Installation

DUOTACK SPF HFO Adhesive should be applied to approved substrates free of oil, grease and other contaminants. To adhere SENTINEL HFB (Heavy Fleece Back) membranes, DUOTACK SPF HFO Adhesive should be applied using a spatter application. Apply the adhesive to 55-65% of the substrate, which yields an approximate coverage rate of 30 squares per kit. The membrane is then rolled and broomed into place prior to curing.

To adhere insulation and coverboard, DUOTACK SPF HFO Adhesive should be applied in a ribbon application at 2.5 in wide beads, spaced at 12 in apart. Maximum spacing for
ribbons is 12 in on center, which yields approximately 35 squares per kit. Spacing 4 in or 6 in on center may be used on the perimeter and in corners. Decreased spacing of the ribbons will result in reduced coverage rates.

Product open time can range from 1-10 minutes depending on ambient air and substrate temperatures. The ambient air temperature should be between 40-­100°F (5-38°C).

Refer to the SENTINEL PVC Technical Manual for additional application guidelines.
