Building Decks
4. Post/beam connectors (for single beam):
# of posts = connectors
Miscellaneous
1. One quart end-cut solution.
2. One gallon water repellent for every 150 sf
of decking surface.
Also, remember to add fascia, pier blocks, con-
crete/post brackets, angle brackets, concrete and

Getting Down To It
Six Steps to a Basic Deck
Deck Support
1 Install the Ledger Board
2 Position Your Footings
3 Install Your Posts
Substructure
4 Attach the Beam
5 Install Your Joists
Decking
6 Lay Down Your Decking
Before beginning to build a deck, you may
need to apply for a permit – check with your
local building department for this and other
code considerations.
Also see Consumer and Warranty Information
Section before beginning any construction.
Post spacing:
(deck length - 2 X cantilever) ÷÷ # of posts
= ft.
3. Finally, determine the proper trimmed length of
the post.
Length of post: deck height + depth
post will be buried - 1
1
/2"
=
ft. in.
Note: The untrimmed post must be at least this long, and
should be longer to allow a margin for error.
Ledger Board
1. You will need one ledger board. Below, deter-
mine its size and length.
Ledger size (same
as joist size): =
by
Ledger length:
deck length - 3" =
ft.
Hardware *(Galv ASTM A 153 [Fasteners]
and ASTM A 653 Class G [Connectors])
1. Joist hangers with nails:
#of interior joists =
2. Bolts (1/2” x 4" lag w/washer)*:
For ledger:
# of interior joists X 2 =
For double beam:
# of posts X 4 =
Total bolts =
3. Nails*:
For joist: # of joists X 5 =
For single beam: # of posts X 12 =
Total 16d nails =
For decking*;
with 16" joist spacing:
6(deck width in inches ÷ 11")
X[(.75 deck length in feet) + 1] =
with 24” joist spacing:
6(deck width in inches ÷ 11")
X [(.5 deck length in feet) + 1] =
Total 12d nails =
Note: We highly recommend using corrosion-resistant
deck screws. Do Not Mix the use of Hot Dipped Galva-
nized and Stainless Steel. Aluminum should not be used
in direct contact with EXTRAGREEN™ treated wood.
