Tom,
I'm somewhat confused because the polyurethane I have says to apply
additional coats within two hours, before it dries. It says to wait 48
hours, if you wait longer than 2 hours between coats. What kind of
polyurethane are you using? It isn't the water based type, is it? I
remember resurfacing a table top once and I know that I applied many coats
of polyurethane spray without waiting more than 10 minutes between coats
and I had no trouble at all. Regards.
Paul
