Cracking/Flaking

The splitting of a dry paint film through at least one, which will lead to a complete failure of the paint. In its early stages, 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 too 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 or power washer. Then, prime and repaint with a quality exterior latex paint.
