Application:
Using a caulking gun, apply adhesive as a series of vertical beads 10 inches apart (perimeter gluing is not recommended). Start the beads
approximately 1 inch from the panel edge. Immediately after applying the adhesive place the foam against the substrate and press firmly into
place to flatten out the adhesive. Be careful not to over press. Mechanical fasteners must be used and kept in place until the adhesive is fully
cured. Cure time will vary depending on the porosity of the material used, the humidity and the temperature at time of application. Low
temperatures and high humidity will increase the amount of time required for the adhesive to dry. Bracing is recommended until adhesive is cured.
The adhesive must be fully cured before it can be exposed to elevated temperatures.
Drywall application over foam insulation:
Apply adhesive as outlined above. Position drywall, align and press firmly into place. Nail panel to underlying studs or strapping around entire
perimeter. It is recommended to brace the center or field of the panels for at least 24 hours. Mechanical fasteners must be used and kept in place
until adhesive is fully cured. Furring strips are recommended on concrete walls
Clean-up:
Clean tools and uncured adhesive residue immediately with water. Cured adhesive may be carefully cut away with a sharp-edged tool.
PROTECT FROM FREEZING. For best results, store at 70° ± 5°F in a cool, dry place. Store away from heat, flame and sparks. Take
unwanted product to an approved household hazardous waste transfer facility. Hardened material may be disposed of with trash.

The information and recommendations contained herein are based on our research and are believed to be accurate, but no warranty, express or
implied, is made or should be inferred. Henkel recommends purchasers/users should test the products to determine acceptable quality and
suitability for the intended use. All adhesive/sealant applications should be tested under simulated or actual end use conditions to ensure the
adhesive/sealant meets or exceeds all required project specifications. Since assembly conditions may be critical to adhesive/sealant
performance, it is also recommended that testing be performed on specimens assembled under simulated or actual production conditions.
Nothing contained herein shall be construed to imply the nonexistence of any relevant patents or to constitute a permission, inducement or
recommendation to practice any invention covered by any patent, without authority from the owner of the patent.
