Description

Stain Block Primer is suitable for containing unsightly stains caused by nicotine, smoke, marker pen, wax crayon, graffiti, tannin and bitumen, and can be over-coated with water-based emulsions.

It provides a tough, durable matt coating that prevents stains bleeding through from the substrate.

Stain Block will not prevent stains caused by water damage unless the fault has been eradicated and the substrate allowed to dry.


Non-yellowing formulation that penetrates deep into stains.


Features and benefits:

  • Seals problem surfaces.
  • Stops bleeding & stains.
