We just had our hardwood floors refinished (and stained) with four
coats of oil modified urethane. Does anyone know how long it takes for
this kind of urethane to reach it's full strengh. I'm hoping to stay
off the floor until it's fully cured ... unless it takes months :)
Thanks,
Harry

The label on your urethane will tell you.
I think the minwax oil based poly I used was okay to walk on in a day
or so, but no furniture for a week I think?

It's not me doing the work, so I don't actually have the label from the
can ... so why don't I ask the contractor you say ... well, he does
great work, and at a good price, but there's a very big language
barrier which makes it hard to talk to him, not to mention the fact
that you can only reach him on the cell which cuts in and out making
things even harder.
Thanks,
Harry

After a day you can start placing things, just be careful and no sliding.

Oil/Varnish (urethane) finishes are Reactive Curing finishes -- they
bond with oxygen, or there is a catalyst in the mix -- so when the
thinner evaporates a reaction occurs... Cross-linking or polymerization...
I suspect it is oxygen curing -- cures from the top down -- so If the
coats are thick (brushed on), I would treat it gently for a month... But
that's an _opinion_ -- no facts to base it on till you give more info --
just a suggestion that has a wide safety margin.
You did not specify the brand or the exact type -- so at best people
could only guess -- since they have no info on the type.
You got some good advice to call the manufacturer, or look up their web
site -- since there is a fair bit of variation in curing times.
Get understanding Wood finishing by Bob Flexner if you want more detail
than you could ever wish for.
