Green Glue Noiseproofing Sealant is used to fill gaps and joints where the wall meets the floor or ceiling, and where two walls meet. It can also be used around outlet and switch boxes. Easy to install and paintable once it dries completely (48 hours), Green Glue Noiseproofing Sealant is the finishing touch needed after installing Green Glue Noiseproofing Compound.
Adding Green Glue Noiseproofing Sealant to your soundproofing project reduces noise transmission beyond what is 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.
It is recommended a 1/8 to 1/4” (0.3 to 0.6 cm) gap be left around the perimeter of your wall or ceiling drywall to fill with Noiseproofing Sealant.
Sealing gaps of 5/8” or more with the Sealant is not recommended, as it will not cure properly in large gaps. Instead, for excessively large gaps deeper than an inch consider using backer rod to fill the gap before applying Sealant.
The sealant is only intended to be an acoustical seal; it is not intended to be a water seal or to be used in exterior applications. do not use the sealant to seal around pipes or plumbing.
Finishing - after the sealant is applied cover with standard finishing materials such as mudding and taping.
