Q: Can I put one coat of oil based polyurethane on some drawers, wait eight hours or so, and then overcoat the oil based polyurethane with several topcoats of waterbased polyurethane?
A: Sometimes. That is to say, some waterbased polyurethanes will adhere to some oil based polyurethanes, but not all will do so. I’d let the oil based finish dry thoroughly (at least 24 hours), then add one coat of Zinsser SealCoat, which will ensure good bonding between the oil and water no matter which brands you are using.

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