Johnstone's Trade Advanced Stain Block Primer is a shellac-based, heavy duty stain blocker that is ideal for sealing tar, bitumen and creosoted surfaces to prevent bleeding through in subsequently applied solvent-based paints. Our Advanced Stain Block Primer seals stains in timber, wood composites, plaster, cement and brickwork, as well as locking in unwanted odours.
