Best Practices for Paint Removal on Brick & Concrete
Whether you’re the proud owner of a vintage property cloaked under layers of paint accumulated over the years, or a contractor working to revive a brick or concrete structure to its original allure, you’ve got a tricky job on your hands.
Removing paint from brick and concrete surfaces involves a variety of complex factors, including the number of paint layers, the type of paint, and how firmly it adheres to the surface.
In some cases where the condition of the brick is poor, removing the paint might cause further damage, especially to the mortar. However, with careful planning and the right methods, paint can be removed, and the brick can be repaired or restored.
When it comes to paint removal, there’s no one-size-fits-all solution. The effectiveness of any method – or combination of methods – will largely depend on the specifics of the project.
Cutting Through the Layers: Choosing the Right Method
Each paint removal method has its advantages and disadvantages. Here’s an overview of the options:
| Method | Pros | Cons |
|---|---|---|
| Abrasive Blasting | ✓ Can adjust pressure and test different media | ✘ May damage brick/concrete ✘ Cleanup and containment requirements can be tedious and expensive ✘ Risks of contamination issues with lead paint (requires trained and certified contractor) |
| Power Washing | ✓ Little to no dust | ✘ Potentially toxic runoff ✘ Water usage restrictions and disposal can be costly |
| Sponge Blasting | ✓ Low-dust method ✓ Less time needed for containment and cleanup | ✘ Could damage old brick |
| Dry Ice Blasting | ✓ Faster cleanup, less containment needed ✓ Lower risk for lead paint removal | ✘ Can still damage brick |
| Paint Stripper | ✓ Easiest disposal for lead paint | ✘ Very slow ✘ Caustic chemicals may damage old brick |
