DAP’s newest wall & floor sealant, the Sound Block E90, is designed specifically to reduce sound transmission through penetrations in wall and floor systems, as well as improve STC ratings in sound-rated applications.

The sealant is recommended for use with openings around electrical boxes, pipes, duct systems, cut-outs, and other types of penetrating utility equipment, as well as abutting surfaces, corner joints, and other perimeter edges. It is tested to meet ASTM E90, C919 and E84/UL723, and also serves to reduce smoke and draft penetration.

“Sound Block E90 offers general contractors, builders and drywall installers an easy to use acoustical sealant for sealing top and bottom runners, cut-outs and perimeter joints that passes all industry standards for sound transmission while also reducing smoke migration and drafts,” says Justin Lingenfelser, product manager at DAP. “It is designed to gun easily and tool smoothly in all temperatures, not slump or sag, and maintain excellent adhesion on a variety of substrates.”

The Sound Block E90 is sold in 28 fl. oz. plastic cartridges designed for easy gun application. The formula is paintable within two hours, cleans up easily with water, and provides strong multi-material adhesion and strong cold weather performance. It will be available at lumberyards and building material distributors starting in June 2020.
