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.

Only used brown once and it neither dried dark or light. It's in between a varnish pine and an oak. What I found was a tiny bit of varnish tinted with a stain and you can get a seamless seal with it, not visible to the eye. I only used it inside not out, so very little movement on the wood. Hope this helps.

Thank You. Seems daft to me advertising it as wood colour. Not helpful in the slightest. Why no colour chart showing it when dried or at least a full description? SVB take note
