Spray paint on brick can be more than just an eyesore—it’s a stubborn intruder that seeps into every crevice and resists ordinary cleaning. Whether it’s the aftermath of vandalism, accidental overspray, or remnants of a DIY gone sideways, figuring out how to get spray paint off brick requires more than elbow grease. It demands method, patience, and the right materials.
how to get spray paint off brick
Let’s break it down step by step.
Step 1: Assess the Surface – Not All Brick Is the Same
Start by examining the brick’s condition. Why? Because porous, unsealed brick absorbs paint much more readily than sealed or glazed surfaces. Older bricks are often softer, more brittle, and require a gentler approach to avoid irreversible damage.
- Is the brick sealed or unsealed?
- How long has the paint been on the surface?
- Is the graffiti or paint isolated or widespread?
These questions will guide your removal approach—what works on new, hard-faced brick may wreak havoc on an old Victorian facade.
Step 2: Begin with the Basics – Soap and Scrub
Before jumping into chemical solutions, start with a simple wash. It’s surprisingly effective if the paint is relatively fresh or lightly applied.
- Mix warm water with a mild detergent.
- Use a stiff nylon brush (not metal—metal can scar the surface).
- Scrub in small circular motions, applying steady but controlled pressure.
- Rinse thoroughly with water.
Didn’t budge? That’s expected. But it’s worth starting here—it loosens surface-level paint and preps the area for deeper treatment.
Step 3: Use a Masonry-Safe Paint Remover
When soap won’t cut it—and it often won’t for cured spray paint—you’ll need to bring in reinforcements. Choose a paint remover designed specifically for porous masonry.
- Look for gel-based or thickened formulas that won’t drip.
- Apply the product evenly with a synthetic bristle brush.
- Let it dwell. This part is crucial—give the remover time to penetrate the paint layers (typically 30 minutes to several hours).
- Avoid rushing. Premature scrubbing will only make the job harder.
Test on a small, inconspicuous patch before tackling large sections. Not all removers play nice with every brick type.
Step 4: Scrub, Rinse, and Repeat (If Needed)
After the dwell time:
- Use a wire or heavy-duty nylon brush to scrub the treated area.
- For large areas, a low-pressure power washer may help—but be careful. Excessive pressure can erode mortar and chip brick.
- Rinse thoroughly with clean water.
Still see paint residue? You’re not done. Spray paint removal is often a layered process. Multiple applications may be necessary, especially on rough, porous brick.
Step 5: Try a Poultice for Deep-Set Stains
When spray paint has bled deep into the brick’s pores, consider using a paint removal poultice.
A poultice is a paste made of an absorbent material and a solvent, which draws out embedded paint as it dries.
- Apply a thick coat of the poultice over the stained brick.
- Cover it with plastic sheeting to prevent rapid drying.
- Leave it in place for 24–48 hours.
- Remove the dried paste and inspect the results.
This method is time-intensive, but remarkably effective for historic or delicate masonry.
Step 6: Seal the Brick to Prevent Future Staining
Once clean, apply a breathable masonry sealer. This creates a protective barrier without trapping moisture inside the wall (a common issue with non-breathable sealants).
Benefits:
- Easier future cleanups
- Resistance to future spray paint adhesion
- Prolonged brick lifespan
Think of sealing as your final, defensive line.
Pro Tips and Things to Avoid
- Avoid metal scrapers or wire brushes on soft or weathered brick.
- Don’t use harsh acids (like muriatic acid)—they can permanently etch or discolor the surface.
- Don’t rely on high-pressure washing alone—it often drives the paint deeper into the surface.
Instead, work patiently and methodically. It’s not a quick fix, but it is fixable.
