CUTTING HARDIEBACKER

CEMENT

BOARD

WITH HYDRODEFENSE

™

TECHNOLOGY

• Use a straight edge as a guide to score the board’s face and snap upward along

the score line. We recommend using a carbide tipped scoring knife, but a utility

knife may also be used. The use of shears (manual, electric or pneumatic) is also

acceptable.

• For cutouts and small holes, score around perimeter and break out from the face

side with hammer.

• Using high-speed power tools (e.g. saws, grinders, etc.) to cut James Hardie

products may generate excessive silica dust.

NEVER cut James Hardie products indoors with these tools.

ALWAYS cut outside with adequate ventilation and/or dust collection

equipment in accordance with OSHA regulations.

To further limit respirable silica dust exposures, wear a properly-ﬁtted NIOSH

approved dust mask or respirator (e.g. N-95 dust mask) in accordance with

applicable government regulations and manufacturer instructions.

• NEVER dry sweep – Use wet dust suppression methods, sweeping compound, or

use a vacuum to collect dust.

WALL INSTALLATION

1 | Ensure the framing is structurally sound

• Framing shall comply with local building codes and ANSI A108.11.

• Use a minimum of 2 in. x 4 in. wood studs or 20-gauge metal studs, which

must be straight, properly aligned and spaced a maximum of 16 in. on center.

• In tub and shower enclosures, ensure that the framing is adequately

reinforced at the corners and ends.

SPECIFICATIONS

• Thickness: 0.42 in.

• Dimensions: 36 in. x 60 in.

• Weight: 2.6 lb/sq. ft.

• Application: Walls, ﬂoors & countertops

2 | Determine the HardieBacker

Cement Board with HydroDefense

™

Technology layout

• Boards may be installed vertically or horizontally.

• Edges of the board parallel to framing must be supported by a structural

framing member.

• Score and snap boards to required sizes and make necessary cutouts.

3 | Attach the HardieBacker

Cement Board with HydroDefense

™

Technology to framing

• HardieBacker

Cement Board with HydroDefense

™

Technology has internal

waterprooﬁng treatments. Does not require a moisture barrier.*

• Attach the HardieBacker

Cement Board with HydroDefense

™

Technology.

• Provide a 1/4 in. clearance gap between the ﬂoor, tub or shower receptor

base and the cement board.

• Do not place cement board into the shower pan mortar bed.

• Fasten the product with speciﬁed nails or screws (as listed in “Materials

Required”) a maximum of 8 in. on center at all supports.

• Keep fasteners 3/8 in. from board edges and 2 in. in from sheet corners.

• Set fastener heads ﬂush with the surface, without overdriving.

4 | Joints and Penetrations

• Seal ﬁxture penetrations, plumbing penetrations and abutments to dissimilar

materials with ﬂexible sealant (see “Materials Required”).

• Fill all joints with mortar (see “Materials Required”). While mortar is still

workable, embed minimum 2 in. wide high-strength alkali-resistant glass

ﬁber tape in the mortar and level.

• Do not use all-purpose joint compound or paper tape.

• When complete waterprooﬁng is required, seal all joints, edges and fastener

penetrations with a liquid waterprooﬁng membrane. Follow the liquid

waterprooﬁng membrane manufacturer application instructions.

* Some application areas may require additional waterprooﬁng. Refer to local building code requirements.
