Construction Adhesives

Application Guidelines

Application Temperature:

Over 50°F and below 90°F for adhesive and substrates (can be applied down to 0°F, but reduces drying speed)

Service Temperature Range:

-40°F to 220°F

Working Time:

20 minutes at 70°F

Prep:

Surfaces must be 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, high spots, dust, oil, and grease. Cut and pre-fit all panels. Lay panels flat and let them acclimate to room temperature 24 hours before installing. Note: Best results when adhesive and materials are used above 50°F. For Pouches: Hold pouch on end and rest on working surface. Snip the top tie off clip then squeeze adhesive onto the back of the panel. One pouch covers one 4’ x 8’ panel. A plastic putty knife can be used to push out excess adhesive stuck in the pouch.

Application:

Spread adhesive over entire back of panel, using a V-notch trowel with notches 3/16” wide x 1/4” deep x 11/16” center to center (or 1/2” space) or 3/16" wide x 1/4" deep x 1/2’’ center to center (or 5/16’’ space), staying one inch away from all edges. For best results, trowel adhesive in vertical stripes to aid in more consistent curing. Keep trowel notches clean and free of adhesive build-up to ensure proper application. 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 channel 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 panels for fasteners, pipes or conduits should be oversized to allow for natural movement of the panel. Spread no more adhesive than can be installed in 20 minutes or less.

Cleanup:

It is important to cleanup adhesive immediately while still wet. To clean adhesive from panel, tools and hands while wet, use isopropyl alcohol or acetone as a solvent. Once adhesive has cured, it can be extremely difficult to remove. Follow solvent vendor’s precautions.

Limitations:

Before installation, it is important to wipe down all metals with acetone if an oily residue is present, as this can deter adhesion. When bonding two non-porous substrates together, particularly in low humidity climates, it is recommended to lightly mist the wall substrate with water just before applying panel. Panels that do not lay flat or are heavier in weight may require at least 24 hours of blocking and bracing or permanent mechanical fasteners. If applying adhesive over painted, plastered, or seal coated surfaces, please contact Technical Service at 1.800.347.4583.
