exterior painting, when cold
when is it too cold to paint outside ?

When the surface temperature of what you are painting is 35 degrees or lower. Personally, to play it safe I rarely paint outside in temps lower than 50. Why? Because night time temps can dip below freezing and cause all sorts of problems for new paint film. You really want your paint to CURE and for that to happen you really don't want temps dipping below 35 for at least a couple weeks. This time of year is tricky because it can be 70 during the day and then get foggy/dew at night as temps drop drastically overnight. I always plan on somehow making sure the sun hits the side I am working on for at least a couple hours to give the paint a good chance of drying before evening.

I did not do a lot of exterior work but when I needed two pairs of mittens and the paint in the can was frozen solid, I guessed it was getting too cold to work out well.

Seriously and as mentioned, when temps cannot be counted on to be above 50 and especially if you live in a climate with a dew or fog issues that settles below 40 it would be best to wait until spring.

That said, there are exterior paints and stains, and additives that say they extend outdoor work to 40 or below. I guess I am too skeptical to buy into the concept.

A good rule to follow is an ancient painter's rule.........if it HAS to be done then by all means paint it even tho it's cold out, if it can wait til spring, well, wait til spring!
