I stripped a 30 year old oak table and then sanded the table with 60 grit sand paper to be followed by 120 and then 220 grit before staining.about 3-4 days after stripping,I noticed a sticky liquid area on the leaf. It covered an area aprrox.10″ by 6″.I sanded again and it almost disappeared. The next day it reappeared,although not as sticky. Any info would be appreciated.
With Oak this is a puzzlement to me. Pine or other heavy sap woods I would suggest it was just that, sap.
My thought is that you did not manage to remove all the stripper from the wood prior to beginning your finishing process.
If that be the case, you will need to start from the beginning on the leaf as the stripper will never allow the stain nor the finish to dry. Most strippers use beeswax as the agent to reduce evaporation during use. If all the beeswax is not removed it will cause the stain and the varnish to not dry and remain sticky.
