Product Overview

The OSI GreenSeries SC-175 Draft and Acoustical Sound Sealant is a non-flammable, latex-based sealant specially designed to reduce sound transmissions and drafts in all types of wall systems where sound-rated assembly is required. GreenSeries SC-175 is paintable, remains flexible and adheres firmly to wood, metal studs, concrete, drywall and most other building materials, while achieving and maintaining the specific STC (Sound Transmission Class) values and meeting LEED requirements. This sealant was developed primarily for commercial construction utilizing lightweight cavity walls and floor systems, ideal for use in office buildings, hotels, apartment complexes and other types of commercial and residential construction. Use it for exposed and unexposed applications at perimeter joints, floor and ceiling runners, cutouts in gypsum board, veneer plaster systems and other areas where a sound rated assembly is required. It can also be applied or buttered around all electrical boxes and outlets, cold air returns, heating and air conditioning ducts and other equipment penetrating wall surfaces for increased acoustical performance. In addition, it works well for sealing sill and base plates in residential construction.

Seems like a good product. Sealant consistantly leaks past caulking gun piston creating a mess and also wasting 1/4 to 1/5 of the caulk. An expensive mess.

    worthless as an acoustic sealant
    To work, acoustic sealants need to stay flexible. This junk shrinks and gets hard as a rock. I use it to fill large gaps solely for air sealing rather than flammable foams.

      Was very hard when it dried. Therefore I do not think it would be able to slow the transfer of sound

      Make sure this stuff is WARM when you want to use it. Don't even think about it if its around the 40 degree mark. Like may others have noted it didn't come out well. Squeezed out the back. I never let it freeze and had it warmed up in the truck all day and tried applying it on a 45 degree day or so and it was miserable. I wish I attempted to use it more but after struggling with 2 tubes I quit and plan on returning.

      Thank you for taking time to post your feedback. We are sorry to hear about your difficulty. The SC 175 is a latex, water-based product. Using this product does require a good grade caulking gun and a nozzle cut to proper size. Product temperature and ambient temperatures must be above 40°F as you noted. However, it is possible you may have purchased product that was old. Please reach out to our technical team at 1-800-624-7767 so we can obtain some additional information and help you.
