The term 'lacquer' originally referred to wood finishes that dried by the evaporation of solvent from the blend. Today, 'lacquer' is used more generally to refer to paints and coatings that dry to an unusually hard and smooth surface consisting of almost any polymer dissolved in solvent. You could encounter lacquer coatings in almost any application. Like other coatings, the chemistry of lacquers varies greatly leaving one wondering how to remove lacquer from a restoration project. When the need arises, you remove lacquer as you would other types of coatings.
There are a number of methods that can be employed to remove lacquer: 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 removing varnish: 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. Chemical strippers 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 lacquer removers but, posed severe risks to the users and the environment. Fortunately, safer products are available today like our RonJohn® paint and adhesive removers which are blends of raw materials that pose lower risk but, have powerful solvency.
How to Remove Lacquer:
- Apply your RonJohn® lacquer remover by immersion, brush, or spray.
- Allow the solvent time to soften the varnish (the amount of time necessary will vary by paint type, thickness, and temperature).
- Once the lacquer is softened, scrape it off with a sharp putty knife or paint scrapper.
- Reapply and scrape if necessary.
- To remove lacquer from textured surface or for removal of stain from wood, rub with scotchbrite type pad or fine steel wool.
- Clean residue from surface and allow to dry.
