| Cracking/Flaking: The splitting of a dry paint film
through at least one coat, which will lead to complete failure of the paint.
Early on, the problem appears as hairline cracks; later, flaking of paint chips
occurs.
Possible Cause:
Use of a lower quality paint that has inadequate adhesion and
flexibility.
Overthinning the paint or spreading it t(x) thin.
Poor surface preparation, especially when the paint is applied to bare wood
without priming.
Painting under cool or windy conditions that make latex paint dry too fast.
Solution: It may be possible to correct cracking that does not go
down to the substrate by removing the loose or flaking paint with a scraper or
wire brush, sanding to feather the edges, priming any bare spots and
repainting. If the cracking goes down to the substrate, remove all of the paint
by scraping, sanding and/or use of a heat gun; then prime and repaint with a
quality exterior latex paint.
