Sikkens: the right color

Symptoms

Contamination of the substrate (e.g. silicone, grease, wax) causes surface defects . This results in areas where the coating does not cover the substrate.

Cause

  • Often a silicone or wax contamination
  • Surface not cleaned sufficiently before application
  • When spray-applied: poor functioning of oil/water separator
  • Open pored timber

Solution

Clean surface with a suitable emulsion cleaner. Paint with an opaque finish, to which an anti-crater additive  can be added. Prime open pored timber with a good filling coat.
