<strong>CertainTeed</strong> WeatherBoards Fiber Cement Siding <strong>Installation</strong> <strong>Manual</strong><br />
Fiber cement shears typically have a flat side and a<br />
bevel side; consult the shear’s user guide for proper<br />
cutting technique. When using shears, take care to avoid<br />
delamination of the product layers at the edges.<br />
XXGuillotine Shears—Guillotine shears can cut cleanly,<br />
without distorting the edges of the siding.<br />

Cuts panels and trim up<br />

Cuts panels up to 5/16"<br />

Best Practice: For minimal dust and a clean cut, use a circular<br />
saw equipped with a polycrystalline diamond-tipped blade.<br />
XXCircular Saws—Circular saws create dust and, for<br />
that reason, should be used in outdoor, well-ventilated<br />
areas. Manufacturers include:<br />
Porter-Cable ® 743K<br />
Hitachi C7YAH 7-1/4"<br />
Makita ® 5057KB 7-1/4"<br />
Ridgid ® R3401 5"<br />
XXSaw Blades—<strong>CertainTeed</strong> recommends polycrystalline<br />
diamond-tipped blades to cut fiber cement<br />
siding because they outperform carbide-tipped blades.<br />
Fiber cement dulls carbide-tipped blades faster<br />
than polycrystalline diamond-tipped blades. You can<br />
expect to use five or more carbide-tipped blades per<br />
average residential installation, whereas polycrystalline<br />
diamond-tipped blades will perform satisfactorily for<br />
five to six residential installations.<br />
Exception: Use a carbide-tipped blade to cut 5/4<br />
and 4/4 fiber cement trim.<br />
Manufacturers include:<br />
Irwin ® Marathon ® PCD-7-1/4 -10" -12"<br />
Malco ® 7-1/4" –10"–12"<br />
Hitachi 7-1/4"–10"–12"<br />
DeWalt ® 7-1/4"<br />
Tenryu Board Pro -7-1/4"–10"–12"<br />
Bosch 7-1/4"–10"<br />
NOTE: Do not cut wood with a polycrystalline<br />
diamond-tipped blade because wood will dull<br />
the blade.<br />
XXMiter Saw—When equipped with a polycrystalline<br />
diamond-tipped blade, a miter saw will cut up to five<br />
pieces of fiber cement siding at a time.<br />
XXJig Saws—Jig saws equipped with polycrystalline<br />
diamond-tipped blades are typically used to cut service<br />
openings, curves, radii, and other irregular shapes.<br />
XXHEPA Filter Vacuum Attachments for Power Saws—<br />
When cutting fiber cement, we highly recommend<br />
using power saws equipped with HEPA filter vacuum<br />
attachments. When attached directly to power tools,<br />
vacuums equipped with HEPA filters minimize the<br />
amount of respirable dust the operator is exposed to.<br />
Manufacturer’s include:<br />
◆ Fein – Turbo 2<br />
◆ Porter-Cable<br />
◆ Festool<br />

X Drills—Masonry bits work best when drilling holes in<br />
fiber cement siding and trim.
