Repaint or Investigate? Reading Signs of Coating Failure
Pro Painter USA Logo
MILWAUKEE WI, USA,

If paint has failed, repainting is only half the answer. The cause matters.

Key Takeaways

  • Peeling and blistering often point to moisture.
  • Fix the cause first.
  • Remove failed coating.
  • Use a system suited to the surface.

What failures can mean

Different failures mean different causes. Peeling can signal moisture, blisters trapped moisture, cracking movement and chalking surface breakdown.

  • Peeling can signal moisture or poor adhesion
  • Blisters can signal trapped moisture
  • Cracking can signal movement or age
  • Chalking is surface breakdown

What to do first

Find the moisture source. Test adhesion where needed.

  • Find the moisture source
  • Test adhesion where needed
  • Remove failed coating

Then repaint

Remove failed coating, clean and prime before repainting.

  • Prepare properly
  • Use a system suited to the substrate
  • Inspect after the first season

Different failures point to different causes. Blisters and peeling often relate to moisture, while cracking relates to movement or age. Treating the cause is what makes the new coating last.

Do not skip preparation. Removing failed coating and cleaning the surface matters as much as the new paint.
