How to Clean Paint Off Concrete

Introduction

Paint spills on concrete can be stubborn because the porous surface absorbs and grips onto paint. With the right tools and methods, you can lift both fresh and old paint safely and restore the appearance of your driveway, patio, garage floor, or basement.

What You'll Need

• Paint scraper or putty knife

• Stiff-bristle brush

• Paint remover or concrete-safe solvent

• Warm water and mild detergent

• Pressure washer (optional)

• Absorbent towels or rags

• Protective gloves and eyewear

Steps

Remove any loose or peeling paint with a scraper to expose the areas that need deeper cleaning.
Apply a concrete-safe paint remover or solvent to the stained area and let it sit according to product instructions.
Scrub the softened paint using a stiff-bristle brush, working the solvent into the concrete pores.
Rinse the area thoroughly with warm, soapy water to lift dissolved paint residue.
Repeat the process for stubborn or older paint that has deeply penetrated the concrete surface.
Use a pressure washer on outdoor concrete to blast away remaining paint and reveal a clean finish.
Allow the area to dry completely before assessing whether additional treatment is needed.

Alternative Methods

• Use a heat gun to soften paint before scraping

• Apply a baking soda and hot water paste for lighter stains

• Use a commercial concrete degreaser for oil-based paint residues

What NOT to Do

• Do not use metal grinders unless you are trained—this can permanently damage the concrete

• Do not mix chemical solvents, as this can create dangerous fumes

• Do not skip protective gear—solvents can irritate skin and eyes

FAQs

Can I remove paint from concrete without chemicals?

Yes. Methods like pressure washing, using a heat gun, or scrubbing with baking soda paste can work for mild stains, though deeper or older stains usually need a solvent.

Will paint remover damage my concrete?

Most paint removers labeled “concrete-safe” will not cause damage when used as directed. Always test a small area first.

How do I remove spray paint from concrete?

Spray paint typically requires solvent-based removers plus vigorous scrubbing. A pressure washer can help lift paint from outdoor surfaces.
