Full-Cut Method Description
Note:
• 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.
Use only the full cut method, also known 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.
• Apply 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.
