Green Glue Compound Five Gallon Pail

View our Product FAQ for answers to common questions about Green Glue Compound.

Damping compounds, like Green Glue Noiseproofing Compound, are relatively recent advancements in the sound isolation market. Green Glue Compound is a material that is applied between two layers of solid non-porous material, typically drywall or wood, in walls, ceilings, floors, isolation boxes, window plugs, and doors.

Green Glue Compound is most often applied from pails instead of tubes in larger projects covering more than 700 square feet of surface for faster application and lower cost per square foot. We strongly recommend the use our Green Glue Dispensing Gun when applying from the Green Glue 5 gallon pail for accurate and easy application. The cost for Green Glue Compound in pails is about 25 cents per square foot less than in tubes, assuming the project square footage divides well with the Green Glue pails.

WALLS

Green Glue Damping Compound can be used in most wall types including wood framing, steel stud framing in staggered stud walls, double stud walls, and walls with resilient clips or resilient channel installed. Walls with framing spaced 24" on center work best with Green Glue Compound. Walls with framing 16" on center will not respond as well to the Green Glue Compound because of the rigidity of the surface. Concrete and cinder block walls will not respond well to Green Glue Compound because they are too heavy and not resilient enough. The addition of Green Glue Compound to a standard 24" on center framed wall (applying Green Glue Compound to a new layer of drywall and fastening through the existing drywall into the framing) will increase the isolation level to a point where loud voices, television, and phones ringing are typically fully isolated.

CEILINGS

Ceilings are heavier and less resilient than walls, so they require more significant efforts to isolate sound transmission. The addition of Green Glue Compound to your ceiling between two layers of drywall will add some benefit, but often not enough to satisfy expectations, especially for performance relating to impact footfall noise. To gain the full benefits of Green Glue Compound in your ceiling, we recommend first installing a resilient sound clip system or resilient channel. Green Glue Compound, on a resilient system, will increase isolation for both impact footfall and airborne noise by about 7 IIC and 6 STC points.

FLOORS

Similar to ceilings, Green Glue Compound is best installed in resilient assemblies. If your ceiling below is suspended from resilient sound clips or resilient channel, then the Green Glue Compound will add about 7 IIC and 6 STC points to the assembly rating. Green Glue sealant is also valuable in floors when used beneath rubber underlayment or in layering beneath or above the GenieMat RST (layering uses layers of rigid materials such as plywood or Hardibacker).

ON STUDS OR JOISTS

Applying Green Glue Damping Compound directly to the studs or joists before the first layer of drywall will not help with the isolation performance of your assembly.

DISSIPATION OVER DISTANCE

The performance of a product is often only considered in terms of STC results from acoustic lab testing. Flanking sound transfer cannot be properly tested in an acoustics lab. If the material or structure has low damping, the sound vibrations can travel from material to material for great distances. If a structure has high damping, then the vibration is dissipated quickly and cannot travel throughout the structure with ease. Because of this, damping products like Green Glue Compound are vastly more crucial than lab tests show. Even in high STC assemblies (decoupled assemblies), the Green Glue Compound will have considerable value in reducing the strength of the vibrations that do pass through the assembly keeping those vibrations from traveling throughout the structure.

OUR DISPENSING GUN

We provide a much higher quality dispensing gun than the competition. A heavy duty dispenser with customizable thrust to make dispensing easier and faster, and an optimized nozzle for loading and dispensing Green Glue Compound.

Green Glue Compound is an extremely sticky product, but not an actual adhesive so screws still need to be used to secure the drywall or wood. Apply the Green Glue Compound from our Green Glue Dispensing Gun (cut a 1/2” opening in the provided nozzles) when using five gallon pails to the back of the new layer of drywall. The exact pattern in which you apply the Green Glue Compound is not important, but a level of consistency is required. The suggested application amount of two tubes per 32 square foot panel or one tube per 16 square feet should be followed as closely as possible.

NOTE: We recommend priming the dispenser before use with WD-40 and/or water. Once the gun is loading and dispensing the water with no problem, you can start loading Green Glue into the dispenser.

After the Green Glue Compound is applied to the new layer of drywall you will then fasten the layer with screws through the existing drywall and into the framing.

The performance of Green Glue Compound meets or exceeds other damping compounds available and easily exceeds the performance of nearly every pre-damped drywall. Green Glue Compound has been tested for STC, OITC, IIC, and is UL fire rated in multiple assemblies.
