Preparation: All surfaces must be clean, dry and structurally sound. Surfaces must be free of dirt, dust, mud, oil film, snow, ice, standing water, and other foreign materials that may affect adhesion prior to using adhesive. Concrete or block walls must be well cured, dry, and free of any release agents. Special Note: Actual cure times may vary depending upon ambient conditions at the time of application.
General Construction Use
Pre-cut and fit all materials before applying adhesive. All materials should be glued together within 15-20 minutes after adhesive application. If work is delayed, removeexcess adhesive and begin again.
Paneling and Foamboard Panels
Apply continuous beads of adhesive to studs or furring strips (wood or metal). For wall surfaces, apply continuous parallel beads of adhesive 12-16 inches O.C. Position panel and press firmly in place. Use finishing nails or mechanical fasteners along top and bottom edges to hold panels in place. Temporary blocking of panels may be necessary until adhesive sets or if panels show evidence of warping.
Apply adhesive in same manner as for paneling. Permanent mechanical fasteners are required 16 inches O.C. around perimeter of panels. Field fasteners may be required if gypsum board shows evidence of warping. NOTE: Field fasteners are required 24 inches O.C. for all ceiling applications in addition to perimeter fasteners when using adhesives. For Manufactured Housing applications, follow prescribed fabrication procedure and fastening schedules outlined in the respective manuals according to ASTM E72 specifications.

Avoid eye contact. Do not take internally. If swallowed, may cause abdominal discomfort. Keep From Freezing.
