Our Stain Block Aerosols are primer spray paints designed to be applied to stained areas and surfaes. The spray covers and blocks the stain, preventing it from showing through the topcoat once applied.
These stain block aerosols work on a variety of stains, from water marks and rust to nicotine and grease. They also function on a wide range of interior surfaces, allowing stains to be removed from anywhere in the home.
Once dried, the stain block leaves a smooth finish and can be painted over like a standard primer, the stain now unable to be seen through the chosen topcoat.
