How You Use a Paint Sprayer for Staining Wood
To use a paint sprayer for staining wood, first clean and dry the surface thoroughly. Set your sprayer with a 1mm nozzle, about 23 psi air pressure, and back the fluid needle 2.5 turns for light stain flow.
Hold the gun 6-12 inches from the wood, spraying in smooth, overlapping passes with the grain. Keep your speed steady for even coverage.
Also, avoid blotches by pre-wetting porous wood. Keep going, and you’ll soon master this skill.
