Sherwin-Williams has introduced the Extreme Block primer/sealer, an indoor/outdoor formula, to its coatings lineup.

The new oil-based primer reduces the need for repaints by sealing off stains such as smoke, fire and nicotine, making it ideal for quickly restoring a property to fresh condition.

This fast-drying primer can be top-coated with either acrylic or alkyd products in as little as two hours and adheres to multiple substrates including wood, drywall, masonry and prepared metal.
