Hi, I am about to get my hardwood floors refinished. The guy who is going to
refinish them is going to use a water based sealer and an oil based poly. No
stain.

Is this ok?

Also how many coats of poly should I get, 2 or 3?

I am in the San Francisco Bay Area.

Thanks

You're fine with water based sealer and oil based polyeurothane. As far as the
coats of polyeurothane goes use this rule. The more the better. It is better to
go with say four thin coats than one or two thick coats of polyeurothane. I
would go with four thin coats or three. If you put on a thick coat it tends to
be less durable.
