SHRINKAGE OF COATINGS

Shrinkage of coatings due to solvent evaporation.

Causes
  • applying too thick layers of primer,
  • wrong amount of thinner (HS primers),
  • first layer of the primer is too thick,
  • too short a drying time,
  • insufficient drying of primer and putty layers,
  • too thin an insulation layer.
Prevention
  • make solvent test,
  • isolate with the use of twocomponent primer applied with several thin layers with keeping time for thinner evaporation,
  • avoid sanding topcoats.
Repair
