Full-Cut Method Description

Use only the full cut method also know as in the field as Full Strip Method when installing windows.

This method includes the following:

• The replacement of a majority of the urethane adhesive bead remove all but approximately 2 mm (3/64 in) of the existing bead of urethane adhesive from the pinch-weld flange.
• Applying pinch-weld primer to any exposed painted areas on the pinch-weld flange.

  No mounds or loose pieces of urethane adhesive should remain on the pinch-weld flange. Do not remove all traces of urethane adhesive.

Important: 

• If corrosion of the pinch-weld flange is present, or if sheet metal repairs or replacements are required, refinish the pinch-weld flange in order to present a clean, primer-only surface.
• If paint repairs are required, mask the flange bonding area, prior to applying the color coat, in order to provide a clean, primer-only surface.
• Appropriate materials for these primer applications are typically 2 component catalyzed products. Use materials such as BASF DE15®, DuPont 2610®, Sherwin- Williams PSE 4600 and NP70® and Martin-Semour 5120,5130®, PPG DP90LF SPIES/ HECKER 3688/8590 - 3688/5150-4070/5090 STANDOX 11158/13320 - 14653/14980 products are approved for this application. Follow the manufacturer's directions for the mix, the application, and the drying times.
• After repairing the opening as indicated, shake the pinch-weld primer black #3 well. Using a new dauber, apply the primer to the primed surface of the flange in the bonding area. Allow the primer to dry for 10 minutes.
