Working
Instructions
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.
Cutting
HardiFlex
sheets can be cut using any of the following methods:
SCORE
-AND- SNAP
"Score -and- Snap" is a fast and efficient method of cutting
using Scoring knife.
Procedure:
-
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
Procedure:
-
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
Prcedure:
-
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
Procedure:
-
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. back to top
