How to install hardie board

Hardie board comes with a 30-year manufacturer’s warranty, but that means you need the nails to last at least that long too. James Hardie recommends that nails be hot dip galvanized (at a minimum) or stainless steel (as a best practice).

Fastening Siding

Fiber cement siding can be nailed by hand or with a pneumatic nailer. It can also be attached using corrosion resistant screws. Use hot-dipped galvanized or stainless steel nails. Nails should penetrate through the sheathing and at least 1” into studs.

Fiber cement siding should be installed over plywood, OSB, or sheathing. Be sure that the siding installed is dry. Building codes will usually require installing siding over water-resistant barriers and nailed into the studs every 16 or 24 inches.

NAIL TYPE:

Fasteners must be corrosion resistant, galvanized or stainless steel. Electro-galvanized nails are acceptable for use with James Hardie Siding Products, but may exhibit premature corrosion. James Hardie recommends the use of quality, hot-dipped galvanized nails.

Fiberboard cement siding can be hand-nailed, but because it’s so much harder and more brittle than wood, you have to predrill holes near any edge. You can save yourself a bunch of time by using a pneumatic coil siding nail gun.

If you mean “can you put screws into James Hardie siding” the answer is yes. Otherwise, you may have landed on the wrong website. James Hardie boards can technically be drilled like wood, but it is best to use a masonry bit to drill this tough fiber-cement board.

To what surfaces will Command™ Products stick? Painted, stained or varnished wood, glass, tile, painted cinder block, plaster, metal, and painted wallboard. The Outdoor Product line is not recommended for use on rough surfaces, such as cement board, brick or rough-sawn wood.

A. Absolutely not. Hardieplank weighs 2.3 lbs per square foot. That is about the same weight as 5/8″ thick Sheetrock.

Fiber cement siding costs $6 to $13 per square foot to install for Hardie board siding and labor. The average cost to install fiber cement siding is $8,000 to $24,000 for a 1,500 to 2,000 square foot home.

Tom: Yes. It’s a perfect application for it because T-111 is nothing more than a textured plywood, and a plywood makes a great sheathing. Get rid of the rot. Get some regular CDX plywood, the same thickness as your T-111, fill in the gaps, put the Tyvek on there, put the Hardie on there.

As originally designed, T1–11 siding was made from Softwood plywood. The addition of OSB was made as a cost-cutting measure. But the best T1–11 siding is still made of softwood plywood. OSB is much more susceptible water soaking in and swelling the sheet, especially at the edges.

Normal siding needs to be repainted once every 5 to 7 years, but James Hardie siding is made from fiber cement and doesn’t need to be repainted quite so often– a paint cycle can last as long as 12 years, and the paint prefinished James Hardy siding is warranted for 15 years.
