Quick update: took the project by a local Rockler for advice, a few of the staff looked at it and everyone seemed to think I’d be fine, that my biggest mistake was probably leaving the coats to dry in direct sunlight – that probably kept the finish softer than it should have been.

They suggested leaving it to cure a few more days out of sun, then finish off with some Liberon wax polish and call it a day.

I know it’s hard without being able to see/touch something, but I still welcome anyone else’s thoughts/experiences/suggestions.

Thanks – R

I haven’t used it myself, but I know some people that have and it can be a bit of a pain. It should still cure, but it will take time. Try not touching it for a week and then see how it’s reacting. If it still hasn’t cured, then sanding may be the best bet.

I use T&T finishes on many smaller projects. Primarily use it for items where I want a minimum amount of film build, so the beauty of wood shines. My wife likes to call it a ‘naked’ wood finish, as it almost seems like bare polished wood without a finish.
My experience with varnish oil taught me that using 3+ coats to create a thick film requires much more cure time than label suggests. Here in AZ, initial 2 coats can be done about 8-12 hours apart. But I have to wait 36-48hrs between rest. If wood has any figure that behaves like end grain (absorbs oil), have seen T&T Varnish oil behave similar to straight BLO and weep oil (or stay gummy) for over a week. I would expect your 5 coats will need 2+ weeks to harden.
T&T Varnish Oil can develop a nice film finish if you have time to wait; but if I want project to have a durable film finish in less than a week, I apply 2-4 coats of Arm-R-Seal polyurethane (or spray lacquer).

Thanks so much for both these replies. Yes, your experience sounds consistent with what I’m finding – the first couple coats went on easily, as expected; it was the subsequent coats where I got into trouble and should have stopped.

I did hear back from T&T with some helpful suggestions as well. I like the way T&T products come out, and I like the lack of chemicals, but I was obviously a little naive about the drying process. In the future I’ll either use something else or budget adequate time for drying.

Thanks again for the feedback.

I’ve only noticed the tackiness when I haven’t sufficiently wiped the remaining finish an hour or two after after applying a coat. In fact, I usually sort of buff it vigorously with a coarse shop rag to the point of generating a little heat from friction. (I have actually applied the VO as a friction finish on the lathe and in my experience it appears that the heat from the friction does make it setup much more quickly.) And if there is any tackiness left when you are ready for the next coat, don’t apply the next coat until it is gone. If it doesn’t’ seem quite ready at that point, I usually buff it again and wait until it feels smooth to the touch before applying the next coat. BTW, I bought my can of T&T VO about 3 years ago and It does seem like it takes a little longer now than when it was fresh for each coat to feel smooth and ready for the next coat than it used to, though it could be that I am just more impatient these days or environmental conditions in my shop are different somehow.

Japan drier will speed up the process immensely. I mix it approximately 1 part drier to 64 parts oil. Since it’s best to only treat what you’ll be using, I generally take one or two ounces of oil and add one-half or one milliliter of drier using a pipette. Try it on a test board.

I’ve used T&T varnish oil for quite a few projects and it is really nice if you have the time to apply it and patience for it to dry afterwards. What I generally do is apply a good amount, rub it in the wood, and then wait 30min or so and then aggressively wipe off whatever is left. I let it dry for a few days, use a brown bad to smooth it, and then add another coat. 4 to 5 coats is what I usually do and get a nice film finish. But ya, like other posters said, it takes some time for it to dry but I think it is worth the wait.

Reading this may help. For a thin film “naked” finish I encourage you to try plain old mw poly thinned 1:1. Flood the surface, keep it wet not sopping, for 10 min, wipe off, dry, repeat. 2-4 coats depending on what you want. Can also do 3rd coat and above like a regular wipe on, ie leave more on the surface. It will dry faster that t&t and be a harder finish, and a lot cheaper.

Have your say...
