Topic tags/keywords: question walnut finishing

I need some advice. I made a 50/50 mix of pure tung oil (100% pure no filler) and mineral spirits. I put 2 coats on my walnut project allowing 2 days in between. Then 2 more days then minwax finishing paste wax. Light rubbing with 0000 steel wool in between each step. 7 days later the blotchy-ness is happening.

Did I not leave enough time for the tung oil to dry? Do I need to strip of the wax with mineral sprits and just stick to the oil mix? Hit with more wax and buff? Remove wax, re-oil, leave for long time and then rewax?

Help greatly needed.

I am no expert, but I have had the exact thing happen before. I believe the oil was not fully cured/dry. Putting the wax on it too soon leads to this. It appears to be the moisture trapped under the wax.

You could wait and see what happens but I think
perhaps you have the oil building a film in some
areas and soaking in in others. You can strip off
the wax and apply more oil to get a more uniform
appearance I think.

My first guess is you didn’t let the oil dry long enough. I usually wait a week or longer before I do anything else with it. I don’t use wax on any project so that part is above my pay grade. I personally would take as much wax off as possible then reapply the wax.
Other problem may have been that the wax didn’t dry long enough and you tried to rub it out too early. I also believe you apply the wax with Scothbrite/Steel wool and rub out with a cloth.
As well you didn’t say you wiped off all excess oil between coats.

With little to lose, short of removing the finish, you might try rubbing it out with a ScotchBrite pad or, say, a 0, steel wool first.

Update: I had not waited long enough for anything to dry. I stripped of the wax with mineral sprits and waited 2 weeks. Steel wool, one coat of pure tung oil, another 2 weeks. More steel wool, one last coat of tung oil, another 2 weeks. More steel wool then minwax finishing paste wax again.

Now its pretty.
