How To Identify Oil Based Paint

A. There are a number of ways to determine if your paint is oil based and not latex based.

Take denatured alcohol or Liquid Sandpaper and rub it on latex and some paint will be removed and the surface will get tacky and sticky -- but on oil it won't take off paint or get tacky. Also, latex paint will mark easily with a silver coin, oil paint will be harder to mark.

Latex paint will soften with a solvent like lacquer thinner or Goof Off as well. Latex paint will probably not be as smooth; brush marks or roller stipple will be more evident. Latex paint may scratch off easier or even chip off, it will also soften in high humidity.
