Wall paint on sealed concrete.

DoyleS · Mar 4, 2024

We are in the process of building, doing alot of the inside side work ourselves and are ametaures... we have a concrete floor thst has been sealed with a water based sealer. We just for finished painting the walls and there is quite a bit of paint on the floors that will need to be removed. Some drips and several mishaps and alot of paint throughout. Can I use paint thinner on concrete floors without damaging the sealer?

Trying to find the quickest way to get its up thats easier than hands and knees. Thanks!

Drop cloths are the simplest and easiest way to handle this.

Water based sealer, tells me mineral spirts to remove paint will damage the seal.

Spray bottle then a razor scraper might do better

Another way to do it would be to use mineral spirits to remove the paint and then apply another coat of sealer to the entire floor.

Mineral spirits is not likely to have much effect on dried latex paint. Denatured alcohol will dissolve dried latex, don't know what effect it will have on the sealer BUT if you wish to keep the concrete unfinished that is about your only option and you can reapply the sealer once its clean.

Next time use drop cloths! cardboard next to the wall also works well.

Mineral spirits does NOT get dried paint up, people.....

I'd dampen the paint on the floor and cover with a piece of plastic or something. The moisture will work its way under the paint and loosen it. It might take a few days or a week. Then scrape it off with a plastic putty knife.
