Green Glue Noiseproofing Sealant is the best finishing acoustical sealant for your soundproofing application, stopping sound dead in its tracks. Seams and cracks in walls, ceilings and floors can allow sound to leak out and transfer between two spaces, but our flexible Sealant is designed to plug those gaps and remain effective for years to come.
Green Glue Noiseproofing Sealant is a high-performance alternative to standard latex or silicone caulk for interior acoustical applications. The damping properties of this product provide better acoustical performance than standard finishing methods, meaning better protection against sound transfer. It is non-hazardous, has practically no odor and resists drying out or cracking with age. Having been independently tested by Underwriters Laboratories for fire, smoke, and environmental impact, our Sealant offers safe and effective protection against sound, while remaining focused on the sustainability.
Noiseproofing Sealant installation considerations
When installing Sealant, the size of the gap being filled is what matters most. It is recommended to leave a 1/8 - 1/2 in (0.3 - 0.6 cm) maximum gap around the perimeter of your wall or ceiling drywall to fill with Sealant; if the gap is larger, the Sealant will not cure properly. Once the Sealant has been applied to the wall seems, allow 48 hours to dry before covering it with standard finishing materials, such as mud and tape. Our Sealant can be painted over and will continue to block sound once it has been covered.
Some details to keep in mind when using Green Glue Noiseproofing Sealant:
A good rule of thumb is that for every 6 tubes of Green Glue Noiseproofing Compound, you will need one tube of Sealant
Sealant can also be used to fill small gaps around switch boxes, outlets and interior windows to stop noise from sneaking in
You can use the same 32-oz caulking gun used to apply Compound to also apply Sealant
Sealant does not offer any protection or seal against water and should only be used in interior applications
