Can you apply a drying oil over a polyurethane that is not drying tacky I have stained a crib and have sprayed polyurethane over to seal but the poly is still tacky a week later?

Drying conditions of certain paints and sealers can be critical. Read the directions on the can. Sometimes the manufacturer will specify a certain temperature range and/or humidity level for the paint or sealer to properly dry and harden. You may have exceeded the time range for the polyurethane and it may be best for you to remove the sealer and start over. Make sure it's warm enough and that your humidity level is low enough then the sealer should dry properly. Good luck.
