| Material Requirements |
Start by calculating the square footage of your deck surface. Once you know
this number, take it and divide by 5.5 for 12' planks, 7.33 for 16'
planks and 9.167 for 20' planks (These numbers represent the total square footage
for the 12', 16' and 20' Azek Deck planks). When calculating the amount of decking
you will need, it is recommended that you add roughly 3% to the total for a scrap
factor.
Example:
Length x Width = Total Square Footage
Square Footage divided by 5.5(12'), 7.33(16') or 9.167(20') =
Planks Needed (Round up)
Planks Needed + 3% (Scrap Factor) = Final Number of Planks Needed (Round up)
NOTE: You will need approximately 3.54 fasteners per 1 square foot of decking when using
16" centers. You will need approximately 4.64 fasteners per 1 square foot of decking when using
12" centers.
Remember that if you are attaching the planks at an angle, you will likely generate more scrap from cutting,
so more material may be required. A drawing to scale may help you determine how much more plank material
will be required. |
| Fasteners |
Color-matched stainless steel fasteners are available. There are many types of fasteners available
including those designed for composite decking, which may be used. When selecting an alternative fastener, please
insure that the following requirements are met: Stainless Steel Composition; Minimum Screw Size: #7; Minimum
Length: 2¼". |
| Tools Required |
Azek Deck can be installed with a minimum number of readily available tools. There are,
however, many other tools available to contractors that can provide even greater efficiency and ease of installation.
The following chart shows some of the basic tool requirements:
| |
Circular Saw |
|
Cordless Driver |
|
Carpenter Square |
|
| |
Chalk Line |
|
Spacing Tools |
|
Tape Measure |
|
|
A power miter saw and jigsaw can also be very helpful during installation. Use the jigsaw to cut around obstructions such as
posts. Self-feeding screw guns can be used to drive screws properly with minimal physical effort. It is recommended that you
use a circular saw with a fine-toothed carbide-tipped finish trim blade or a 20-grit diamond blade to achieve the neatest cuts.
Safety glasses should be used during the entire installation process. |
| Preparation |
Proper joist spacing is required for proper installation. Check to make sure that the joist spacing on your
substructure does not exceed 16" center-to-center (12" for commercial applications). If tearing off existing decking material
first, check to see that all joists are level, structurally sound and that there are no nails or screws protruding.
If you plan to run decking planks on a 45-degree angle such as a herringbone pattern, the joists should not exceed 12" center-
to-center. As always, all supports for attaching railings should be in place before installing your planks. Azek Deck products
should not be used for railing supports. |
