The fast and dependable One Step™ applicators make applying Millennium Hurricane Force® Lap and Flashing Adhesive simple:
• Millennium One Step™ Battery Powered Applicator
• Millennium One Step™ Pneumatic Applicator

Application Method

1. With a utility knife, remove the molded tips at the groove from the One Step™ mixing head.

2. Attach a One Step™ mixing nozzle to the threaded mixing head.

3. Place the cartridge into the appropriate One Step™ applicator.

4. Dispense an initial amount of Millennium Hurricane Force® Lap and Flashing Adhesive into a waste container to ensure a proper mix, then diskard.

5. For lap adhesive Installation apply Millennium Hurricane Force® Lap and Flashing Adhesive in one continuous 3/4” - 1” (1.9 cm - 2.5 cm) wide bead down the center of the membrane’s selvage edge. As adhesive is applied immediately set membrane into wet adhesive.

6. For flashing installation apply the adhesive to the back side of the membrane or directly to the substrate in a ribbon pattern. Spread adhesive with a 1/4” (0.6 cm) notched or serrated trowel for full coverage applications. Immediately set flashing membrane in place.

7. For laps immediately roll with weighted roller to ensure positive contact between adhesive and membrane. For flashing immediately roll with a suitable hand roller.

8. Unused adhesive can be applied at a later date by simply plugging the cartridges (with provided half moon plugs) and using a new One Step™ mixing nozzle.
