Finishing and tooling must be performed within the sealant’s tack-free time using soapy water. In the case of lubricants and other finishing agents, compatibility testing is required.

Sikaflex 221 allows overpainting once the skin has formed. The sealant should be fully cured before baking if baking is required.
