Installation

DUOTACK SPF ADHESIVE should be applied to approved substrates free of oil, grease and other contaminants.

Fleece-backed PVC Installation: To adhere SENTINEL HFB membranes, DUOTACK SPF ADHESIVE should be applied using a spatter application. Apply the adhesive at approximately 3,000 square ft per kit. The membrane is then rolled and broomed into place prior to curing.

Rigid Insulation and Coverboard Installation: Apply DUOTACK SPF ADHESIVE in a ribbon pattern. Ribbons should be 2.5 to 3.5 in wide and spaced a maximum of 12 in on center (O.C.) Applying ribbons at 12 in O.C. yields approximately 3,500 sq ft per kit. Once the adhesive has adequately cured, place the insulation/coverboard and walk into place. Product open time can vary depending on ambient air and substrate temperatures.

Because of the uneven surface of the remaining embedded aggregate, SOPRAROCK® was chosen knowing that this board would conform to the uneven surface much better than a rigid coverboard could. This idea spawned another....”why not use SOPRASMART® XP”; and allow one application step instead of two. The project was capped off with SOPRALENE® 180 FR GR, in COLPLY® Adhesive.
