• Where the walls are higher than two storeys, it is necessary to provide a horizontal flashing at the second floor level to drain the cavity.

• The installation of smoke chimneys, pipe penetrations and other fixtures etc. must not track moisture into the wall or restrict the drainage of moisture to the exterior.

required.• Pruning back vegetation which is close to or touching the

building as well as ensuring the NZBC ground clearance requirements are maintained especially where gardens are concerned.

• The clearance between the bottom edge of the Stria Cladding and the finished/unfinished ground must always be maintained.

*Do not use a water blaster to wash down the cladding.

* In extreme coastal conditions or sea spray zones, wash every 3-4months.

** Refer to your paint manufacturer for washing down and recoating requirements related to paint performance.

Hole-FormingFor smooth clean cut circular holes:

• Mark the centre of the hole on the sheet.

• Pre-drill a ‘pilot’ hole.

• Using the pilot hole as a guide, cut the hole to the appropriate diameter with a hole saw fitted to a heavy duty electric drill.

For irregular holes:

• Small rectangular or circular holes can be cut by drilling a series of small holes around the perimeter of the hole then tapping out the waste piece from the sheet face.

• Tap carefully to avoid damage to sheets, ensuring that the sheet edges are properly supported.

James Hardie recommended safe working practices

CUTTING OUTDOORS

1. Position cutting station so wind will blow dust away from the user or others in working area.

2. Use one of the following methods based on the required cutting rate:

BEST• Dust reducing circular saw equipped with HardieBlade™

Saw Blade and HEPA vacuum extraction.GOOD• Dust reducing circular saw with HardieBlade™ Saw Blade.

SANDING/REBATING/DRILLING/OTHER MACHINING

When sanding, rebating, drilling or machining you should always wear a P1 or P2 dust mask and warn others in the immediate area.

IMPORTANT NOTES

1. For maximum protection (lowest respirable dust production), James Hardie recommends always using “Best” — level cutting methods where feasible.

2. NEVER use a power saw indoors.3. NEVER use a circular saw blade that does not carry

the HardieBlade™ logo.4. NEVER dry sweep — Use wet suppression or HEPA vacuum.5. NEVER use grinders.6. ALWAYS follow tool manufacturers’ safety recommendations.

P1 or P2 respirators should be used in conjunction with above cutting practices to further reduce dust exposures. Additional exposure information is available at www.jameshardie.co.nz to help you determine the most appropriate cutting method for your job requirements. If concern still exists about exposure levels or you do not comply with the above practices, you should always consult a qualified industrial hygienist or contact James Hardie for further information.
