Window surround, replacing
When re-using an undamaged window, pull off the
surround beginning in the sleeve area. Scrape off
remaining material with a commercially available
glass scraper down to a few tenths of a millimeter. Do
not damage primer and ceramic layer when
performing this step.
- Replace window surround and install new cutting
thread.
Note:
The remaining material acts as the adhesive base for
the new adhesive sealant which has to be applied.
CAUTION!
Do not prime adhesive surfaces, do not activate
and do not treat with cleaning solution. Keep
adhesive surfaces clean from dirt and grease.
Exception: If adhesion is not done immediately after
cutting back, the residual adhesive must be activated
with activator D 181 801 A1.
- Apply adhesive all around to pre-coating and
window surround.
Width 6 - 7 mm
Height 11 - 13 mm (including pre-coating,
remaining material on window and window
flange).
