Optimal temperature for interior painting?

I need to paint an interior stairway. It's probably in the upper 40s to mid-50s in there now.
Am I asking for trouble?
Thx.

What's it say on the can ?

The manufacturer has the best tech info and it will be in the instructions.

FWIW - I have a buddy that runs a commercial painting company and they paint outside
down to about 40° with the proper paint.

My can of interior latex says apply when the air and surface temperature is between 50 and 90. It might take it longer to dry than if it was warmer, but, as long as you're not expecting any freezing temperature, I think it'll be OK.

Don't go below the minimum temperature given on a can of latex paint. Latex paint without special additives applied in too cold conditions will not cure properly and will often peel. Better to be at least 5-10 degrees over the minimum. Oil paint has a bit more latitude towards application in cold conditions

"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

80 degrees. For you outside in the sun lounging while someone else does it for you.

Didn't think of looking at the label. Haven't really seen it since summer. Will have to remember to do so next time I'm over there.

Update-- label makes absolutely no reference to temperature.

Googling,typical minimum temperature for latex paint is 50 degrees F, unless additives were included to lower the application temperature allowed. So if the can does not list a number, I would go with 50. But the surfaces should also be at least at that temperature, and stay at or above the minimum for at least 36 hours. The 5-10 degrees extra I recommended earlier gives some leeway and speeds up the curing of the paint film.
