Hi,

I am looking to refinish a Numebar desk with varish (polyurethane). I am concerned that the varnish won't take to the factory IKEA oil finish. Has anyone have any experience with this or else any suggestions on a way to get a glossy harder finish.

Thanks,
Kas

I've put polyurethane over the factory oil finish on another piece of furniture, a solid beech finger-jointed shelf that's now discontinued. It went on with no problems and has held up well. I wouldn't hesitate to use poly on the countertop.

You should be aware that it's not considered food-safe, but if you're using it for a desk, that should be no problem.
