part vinegar to 10 parts water) or a specialized efflorescence remover. Scrub and rinse thoroughly. For very stubborn efflorescence, a wire brush might be necessary, but use with care.
Step 4: Repair Any Damage
Now that the bricks are clean, it’s easier to see any repairs needed.
Mortar Repair: If you have crumbling mortar, use a masonry-specific patching compound or repoint the joints with a mortar mix. You might need a small trowel and tuckpointing tools for this. Let any repairs cure completely according to the product directions.
Crack Repair: Fill small cracks in the bricks or mortar with exterior-grade caulk. Smooth the caulk with a wet finger or putty knife to blend it in. For larger cracks in the brick itself, you might need a masonry repair epoxy.
Step 5: Allow Bricks to Dry Completely
Patience is key here! Painting over damp bricks is a recipe for disaster.
Drying Time: Depending on the weather conditions (temperature, humidity, and sun exposure), it can take anywhere from 24 to 72 hours, or even up to a week, for bricks to dry thoroughly after washing. You can check by pressing a piece of plastic wrap firmly against the brick for a day; if there’s condensation underneath, it’s still too wet.
Inspect Again: Before painting, give the bricks one last once-over to ensure they are clean and dry.
Step 6: Apply a Primer (Recommended)
While some paints can be applied directly, a primer designed for masonry will greatly improve adhesion and ensure a more uniform finish.
Choose the Right Primer: Use a high-quality, breathable masonry primer. Latex-based primers are good, but mineral-based primers are excellent for breathability.
Application: Apply the primer according to the manufacturer’s instructions using a roller and brush. Pay attention to details and ensure the entire surface is covered. Let the primer dry completely, usually for at least 4 hours, but check the specific product’s drying times.
Step 7: Apply the Paint
Now for the fun part!
Stir the Paint: Open your paint can and stir it thoroughly with a paint stirrer. Make sure to mix any pigment that may have settled at the bottom.
Cutting In: Use a paintbrush to “cut in” the edges of your brickwork. This means painting along the lines of windows, doors, trim, and any corners or edges where the roller can’t easily reach.
Rolling the Bricks: Load your roller with paint, but don’t overload it. Apply the paint in even strokes, working in manageable sections (about 3 feet by 3 feet). Aim for consistent coverage. Don’t try to force the paint into every tiny crevice; the texture of the brick will show through to some extent, which is part of the charm.
First Coat: Apply the first coat of paint evenly. Pay attention to maintaining a wet edge to avoid lap marks where one section of paint dries before the next is applied.
Step 8: Apply Subsequent Coats
Most exterior brick jobs will require two coats of paint for full, even coverage and durability.
Drying Time Between Coats: Let the first coat dry completely according to the paint manufacturer’s recommendations. This usually takes at least 4-6 hours, but can be longer in cool or humid conditions. Rushing this step can lead to adhesion problems.
Applying the Second Coat: Apply the second coat in the same manner as the first, ensuring good coverage and a consistent finish. Again, cut in edges first, then roll the larger sections.
Step 9: Clean Up
Once the painting is done and the paint has had a chance to set up slightly, it’s time to clean your tools and remove the protective coverings.
Clean Brushes and Rollers: For latex-based paints, clean your brushes and rollers with soap and warm water. For oil-based paints, you’ll need mineral spirits (check paint can for specific instructions). Store them properly if you plan to reuse them.
Remove Tape: Carefully remove the painter’s tape while the paint is still slightly wet (but not tacky) for the cleanest lines. If the paint is fully dry, score the edge of the tape with a utility knife before pulling it away to prevent peeling the new paint.
Dispose of Materials: Properly dispose of used drop cloths, cleaning rags, and empty paint cans.
Step 10: Allow Paint to Cure
The paint may feel dry to the touch fairly quickly, but it takes time to fully cure and harden.
Curing Time: Most exterior paints take about 30 days to fully cure. During this time, be gentle with the painted surface. Avoid scrubbing or harsh cleaning. This curing process ensures the paint reaches its maximum hardness and durability.

Important Considerations for a Sustainable Paint Job
As an eco-conscious gardener, I always like to think about how we can do things a little greener!
Low-VOC Paints: When choosing your paint and primer, opt for products with low or zero Volatile Organic Compounds (VOCs). VOCs are chemicals that can be released into the air and contribute to air pollution. Many eco-friendly brands offer excellent masonry paints with fewer harmful emissions.
Water-Borne Products: Generally, water-based (latex) paints and primers are more environmentally friendly than oil-based ones, as they clean up with water and produce fewer fumes.
Durable Finishes: Investing in high-quality, durable paint products means you won’t have to repaint as often, reducing waste and the resources needed for future projects. Mineral-based paints, while an investment, can last for decades.
Proper Disposal: Make sure to dispose of leftover paint, cleaning solutions, and materials responsibly according to your local guidelines. Many communities have special hazardous waste drop-off days.
Protecting Your Garden: As we’ve discussed, meticulous use of drop cloths and careful application will protect your plants and soil from chemicals and paint.
You can find more information on environmentally friendly painting practices and products from resources like the U.S. Environmental Protection Agency (EPA).
Frequently Asked Questions About Painting Bricks Outdoor
Q1: Do I really need to clean brick before painting?
A1: Absolutely! Cleaning is the most crucial step. Dirt, grime, mold, mildew, and especially efflorescence act as barriers, preventing paint from adhering properly. Without thorough cleaning, your paint job will likely peel, chip, or fail within a short time.
Q2: Can I paint over old, peeling paint on my brick?
A2: No, not without preparation. You must remove all loose and peeling paint using a scraper or wire brush. If there’s a lot of peeling, you may need to use a paint stripper or even pressure wash (carefully) to get down to sound paint or bare brick before you can proceed.
Q3: How long does paint for bricks outdoor last?
A3: This varies greatly depending on the quality of the paint, the preparation done, the climate, and the amount of sun and weather exposure. A high-quality, properly applied paint job on well-prepared brick can last anywhere from 7 to 15 years before needing a refresh.
Q4: Do I have to paint all my bricks? Can I just paint some?
A4: You can paint just a section or accent your brickwork if you choose. However, be aware that the appearance of painted versus unpainted brick can be quite different, so consider how the colors and textures will look together. Sometimes painting all the brick provides a more cohesive and intentional look.
Q5: Is it a bad idea to paint brick? Won’t it trap moisture?
A5: It can* be a bad idea if you use the wrong type of paint or don’t prepare the surface correctly. The key is to use breathable paint – like 100% acrylic latex or mineral-based paints – and to ensure the brick is clean and any existing issues are addressed. Manufacturers of quality exterior masonry paints understand these challenges and formulate their products accordingly. Always select a paint specifically recommended for exterior brick or masonry.
Q6: What’s the difference between masonry paint and regular exterior paint?
