Rated for High-Performance
Formulated specifically to reduce drafts and sound transmissions, non–flammable soundproofing sealant helps achieve Sound Transmission Class values and meeting LEED requirements. Acoustical sound sealants also prevent condensation, air infiltration, offer long-term moisture barriers.
Latex-based, nonflammable sealants reduce drafts and noise transmission in all kinds of wall systems requiring sound-rated assembly. It’s also flexible, paintable and adheres securely to just about any other building material you’re using. Originally developed for commercial construction, soundproofing sealant is a must-have for noisy, multi-level office buildings, apartment complexes, hotels and residential buildings.
Where to Use Acoustic Sound Sealants
Acoustical sealant is the ideal product for filling cracks, gaps or merge points in various surfaces. Apply sound sealant to unexposed and exposed ceiling and floor runners, perimeter joints, veneer plaster systems and areas where you need a sound-rated assembly. Use it around electrical outlets, electrical boxes, HVAC ducts, cold air returns and equipment attached to wall surfaces for increased sound performance in rooms and recording studios.
How Acoustic Sound Sealants Work
Noise-proofing sealants form a flexible barrier over the areas where sound would otherwise escape to stop noise transmission. Flexibility is the key attribute.
Flexible acoustic sealant can absorb sound energy. When sound waves contact the flexible caulk, the material acts as a cushion that converts sound energy into heat and disperses it throughout the sealant.
Flexible acoustic sealant forms a longer-lasting barrier than other products. Hard sealants will crack, shrink or expand over time, which allows sound to pass through. Flexible acoustic sealants hold their form for consistent blockage.
But wait — there’s more! Soundproofing sealant is water-based. It cleans up with plain soap and water, won’t crack, harden or separate, and is UL-classified and tested. It won’t migrate, either, meaning wherever you put sound sealant, that’s where it stays. No oozing, running or thinning to mess with. Plus, it’s completely safe. Water-based sealants are non-toxic and non-flammable.
How to Apply Acoustic Sealant
One reason acoustic sealants are so popular is that they are easy to apply. You can seal numerous cracks in minutes, and the sealant will dry in two to seven days.
First, clean the surface before applying the sealant. Dust, dirt or moisture can prevent the sealant from holding properly. Scrape or sand away any debris, then use a knife or scissors to clear and widen the crack if necessary. The crack must be large enough for the material to get inside. We recommend an opening between 1/4 of an inch and 3/8 of an inch. Use a backer rod if the crack is larger than 1/2 an inch.
When the crack is ready to fill, it’s time to spray the sealant. Fill the crack entirely so there are no openings for sound to work through. Wipe away any excess sealant within 30 minutes using a paper towel or cloth.
