Basic Use

The adhesive is applied in a variable web spray pattern via a self-contained spray system. Product is applied full coverage to adhere Fleeceback and standard EPDM and TPO membranes to approved insulation, cover board, OSB etc. The adhesive must be applied to both the membrane and substrate to which it will be mated. Once dry the membrane can be mated to the substrate and brushed in.

Coverage Rates

• Coverage rate is 1000ft²/canister for finished two sided application when laminating smooth field membrane to board stock/substrate. Coverage rates may vary with fleece membrane.
• Coverage rate is 750ft²/canister for two sided vertical wall application when laminating smooth field membrane to wall substrate. Coverage rate for this application is decreased due to increased overlap of spray pattern for the vertical application.
• Coverage rates may be lower when used over irregular surfaces and will vary depending on roughness of membrane/substrate surfaces.

1. Shake adhesive canister for 30 seconds prior to use.
2. Attach spray gun to hose and then attach hose to adhesive canister. Open valve on canister and check connecting fittings for leaks. Once valve has been turned on, do not turn the valve off until the adhesive canister is completely empty or proper cleaning (see instructions below) is performed.
3. Bonding Adhesive can be applied at ambient temperature of 25°F and above. Adhesive canister temperature must be at least 70°F prior to use for the product to spray properly. Substrate must be clean, dry, and free of debris and contaminants.
4. Adjust the spray pattern/fan by slowly adjusting trigger lock to the desired pattern and locking when not in use.
5. Visually target the “Correct Amount of Adhesive” coverage pattern detailed in the image below. Typically spray with the trigger fully open, at a height of ~12 inches, and a rate ~1ft/sec to obtain “Correct Amount of Adhesive” spray pattern. Apply adhesive with proper overlap to ensure adequate adhesive coverage.
6. Apply Millennium Sprayable Single-Ply Bonding Adhesive in an even coat to deck substrate and membrane, keeping the spray tip approximately 12” (30.5 cm) away and perpendicular to the surface during spray. Avoid high thickness buildup.
7. For applications taking place in ambient temperature below 70°F, store adhesive canister in heated space and move to project area during application. Adhesive canisters must be kept warm on the jobsite. Dispense product from canister while it is still warm. Adhesive will begin to spit rather than spray when the adhesive in the canister is too cold. If this occurs, swap cold canister for warmer one and return cold canister to heated area. Before changing canister, close the valve on the canister and depressurize the hose. Remove the hose and attach to the new canister. Open valve and do a test spray.
8. Allow Millennium Sprayable Single-Ply Bonding Adhesive to flash-off until it does not transfer to finger when touched. Limit application to surfaces that will be covered with membrane the same day.
9. Follow OEM membrane manufacturer’s guidelines when laying membrane into adhesive.
