Q: Can I put an oil based urethane on top of waterbased Varathane?
A: Yes. Varathane is polyurethane, and oil based urethane can go over waterbased, provided the waterbased is fully cured and all the water is out of it. Do bear in mind that one of the reasons for using waterbased polyurethane is that it goes on clear and does not yellow over time. Oil based goes on slightly amber and does yellow over time, so expect some color change if you switch to oil based in mid stream.

Gentle reminder: A modest donation to this finishing blog can keep it going to help others. Thanks!
