Why You Need to Remove Paint from Concrete

Paint doesn’t just look out of place on concrete—it can compromise the surface’s durability and prevent sealers from working effectively. Removing paint ensures a clean, professional finish that’s ready for sealing or refinishing.

How to Remove Paint from Concrete: Step-by-Step Guide

1. Start with Surface Cleaning

Before tackling paint removal, sweep and clean the concrete to remove any loose dust and dirt. This helps the removal solution work more effectively.

2. Use Methylated Spirits for Water-Based Paint

For water-based paints, methylated spirits (metho) is a surprisingly effective solution:

Pour methylated spirits directly onto the paint spots.
Work it into the concrete using a long-handled brush.
Methylated spirits act as a solvent to dissolve water-based paints.
Be quick! Methylated spirits evaporate rapidly.
Once the paint starts to lift, rinse the area thoroughly with water.
Let the concrete dry for 1–3 hours.
If residual stains remain, use a pressure washer to remove bleached marks.

Important: Always wear gloves and work in a well-ventilated area when using methylated spirits.

3. Use a Paint Stripper for Tough Stains

For stubborn or oil-based paints, consider a more powerful chemical stripper. We recommend the eco-friendly Nu EcoSafe Architectural Paint Stripper for safe and effective paint removal.
