If you’re working with new, untreated wood, you’ll need to apply clear shellac to wood knots and open grains. This will block tannins that can bleed through the paint.
If you see a yellow or pink stain coming through the paint on older furniture – typically from the 1930s and 1940s – apply clear shellac. One or two coats of shellac applied with a cloth pad will stop this happening. It dries in minutes, and then you can get on with your painting!
