Titebond GREENchoice Fast Grab FRP Construction Adhesive is a professional-strength LEED v4 Compliant adhesive specifically formulated for the installation of FRP (fiber-reinforced plastic) panels over most porous surfaces. Its fast grab and bonding power greatly reduce the need for extended bracing.
Cut and pre-fit all panels. Lay fiberglass panels flat and let them acclimate to room temperature 24 hours before installing. Note: Do not use when temperature, adhesive or materials are below 50°F. SPREAD ADHESIVE OVER ENTIRE BACK OF PANEL, USING A V-NOTCH TROWEL WITH NOTCHES 3/16” WIDE X 1/4” DEEP AND SPACED 1/2” CENTER TO CENTER (SEE DIAGRAM). Keep trowel notches clean and free of adhesive build-up to insure proper application. Immediately place panel against surface and press firmly over entire surface, working from the edge of the panel where molding is installed outwards to the open edge. Using a roller over the entire installed wall panel is also recommended. Note: Bracing may be required if walls or panels are not flat. Panels used in conjunction with channels moldings should NOT fit tightly into the moldings. Leave a small area in the molding for expansion and follow panel manufacturer’s recommendations. Any holes drilled through the FRP for fasteners, pipes or conduits should be oversized to allow for natural movement of the panel. When installing FRP panels over below grade concrete or block walls where moisture can penetrate from the back, attach furring strips with mechanical fasteners and Titebond Heavy Duty Construction Adhesive and then adhere a solid backing to the furring strips. Spread no more adhesive than can be installed in 20 minutes or less.
