Does urethane dry faster in the sun?
It dries as the solvent (which may or may not be water) evaporates. It isn’t like masonry where time and moisture are critical. There’s no problem applying urethane in the sun other than the challenges it poses to the actual application. Very quick dry times mean less time to get good coverage and work out runs.
How long should urethane dry between coats?
24 to 48 hours

Will a fan speed up polyurethane drying time?
Will a fan help dry polyurethane? Use a fan to direct fresh air over the area. It can take up to seven days for the urethane to be 90 percent cured and 30 days to be cured completely. However, you should need the fan only for the first day, with periodic use after to remove buildup of fumes.
Why is my polyurethane not drying?
If you experience oil-based polyurethane not drying well, it’s not likely that it’s bad polyurethane. It’s more likely that the wood you’re finishing contains a natural oil or you have applied an oil to the wood and the oil hasn’t dried. It will speed the drying, just not very much. …

Heat may speed up the curing process, but that would be a dangerous game to play. Polyurethane finishes are HIGHLY susceptible to UV damage. Putting it in the sun would be a BAD idea.
Why do you have to wait 72 hours between coats of polyurethane?
The reason for this is, the solvents in the second coat must be able to disrupt the final cure (of the first coat) enough to penetrate a soft film, and still provide enough “open” time to allow for the dry-through solvents to evaporate (the low-flash solvents are gonna evaporate very quickly).
How can I make polyurethane dry faster?

What can I do to increase polyurethane dry time?
Last night I rag applied a 50/50 polyurethane / mineral spirits blend. Now, 10 hours later, it’s still too tacky to sand. I turned the AC up, thinking that will drop the humidity in the room. Anything else I can do add to the mix to increase speed time?
What happens when you apply urethane to polyurethane?
Applying urethane is as simple as using a paintbrush. The hard part comes when waiting for it to dry and cure. Polyurethane dries in two steps. Evaporation dries the surface to a tacky consistency, and curing hardens and strengthens the formula.
