Varnish and Paint Remover

Originally an oil based, colorless coating, varnish has come to include almost any coating with little or no color. This includes colorless polyurethane and epoxy. Add color to varnish and it's then called paint. Like other coatings, the chemistry of varnish and paint varies greatly leaving one wondering how to remove varnish and paint from a restoration project.

There are a number of methods that can be employed to remove varnish and paint: The more familiar include, media blasting, high pressure water blasting, grinding or sanding, heat, laser, chemical strippers, or some combination of these approaches. Chemical strippers offer significant advantages over other methods for varnish and paint removal: much lower airborne contaminants than media blasting, less effluent waste than high pressure water, less risk of substrate damage than heating, grinding, blasting, or lasers, and no need for costly application equipment. Varnish and paint removers do, however, have some environmental, health, and safety issues that must be considered. In the past, dangerous materials which comprise toxic poisons, carcinogens, severe skin irritants, hazardous air pollutants, and toxic wastes, were used as effective varnish and paint removers but, posed severe risks to the users and the environment. Fortunately, safer products are available today like our RonJohn® varnish and paint removers which are blends of raw materials that pose lower risk but, have powerful solvency.

For Removing Varnish and Paint, simply:

  1. Apply your RonJohn® paint remover by immersion, brush, or spray.
  2. Allow the solvent time to soften the paint (the amount of time necessary will vary by paint type, thickness, and temperature).
  3. Once the paint is softened, scrape it off with a sharp putty knife or paint scrapper.
  4. Reapply and scrape if necessary.
  5. To remove paint from textured surface or for removal of stain from wood, rub with scotchbrite type pad or fine steel wool.
  6. Clean residue from surface and allow to dry.
