Probably there are varieties out there that have solvents but haven’t been polymerized. Depending on the solvent, modified tung oil may not be food-safe like pure tung oil. Note that even products labeled as “pure” tung oil can be polymerized and have different drying and penetrating behavior than pure, unadulterated tung oil.

Oct 19, 2022 · "the mineral oil, which has the look I want" As you've probably already noticed to some degree, you won't get quite the same look that a completely colourless oil gives as you will using tung oil, even if it is a particularly light variety (although less variable than linseed the colour of different pressings of tung still varies quite a bit ...

Made a small plate out of hard maple. Sanded it down to 220 grit sandpaper. Finished with pure tung oil (100%, not the big box stuff) over the course of about a week, giving four coats. Let sit for two weeks inside (under fan, about 70 degrees), until it no longer 'smelled' like tung oil and there was no more seepage.

Re. the poly over undried oil leading to a splotchy finish, I haven't noticed that in practice. I've used varnish (multiple types) over freshly-applied oil many times and never had this problem. Experimentally I've even applied it immediately after the oil, with the same result — …

Apr 15, 2015 · Other than pure, "raw" tung oil there are some modified versions (partially polymerised to improve drying time). Additionally care must be taken to distinguish between actual tung oils and a "tung oil finish" which may contain no tung oil at all; in fact these can be little different to products sold under the name Danish oil (that is: a blend ...

Nov 16, 2017 · The exact type of tung finish aside, if you want protection from water my advice is always to go with varnish instead of oil (even tung oil which is supposedly much more waterproof than BLO and other finishing oils). Varnishes are harder, tougher, provide much greater wear- and water-resistance, and, not a minor point, they work faster. –

Apr 17, 2019 · Tung oil is, relatively speaking, a poor moisture seal. All straight oils are. Tung has this great rep for being waterproof but it tends to be exaggerated, and when used straight as it is normally applied these days it provides little meaningful protection.

Tung oil does not "dry" by evaporation (like water or organic solvents). It cures by polymerization. The curing process is facilitated by oxygen. Tung oil on the wood surface therefore polymerizes relatively quickly compared to tung oil that has penetrated into the wood, where it is in a relatively oxygen-poor environment.

Jan 11, 2021 · It takes quite a bit of "Tung" oil to finally create a decent top coat that will handle moisture. Whether you use multi coats of "Tung Oil" or an oil and top coat finish, you can always add a couple coats of Howard's Feed'n wax as a top coat to add extra protection and just plain add a bit of depth to the finish. Hope this helps in some way.
