You can dress up just about anything with a coat of paint. Yet, many homeowners hesitate to bring new life to a porch or entryway because it’s concrete. The truth is, you don’t have to settle for a stained, chipped, or just bland entry. Preparing concrete for painting is the key to great results in updating your concrete porch or entryway.
That’s because any imperfections you don’t deal with before the paint hits the floor can wind up showing through the paint, or even worse, preventing a perfect bond. Master these simple steps the pros use for preparing concrete for painting, and you’ll get great results in this home improvement project.
If your concrete is new, allow it to cure for at least 30 days. Even longer, up to 90 days, is ideal to ensure the pH will be at the proper level to allow it to bond with the paint. But if you have new concrete in great shape, you’ll be able to skip a lot of prep work, including scraping old paint, filling cracks, sanding, and degreasing. A quick wash and dry, and you’ll be good to go.
Plants, furniture, mats, etc., need to be stowed away. If you have hanging plants, we recommend taking those down for now, too. This will prevent dirt, water, or leaves from landing on your concrete surface.
This quick and easy step will protect your landscape from debris and any chemicals you may need to use to clean the concrete. While you’re there, trim any overhanging branches or ones touching the concrete.
If you’re going to paint metal or wooden railings, clean and prep them now. By doing that now, you won’t have clean your concrete a second time.
Scrape off anything loose or sticky with a flat scraper. If there is existing paint, remove as much as you can with a wire brush and then sand the edge of any remaining paint spots. If you are dealing with paint, see the critical safety note at the end of this article.
It’s always good to clean as you go, so sweep up now before you use any fillers.
Use concrete compound filler to fill in all holes, scratches, chips, and gouges in the concrete. After allowing sufficient dry time, sand the repaired areas until they are smooth.
This is a critical step to ensure a good bond between the paint and the concrete. Its complexity depends on what’s on your concrete.
Thoroughly hose off the concrete, washing away any chemicals and debris. Do this several times to ensure a completely clean surface. If you already have a pressure washer, you can certainly use it but renting or buying one is not necessary for great results.
Depending on the weather, a concrete floor can take up to two days to dry completely, so be patient! If your surface is not totally dry, you may end up with bubbles in the paint or peeling down the road.
After your concrete is dry, run your hand over the surface. It should feel like sandpaper. Make sure the texture of the surface, especially any patched areas, is consistent.
Use painter’s tape and paper to protect any areas you won’t be painting.

If your concrete was painted initially prior to 1978, you’ll
not only have some really old paint, you may also have a safety hazard. That’s because it may have been coated with lead paint. If you scrape or sand this paint, you may release lead dust or fumes, which can cause serious illness. Check the
guidelines provided by the National Lead Information Center for advice on how to proceed.
