How long to wait between sealer coats

I applied polyurethane to my red oak baseboards two days ago. I am
going this work in our garage and it has been raining for two straight
days. I was going to sand the baseboards to prepare them for the
second coat but they still feel tacky. Is this how they are supposed
to feel after the first coat of polyurethane?
Thanks.
Sandy

Wait until the surface is no longer sticky/tachy. The surface should feel
smooth and non tacky.
Typically the instructions indicate the humidity and temp range to use the
product in. Sounds like the rain is the problem. Under ideal conditions
you can sometimes recoat in as little as 4 hours. In cold or humid
conditions the wait period can be several days or until the weather dries
out and or warms up.

How old is the poly? Most finishes have a 1 year shelf
life at best.

If it's fresh, did you cut the poly? First primer coat
works better if thinned 50%.

Huh? I don't think so.

Leon is spot-on. low temps and high humidity slow down the curing process.
60 degrees and humid can triple the time stated on the can.

The process of curing should obey Arrhenius's equation, so as a rule of
thumb, every drop in 10 degrees C halves the reaction rate (curing process).

More important, what is the temperature? The lower it is, the longer it
takes.

Is the coating still tacky or is there enough condensation on it to just
make it feel that way? If it's tacky then somthing is
wrong--polyurethane (at least single-part oilborne polyurethane) requires
moisture to cure so high humidity shouldn't cause it problems.
