Hello,
My home's Exterior is due for re-paint. It's hardy-plank siding. Is it OK to paint now given overall low temperatures and the fluctuations?
My painter says Sherwin williams duration paint can be used till 35 deg F. I figure rather wait till mid March?
Thanks.
SW specs temperature above 35F for 48 hours after application (for certain paints including Duration) which is improved over the 50F of a few years ago. Also be aware of the dew point as you don't want the fresh paint to be subject to moisture condensing on it.
Here's a snip of Duration info which gives SW lots of wiggle room:
When the air temperature is at 35°F, sub-
strates may be colder; prior to painting, check
to be sure the air, surface, and material tem-
perature are above 35°F and at least 5°F
above the dew point. Avoid using if rain or
snow is expected within 2-3 hours. Do not
apply at air or surface temperatures below 35°
F or when air or surface temperatures may
drop below 35°F within 48 hours.
On large expanses of metal siding, the air,
surface, and material temperatures must be
50°F or higher.
I am no expert, but I wouldn't do it. I had my trim & porch painted in similar conditions, actually I think temp was in the 40's, with the same paint and it didn't hold up 3-4 years later it had splits and cracks and chips on window ledges, I had to touch it up myself. I believe it's a good paint, but I'm not convinced it's good for use in cold temps.
Just because you can doesn't mean you should! Painting this time of year is risky with the temperature swings and overall lower temps. Paint won't cure as well below 55 degrees. It'll cure/set eventually but it won't hold up as well long term.
Thanks. I told my painter to try to schedule me for late March/April. (I had contacted mine back in Aug, and scheduling has been a challenge. The fact that he wants to paint now makes me unhappy.)
Does anyone have recommendations for an exterior painter?

I would be careful not to get into pollen season with exterior paint. I wouldn't want all that yellow pine pollen sticking to the wet paint, plus you would have to clean off your siding every day before painting to be sure it is clean.
Paint your house in March and it should be warm enough without any pollen.
