Hardie is pretty porous. So it is best to paint all sides. If moisture
penetrates from the back side to the back side of the paint the paint

Well, the latter is obvious; the former surprises me to learn--I had
assumed given the base material/weight it would be dense-enough to be
essentially impervious; hence its advantage. Lacking that, I see little
at all to recommend it in lieu of alternatives.

In hurricane country or where there is driving rain during storms the
water can get back behind the panels and another reason that you wrap
with a water barrier before hanging the paneling.

But Hardie does not rot nor is it food for insects.
