Millennium One Step Foamable Adhesive®

Millennium One Step Foamable Adhesive® is designed for use as an adhesive for bonding approved roof insulations to a building’s structural roof deck, base sheets, other insulation boards, and smooth or properly prepared graveled built-up roof surfaces.

Millennium One Step Foamable Adhesive® eliminates the need for mechanical fasteners that can often cause damage to the roof deck, which can reduce the roof’s service life.

All work surfaces should be clean, dry, and free of dirt, dust, debris, oils, loose and/or embedded gravel, un-adhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven.

For applications over gravel surfaces apply Millennium Universal Primer prior to the application of Millennium One Step Foamable Adhesive®. For applications over fresh and/or non-oxidized asphalt, coal tar or plastic film membranes, Millennium Surface Treatment maybe required prior to the application of Millennium One Step Foamable Adhesive®.

1. Remove snap off tip from the One Step™ mixing head and keep for re-use.

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

3. Place the cartridge into the appropriate One Step™ applicator. Caution: Adhesive should be dispensed immediately after loading the cartridge into the dispensing tool to prevent adhesive from foaming and curing in the mixing tip.

4. Apply Millennium One Step Foamable Adhesive® directly to the substrate, using a ribbon pattern. Space 1/4” to 1/2” (0.6cm to 1.3cm) wide beads, 12” (30cm) o.c., to achieve proper coverage rates for insulation attachment. As adhesive is applied, immediately place insulation board into wet adhesive. Do not allow the adhesive to skin over. Eliminate uneven surfaces to ensure positive contact between the insulation board and substrate.

5. Un-used material can be applied at a later date simply removing the used static mixing tip, wiping the neck of the cartridge clean and plugging the cartridges with provided snap off tips.

6. Caution: Millennium One Step Foamable Adhesive® reacts quickly in warm, moist climates. Roofers must set insulation boards quickly in these conditions.
