Hardi may all come primed now but it did not always. It used to come in

And, I can assure you 90% of Hardi does not get primed on all six sides.
Construction crews don't paint the ends after cutting to length. I
suspect that caulk will substitute.

You're probably right, but it's taught in the BEST Continuing Ed class
that I just finished yesterday. That very many people do so is fairly
unlikely, but the better builders will, and I will in the future.
Swingy, what's your company's stance on this?

I already prime cuts in PT because I know the wood will quickly
corrupt otherwise. I tried for over a year to find a
termiticide/stain on the market but they discontinued it and our
gov't, in its wisdom, made it -illegal- to make your own replacement
or modify any existing product! I now use a brown deck stain (with
mildewcide but no bug killer) on brown PT and you can still buy
green-died preservative (I have some Jassco Termin-8 for the green
PT.)

Not priming every cut reduces the lifetime of the siding. That's why
JH strongly suggests that we do prime it everywhere, back and cuts. If
your paint peels and you didn't prime, you're SOL.
