SOLVING

CRACKING & FLAKING PROBLEMS

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.

POSSIBLE CAUSES:

  • 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.

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.
