When is it too humid to paint?

[Sleeping in EQ]

I need to paint my son's treehouse. I'm using primer and an oil-based paint. How humid is too humid?

Unless you are in extreme humidity, you should be ok. We painted with oil in Texas around this time of year and didn't have much problem.

It may take a couple of days to dry, however.

Where do you live? I would say that you would be fine unless there was a ridiculous ammount of humidity. As noted above, it may take a bit before it isn't tacky. I say paint and when you are done with that you can help with my deck!
