Q-4 Why should the top of Finger Jointed Boards be Varnished?

A. A varnish finishing will not allow you to cut or chop directly on the wood br>top, but instead, will provide a superior protection to the wood without requiring periodic maintenance and subsequent re-applying. The varnish is especially strongly recommended whereas a lot of moisture is implied (such as bathroom vanity tops or the immediate vicinity of the kitchen sink). In this kind of situations, the mineral oil does not offer a full protection, so mold and black stains can eventually appear.

Ideally, the varnish should be applied with professional equipment operated in a special environment by knowledgeable personnel. Nevertheless, you can get comparable results at home, with only a paintbrush and a bit of skill. For countertop applications, water-based and polyurethane-based varnishes are the most common options.
