Green Glue installation is fast and dispenses with very little effort. No measuring or troweling is necessary.Use a standard (32oz) quart size caulk gun to apply. Green Glue will not flow off the board during installation. Application time is about 20-30 seconds per tube. It is not necessary to have complete coverage to obtain excellent results.

Important Application Tips:

Green Glue is Sticky: There is nothing harmful about Green Glue, but it is important to warn your installers that it can be tough to clean up, especially after it has dried. Take precautions such as drop cloths and latex gloves when using Green Glue. Take care to remove the Green Glue from unwanted surfaces before it dries. Products that clean well are Avon Skin So Soft Bath Oil©, as well as citrus based solvents and cleaners such as Goof-Off©.

Green Glue Smell: Green Glue has a very slight smell. In the same way that you can smell paint while you are painting a room, you will be able to smell Green Glue as you are applying it. Most installers aren’t bothered by the smell, but it is nevertheless important to keep the room well ventilated to prevent a build-up of smell. Cold temperatures or high humidity will slow drying. Smell will not linger on furniture, clothing or carpeting. Like paint, once dry, the smell will fade. Keep the spent tubes in a plastic bag and remove them regularly.

Recommended Green Glue Coverage: The ideal coverage should be uniform throughout the sheet using 2 tubes. Applying 1 tube of Green Glue per 4’ x 8’ sheet will deliver about 70% of the performance of 2 tubes. Three tubes is optimal per 4’ x 8’ sheet will improve low-frequency performance around the primary resonance. We do not recommend using more than 3 tubes per sheet. If you use too much Green Glue, performance will decline.

Green Glue Drying Time: After applying Green Glue, do not let dry. Apply Green Glue within 15 minutes. Drywall sheets must be screwed together while the material is still wet. Allow Green Glue 30 days of drying time for optimal sound isolation performance. Because it needs to dry, Green Glue must be allowed 7 to 10 days drying time before sound isolation will start to improve. High humidity, cold temperatures and multiple drywall layers could slow the drying time considerably

STEP 1:
	Hang the first layer of drywall - After hanging the first layer of drywall, it is recommended that you seal the seams between sheets. This can be done with either acoustical sealant or drywall mud. If using acoustical sealant, take care not to use a bead so large that it protrudes outside the plane of the drywall, preventing the second layer from sitting flat. If speed is an issue, you can omit this step and seal the perimeter after the last sheet of drywall is installed.
STEP 2:
	Cut the end of the tube as shown in top left image.  Screw on separate nozzle and cut end leaving an opening of 3/8” or more. A larger tip opening can be used to speed application without concern for performance.
STEP 3:
	Apply Green Glue to the second sheet of drywall on a clean, flat surface. Placing the drywall on saw horses will help prevent the board from getting damaged or dirty from laying it on the floor. Apply the glue in large beads in a random pattern across the entire board. Leave a 2-3” border with no Green Glue around the edge of the board. This will allow for better handling of the board. Use 2 tubes per 4’x8’ sheet. (1 tube gives about 70% of the benefit of 2 tubes).
STEP 4:
	After applying Green Glue to the back of the second layer, raise the board into position, press the board against the wall or ceiling, and fasten in place using appropriate screws. The Green Glue will squeeze into a thin layer (about 0.5 mm). The second layer must be hung and screwed within 15 minutes to prevent Green Glue from drying before it is in place. Typical screw spacing is 16” oc for walls and 12” oc for ceilings, but be sure to follow all appropriate local building codes regarding screw type and spacing. Use our Green Glue Noiseproofing Sealant to seal cracks and seams paying special attention to the crack where the drywall meets the floor as this doesn’t get taped and mudded.
