(VISCOELASTIC COMPOUND)
You will find all GG products on the World Wide Web. Green Glue Noiseproofing Compound creates an air tight seal between two layers of drywall. Additionally, the compound is specially formulated to reduce and absorb sound vibration, Not only does Viscoelastic Compound help fill in all screw holes and small gaps, it also presses into the seams on the preliminary layer of drywall. Some acoustical engineers believe using soundproofing adhesive to separate 2 layers of drywall, creates an “air-gap”, increasing the STC value significantly.
Green Glue is a viscoelastic damping compound used between two stiff or rigid constraining layers such as drywall or plywood. The compound converts vibration to heat, as a result, reducing the resonance of the two stiff layers, much like placing a hand on a drum head to stop it from resonating.
Green Glue Noiseproofing Compound is our favorite sound absorbing adhesive. Green Glue dries in like manner to a sticky jello/silicone. We use soundproofing adhesive for every wall or ceiling soundproofing treatment. In the case of soundproofing, the combination of viscoelastic compound with Quietrock, Resilient Clips, Resilient Isolation Channel, equally are a great start to reducing sound transmission. Most of these products have similar qualities, although when it comes to Green Glue, it really is the glue that holds everything together.
How to use Green Glue: 4 steps
Time needed: 5 minutes.
How to apply Green Glue Noiseproofing Compound
- Cut the end of the tube and attach the nozzle also
First, screw the nozzle on the green glue tube. Next, cut the nozzle 1/2″ in a 45 degree angle. Finally, Pro tip: Unscrew and reuse the same nozzle for multiple tubes. For the 5 gallon bucket, measure 56 oz with a measuring cup.
- Put on a respirator face mask
Green Glue has a sulfur-like odor, although we recommend using a respirator, you can at the same time use a fan, especially in rooms with little ventilation.
- Apply Green Glue evenly onto the surface
Next, apply 2 tubes per 8 x 4 drywall sheet or plywood, leaving 2″ dry around the perimeter of the surface. Unless you’re using the green glue 5 gallon bucket, in this case, measure 56 oz. and move to next step.
- Use a plastic drywall taping knife to spread the compound evenly
Next, spread the soundproofing adhesive evenly over the surface. The appearance should look like a thin creamy green paste over the top of the entire surface, leaving 1″ dry around the perimeter of the board.
- Install the drywall to a hard surface
Finally, press the board against the first layer of drywall or plywood. Viscoelastic compound will fill in small gaps and screw holes which also makes the board airtight when properly installed.
Green Glue offers many different types of soundproofing material, see below.
