Note: Sikaflex® - 291i can be painted over with most popular 2-component coating systems. The varnish compatibility has to be checked previously under production conditions. If the varnish will be burned-in, the sealant should be fully cured. Since the elasticity of the coating is less than that of the adhesive / sealant material, there may be cracks in the lacquer joints. PVC-based varnishes and varnishes, which dry by oxidation (oil varnishes and varnishes with alkyd resin) are not suitable for overcoatings.
