I recently made a solid cherry desk for myself. I haven’t had a lot of chances to test out pure oil finishes, but since this project was just for the house, I figured if things went wrong, it wouldn’t really matter. I made the desk and smoothed with my #4 and touched up with 320. I decided to try a pure tung oil finish. I mixed the first coat of pure tung oil 50/50 with mineral spirits and generously wiped on, waited 15 minutes, and wiped off. Let dry for a day, then I did a second coat of about 75 oil /25 mineral spirits. Same process of wiping on and wiping off. All looked well at that point. I went out of town for a bit and came back 5 days later with some unpleasant results. Nothing was ruined by any means, but the grain was totally raised and I might as well not have sanded in the first place. If you are wondering, I did not raise the grain with water during the sanding process. Never have before and I have never had issues. The wood also took on a relatively ugly blotchiness. I have used oil based poly on cherry before and I think the blotching there looks just fine and actually adds to the character. For me, poly has always helped ribbon or curl really pop. This tung oil just sort of turned the irregular grain into fugly blotches.
Anyone else had the same results?
Should I just ditch pure oil finishes if I can get better results from poly?
