Common Causes of Paint Cracks

  • Substrate movement — Settling foundations, temperature/humidity changes cause hairline or wider cracks.
  • Poor preparation — Painting over unstable old layers, no primer, or dirty surfaces.
  • Moisture issues — Damp walls, leaks, or condensation leading to bubbling and cracking.
  • Wrong paint type — Using inflexible paint on surfaces that expand/contract.
  • Age & wear — Natural breakdown of old paint over years.

Step-by-Step Guide to Fixing Paint Cracks

  1. Assess & clean — Identify crack type (hairline vs structural); clean area of dust/loose paint.
  2. Open & remove — Gently widen hairline cracks with scraper for better filler adhesion.
  3. Fill & level — Use flexible filler (interior) or exterior caulk; apply in layers, let dry, sand smooth.
  4. Prime — Apply bonding primer over repaired area to seal and improve topcoat adhesion.
  5. Repaint — Match existing colour/sheen; apply 2 thin coats for even coverage.
  6. Prevent recurrence — Address underlying moisture/movement; use flexible paints in future.

Prevention Tips from Whitehouse

Always prime properly; choose elastic/flexible paints for high-movement areas; fix leaks promptly; ventilate interiors to control humidity. Whitehouse uses quality materials that resist cracking from the start.
