I want to attach Hardie plank fiber-cement lap siding to my concrete garage walls. It's a very small surface which requires something like 3 boards altogether. I am only covering it for decorative purposes to hide old ugly concrete and stucco.
The garage door is trimmed with 2x6 boards and so I am attaching 3/4" (actual thickness) furring strips to hang siding. Hardie plank is 5/16" thick, so I will have 1-1/16". Is there any usable nails that I can use in finish nailer for that? I can't find anything shorter than 1-1/4". Will regular finish nails work?
Am I stuck with hand nailing those boards?
Also, they recommend 1-1/4" nails. So how bad is it if I use 1" nails?
