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

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

Also, just curious: Will non-PT wood last as long as PT wood (outside, of
course), if it thoroughly painted?
In the northeast. Any special painting methods required?
