Hardie Siding Products Nailing Issues

In all my years in home improvement, I have witnessed what works as well as what does not perform well.  I cannot begin to tell you how many HardiePlank (James Hardie) Siding jobs I have come across with face nails and just after a few years are showing cracks in the surface due to the improper nailing procedure that was used. James Hardie is the manufacture and here is the instructions for Hardie Siding Installation for reference.

In our extreme Southeast Texas summer heat and humidity, there will be some expansion and contraction in the James Hardie siding product.

If the HardiePlank Siding is face nailed at the vertical edges (the ends of the plank), this is what could happen (Figure 9 at the right). When HardiePlank is face nailed, it should always be nailed in the main run areas away from vertical edges so cracking does not occur. 

Two Methods of Nailing (fastening)

Face Nailing Method

If face nailing should be needed, it should be kept at a minimal distance and away from each end of the plank if possible.  If face nailing should ever be required, for instance, let’s say if a plank is not lying flat, it should be nailed at least ¾” away from either edge (see Figure 10).

Blind Nailing Method

90% of the blind nailing should occur at the top of the lower panel of the siding that is being installed (see Figure 11).

By nailing this way, the nails will also be covered and hidden by the next panel that is installed above it which is more visually appealing.

This will ensure that there is no chance of breakage due to expansion and contraction after the HardiePlank crews are long gone.

Voiding The Warranty 

There is also the issue that James Hardie the manufacture of the siding product will void the warranty should the siding be nailed improperly. That is why it is so important to install the product to what the manufacturer specifies and recommends.

It is not uncommon for siding products to be installed incorrectly to varying degrees. Nailing is one of the most important aspects.   

 

Suggested Galvanized Fasteners  (nails) For Coastal Applications

Fasteners must be corrosion resistant, galvanized fiber cement HardiPlank nails, or stainless steel. Electro-galvanized are acceptable but may exhibit premature corrosion.
Hardie recommends the use of quality, hot dipped galvanized nails.

Stainless Steel fasteners (nails)

Stainless steel fasteners are recommended when installing James Hardie products near the ocean, large bodies of water, or in very humid climates. The beauty of properly installing HardiePlank siding will result in no cracking from the installation.

This in turn will provide a HardiePlank exterior siding job that will last for many years to come. This is the kind of siding job that you can expect from Texas Home Exteriors serving the greater southeast Houston east Texas metro area.

    I was just looking at your correctly nailing hardiePlank siding page as this is good advise for me. The stuff breaks so easily so I have to be more careful with the hardie siding, thanks.

      Donna, that is quite true that the Hardie – fiber cement siding is quite brittle and requires special handling procedures.
