Use only the full cut method, also know as in the field as Full Strip Method, when installing windows.
This method includes the following:
- Remove all but approximately 2 mm (3/64 in) of the existing urethane adhesive bead from the pinch-weld flange.
- Apply pinch-weld primer to any exposed painted areas on the pinch-weld flange.
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 black #3
primer 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.
