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 flage 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(R), DuPont 2610(R), Sherwin-Williams PSE 4600 and NP70(R) and Martin-Semour 5120,5130(R), 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.
