hi everyone,
a buddy of mine is having problems getting a finish to cure on some zircote.
he said he started with a tung oil finish that after a few days still didn’t harden.
then he tried a wipe on poly.
i told him it was probably the oils in the wood keeping the finishes from curing.
i suggested to try something like lacquer or shellac.
does this sound right to you guys?
any advice?
thanks,

Can also try wiping it down with mineral spirits before the first coat - that cleans the oils off the surface and allos the first coat to adhere and then later coats bond to the previous one

Just a question... If what you suggest works.. Then why do the other layers need it..??
Seems to me like snow on a mountain,, Disaster waiting to happen.. AVALANCHE!
I would think the TOP coat VERY dependent on the base coats over time... Just me..
I left out a W in allows. Once the first coat has been put on after wiping the wood with the mineral spirits, you let that dry then no more mineral spirit wipes, just continue finishing as normal by adding additional coats of your finish. The 2nd coat bonds to the first, 3rd to the 2nd and so on - no more mineral spirit wipes are needed after the first. That is just to clean off the woods natural oil from the top layer of the wood and to allow the first coat of finish to bond to the wood.1 - measure the board twice, 2 - cut it once, 3 - measure the space where it is supposed to go 4 - get a new board and go back to step 1
thanks again everyone.
i'll pass along all of your useful info to my friend.
it was one of those things where he was working in north St. Louis and stopped by Hibdon Hardwoods. he bought some stuff out of their "scraps bin".
i hadn't worked with zircote either, just kinda figured it was the natural oils in the wood keeping the oil finishes from curing.

Rick.. I was just funnin ya a bit!
Thats ok Will, my explanations can confuse me at times when I go back and read them. LOL just wanted to make sure this was not one of those cases.

It is not good practise to coat oily woods with an oil or oil based finish. Lacquer and shellac are the best finishes.
If you want to use an oil based finish, first put on a coat of shellac. If you plan on using a polyurethane varnish, be sure to use a dewaxed shellac.
Chills,
I was in Belize City last December and bought a few craft pieces. The local woodworkers told me they used furniture wax to finish their projects. No oils or poly. Most of their work is crafts for tourist , however, they do make some furniture. the pieces I saw turned out very nice.
Good Luck,
BigDaddy.
Is it possible that Linseed oil was involved (not boiled linseed oil). Linseed oil takes forever to cure (if it cures at all).
Put the piece out in the sun or keep it warm - that will speed up the curing of linseed oil.

Measure it with a micrometer, mark it with chalk, cut it with an ax.
