Paint removers, or strippers, are not merely one chemical, but a combination of them, each with a specific job to do. These pages provide information on solvent-based removers, those that use chemical solvents to remove the old finish. Solvent-based strippers come in three forms: liquid, heavy bodied, and semi-paste. In general, the liquid works best for varnish and lacquer finishes on such things as antiques with flat horizontal surfaces. The heavy-bodied and semi-pastes are very similar with the semi-paste being slightly thicker.
