Sikkens: the right color

Symptoms

A craquelé (crackle) effect appears, random cracks all over the surface

Cause

  • Paint system too brittle for the substrate
  • Layers applied too thickly
  • Emulsion paints applied at too low temperature and/or too high relative humidity
  • Applied product can not follow the movements of the substrate
  • Pollution in between layers

Solution

Paint layers that are not sound should be removed. After the right pre-treatment, a new system should be applied. Touch up bare spots with [Alpha Dispersion Primer or equivalent]. Apply two complete coats of [Alpha Topcoat or equivalent].
