I've read you have to delay painting PT lumber from everywhere from two

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?


I don't know how long you need to wait.

As for paint... might I suggest an opaque stain. Depending on the
concentration and size of pigment, it will get deeper into the grain of
the wood than paint, but from a distance looks like paint. It lasts a
lot longer than paint and fades instead of flaking/peeling.

Last porch I built, I used PT lumber with a white opaque stain. Up close
you could still see the grain of the wood, which was an attractive
feature. From the road, it looked like a newly painted white porch. It
stayed bright white for several years.

Good idear, I'll look into it. I wouldn't use white stain tho, something
red-ish -- which fades quickly in ultraviolet.
Is there an exterior polyurethane that can protect pigments form UV? Or are
there UV-impervious pigments?
