Cracking
- Flaking: The splitting of a dry paint film through
at least one coat as a result of aging, which ultimately
will lead to complete failure of the paint. In its early
stages, the problem appears as hairline cracks; in its
later stages, flaking occurs.
Possible Causes:
Use of a lower quality paint that has inadequate adhesion
and flexibility.
Over thinning or overspreading the paint.
Inadequate surface preparation, or applying the paint to
bare wood without first applying primer.
Excessive hardening and embrittlement of alkyd paint as
the paint job ages.
Solution:
Remove loose and flaking paint with a scraper or wire
brush, sanding the surface and feathering the edges. If
the flaking occurs in multiple layers of paint, use of a
filler may be necessary. Prime bare wood areas before
repainting. Use of a top quality primer and top coat
should prevent a recurrence of the problem. |
