NGR Stain


Please explain NGR stain. – Bob St. Laurent


Terry Moore replies: Non Grain Raising stains use a different solvent for the pigment. Water based stain uses water as the solvent for the pigment, and applying water to wood raises the grain and makes it rough to the touch. Alcohol base stains use alcohol as a solvent, but there is still a percentage of water in the alcohol solvent, so it will also raise the grain slightly when applied.

NGR stains use a lacquer thinner base, or similar solvents that make up what we commonly call “lacquer thinner”, and these carry the pigments, dry faster and do not raise the grain because there is no water in the solvent.
