Re: Rockler's Tung Oil
That is really tung oil.
http://www.rockler.com/tech/RTD20000304AA.pdf . Most of the "tung oil
finishes" are some other oil / varnish / thinner blend to give a tung
oil "effect". Not that most people know what a tung oil finish looks
Be warned that raw oil finishes are slow drying. Tung oil may be
faster than the others, but depending on temperature and humidity you
are talking a week or two to appear to be dry and two weeks to a month
to be really dry. By dry I mean fully cured by reacting with oxygen to
By the way, you do know that if you wad your rags up and throw them in
the garbage, the reaction of the oil with oxygen can start a fire? I
wash my rags out with solvent and then spread them out somewhere to
I hope you spread them out somewhere where they won't
burn your house down if that method fails.
If you're rinsing them for re-use either you use a lot of oil
finish or you are awfully cheap!
Somewhere back in the Google archives of this newsgroup
there is an article by a fellow who used to hang his rags on
the clothesline to dry. One day one caught fire.
He probably didn't rinse them first, but still...
The common instructions for disposal call for sealing the
rag in a metal container, like an old paint can that is partially
filled with water. You can keep doing that until the can is
full of rags then toss it in the trash.
Once the rags are hard and stiff the danger of spontaneous combustion
An alternative is to deliberately burn them, if you have a safe place
to do that.
Raw linseed oil is used by artists, who want as much
working time as possible, several days, usually. If you
really want a fast drying linseed oil, Tru-Oil gunstock
oil is impossible to beat. Two hours between coats.
Full cure takes less than a week. Builds almost
as fast as varnish.
That's good also. Kind of oversold on the durability even after fully
cured but a good finish none the less. I try really hard to get my
film finishes thin and dulled to look much like an oiled finish but
with a little better durability only needing wax for the rest of their
life. True oil finishes should be renewed every year or two.
