Which is the best varnish for Cabreuva flooring (Santos Mahogany)?

Q: Which is the best varnish for Cabreuva flooring / Santos Mahogany? We tried some different varnishes, but it could not dry.

A: These exotics can be quite a challenge given the oils or what might be referred to as ‘extractives’. A water borne finish may be your best choice because you would avoid any cross activity happening between the main solvent in oil modified which is mineral spirits and those naturally occurring extractives. You could use a water borne sealer first and water borne top coats afterward. I would highly recommend Poloplaz 202 which is a commercial grade finish without the risks of having to add or handle a cross linker.
