Put a cork in it?

Hello all, I am doing coasters for Christmas this year. Actually, these are last years Christmas gifts that were put on the back burner so I could finish one of the pedestals that go to our dining room table. Talk about a bad time to start a new project. The only people who received coasters were my folks. So, here I am, back at it. This brings me to the question, should I apply my polyurethane to the coaster before putting on the cork, OR should I put the cork on before I apply the poly? When I made the first set I applied poly everywhere except the cork recess. Is that the way I should go again? I would appreciate your thoughts concerning the matter.

The purpose of the cork is to make a non-slip surface for the glass, etc. and to soak up some of the condensate and/or dribbles from the glass. If you were to put poly on the cork, it would not do it’s job. I would think that you probalbly want to poly the recess for the cork to seal the wood (if the bottom side is also poly’d). I other words treat both the cork recess and the bottom the same to reduce the likelyhood of warping.

Ditto – I poly the wood before attaching the cork. Condensation will probably soak through the cork if your air is at all humid and you want to prevent it getting into the wood.

Ditto ditto.
The purpose of the cork is two fold. Non slick and absorption.
The cork will get damp. Best to poly under it also.
