Each tube of our Sealant typically provides 40-80 linear feet (12-24 m) of coverage, depending on the size of the hole cut in the nozzle. In many cases, you will only need a tube or two to complete a project. A good rule of thumb is a 6:1 ratio between Compound and Sealant.

No, the Sealant is not intended to be used as a fire blocking material.

No, the Sealant is only intended to be an acoustical seal and is not to be used as a water seal or in exterior applications.

Typically, after Sealant is applied, you will “mud and tape” the final joints as normal. For decoupled walls choose construction materials designed to finish with slight movement, fiberglass mesh tape is often used.

For best results, follow the instructions on the Noiseproofing Sealant Installation Guide. Additional resources and video can be found on the Noiseproofing Sealant page.

We recommend leaving a 3/8 in (0.9 cm) gap around the perimeter of your wall or ceiling drywall to fill with the Sealant. We do not suggest sealing gaps of 5/8 in (1.58 cm) or more with the sealant 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.

We recommend that you allow the Sealant to dry for 48 hours before finishing or painting.

We do not recommend using the Green Glue Noiseproofing Sealant on exterior applications, around exterior windows, around pipes, in contact with copper materials, or for joints with significant movement such as floating floors. For more installation information, visit Noiseproofing Sealant.

The Sealant is off-white.

If dispensing the Sealant from tubes, you will need a standard 32-oz caulking gun (which can be found at many hardware or DIY stores) for application.

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 to fill the gap between the boxes and the drywall.
