When I moved into my house I had the floors sanded and polyurethaned.
It's now 8 years later and the PU seems to have pretty much vanished.
I understand that they should have done 4 layers or so but they only
did 2. Then again, I didn't pay them very much since I didn't know any
Now the question is, can I just lop some more on top or does it have
to be removed first? How long before I can walk on it?
Clean it, lightly sand it, clean all the dust. Then apply each coat allowing
the drying time stated on the directions. Some are 2 hours, others are 6 or
more. I'd wait 24 hour before using it. Lightly waling on it with stocking
feet may be OK but it does take some time to reach full hardness.
you can redo no big deal read instructions probably need to clean light sand
then a few coats. best bet is to get a hotel/stay at friends for the night.
Probably 3 coats should be good make sure you will have good light and if
you have gas see if vapors flammable turn off pilots!
