Quick Bits of Info

  1. Smell

    Green Glue Compound does have a slight smell, but it is less noticeable than paint and begins to fade within a couple hours.

  2. Not Really an Adhesive

    While Green Glue Compound is sticky, it is not an adhesive and should never be used without fasteners.

  3. Cleanup

    Green Glue Compound can be washed off your hands, tools, or other objects using soap and water. Pumice soap is recommended.

  4. Messiness

    Responsible application will lead to no mess. Green Glue Compound is thick enough to not run off the drywall.

  5. Coverage Requirements

    No specific coverage pattern is necessary to ensure excellent results. Apply at least semi-evenly for successful application.

  6. Larger Nozzle Opening

    A larger opening on the nozzle (1/2″) will speed up application without affecting the performance of the Green Glue Compound.

Preparing and Loading Our Dispensing Gun

  • Cut End Of Nozzle

    Using a razor knife, cut a 3/8″ to 1/2″ bead off the end of the nozzle.

  • Dip Nozzle Cone Into Compound

    Submerge the orange cone nozzle about 2″ into the Compound. Eliminate mess by keeping the barrel of the dispensing gun from touching the Compound.

  • Press Recoil Thumb Plate and Pull T-Lever

    Press the recoil thumb plate down while holding the gun firmly in your hand, and pull back on the recoil T-lever, drawing Green Glue Compound into the dispensing gun, until full.

    QUICK TIP:  If the Green Glue Compound does not seem to be loading into the dispensing gun very well then cut a larger bead opening on your nozzle cap.

Different Levels of Coverage

  • Light Coverage

    1 tube per 4′ x 8′ sheet

    No increase in low frequency isolation. Decent gains in mid to high frequencies.

  • Standard Coverage

    2 tubes per 4′ x 8′ sheet

    Consistent gains from low to high frequencies.

  • Heavy Coverage

    3 tubes per 4′ x 8′ sheet

    No increase in mid to high frequencies. 50% gain in low frequencies.

Four Steps to a Successful Green Glue Compound Installation

  • Dispense the Green Glue Compound

    With your drywall on the floor or leaning against a wall, apply the Compound from your caulking gun in a random pattern. Be sure to leave a 2″ perimeter so you can hold the drywall while lifting it into place.

    GOOD IDEA:  Have a bucket of water for the dispensing gun. Green Glue Compound will cure very slowly if kept wet so the dispensing gun can be left submerged in water for days.

  • Place Drywall Against Wall

    Once the Compound is applied, lift it into place against the wall or ceiling. It is important to accurately mount each panel the first time without sliding it around.

  • Screw Drywall to Framing

    Drill each sheet of drywall into place entirely before installing the next sheet. The second layer of drywall should be fully attached to the studs with the same screw pattern as the first layer.

  • Seal Your Wall

    Offset the seams of the second layer from the first layer to avoid having to seal the first layer with caulk.

    Once the topmost layer of drywall is attached, seal thoroughly using Green Glue Sealant or a comparable caulk. Tape and mud your seams as you would normally and prepare for your wall finishing.

Other Useful Tips:

  • We strongly recommend the use of our Green Glue Dispensing Gun for quick and accurate application.

  • A 1/8″ notched trowel can be used, but is more messy and difficult to apply the correct amount of Green Glue Compound per square foot.

  • There is no correct pattern to follow when applying Green Glue Compound. Consistency in ounces per square foot is the only requirement.

  • You can use any thickness of drywall with Green Glue Compound. The more mass, the better the performance in low frequencies.

  • Leave a 2″ border along the drywall perimeter for easier handling and room for the Green Glue Compound to spread on compression.

  • Sealing the wall is crucial to the performance of any sound assembly. Unsealed gaps can transfer significant amounts of sound.

  • The first layer of drywall should be attached using 1-1/4″ drywall screws and the second layer with 1-5/8″ or 1-7/8″ drywall screws.

  • Green Glue Compound must compress between layers to work properly. Completely fasten each sheet within 15 minutes of application.

Cleaning the Dispensing Gun

Green Glue Compound is a very sticky product that becomes incredibly difficult to clean once it has cured. For this reason, it is crucial to fully clean the dispensing gun after each use. Otherwise the dispensing gun will become inoperable. Cleaning involves disassembling the dispensing gun and using water pressure to remove all Green Glue Compound residue from the cone nozzle, barrel, and inner workings of the tool.
