Painting exposed brick is one of the most effective ways to modernize a home, retail store, or office space. Whether you want to brighten a dark room with a crisp white finish or create a dramatic, moody feature wall, painting interior brick walls transforms the entire feel of a property.
However, brick is porous, textured, and unforgiving if treated incorrectly. Unlike smooth plasterboard, it requires specific preparation, the right masonry products, and a strategic application method to ensure the paint bonds for the long term.
In this guide, we will walk you through the exact process we use as professional commercial painters in the Northern Beaches, breaking down the tools, costs, and techniques required for a flawless finish.
Why Professional Execution Matters
Many property owners attempt this as a DIY project, only to find the paint peels or the mortar lines look patchy. When you hire a top-rated commercial painter in the Northern Beaches, you are investing in:
-
Proper Adhesion: Using correct masonry primers to prevent peeling.
-
Uniform Coverage: Ensuring deep mortar joints are fully coated without drips.
-
Time Savings: Professional spray equipment can finish a large commercial space in a fraction of the time.
How to Paint Interior Brick Walls: The Step-by-Step Process
If you are wondering how to paint an indoor brick wall correctly, the secret lies in the preparation.
1. Surface Preparation (The Most Critical Step)
You cannot paint directly over dusty or dirty brick.
-
Clean: Scrub the wall with a stiff bristle brush and a sugar soap solution. This removes decades of dust, soot, and grease.
-
Rinse: Wipe down with clean water and allow it to dry completely (often 24-48 hours).
-
Repair: Fill any deep cracks in the mortar with a flexible acrylic gap filler.
2. Priming the Brick
Do we need to seal the bricks first with anything? Yes. Brick is like a sponge. If you skip primer, the brick will suck the moisture out of your topcoat, leading to a patchy, weak finish.
-
Product: Use a high-quality water-based masonry primer for interior brick.
-
Application: A sprayer is best for deep mortar lines, but a thick-nap roller works for smaller areas.
3. Application Technique
-
Cut In: Use a brush to paint the edges and deep mortar joints first.
-
Roll or Spray: For the face of the bricks, use a high nap roller for brick (typically 20mm-32mm nap) to get into the texture.
-
Coats: Two coats of premium acrylic latex paint for masonry are standard for a solid, opaque finish.

Frequently Asked Questions
How to prepare the surface and what to use?
You must remove all dust and efflorescence (white salts). Scrub the wall with a wire brush to remove loose mortar, then wash thoroughly with sugar soap and warm water. Allow it to dry fully before priming.
Do we need to seal the bricks first with anything?
Yes. You must apply a specific masonry primer or a “block filler” primer. This seals the porous surface and provides a stable base for the topcoat to stick to.
How to paint interior brick walls in the kitchen?
Kitchen bricks face grease and steam. Use a high-quality semi-gloss or satin enamel which is easier to wipe down than flat paint. Ensure you degrease the bricks thoroughly before painting.
Can I spray paint interior brick walls?
Yes, spray painting interior brick walls is the most efficient method for large areas. It drives paint into the deep pores and mortar lines that rollers often miss, providing a smoother, more uniform finish.
