Basic Use

Millennium Hurricane Force® 1-Part Flashing Adhesive is specially formulated for use as a vertical grade flashing adhesive for bonding approved base sheets, vapor retarders and membranes for low slope roof applications. Millennium Hurricane Force® 1-Part Flashing Adhesive can also be used to seal head laps in modified bitumen roof membranes.

Millennium Hurricane Force® 1-Part Flashing Adhesive forms a strong bond to most substrates and does not soften or damage the membrane.

Approved Substrates
  • Concrete
  • Cinder and masonry block
  • Base sheets (sanded or
  • granule surfaced)
  • Plywood
  • Metal
  • Fiberglass insulation
  • Polyisocyanurate insulation
  • Perlite insulation
  • Wood fiber insulation
  • Polystirene (XPS, EPS)
  • Gypsum Cover board
  • High density polyisocyanurate cover board

Approved Membranes

  • SBS modified bitumen base sheets
  • SBS modified bitumen mineral surfaced cap sheets
  • Do not apply to wet or damp surfaces. This includes primers.
  • Allow solvent based primers to completely dry before using the adhesive.
  • Do not apply when surface temperatures are below 40°F (4°C).
Application Method

1. Ensure that the substrate is suitable for bonding and is clean, dry, and free of defects.

2. Apply Hurricane Force® 1-Part Flashing Adhesive with a 1/4” (0.6 cm) notched trowel directly to the backside of the flashing membrane (as shown) or to the bonding substrate.

3. Embed the flashing membrane into the freshly applied adhesive. Do not allow the adhesive to skin over. Apply pressure across the entire membrane surface to ensure full contact with the adhesive removing all wrinkles and air pockets.

4. A continuous bleed-out of adhesive should be present along all membrane side laps and tie-ins.

5. For multi-layer flashing applications repeat steps 2-4.

Surface Preparation

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