Hi, I am having some trouble figuring out what to do about my basement store room that I need to turn into an office. the room is about 12x13 feet, has two walls framed out, and the other two walls are concrete. What I would like to do is leave the concrete walls and floor and go with a more modern/contemporary rustic look. The problem is that the previous owner in all her brilliance decided to paint the concrete purple on the walls and gray on the floor. I have read countless articles online about the process of putting in an epoxy paint or acid stain, and they all seem to suggest that stripping any existing paint and having a porous surface to promote adhesion is essential. I have not been able to find a lot of information on how to treat the walls. Is it difficult to chemically strip paint from concrete? If so, what are my alternatives? Are there any epoxies or anything that don't require the old paint to be stripped to adhere? What are some techniques for painting or treating the walls? I am also open to a more traditional look with a laminate floor and drywall, but the problem with that is that the concrete wall perpendicular to the door juts out awkwardly and I am afraid that if I framed it out there would be no room for the door to open. I have heard that furring strips can also be used but I am not sure if they will adhere to a very rough surface like the one i have on my walls. Attached is a pic of that corner; any help/advice would be greatly appreciated! Thanks!
You can paint directly on top of the existing paint, as long as it is not peeling or chipping off. Your paint does not have to be an epoxy.
Furring strips are attached with masonry nails or masonry screws so they too can be applied directly on top of the existing paint.
It will be very difficult if not impossible to do any kind of stain. For stain, you do need to strip 100% of the old paint off - something that is not going to happen with porous concrete.
