Ring Shank Nails With Fiber Cement Siding?

Jer

I recently read that ring shank nails should not be used with fiber cement siding because they can blow out a hole on the inner side of the panel thereby causing nail hold failure.
Has any one else heard this?
Any feedback will be appreciated

Seems to me that any nail would cause the same blow out.

I'm not sure how ringshanks would cause that.

if you overhang a pc of hardi on a bench and shoot a ring shank thru it you will most likely see blowout on the backside.
But with the panel supported as you normally do siding i dont think it does blow out.imo

when you blind nail its not supported.

how do you mean Al?
its supported by the wall

A W Smith

If you install by blind nailing just above the exposure. There is a space between the hardi and the wall. Not much. but there is a slight space. only the top most edge of the hardi touches the wall and the bottom lays against the previous course.

yes ,a small space caused by the overlap? i see your point

Are you using a hitachi coil nailer or maze nails? I've even seen a hardi training tape back in the day using 2" roofing nails.
Personally, Ive used them all and almost prefer the hand nails...no air to run and I love the sound of my stiletto in the morning. the crew on the other hand NEEDS the air guns, or they wont make wages!

I would love to see an instructional video.

I attended a lumber yard vendor's breakfast put on by Hardie about a month ago. The rep for the west coast region said that they recommend smooth shank only for their siding products.

It wasn't from back side blow out as much as the ring shanks make the hole bigger and looser than a smooth shank. (I don't know one way or the other...its just what the dude said).

ive used a ring shank and i gotta say if i had to remove a piece it was tuff to do.

I have a Makita siding nailer i got almost new for a bargain at an automotive swap meet (go figure) I use it mostly for pine soffit or lite sheathing work, Where can i get smooth wire collated plated siding nails? All Ive seen available were ring shank.

never mind,

I have been using the Hitachi coil nailer for all my fibercement and ring shank nails since my hardi rep recommended them way back when fibercement first became popular here in Utah fifteen or so years ago.
In light of what Wallmaxx is saying I wonder if there has been recent studies or problems that have caused hardis reps to discourage ring shank use now.

I hope not!
does that go for screw shank too?
I just finnished my first fiber cement siding job. It was the 4x9x3/8 sheets and hand nailed it with 6 penny screw shank siding nails.

Jer

Screw shank nails were not mentioned in what I was reading...very good question though. You probably have nothing to worry about. Were you nailing batts over the 4x9's?

dlcj

nope, not this time. Its up to the painter to get a good coat of paint on there and caulk what needs to be. It'll probably be painted a dark color and the nails wont show to bad anyway.
