Use only the full cut method, also known in the field as full strip method, when installing windows.
This method contains 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.
| • | If the pinch-weld flanging happens with corrosion or needs to be repaired or to replace metal plate, the pinch-weld flanging must be finely trimmed to make only bottom paint to appear on the clean 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. Materials such as BASF DE15, DuPont 2610, Sherwin-Williams PSE 4600 and NP70 and Martin-Semour 5120 and 5130 PPG DP90LF
SPIES/HECKER 3688/8590 - 3688/5150 - 4070/5090 STANDOX 11158/13320 |
| • | 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. Wait 10 minutes for the primer to dry. |
