Do we nail or screw the decking boards?
The importance of screwing the decking boards cannot
be stressed enough. Many carpenters have taken to
nail gunning the decking boards to the joist structures.
This is a “Cheap and Nasty” way to affix the decking.
As the sub-
and heat, the nails are forced back up through the
Decking. Most coil nails used for decking do not meet Australian standards.
This process has a deleterious knock on effect:
Firstly the boards lift and the nails sit proud of the
decking, meaning that you essentially end up walking
on lose decking and a trip hazard. The nails then need
to be re-
The looseness of the decking boards also means that
on effect promotes movement within the sub-
which in turn resonates throughout the rest of the
deck like a spring; which in turn loosens more boards.
In essence, the problem is compounded every time you
use the deck.
Rot is an additional problem caused by the nail gunning
of the decks. When the nails are forced out by the
moisture, they leave a cavity within the timber. This
cavity fills from the inside out with the moisture in
within the sub-
the water in the joist outwards and thereby rot is avoided.
