Our shellac solution is specially designed to isolate knots and resin-rich areas in wood before painting. It effectively prevents resin bleeding and knot stains from showing through the paint layer, creating a natural barrier. It is also known as knot sealer.
Water-based shellac primer for indoor walls.
If the substrate is highly absorbent, such as raw plaster or fabric, the surface can be pretreated with primer. The primer reduces paint consumption and the risk of bleed-through from water damage, soot, and nicotine.
