How to Remove Paint from Brick

Painted brick is a polarizing topic — some love the look, others want to restore the natural brick beneath. Removing paint from brick is one of the most labor-intensive paint removal jobs because brick is highly porous and paint penetrates deeply into its surface. But with the right products and patience, it's achievable. Here's how to remove paint from brick walls, fireplaces, and exterior surfaces.

Tools You'll Need

• Citristrip paint stripping gel — safe for masonry, effective on multiple paint layers
• Paint scraper set — for removing softened paint from brick face
• Drill brush set — for scrubbing paint from brick texture and mortar joints
• Respirator mask — essential when working with chemical strippers
• Chemical resistant gloves — for handling strippers
• Safety goggles — for eye protection

Understanding the Challenge

Paint on brick is fundamentally different from paint on wood or metal. Brick is extremely porous, and paint — especially latex paint applied in multiple coats over many years — penetrates deep into the brick's surface. Complete removal is possible but may require multiple treatment cycles and significant effort. Older lime-based paints (common on pre-1950s brick) are particularly difficult to remove.

Step 1: Test a Small Area First

Before treating the entire surface, test your removal method on a small, inconspicuous area. This lets you assess how the brick responds and how many treatment cycles will be needed.

Step 2: Apply Citristrip Generously

Apply a thick coat of Citristrip gel over the painted brick. Citristrip is safe for masonry and won't damage the brick or mortar. Apply at least 1/4 inch thick and cover with plastic sheeting to prevent drying. Leave for 4–24 hours — the longer the better for multiple paint layers.

Step 3: Scrape and Scrub

Remove the plastic and use a paint scraper to remove the bulk of the softened paint from the brick face. Follow with a drill brush to scrub paint from the brick's texture and mortar joints. Rinse with water and assess.

Step 4: Repeat as Needed

Multiple layers of paint on brick typically require 2–4 treatment cycles. Apply Citristrip again to any remaining paint and repeat the scrape-scrub-rinse process.

For Exterior Brick: Pressure Washing

After chemical stripping, a pressure washer (2000+ PSI) is highly effective for rinsing paint residue from exterior brick. The high-pressure water reaches into the brick's pores and mortar joints more effectively than a garden hose.

Managing Expectations

Very old paint on brick may leave a faint ghost image even after thorough treatment. This is normal and doesn't indicate failure — it's simply paint that has permanently bonded with the brick's surface. A brick sealer applied after cleaning can help minimize the appearance.

Removing paint from brick is a commitment, not a quick job. Citristrip, a drill brush, and multiple treatment cycles are your best tools. Work systematically, protect yourself with proper safety gear, and the natural brick will gradually emerge.
