5 Best Ways to Strip Old Paint from Old Bricks

Paint stripping in boston

Stripping old paint from brick walls can feel like peeling back layers of history. Those walls might have seen decades of changes. But whether you’re aiming for a restoration project, preparing for a fresh paint job, or simply want to bring the beauty of bare brick back to life, getting rid of stubborn old paint isn’t exactly an easy task. Don’t worry though, with the right paint stripping techniques and tools, you can make those brick walls shine again without damaging them.

Bricks are tough but porous, and some paint stripping methods can be a bit too aggressive, leaving your bricks chipped or discolored. The key here is to strike a balance – you want to get the paint off but keep the bricks harmless. Let’s dive into the five best ways to strip old paint from old bricks, so you can decide which one works best for your project.

1. Chemical Paint Strippers

Chemical paint strippers are one of the most popular and effective methods of paint stripping. These products break down the bond between the paint and the brick, allowing you to easily scrape or wash away layers of paint.

How to Use Chemical Paint Strippers on Brick

  • Start by covering the ground around the work area, and make sure you wear protective gear – chemical strippers can be harsh on your skin and harmful if inhaled.
  • Apply a thick layer of the stripper onto the painted surface with a brush or roller. Some strippers work best when applied thickly, so don’t be shy.
  • Wait for the chemical to work its magic. This usually takes a few hours but follow the manufacturer’s instructions. You’ll notice the paint starts to bubble and peel away.
  • Once the paint has loosened, use a scraper or a stiff brush to remove the softened paint.
  • Rinse the bricks thoroughly with water to remove any residual stripper and paint.

Chemical paint strippers are great for getting down to the fine details, especially on older, uneven bricks. However, these products can be tricky to handle, so work in well-ventilated areas and be cautious with waste disposal. The bonus is, it’s quite effective even on multiple paint layers.

2. Pressure Washing

Pressure washing is another effective method but should be used with caution when stripping paint from bricks. The high-powered water can wash off the paint, but it can also damage the surface of the brick if used incorrectly.

Steps for Pressure Washing

  • Choose a pressure washer with adjustable settings, and keep the pressure low – around 500 to 1000 PSI – to avoid damaging the brick.
  • Test the pressure on a small, inconspicuous area first to ensure the brick can handle it.
  • Hold the nozzle a few feet away from the brick and move it in steady, even strokes across the surface. Avoid holding the stream in one spot for too long, as this can weaken or erode the brick.
  • If the paint is stubborn, you can use a chemical stripper in combination with the pressure washer for better results.

This paint stripping method is fast and efficient but isn’t ideal for very old or delicate brickwork, as the power of the water could erode the brick’s outer layer.

3. Sanding

Sanding is a tried-and-true manual method of removing paint from surfaces, including brick. It’s a bit more labor-intensive method of paint stripping but can give you more control, especially when working with delicate or highly textured bricks.

Sanding Steps

  • Start with a wire brush or coarse-grit sandpaper to remove the top layers of paint. Work in circular motions, gently but firmly rubbing the surface.
  • For large areas, you can use an orbital sander or a sanding block, but be sure to use sandpaper that’s tough enough to remove paint without damaging the brick underneath.
  • Once most of the paint is removed, switch to a finer grit sandpaper to smooth out the surface and remove any remaining paint particles. 

Manual sanding can be a bit of a workout, but it’s effective for smaller areas or when you need precision in paint stripping of hard-to-reach spots. Just keep in mind, it can be dusty, so wear a mask and eye protection.

4. Use a Heat Gun

A heat gun can soften paint, making it easier to scrape off. This paint stripping method works particularly well on thicker layers of paint.

How to Strip Paint with a Heat Gun

  • Hold the heat gun a few inches from the brick and slowly move it over the painted area. The heat will cause the paint to bubble and loosen.
  • As the paint softens, use a scraper to carefully lift it from the surface.
  • Be mindful of the heat – bricks can absorb a lot of it, and overheating the surface could cause cracking or discoloration.

Heat guns are a good option for detailed paint stripping, but be cautious with their use, especially around old walls, which could become brittle and crack under intense heat.

5. Peel-Away Paint Strippers

If you’re looking for a low-mess option for your paint stripping project, peel-away paint strippers might be your best bet. This paint stripping method involves applying a thick paste to the brick, covering it with a special paper, and then waiting for the stripper to dry.

How It Works

  • Spread an adequate layer of peel-away stripper onto the brick using a trowel or spatula.
  • Press the paper backing over the stripper, smoothing it out to remove any air bubbles.
  • Leave the stripper in place for the amount of time recommended by the manufacturer (this can range from a few hours to overnight).
  • Once dry, peel away the paper, and the paint should come off with it.

Peel-away strippers are effective at removing multiple layers of paint in one go, and they’re a cleaner option for paint stripping compared to chemical strippers or sanding. This method is perfect for large projects where you want to avoid a lot of mess. 

Conclusion

Stripping old paint from brick can be a satisfying project, especially when you reveal the natural beauty hidden beneath layers of peeling paint. Whether you choose pressure washing or chemical strippers, there’s a method out there that’ll fit your needs.
