Polyurethane Floor Coating Questions, Please
 

Hi,

Will be purchasing a new house in which the wooden floors aren't in the
greatest of shape. As it's been a very long time since
I thought about this, would like to ask:

a. Is Polyurethane still the coating of choice ?

- If so, for a living and dining room floor, what do most folks use:
semi-gloss, or... ?

b. Is there any consensous on a "best brand" ?

c. After an initial thorough sanding, how many coats are usually applied
for a living or dining room ?

d. Is it necessary to (lightly) re-sand between ?

e. How long, typically, is the drying time for, between coats ?

Much thanks,
Bob
