Painting brick, stone, or concrete can dramatically transform your home’s appearance—indoors or out. But these surfaces require the right preparation, products, and techniques to ensure your paint adheres properly and lasts for years. Here’s a complete FAQ guide from the experts at Randall’s to help you do it right.
1. Can you paint brick, stone, or concrete surfaces?
Yes, absolutely! But unlike drywall or wood, masonry surfaces are porous and often dusty or uneven, which means they require special preparation and products—like masonry primers and mineral-based paints—to ensure lasting results.
2. What kind of paint should I use on masonry?
Choose paint specifically designed for brick, stone, or concrete, such as:
-
Masonry paint (formulated to breathe and prevent moisture trapping)
-
Acrylic latex paint (for flexibility and weather resistance)
- Elastomeric paint (for outdoor durability and crack resistance)
You can find suitable paints and coatings in Randall’s collections
3. Do I need to clean brick or concrete before painting?
Yes! This step is essential. Masonry surfaces often have dust, efflorescence (white powder), or mold buildup.
-
Sweep or vacuum loose debris.
-
Scrub with a mild detergent and water.
- For mold or mildew, use a mixture of water and vinegar.
- Let the surface dry completely before painting.
4. Should I use primer on masonry surfaces?
Yes, primer helps the paint bond properly. Use a masonry primer or sealer, especially if the surface is:
- New or unpainted
- Previously sealed or treated
- Exposed to weather or moisture
Priming prevents peeling and ensures uniform color coverage.
5. How do I prepare exterior brick or concrete for painting?
-
Power wash the surface to remove dirt and loose paint.
-
Repair cracks or chips using masonry filler.
- Allow the wall to fully dry (at least 24–48 hours).
- Apply masonry primer, then follow with your paint.

6. How many coats of paint do I need?
Typically, two coats provide even coverage and durability. For darker colors or highly textured stone, you may need a third coat to achieve a consistent finish.
7. Can I paint interior brick walls, like fireplaces or feature walls?
Yes! Painting interior brick can modernize your space instantly.
- Clean thoroughly to remove soot or dust.
- Use heat-resistant paint near fireplaces.
- Apply a bonding primer, then finish with an acrylic latex paint.
8. What’s the best way to apply paint to rough masonry surfaces?
Use the right tools:
-
Thick-nap roller (¾" to 1") for textured surfaces.
-
Masonry brush for deep grooves and corners.
- Paint sprayer for large, uneven exteriors.

9. Should I seal the painted surface afterward?
Sealing is optional but recommended for outdoor masonry. A clear masonry sealer adds protection against water, UV rays, and fading, extending the life of your paint job.
10. What are common mistakes to avoid when painting brick or concrete?
- Skipping cleaning or drying
- Painting over trapped moisture
- Using non-breathable paint (which can cause peeling)
- Not using primer or applying paint too thickly
11. How long does masonry paint last?
When properly applied, masonry paint can last 7–15 years depending on surface condition and exposure. Regular maintenance helps preserve its appearance.
