Ready-Strip PlusÖ, QUART SIZE now 50% stronger, is a one of a kind, environmentally friendly, paint and varnish remover capable of removing up to 7+ layers in one application. The revolutionary "Color Change" feature signals the time for paint removal. The stripper is applied to the surface and turns off-white or a pale green when the paint or varnish is READY to be removed. Ready-Strip Plus is non-flammable, biodegradable, virtually odorless and can be cleaned up with water. It does not contain methylene chloride, caustic, flammable chemicals or harmful vapors like many traditional strippers. Ready-Strip Plus avoids the uncertainty associated with other strippers that are ineffective if removed too soon, or dry out and not work if left on too long. Ready-Strip Plus not only eliminates the guesswork, but will strip 3-4 times more paint or varnish. Unlike other strippers, Ready-Strip Plus is a semi-paste and therefore truly clings to vertical surfaces.
