5 ways to clean a surface before repainting

Removing paint from concrete can be a daunting task, but it's a necessary step when repainting or restoring a concrete surface. Whether you're looking to remove paint from a concrete floor, wall, or outdoor surface, there are several methods to choose from. In this blog post, we'll take a closer look at some of the most popular methods for removing paint from concrete. We'll also discuss the pros and cons of each method and provide some tips for achieving the best results. 

There are several methods for removing paint from concrete, including:

  1. Using a paint stripper: This is a chemical solution that is applied to the painted surface and left to sit for a specified amount of time. The paint will then peel or flake off, allowing it to be scraped or brushed away.

  2. Sandblasting: This method involves using high-pressure air to blast sand or other abrasive materials onto the painted surface, effectively sanding it away.

  3. Power washing: This method uses high-pressure water to blast away paint and other debris from the surface of the concrete.

  4. Using a wire brush or scraper: This method involves manually scrubbing away the paint using a wire brush or scraper.

  5. Heat Gun: Use a heat gun to soften the paint, then scrape it off with a scraper or putty knife.

It's important to use the appropriate safety gear and follow the manufacturer's instructions when using any of these methods. And be aware of the environmental impact of the chemicals used.
