Note: Cutting cement fibreboards
Cement fibreboards can be cut by scoring (scratching a deep mark)
across the board and then by snapping. Score repeatedly against a
straight edge to a depth of about 1/3 of the board thickness and then
snap (bend) the board upwards to achieve the break.
You can use a
purpose-made score and snap tool that has a hardened scoring tip or
similar type tool.
Also hand or pneumatic guillotine (shears) can be used.
There are also other ways of cutting cement fibreboard, but this method produce the least dust.
Note: Nailing cement fibreboards
Use 50mm (2") galvanized flathead nails. Only nail where there is
something solid beneath the board such as a stud or a rafter.
Nail where the boards overlap. Do not nail closer than 20mm (3/4") from
the end of a board. Pre-drill any nail hole that is closer than 50mm
(2") from the end of any board.
