Polyurathane on wood floors Answered

Going to be refinishing some wood floors.  Sanding off all the old finish, then applying an oil based stain, and finaly polyurathane.  My question is can you use a water based polyurathane over an oil based stain?  If so, how long do I have to let the stain dry before applying the polyurathane?


Acrylic finish is water based, Polyurethane finish is oil based and, both are recommended for floors . The difference between the two is that the oil based Polyurethane finish will last longer between coatings. Polyurethane 5 to 6 years and Acrylic 3 to 5 years.

Sorry, that's not correct. There are water-based polyurethane finishes, as well as oil based polyurethane finishes.

As a painter I'd say: Better stay within one system, it's safer.
So: choose oil based or water based, and stick with that for all coats on that surface.

So since polyurethane is excellent stuff, I would look for a water based stain instead, and keep the polyurethane as a part of the plan.

Water based paints are more pleasant to use inside a home anyway, they will stink up your house a whole lot less and dry quickly.

My suspicion is the same as yours probably was, that a water-based varnish will not "take" on an oil-stained wood, by we'll have to wait for a more knowledgeable response, I think.
