The new oil-based primer reduces the need for repaints by sealing off stubborn stains such as smoke, fire and nicotine, for 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 well to multiple substrates including wood, drywall, masonry and prepared metal, according to Sherwin-Williams.
