Brick exteriors are built to last, but painting them requires more than just grabbing a can of house paint. The key to a long-lasting finish lies in proper preparation and using breathable coatings that allow moisture to escape. Without the right approach, trapped moisture can cause paint to peel and brick to deteriorate. This guide walks you through the entire process—from cleaning and priming to selecting the best breathable paints and tools.
Why Breathable Coatings Matter for Exterior Brick
Brick is porous. It absorbs water from rain and humidity, then releases it as vapor. If you seal the surface with a non-breathable paint, moisture gets trapped behind the coating. This leads to blistering, flaking, and even spalling—where the brick face chips off. Breathable masonry paints (like limewash or mineral-based paints) or specially formulated acrylics allow vapor to pass through while protecting from weather.
Climate plays a major role in your choice. In humid regions or areas with freeze-thaw cycles, breathability is non-negotiable. For more on how weather impacts painting, read our guide on How Climate Affects Exterior House Painting: Hot, Humid, Windy, and Coastal Conditions?.
Essential Tools for the Job
Before you start, gather quality tools designed for rough masonry surfaces. A sturdy paint roller kit with an extension pole makes overhead work easier and ensures even coverage. We recommend two reliable kits that work well for both latex and oil paints.
Paint Roller Kit with Extension Pole
This 27-piece set includes an adjustable 2-to-4-foot pole, 4″ and 9″ rollers, and multiple brushes. Perfect for cutting in around windows and rolling large brick sections. Priced at $34.99 with a 4.4-star rating, it’s a solid choice for DIYers.
Bates Paint Roller Kit
The Bates 19-piece kit offers microfiber sleeves, an angled brush, foam brush, paint scrapers, and a tray. At $16.85 and a 4.6-star rating, it’s an excellent budget-friendly alternative with everything you need for exterior brick painting.
Step-by-Step Prep for Brick Surfaces
Prep is where most painting failures start. Follow these steps for a surface that will hold paint for years.
1. Clean the Brick Thoroughly
Dirt, moss, and efflorescence (white salt deposits) must be removed. Use a pressure washer on low-to-medium setting (avoid high pressure that can damage mortar). Alternatively, scrub with a stiff brush and a solution of trisodium phosphate (TSP) and water. Rinse and let the brick dry completely—at least 48 hours of dry weather.
2. Repair Mortar and Cracks
Inspect for loose or crumbling mortar joints. Repoint using a matching mortar mix. Let new mortar cure for at least two weeks before painting. Fill small cracks in brick with a masonry caulk. For larger damages, consult a professional.
3. Apply a Masonry Primer
Priming seals the porous brick, provides adhesion, and helps the topcoat breathe. Look for a high-quality primer specifically for masonry. One trusted option is Zinsser products. While the Zinsser PERMA-WHITE is formulated for interior mold and mildew resistance, its technology shows the brand’s commitment to durable coatings. For exterior brick, choose an exterior-grade masonry primer.
This quart of Zinsser PERMA-WHITE in eggshell white is a great example of a primer-paint combination that resists mildew—ideal for damp basement brick or interior accent walls. For exterior use, pair it with a breathable topcoat or use an exterior Zinsser primer.
Tip: If your brick is chalky or previously painted, apply a bonding primer first.
Choosing the Right Breathable Coating
Not all paints are suitable for exterior brick. Look for labels that say “masonry paint,” “breathable,” or “mineral paint.” Acrylic latex masonry paints offer good flexibility and vapor permeability. Limewash and silicate paints provide maximum breathability but require specific application techniques.
When painting in cooler weather, avoid applying paint below 50°F. Learn more in Cold‑weather House Painting: How to Paint Exterior Walls in Cooler Seasons Safely.
Applying Paint Like a Pro
Use a roller with a thick nap (¾ inch to 1 inch) to push paint into the brick texture. Start with a brush to cut in around edges and trim. Then roll the main walls in overlapping “W” patterns to avoid lap marks. Apply two thin coats rather than one thick coat—the second coat improves durability and evenness.
For south-facing walls that take the brunt of the sun, choose UV-resistant paint. Dive into Sun‑beaten Exteriors: Best UV‑resistant Paints and Techniques for South‑facing Walls for specialized advice.

Common Mistakes to Avoid
- Skipping the primer: Bare brick is too porous for direct paint—adhesion will fail quickly.
- Using non-breathable paint: Regular house paint traps moisture. Always use masonry-specific or mineral paint.
- Painting in direct sun: The paint dries too fast, causing lap marks. Work on the shady side of the house.
- Ignoring efflorescence: White salts must be removed before painting; otherwise they’ll push through the new coat.

Conclusion
Painting exterior brick is a rewarding project that transforms the look of your home. The magic is in the prep—clean thoroughly, repair mortar, and apply a breathable primer. Then choose a masonry paint formulated to let vapor escape. With the right tools like the Paint Roller Kit with Extension Pole or the Bates Paint Roller Kit, your job will go smoother and look better. For a reliable primer, consider the Zinsser PERMA-WHITE for interior brick or an exterior masonry primer for outdoor walls.
Take your time, follow the steps, and your brick walls will stay beautiful for years to come.
Frequently Asked Questions
Q: Can I paint brick without a primer?
A: It’s not recommended. Primer seals the porous brick, prevents the paint from being absorbed unevenly, and improves adhesion. Always use a high-quality masonry primer.
Q: What is the best breathable paint for exterior brick?
A: Look for acrylic latex masonry paint labeled “breathable” or “vapor permeable.” Mineral paints (silicate) and limewash are also excellent choices but require specific application skills.
Q: How long should I wait between coats on brick?
A: Follow the paint manufacturer’s instructions, usually 4–6 hours in good drying conditions. Cool or humid weather may require longer dry times.
Q: Can I paint brick in winter?
A: Only if the temperature is above 50°F and staying dry. Cold weather slows drying and can cause poor adhesion. Read our Cold‑weather House Painting guide for tips.
