I understand that the Hardie Fiber/Cement clapboard type of house siding
pre-painted if one desires.
Question: how is the problem of the nail heads then handled ?
Do you have to hire someone to just go around and put a dab of paint on each
nail head ?
What am i missing here, please ?
the siding is blind nailed, that is the siding is nailed about an inch
from the upper edge and piece above covers it. in those spots where
this is not possible (like up against the eave), then yes, you have
someone dab a spot of paint on the nail. color matched touch up paint
and color matched caulk should be available.
Be aware, priming and painting is a all side proposition. Hardie siding
panels are ONLY primed/painted on the Top Side. All cuts and the back
side need to be primed for long life and any exposed nail heads and
seams need paint/caulk.
Why in the world would you back-prime cement siding? I can see it with
wood, where you nail the siding up against the sheathing, but cement
board needs an air gap to keep condensation from rotting out the
framing. With proper ventilation, painted one side should be fine.

Hardie Panel or Hardie Plank both are heavy paper coated with cement.
When they are in long term contact with moisture, they will fall
apart. Nailed to the frame, there is NO air circulation, so if
moisture gets behind the siding, it will fail.
Failure to prime the backside was a common, almost universal building
practice here in the early 1980s. Almost all of these homes have had to
have their siding replaced as a result of the builders NOT following
mfg's directions with wood siding.
You are missing the point. Cement based siding has been on the market
long enough for the first wave of house repairs to start coming in. It
has become obvious that you do NOT attach cement board siding directly
to the sheathing. Cement board siding WILL draw moisture, particularly
on the north side of the house, causing rot in the sheathing and
framing. The way to avoid that is to install thin furring strips to
space the siding off of the framing enough to provide air circulation
between the siding and sheathing. Lath will work, but most installers
now use 1/2" treated furring strips.
With proper ventilation behind the siding, back priming is not
WRONG .. .. .. I've seen samples of Hardie product sealed in a block of
Lucite filled with water .. .. there was absolutely no evidence that the
material was in any way affected. This is/was, in fact one of their
main selling points.
