Q: Are there any special tools required for installation?
A: No. we recommend that you pre-drill screw holes when installing CorrectDeck Classic and to use a narrow shank, #1 square drive bit when installing Fastenator clips for our Channeled decking.

Q: How do I cut CorrectDeck?
A: Use a carbide-tipped combination blade. When ripping, use a ripping blade, which has deeper notches to clear shavings.

Q: The CorrectDeck products have a Limited Lifetime Warranty. What do I do if the substructure needs replacing?
A: 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 applied the CorrectDeck product), remove the CorrectDeck boards, replace the complete substructure and reattach the CorrectDeck boards.

Q: How Do I Make an ADA Compliant Handrail?
A: Rout a Groove in DCL 2x4 and mount as shown.

Q: What type of framing lumber should I use?
A: We have seen a large decline in the quality of treated wood in the marketplace in the last 3 years. 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. 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.

Q: Why do my Grey boards have a brown cast?
A: This is an artifact of the brownish color of the recovered wood fiber used to make the product. This exposed wood fiber in standard CorrectDeck weathers to a gray color quickly, and the brown or reddish cast fades away. CorrectDeck CX has a co-extruded layer that encases the wood fibers and therefore eliminates this effect.

Q: What type of fastener should I use for the Channeled Series?
A: 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.

Q: What is the shrinkage rating per board?
A: We recommend, if it's cold out (below 40ºF), 1/8" gap end to end; if it's hot, no gap. Other than that use a 16th end to end. See our installation instructions to see how to back cut and see no gap. CorrectDeck expands and contracts less than other brands of composite decking. There is no width shrinkage or expansion.

Q: What sort of railings do you recommend?
A: CorrectDeck RapidRail is a mortised rail system that matches our standard CorrectDeck decking and installs in a fraction of the time it takes to install other composite rails. We also offer dimensional composite lumber (DCL) that can be used for more conventional railings. A DCL connector allows for easy connection to a newel post or wall.

Q: Does CorrectDeck come with a warranty?
A: Yes, our limited lifetime warranty provides added protection and piece of mind.

Q: How far can the decking boards span?
A: Joists should be spaced a maximum of 16” on-center for typical installation where the deck boards are 90° to the joists; 14” on-center for boards installed 45° to the joists; and 12” on-center for boards installed 60° to the joists.

Q: Can CorrectDeck create a watertight surface?
A: No, it should not be installed in such a way that water will pool on it.

Q: Can I cantilever/overhang the material over the edge of my deck?
A: Yes, Overhang should not exceed 4 inches.

Q: What glue works well with Correctdeck?
A: 3M Scotch-Weld Acrylic Structural Plastic Adhesive DP-8010.

Q: Can I router the boards?
A: Yes, like wood, it routs easily. Use a ¼” round bit to match the factory edge (Classic style).

Q: What spacing is required between the boards?
A: 1/8” Please see our installation instructions for more information. The Channeled hidden fastening system and Fastenator clip automatically establishes the required gap.

Q: How do I dispose of CorrectDeck lumber? Can it be taken to a landfill?
A: Yes. CorrectDeck does not any contain toxic materials and can be disposed with normal construction materials.

Q: What should I do with my scraps?
A: The best thing to do is use them in home projects, such as a compost bin, benches, shelves, sandboxes, raised bed edging, or planters (there are no chemicals to damage plants).

Q: How do I prevent weed growth?
A: A high quality landscape fabric under the deck, covered with pea gravel or washed stone, is a good idea to prevent weed growth.

Q: Can I put down CorrectDeck over a concrete patio?
A: You may install CorrectDeck over an existing concrete slab. There are a few things that you need to do.

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.

Q: Should I be worried about installing your product in cold weather?
A: CorrectDeck was designed, developed, and is manufactured here in Maine. It's made for the coldest climates. That is why the groove has the overhang and deep engage - to keep ice and snow out. The clips are high-impact polypropylene copolymer. The only cold-weather caveat is not to install with a pneumatic stapler when temperature is below 40 F.
