Solving Cracking & Flaking Problemsnxtlm2021-05-17T09:07:58-04:00
INTERIOR 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 later stages, flaking.
- Use of 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 a primer.
- Excessive hardening and embrittlement of alkyd paint as the paint job ages.
- 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.
