Can I put polyurethane over tung oil?
Woodworking Expert – Michael Dresdner: “Yes, I would put a coat or two of oil-based polyurethane on for more durability, and it is fully compatible over the dried tung oil (or linseed oil, or any other drying oil for that matter.) … There are still many varnish formulations that use tung oil.
Should you sand between coats of tung oil?
Oil finishes include boiled linseed oil, tung oil, and a mixture of varnish and one or both of these oils. All finishes that harden are film-building finishes. … You can create a fairly smooth oil finish by sanding between coats using very fine grit sandpaper (#320 grit or finer).
Can tung oil spontaneously combust?
Drying oils, especially linseed oil (raw or boiled), are the only finishing materials that spontaneously combust. … It’s not totally clear whether 100% tung oil can spontaneously combust, so treat it like it does. As linseed oil dries, it generates heat as a byproduct.
What is the best finish for outdoor wood?
Marine spar varnish is the best type for outdoor use. Its key ingredients are linseed oil (pressed from flax seeds) and alkyd resin (made by reacting linseed oil with alcohol and acid). The film is flexible enough to move with wood as it shrinks and swells with shifts in humidity.
How often does tung oil need to be reapplied?

How long does tung oil last outdoors?
Tung oil is a drying oil meaning that it will chemically react with oxygen to crosslink into a dry film (it won’t feel oily). This can take many days or even weeks, but that is not a concern.

Tung oil takes up to 48 hours to dry. Polyurethane dries faster than tung oil and takes only 12 hours to cure. Polyurethane sits on top of the wood to form a protective barrier that is watertight in only two coats. When considering tung oil versus polyurethane for wood floors, polyurethane wins the debate every time.
Is it better to oil or wax wood?
Wood Oil: Offering more durability than a wax polish, Wood oils are easy to work with, very easy to repair (sand down scratches then reapply) but they do have slower drying times. Wood Varnish: Forming a seal on the surface of the wood, varnishes are the strongest of all wood finishes.
