How to Apply Glue Green | Step-by-Step Guide
For best performance it is recommended that you use two tubes of green glue per sheet of 4×8′ drywall.
STEP 1 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 green glue dispensing gun or standard 28oz 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 Sealant 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 have distributed product evenly across the drywall.
STEP 3 Once the first tube is empty, discard the cartridge and replace with the prepared second tube and dispense onto the panel. Finishing or mudding the first layer of drywall is not necessary if you stagger the second layer of drywall to cover any seams (recommended method).
Does Green Glue Noise Proofing Compound Really Work & Is It Worth The Money?
If you’ve ever soundproofed ANYTHING, there’s no way you wouldn’t have heard of Green Glue, even if you haven’t tried it. It’s the most popular adhesive for soundproofing applications.
Does Green Glue really work as a soundproofing solution?
The short answer is yes, Green Glue does work very well as a noise dampener- especially for low-frequency sounds and is worth the cost. However, it’s important to remember that Green Glue is just one of the MANY important steps you need to take while soundproofing and if you don’t take care of those other aspects, you might be disappointed with the results.
How Does Green Glue Work? Green Glue stops the vibration of the material on which it is applied. This is what stops sound from getting transmitted.
Simply put, Green Glue is a damping compound that helps stop sound vibrations from traveling between two rigid layers of the wall.
Sound travels through any given medium by vibrating its molecules, which transmit sound.
Some mediums are more conducive to sound transmission than others- and in order to soundproof ANYTHING, all we’ve got to do is mimic the properties of those materials that do not allow sound to pass easily.
Basically, it all comes back to stopping sound vibrations. There are many ways of doing this- such as:
- Adding a damping layer- Green Glue
- Adding mass
- Decoupling walls such that they aren’t in direct contact and do not transmit sound easily
The act of resisting the shear force creates heat at a microscopic level which gets dissipated inside the wall- in line with an important principle of thermodynamics:
“Energy cannot be created or destroyed, it can only be changed from one form to another.“ – Albert Einstein.
