I recently purchased and applied Golden's Tung Oil to a wide pine floor. I followed the manufacturers instructions to a tee but the oil isn't drying. It has been over a month. I tried several times to reach the maker but he never returns calls nor emails. I decided to scrub the floor again with just thinner to see if I could get the excess oil up but it still appears to be oily. The obvious problem with that is that it is tracking all shoes. What suggestions might you have?
