Construction Adhesives

Application Guidelines

Application Temperature:

Over 50°F and below 90°F for adhesive and substrates.

Service Temperature Range:

0°F to 120°F

Working Time:

20 minutes at 70°F.

Prep:

Surfaces must be dry and free of any material that may deter adhesion, including severe and thick amounts of drywall joint compound. Patch holes and depressions and remove any bumps or high spots, dust, oil, and grease. Concrete surfaces must be well cured and completely dry.

Application:

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). For best results, trowel adhesive in vertical stripes to aid in more consistent drying. 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.

Cleanup:

Tools and adhesive may be cleaned with water while the adhesive is wet. If dried, tools and adhesive may be cleaned with water/acetone/vinegar mixture. Follow solvent vendor’s precautions.

Limitations:

Do not bond two non-porous substrates together such as FRP, metal, plastic, foam board, sealed concrete, fiberglass face or mold resistant gypsum wallboard or any other non-porous surfaces. For installations bonding two non-porous substrates together use Titebond Advanced Polymer Panel Adhesive. For installations over treated plywood use Titebond Solvent Based FRP Adhesive or Advanced Polymer Panel Adhesive. The optimal trowel for best overall performance and coverage is a v-notch trowel, 3/16” wide x 1/4” deep, spaced 1/2” c.c. Trowels using dimensions other than the optimal size can be used, but they may affect working time and coverage.
