Handling Storage

HardiFlex should be carried on the edge and stacked in a smooth, level surface.  Edges and corners should be protected from chipping.  To ensure optimum performance, store under cover and keep dry prior to fixing and coating.  If the sheets should become wet, allow to dry before fixing is commenced.

Safe Working Practices
Breathing in the fine silica dust liberated when working with products such as fiber cement, clay and concrete is hazardous.  Always work safely when working in dusty working areas.

When using power tools or abrasive hand tools on fiber cement sheets wear approved personal protective equipment.  

  • Use face masks

  • Use safety goggles

  • Celan up, wet down or vacuum

  • Disposal containment of dust

HardiFlex sheets can be cut using any of the following methods:

"Score -and- Snap" is a fast and efficient method of cutting using Scoring knife.


  • Preferably score from the face side of the sheet. 

  • Position straight edge along the line of the cut.

  • Score against straight edge and repeat the action to obtain adequate depth for a clean break - normally one-third of the sheet thickness.

  •  Snap upwards to achieve break.

  • Clean up edges with a rasp or 40 grit sand paper. 

Hole Forming
For 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 appropriate diameter with a hole saw fitted to a heavy duty electric drill.

For small irregular holes


  • Small rectangular of circular holes can be achieved by forming 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.  Rough edges can be cleaned up with a rasp or 40 grit sand paper.

  • Do not form holes through the sheets with cold chisels, heavy hammers or any other "aggressive" methods.

  • Such forceful methods will damage sheets and may cause other problems at a later date

For Large Holes or Openings


  • Deeply score around the perimeter of the opening.

  • Form a large round hole in the centre using the method previously described.

  • Saw cut from the center towards the corners of the opening.  A jabbing action is efficient.

  • Tap waste pieces from the face side and if necessary, clean rough edges with a rasp or with 40 grit sand paper.  Radius corners with a half round rasp to eliminate any stress points.
