Will I need to replace my CorrectDeck deck
boards if the substructure needs to be replaced?
In this case, you will not need to purchase
new CorrectDeck decking materials. If the
substructure is deteriorating and needs
to be replaced, all you will need to do
is unscrew the fastenators (or the screws…depending
on how you originally installed the CorrectDeck
product), remove the CorrectDeck boards,
replace the complete substructure and reattach
the CorrectDeck boards.

What type of lumber should I use for framing
my project?
We always suggest that our customers choose
KDAT stamped framing lumber. This wood will
be straighter and will also be lighter and
easier to handle, and won't shrink and expand
as much during and after the deck project.
The reason why we make this suggestion is
that we have seen a large decline in the
quality of treated wood in the marketplace
in the last 3 years, and it causes us frequent
complaints and problems. The primary change
has been a cost-saving move to skipping
the KDAT (kiln-dried after treatment) step.
This results in wood that twists and shrinks
a lot after the deck frame is nailed together;
resulting problems are often blamed on the
decking surface.

What type of fastener should I use for the
CorrectDeck Channeled boards?
The CorrectDeck Fastenator can be applied
with staples or trim head screws. Pre-loaded
Fastenators (with #7 x 2 ¼”
trim head screws) can really speed up installation
time.

What is the shrinkage and expansion rate
for CorrectDeck boards?
CorrectDeck expands and contracts less than
most composite and PVC decking due to its
polypropylene based composition. Use our
Deck
Spacing Calculator to address end to
end gapping.

What railing do you recommend?
CorrectDeck offers two types of railing
options; RapidRail and DCL Railing that

composite as our decking products. See RapidRail

Can CorrectDeck be installed over a concrete
patio?
You may install CorrectDeck over an existing
concrete slab. However, there are a few
things that you need to do prior to installation.
1. CorrectDeck requires a minimum of 1 1/2"
spacing under the decking. You can use 2x4
laying on the side as the frame and stringers.
The more air flow and water drainage spacing
the better.
2. Due to the rigidity of CorrectDeck, when
you are installing over concrete you will
need to make your frame "Floating".
Do NOT anchor the frame into the concrete
in any way. The reason for this is because
with the small air space under the deck,
any ice and water that accumulates under
the deck will want to expand and push on
the bottom of the deck. A "Floating"
frame will allow for the deck to move without
putting excessive pressure on the deck boards
causing the deck to fail.
3. Account for proper drainage. Keep in
mind that water and possible debris from
trees, dirt, grass etc. will find its way
under your deck. proper water flow channels
should be put in your framing to allow that
to come out.

What should I do with my CorrectDeck scraps
and what is the proper way to dispose of
them?
CorrectDeck scrap pieces can be used for
a variety of homes projects such as benches,
shelves, planters (there are no damaging
chemicals to plants), sand boxes, raised
bed edging, or compost bin. CorrectDeck
does not provide any installation instructions
for any scrap applications. CorrectDeck
is not recommended for any structural applications.
CorrectDeck does not contain any toxic material
and can be disposed with normal construction
materials.

What spacing is required between CorrectDeck
boards?
1/8” spacing is required between CorrectDeck
boards, but the Channeled hidden fastening
system of installation automatically establishes
the 1/8” gap. Use our Deck
Spacing Calculator to address end to
end gapping. Watch

Can I router CorrectDeck Classic boards?

router bit at our online
store.

Can I overhang CorrectDeck over the edge
of my deck?
CorrectDeck allows for overhang, but this
should not exceed 4 inches.
Back to top ^
Can CorrectDeck create a watertight surface?
CorrectDeck is not designed to be installed
in a way that water would pool on it. 1/8”
gapping is needed for proper drainage between
boards. If you want to create a dry area
beneath your deck for storage or extra living
space, we recommend using Rain
Escape Under Deck Drainage System.

Is there a way to prevent weed growth from
under CorrectDeck?
One suggestion for use to prevent weed growth
from under your CorrectDeck would be to
use a high quality landscape fabric under
the deck, covered with pea gravel or washed
stone. CorrectDeck does not offer any of
material to prevent weed growth from under
you deck; please visit you local home &
garden store for more information.

24” on center depending on the application.
See CorrectDeck span
