“Many
structural failings stem from improper nailing”
To
put it simply, “If you install the nails too near the edge or end of
the board it will split—if it splits it is weak”.More nails than
necessary will not mean the deck will be stronger. You can only install
so many nails before the wood splinters.
Larger
nails aren’t necessarily better either; We use 31/4 “ nails for Cedar
onto a pressure treated frame. If pressure treated lumber is
particularly dry we will often use 3 ½”.
When
fastening 2x beams to 6x6 columns we typically notch them in and nail
as shown in illustration. We then add a ¾” hole and carriage bolt to
secure it.
·
Try to install the decking long—leave something to cut off after. Once
you have installed all the decking, you can cut off the extra in a
single straight cut.( Saving time also).
·
For spacing we aim for 3/16” between the boards. Start one board by
running a chalk line and then straightening to the mark. This ensures
the rest of the decking is straight. We use a pair of scratch awls and
a flat bar or bow wrench to pull the boards in and out as it’s nailed.
There are specialized tools available for this purpose if you want to
spend the money. The spaces between the boards will grow to about ¼”
after the lumber dries giving a uniform look and allowing the joists to
dry.
·
Try leaving the joists long until all but 3 or 4 boards are installed.
You can then measure the amount of distance required to end with a full
board.
