Furniture, Wood and Cabinetry Finishing - tacky knot-holes

I posted a question yesterday about tacky knot-holes, but inadvertently forgot to check off the reply window. I guess I'm more at home in the garage than on a computer.

I am still puzzled as to what to do about this problem.

I fine-sand the top and will let the table sit for a couple of days in the hopes that this will allow the knot-hole to dry out.

Does anyone have any suggestions?

The "guy" at the paint store suggested I varnish the offending knot-holes and then urethane the entire top again. I feel uncomfortable about this.

Please help with this sticky (pardon the pun) problem.

The "old timers" (and I include myself in this category!) solution to knot holes was shellac; before proceeding, though, I'd check the directions on the polyurethane I plan to use.

When shellac was in it's prime as a sealer, poly hadn't been invented; standard varnish was the durable finish of choice, and was (and still is) completely compatible with shellac.

Some polyurethanes are - some aren't - check the can.

Thank you very much George for your advice. I will do some research into the varnish and the urethane just as you suggested and give it a try.

Right now it's very humid in Toronto so I'm going to wait a bit before I do anything.

I will let you know how it worked out.

Again, thanks very much.
