I want to re-do my floors with a painting technique I found; however, I do not know how to clean the floors that have the old painters paint, I do not want to use any caustic chemicals if possible. Thank you all in advance.

    If your painting you can paint over the old finish. Another option, though messy, would be to have the floors sanded or ground.
  • You can rent a scarifer that works like a floor polisher but only heavy duty. These devices have special grinding wheels attached to the bottom that will remove paint quite quickly. You need to move around fast or you will end up with a hole in the cement. Its a heavy machine, but works really well. I have used them in the past to prep basement floors for epoxy paint.

      @Woodbridge Environmental - Wow! Thank you. Good advice.
  • Sanding will not remove the paint from your concrete floors. You have two options. One option would be to use a product called "Soy Gel" or "Beanie Doo" Both are non chemical, natural based products that soften the paint and then you can scrape it off. Very slippery and messy when working with these products but they do work. Don't use a scarifier as it will be too aggressive and and possibly gouge your floor. A grinder works well and is what we usually use. Either a 7 inch grinder with a diamond cup or a stand up grinder. You can rent these at some of the Home Depot rental departments. Good luck.

    I removed paint from a ad on room with water and a razor. I soaked it and put a razor on the end of a pole and scraped it off. Every single flake of paint came off. I soaked sections of the floor with water and scraped it off. I am not a professional but it worked prefect for me.

    There is a product called Soy-Gel. Non toxic and you can use it over and over again. Put it on cover with plastic leave for a couple of hours and up the paint comes. Look here at this mans website and can learn all about it.Look through his tips to learn more on this product. I get nothing for this just have used his stuff and ideas.
