Hornmiester Posted July 7, 2014 Share Posted July 7, 2014 I have a raw birch cab that has several coats of Formby's tung oil. Can I use Minwax stain over the tung oil? Quote Link to comment Share on other sites More sharing options...
JJkizak Posted July 7, 2014 Share Posted July 7, 2014 That would scare me a bunch. Other than sanding it off I have no suggestions other than to try it on another piece of wood.. JJK Quote Link to comment Share on other sites More sharing options...
WMcD Posted July 8, 2014 Share Posted July 8, 2014 My guess is that just putting on a stain is not going to work. If I had to experiment I would apply the stain using 320 Wet or Dry paper. This is going to scrub the tung oil. I'd expect a slurry to be formed and you'll have to wipe it off with a tee-shirt or paper towel. Overall it is not possible to predict. If there is some inconspicuous spot, start there. WMcD Quote Link to comment Share on other sites More sharing options...
Marvel Posted July 8, 2014 Share Posted July 8, 2014 (edited) Tung oil works similar to boiled linseed oil and polyurethane. Tung and blo, do organically what poly does. They are self catalyzing... hardening as they dry and sealing the wood. I think Gil's idea is a good one.

MAZ Posted July 8, 2014 Share Posted July 8, 2014 Tung oil is great and I use it on everything. It gives such a rich, natural and HARD finish. That said, stain will not penetrate the tung oil. The oil is the sealant. The stain will just sit on the tung oil and eventually will rub off with everything that touches it. Removing tung oil is a mechanical process (sanding/steel wool with mineral spirits), there is no 'stripper' for oil finishes (that works). If you were looking to go darker with your existing finish; I believe there are tinted Tung oils. Additional coats will darken your piece. Good luck.

Sancho Panza Posted July 8, 2014 Share Posted July 8, 2014 MAZ, I agree with you, for the most part, but, have found Easy Off oven cleaner will remove Tung Oil & Boiled Linseed Oil; at least on rifle stocks. Prolly would work on speakers; but, you have to use this OUTSIDE, with GLOVES AND figure a way to rinse COMPLETELY with WATER AND NOT damage the cabs or components. Have never tried this, so YMMV. Anyone else think this may work? If anyone tries this, be very careful!!! Maybe a small test area on the bottom 1st? Quote Link to comment Share on other sites More sharing options...
Hornmiester Posted July 8, 2014 Author Share Posted July 8, 2014 Thanks all, I think I will go with the dark tung oil option. Sound safest. Quote Link to comment Share on other sites More sharing options...
MAZ Posted July 8, 2014 Share Posted July 8, 2014 Thanks all, I think I will go with the dark tung oil option. Sound safest. I would. Just keep applying it until it gets darker. Wait a day in between coats. Quote Link to comment Share on other sites More sharing options...

MAZ Posted July 8, 2014 Share Posted July 8, 2014 (edited) I think that OLDTIMER maybe referring to the issues of water and veneer. Things can start peeling if the veneer glue is compromised by too much moisture or hard chemicals. Solid woods are more forgiving than paper thin glued on veneers Edited July 8, 2014 by MAZ Quote Link to comment Share on other sites More sharing options...
