Pre-drill your Hardi siding and attach with screws.
Depending on the ICF system you have, you may need to "bridge" between tabs. Inevitably, a horizontal seem will occur where you do not have a tab, so you will need to provide something to screw to. We use metal flashing, attached to the tab above and below the horizontal line of the siding. In an 8' wall, I believe we needed to do this at 2 different levels. This will depend on your siding dimensions. Capisca? |

We install direct with a r/s nailgun into the poly straps. This was after a discussion with Hardi back when I was doing my own home. Every thing has stayed tight without any problems.
Note that previous threads have indicated that cold weather may complicate installation with a nailgun by allowing cracked strapping.

our builders use the method described above, ie bridging the polysteel furring strip gap with galvanized metal strips. they then use anyone of several screw types, when blind screwing is allowed (overlap covers the screw). if double fastening is required, as in coastal hurricane zones, screws are pre-drilled and countersunk. some of my builders are using a nailgun with galvanised ringshank nails successfully, as above. last method would be to p/t fur(r?) the outside and use nails, as with a frame house.

We are the dist. for ECO-Block. We have used pnuematic nailguns on every siding application, including Hardi and Cemplank. I cannot vouch for many other systems, but I know that it has worked on ECO. The important issues are the fastener and the air pressure setting, i.e. psi, on the compressor. Our carpenters have preferred a 6d ringed shank nail, the larger the head diameter, the better.
The pressure has to be tested on each project. Not only do atmospheric and temperature changes effect these tools, different compressors have different gauges, etc.
Check with your dist. and see if their nailing flange will accept nails shot from a nailgun. Good luck.
