Dunn-Edwards has introduced Block-It Premium, a new, high-performance stain-blocking primer. Block-It Premium is made with a waterborne alkyd formula that provides adhesion, hide and stain-blocking properties. It is recommended for use on an array of previously painted or new interior and exterior surfaces. Block-It Premium’s stain-blocking performance derives from utilizing waterborne alkyd resins, barrier-type pigments and stain-blocking additives that form a smooth, tight film over the stain, locking it in place and preventing it from migrating through the topcoat. This primer can be used on surfaces such as drywall, wood and acoustical ceilings. It is effective in hiding tough stains caused by food, grease, water or smoke damage, ballpoint or felt pen ink, lipstick, crayon and tannin bleeding on woods. Block-It Premium is eco-friendly and ethylene glycol (EG)-free. For more information, visit www.dunnedwards.com.
