?? About nail gun for hardie trim siding

[Randy C]

Does anyone know if it takes any special pneumatic nailer to nail HArdie trim boards. Specifically I will be nailing the 3/4 in thick hardie trim and this stuff is very hard.

would you use 15 or 16 gauge nailer. I can buy either nailer on Amazon but didn't know if these would have the power to nail thru this material.

Thanks

I know Hardie recommends Hot Dipped Galvanized (not Galv Plated) or Stainless nails. Not sure you can get Hot Dipped for a nail gun so it would have to be stainless nails.

They have specific installation instructions.

Thanks, but I know all this. I am trying to find out if a regular 15 or 16 gauge nail gun will have the power to nail thru this hard material or does it take some specialized gun or an air compressor that goes above 120 psi.

Doubtful on the 16-15ga finish nailer. Son uses a Dewalt siding coil nailer.

Think a "siding nailer" is what you want, which I think is in between a framing nailer and finish nailers.  Pros would know more.

I just installed Hardie Panel siding on my shed two weeks ago.  I used just what it said on the data sheet.  6d galvanized.  I hand nailed and thought it would be a hassle, but it wasn't bad at all.  A good whack with the hammer and the nail went right through and hammer them flush with the surface.  Pay close attention to the recommended offset from the edges for nail placement as there was one spot where I got a little close and it cracked a little on a corner.

You can hand nail the trim with stainless steel siding nails. No problem nailing thru the Hardie Board. If the nails won't show then a roofing nailer will work too.

They have a Facebook page and are fairly responsive to posts - could just ask them.

Ok, I figured if you knew all of that you'd go this route as suggested.
