I've read you have to delay painting PT lumber from everywhere from two
weeks to a year. Latex paint...
What's the deal?


Contains a lot of moisture and the paint will peel. I'd wait a year
or so.


And, how does one tell if PT wood is ready to be painted?
It feels quite wet from the lumberyard/HD, but seems much drier in a cupla
days.
Does rain further extend the wait?

Not really, the rain does not get absorbed because the PT is saturated
with other chemicals.


Does a sprayer allow you paint sooner than brushing/rolling??

Nope, peeling is peeling.


Also, just curious: Will non-PT wood last as long as PT wood (outside, of
course), if it thoroughly painted?

Look at the oldest house in your town. Chances are it is from the
1700's and if painted and cared for, still in good condition.


In the northeast. Any special painting methods required?

Wait for the snow to melt. Read the can, most paints should be 50
degrees or more, a few can tolerate 40 degrees.
