Can I screw into Hardie board?

Last Updated: 31st March, 2021

Manufactured by James Hardie, HardiePlank siding is a fibrous cement-based product. HardiePlank is available as ready-to-paint or with a color layer. Although the siding does not require drilling pilot holes, you may need to run wire or cable through the siding, necessitating drilling a hole.

Thereof, can you screw into hardiplank?

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.

Beside above, how do you attach Hardie board? 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.

Similarly, can I screw into cement board?

Cement board attached to plywood or similar underlayment will hold with only 1 1/4-inch screws; for thick or heavy metal fixtures, use 1 5/8-inch screws. In general, 1 1/2-inch galvanized nails will hold the board firmly in place. Even if you use this extra adhesive, you should still apply the nails or screws.

Where do you screw Hardie board?

Avoid fastening in a straight line. Fasten HardieBacker boards with proper fasteners (as listed in “Materials Required”) a maximum of 3 in on center around the perimeter and 6 in on center in the field. Keep fasteners between 3/8 in and 3/4 in from board edges and 2 in in from board corners.

Should hardiplank be caulked?

Hardie no longer recommends the caulking of any joint in their lap siding (colorplus or primed). Deterioration of the caulking in the joint has become a maintenance issue for home owners over time. Joint flashing is recommended for all hardie lap siding now.

Do you need special screws for cement board?

To attach the cement board to the studs, you'll need special 1-1/4 in. cement board screws (see Fig. B). These screws have a coating to resist corrosion, a special wide head with cutting flutes and hi-low threads for a strong grip. If you can't find them at a home center, call tile specialty stores.

How do you cut a hole in Hardie board?

You can also cut holes using a jigsaw with a metal-cutting blade or a drill fitted with a carbide-grit hole saw. When using a jigsaw to cut a round or square hole, start by drilling a hole through the backer board with a 3/8-inch-diameter masonry drill bit. Then insert the jigsaw blade into the hole and start cutting.

How do you attach Hardie plank siding?

The best way to attach to Hardie Plank siding is by using nails or screws. To avoid cracking the siding, pilot drill the siding first, using drill bit a little smaller than the nail or screw. And to make the sure the hole you are forming doesn't leak, caulk the hole before driving in the fastener.

Do you have to tape cement board before tiling?

2 Answers. The thinset and mesh tape are to strengthen the seams. If you are going to tile over the cement board, you should tape the seams. If you just want to leave the corners untreated that will probably be fine, because that seam won't split the center of a tile.

Do you Thinset under Hardibacker?

You do need the thinset under the backerboard, you do need the 1/8" gaps between the sheets (and 1/4" around the perimeter) and you do need the tape and thinset on the seams. If your tilesetter refuses to correct his mistakes, ask him to leave, and be firm.
