5. Using cellulose tape, mask the area directly above and below the grid break. The break area
should be at the center of the mask.
6. NOTE: If the brown layer is not broken or missing, apply only the silver grid repair compound to
the break.
NOTE: If both the brown and silver layers of the grid are broken or missing, apply a coating of
the brown touch-up paint across the break in the grid line first. Do not overlap the silver grid line
with the brown paint . Several applications may be necessary to achieve a color match.
NOTE: Extend the silver repair coating at least 6.35 mm (0.25 inch) on both sides of the break
area.
NOTE: Allow at least five minutes of drying time between applications.
Apply the repair coating to the grid break area in several smooth, continuous strokes.
Apply three applications of the grid repair compound.
7. After five minutes or after the repair area has dried completely, remove the mask.
8. CAUTION: Be careful not to damage the grid line with the razor blade. If this occurs,
additional repair may be necessary.
Remove any excess repair compound above or below the grid line with a razor blade.
9. NOTE: The repair coating will air-dry in approximately one minute and can be energized within
three minutes.
NOTE: Optimum adhesion occurs after approximately 24 hours.
After optimum hardness is achieved, clean the repaired area with a non-alcohol based window
cleaner.
