Sherwin-Williams’ newest coating product, the Extreme Block Primer/Sealer, is designed to quickly seal off tough surface stains, including fire, smoke, and nicotine, on both interior and exterior surfaces.

The oil-based primer adheres to multiple substrates, including wood, drywall, masonry, and prepared metal. The primer is easy to sand to a uniform surface, according to the manufacturer, and primed surfaces may be top-coated with either acrylic or alkyd coatings after as little as two hours of drying.

“Extreme Block joins other recently introduced coatings, such as Extreme Cover Stain Blocking Paint and Primer in One, as a key product in the property management and residential repaint toolkit,” says Steve Revnew, senior vice president of product innovation at Sherwin-Williams. “The fast-drying formula and powerful stain-blocking properties make it a great option for multifamily property managers, facility maintenance crews and other professionals looking to save time and maximize results.”
