Dunn-Edwards has introduced Block-It Aerosol, interior/exterior stain-blocking primer in a 13-oz. spray can. It is a high-hiding, all purpose, primer sealer and stain blocker. It is ideal for use in sealing and blocking stains caused by water, nicotine, smoke, tannin, pencil, ink, grease and felt marker, according to the company.  Block-It Aerosol seals smoke and pet odor, and can be used on interior/exterior wood, concrete, drywall and non-galvanized metal.

“Block-It Aerosol is a great ’go-to’ primer, sealer and stain blocker that contractors can count on to spot prime those unique stains that seem to appear on every repaint project,” said Dave Heiligenthal, product manager.

Block-It Aerosol sticks to hard-to-paint surfaces such as railings, shutters, glossy paint, glass, ceramic tile and outdoor furniture. It sands easily and can be used for sealing spackle, drywall repairs and hiding dark colors. As with any aerosol product, Block-It Aerosol should be used only where there is adequate fresh air ventilation and should not be used near any open flame, such as an oven or water heater pilot flame.
