I'm certainly not an expert, but in my own floor travails, "the word" was
water-based polyurethane *with a catalyst*
for hardening, that is sposed to
be very hard. 4 oz catalyst per gal poly.
Altho I must say, the really gorgeous floors I've seen were always done in
oil-based--but harder to work with.
I believe the polyurethane might be able to "fill" the scratches, so they
are not so visible, sorta like wax on plastic--really on optical effect, but
sure beats sanding. Maybe a combination of sanding/filling w/ poly.
5-6 coats of finish is pretty good, more than most, but I've heard from some
floor guys that 10 coats--and more!-- is not unreasonable.
Maybe instead of coats, they should start talking fractions of an inch!
But for animals claws, etc, you might want to search under "clear epoxies"
and "floor", and see what that yields. Proly super super expensive, if it
