Green Glue Sealant

Easy to install and paintable once it dries completely, Green Glue Sealant provides a “finishing touch” after you install Green Glue Noiseproofing Compound. Use our Green Glue Noiseproofing Sealant to fill gaps and joints where the wall meets the floor or ceiling. You can also use this sealant around outlet and switch boxes.

Add Green Glue Noiseproofing Sealant to your soundproofing project to reduce noise transmission beyond what you have already accomplished with the compound. The sealant increases STC (Sound Transmission Class) rating, which is necessary in LEED certified facilities. Additionally, it is non-hazardous, has practically no odor, and it resists drying out or cracking with age. Having been independently tested by Underwriters Laboratories for fire safety and environmental impact, Green Glue Noiseproofing Sealant lives up to expectations.

Application Considerations:

• Leave a 1/8″ to 1/4″ gap around your wall or ceiling drywall perimeter to fill with Noiseproofing Sealant.
• We do not recommend sealing gaps of 5/8” or more with the sealant. It will not cure properly in large gaps.
  • For large gaps deeper than an inch, consider using backer rod to fill the gap before applying Sealant.
• The sealant is an acoustical seal. Do not use this sealant as a water seal or use it in exterior applications. Also, do not use the sealant to seal around pipes or plumbing.
• Finishing – after you have applied the sealant, cover it with standard finishing materials such as mudding and taping.
