What is considered the best protective finish for wood?
Polyurethane Wood Finish
Wax, oil and varnish are three materials that will protect your furniture and that you can easily apply at home yourself. The three options will maintain the most "natural" aspect of the furniture, preserving the grain of the wood without adding big touches of colour, as paints, lacquers, etc.

Shellac – Shellac is a varnish made from the resin of the lac bug. It is a softer finish that is often recommended for lighter-colored woods. It is also better for areas with high moisture and frequent wear, as it dries much faster than polyurethane.

What wood finish is best for outdoors?
Epoxy finishes provide the most protection of all outdoor finishes, creating a thick, plastic-like, water-impermeable barrier on the surface of the wood.
