Green Glue Acoustical Sealant Tubes

There is some misconception on where Green Glue Sealant should be used and how much acoustical caulk is really required. In sound tests for products like Green Glue Compound and resilient sound clips, an acoustical caulk is used to seal each joint and the perimeter of the test wall. Some people interpret this as Green Glue Sealant is required between every joint and angle regardless of how the wall is finished. This is definitely not the case. If the wall is going to be taped and textured then the majority of the wall will already be sealed. You can still seal these joints and angles with Green Glue Sealant, but the improvement in performance will be minimal.

Please follow the guidelines below when using Green Glue Sealant:

Wall that will be finished (taped and textured): Use Green Glue Sealant along the floor to fill the gap between the bottom of the drywall and the floor and around outlet openings between the outlet box and the drywall. Most installation efforts will not require more effort than this.

Wall that will not be finished (i.e.- bare drywall): Use Green Glue Sealant along every joint and perimeter angle. As well as around each outlet opening in your walls and ceilings.

Floors: Caulk each joint of your sub-floor and then along the perimeter of the room. If your finished floor is attached mortar or glue then there is no need to seal the gaps in the sub-floor. If the gaps are unusually large then you will still want to fill them with a caulk before finishing the floors.

Bottom Plates: Follow these guidelines:

Bad: Sealant under frame only. Sound can easily enter and exit the wall cavities.	Good: A good start for remodeling jobs where you are adding drywall to an existing wall.	Very Good: Beads under drywall to keep sound from leaking into the cavity, and under frame for redundancy
