How to use latex paint over oil based paint?

If you want to use latex-based paint over oil-based paint, you will have to sand it first. Oil-based paint has a very smooth surface, so any paint that goes over it has a hard time sticking to it. To sand your wall, take a piece of sandpaper and wrap it around a block. Make sure you lightly buff the surface of the oil-based wall to create a rough surface that the latex paint will stick to. You’re not trying to strip the wall, just rough it up a bit, so don’t go too hard on the wall. To check if you’re dealing with oil-based paint, wash a small section of the wall with warm water and detergent. Next, dab a cotton ball that has been soaked in rubbing alcohol. If the paint comes off with the cotton ball, it’s a latex-based paint and you don’t have to sand it. If the paint doesn’t come off, you have oil-based paint and you will have to sand it.
