OVERPAINTING

Sikaflex-291 can be best painted after formation of a skin. Painting could be improved by treating the joint surface with Sika Aktivator-100 or Sika Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions.
