Dunn-Edwards Corp. (Los Angeles, Calif.) introduced Block-It Premium, described as a high-performance stain-blocking primer based on a water-borne alkyd formula that provides strong adhesion, hide and stain-blocking properties.
The product is recommended for use on a variety of previously painted or new interior and exterior surfaces.
The company said the primer’s stain-blocking performance is the result of a formula that incorporates water-borne alkyd resins, barrier-type pigments and stain-blocking additives that combine to form a smooth, tight film over the stain, locking it in place and preventing it from migrating through the topcoat.
The primer can be used on drywall, wood and acoustical ceilings, and is effective in hiding tough stains caused by food, grease, water or smoke damage, ballpoint or felt-pen ink, lipstick, crayon and tannin bleeding of woods. The primer is described as eco-friendly and free of ethylene glycol.
David Hsia, product manager, said the primer combines the application qualities of an oil-based paint with the convenience and benefits of a water-based product. Other characteristics include very low VOCs; low odor; sandability; and superior flow and leveling with brush and roller application, he said.
