Interior problem
Cracking/Flaking

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 Cause:

Use of a lower quality paint that has inadequate adhesion and flexibility.

Overthinning 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.
