Tung Oil on plywood floor sticky
A plywood floor was installed in the heated “crawlspace” under our cabin which was to be used as a workshop. My husband finished it with Danish Tung Oil. On 50% of it, he did a second coat which is now sticky. I suspect it was applied too thickly and not wiped off sufficiently. It has been about 5 months now and it is still tacky in spot. Running shoes stick and squeak. I tried coating it with Mineral Spirits, then wiping it off. This helped a wee bit, but not enough. Any ideas how to fix this? Can I use an oil based flooring paint or poly over it? Sand it off and start again (I really don’t want to do that!) Suggestions?
Seems like the coats were applied like polyurethane - which is way too thick. Tung oil dries from the outside-in. This means that the inside has to dry through the "dried" top of the finish.
Using a buffer (rent by the day) with a green Scotchbrite pad, buff the floor to remove all the soft finish and then leave it alone for a week with a fan circulating the air 24/7. When dry, vacuum floor completely. Apply a coat of Tung oil throughout - a 4' wide strip at a time. Apply oil, wait 10 mins and buff off using a buffer + White Scotchbrite pad + towel (available at a flooring supply or big box. Repeat on the next 4'. After buffing last strip, allow floor to dry. Tung oil floors should have 3 coats.
Hope this helps.
Thank you Frankie. I will give this method a try.
