Brick is tough, textured, and porous—characteristics that make it both resilient and tricky when it comes to painting. The question isn’t just can you paint brick, but what paint to use on brick to ensure long-term performance without sacrificing the structure’s breathability or aesthetic charm.
Let’s break it down: not all paints are created equal, and when it comes to brick, choosing the wrong type could lead to blistering, peeling, or moisture damage down the line. But with the right approach and materials? It can completely transform a space—inside or out.
Why You Can’t Use Just Any Paint on Brick
Before grabbing a generic can of latex paint, understand that brick isn’t like drywall or wood. Its porous surface absorbs moisture and needs to “breathe”—a key factor often overlooked by homeowners.
If the paint you apply seals the surface too tightly, it traps water inside the wall. That water doesn’t just sit quietly. Over time, it can freeze, expand, and crack the brick face (a problem called spalling). What started as a cosmetic project can quickly become a structural issue.
That’s why breathability is non-negotiable. The right paint allows vapor to escape while still protecting the surface from rain, humidity, and UV exposure.
What Paint to Use on Brick: The Essentials
Here are the most trusted options when painting brick:
1. Mineral-Based Paint (Silicate Paint)
- Breathable, long-lasting, eco-friendly.
- Bonds chemically with brick, creating a natural-looking finish.
- Doesn’t peel or trap moisture.
Silicate paint is often considered the gold standard for masonry surfaces. It doesn’t form a film over the brick but penetrates it, ensuring exceptional longevity—sometimes lasting decades without flaking.
2. Acrylic Latex Paint (Masonry-Specific)
- Flexible, durable, and UV resistant.
- Only suitable when paired with a breathable masonry primer.
- Good for both interior and exterior applications.
High-quality acrylic latex is an acceptable option for painting brick, but only if it’s formulated specifically for masonry. Be cautious: standard latex paints won’t hold up over time and often lack the flexibility to cope with brick’s natural expansion and contraction.
3. Elastomeric Paint (With Caution)
- Water-resistant and thick.
- Seals hairline cracks but can trap moisture if misapplied.
Some professionals use elastomeric coatings on severely weathered brick, but it’s a double-edged sword. While it offers a strong waterproof barrier, it can prevent brick from breathing, especially in humid climates. Proper surface prep and ventilation are critical.
Important Tip: Always Use a Masonry Primer
Regardless of the paint you choose, never skip the primer. A masonry-specific primer ensures better adhesion and helps balance porosity. It prevents the brick from soaking up too much paint too fast, which can lead to blotchy, uneven finishes.
Interior vs. Exterior Brick: Is There a Difference?
Absolutely.
- Interior brick walls usually face fewer moisture issues, so acrylic-based paints are more common indoors.
- Exterior brick, exposed to the elements, demands extra care. Breathability, UV protection, and water resistance become vital.
Think of it this way: your interior brick may be a design feature, but your exterior brick is a shield.

Final Thoughts: The Best Paint Is the Right One for the Job
Painting brick isn’t just a weekend DIY decision—it’s a commitment. The type of paint you choose will determine whether that bold new look lasts for years or starts to peel after the first frost.
So, what paint to use on brick? Go for breathable, masonry-compatible products. Prioritize longevity over convenience. Whether you’re enhancing a cozy fireplace or giving your home’s exterior a modern edge, the right paint—matched with proper prep—makes all the difference.
