Step1
Tap your GG tube on a hard surface to bring compound away from the tip and prevent dripping. Cut a ¼ inch hole in the tip of the rube with a utility knife. Screw nozzle tightly over the tip of the tube and cut a ¼ inch hole in the tip of the nozzle. Place the tube in a standard 28 ounces caulk gun to prepare for installation.
Step 2
With the first layer of drywall already installed, as per local building codes, apply Green Glue Noiseproofing Compound to the back of the second layer drywall by pulling the trigger to dispense the product from the tube. Leave a 2 to 3 inch border around the panel to allow for handling. The application pattern does not matter so long as you’ve distributed product evenly across the drywall. For best performance it is recommended that you use two tubes of compound on each 4x8 foot drywall panel.
Step 4
Within 15 minutes of applying Green Glue to drywall, fasten the panel to the first layer of drywall, following local building codes. Leave a ¼ inch gap along the top and bottom of the wall to allow for sealing. Continue with this process until you have applied Green Glue to all desired drywall panels.
