Removing Paint from Concrete: Three-Color Surface
If you’re dealing with a corner wall painted with three colors, you’ll need extra care to remove the paint without damaging the concrete underneath. Follow these steps:
Step 1: Protect Yourself and the Surrounding Area
Before you start, wear gloves, safety goggles, and a dust mask to protect yourself from chemicals and debris. To prevent damage, you should also cover any nearby plants or furniture with plastic sheeting.

Use a paint scraper or putty knife to remove any loose or flaking paint from the surface of the concrete. Be careful not to damage the concrete underneath.
Step 3: Apply Chemical Paint Stripper
Apply a chemical paint stripper to the remaining paint with a stiff-bristled brush. Follow the manufacturer’s instructions carefully, and let the stripper sit for the recommended time. The paint will begin to bubble and peel away from the concrete.
Step 4: Pressure Wash the Surface
Once the stripper has softened the paint, use a pressure washer to clean the surface. Use a fan tip nozzle to avoid damaging the concrete, and hold the wand at least 12 inches away from the surface.
