How do you install decking with hidden fasteners?

Last Updated: 10th June, 2020

Start on one edge of your deck with a single grooved board. Set it into place so that it's flush with the edge, then insert a hidden clip into the groove. Slide a second grooved board along the first, pre-drill the hole, and drive a screw into the fastener between the boards.

Secondly, is it better to nail or screw deck boards? kkeilman Answers: Screws are a "superior" fastener over a nail (they have far superior tensile strength)—especially if you're talking about screwing down decking. Using your deck example—you should use nails to attach the joists to the deck framing but use screws to fasten down the decking itself.

People also ask, what is the best hidden deck fastener system?

Cortex Hidden Deck Fasteners. The Cortex Hidden Fastening System is the fastest, easiest way to hide fasteners in composite, wood, and PVC decking boards. Cortex offers a strong connection between the deck board and joist. It hides fasteners across the entire deck, first and last board, perimeter and stairs.

What is the gap between Trex boards?

Secure with screws from bottom through blocks and into stair treads. NOTE: Maximum spacing of deck boards using Hideaway system is 450 mm on center. Fasteners provide 6 mm gap when installed correctly.

What length deck screws should I use?

Most decking screws are 8-gauge and, while 2 1/2 inches is the minimum length needed to hold decking boards to the joists, 3-inch screws are commonly used to provide extra holding power against the upward pressure of shrinking or warping boards.

Can you use stainless steel screws in pressure treated wood?

Corrosion-resistant stainless steel screws, nails and bolts in grades 304 and 305 can be used for copper-treated wood in most areas, while grade 316 should be used in coastal areas. But stainless steel fasteners can cost five to 10 times more than similar galvanized fasteners.

How do you hide the ends of a composite deck?

One way to hide the ends is to install a border around the perimeter of the deck. While that can add visual interest to solid-color decking boards, it requires considerable blocking and adds to the project time line and overall cost. And when used with multichromatic decking boards, borders are almost a distraction.

How do you fill screw holes in composite decking?

Fill small holes, using a putty knife, with a mixture of fine composite board shavings and silicone caulk. The consistency of the mixture should be thick enough that it will not seep out of the bottom of the hole. Match the color of the caulk to the deck boards.

How do you run deck boards perpendicular to a house?

If you run the deck boards perpendicular to the house, then the joists need to be parallel. Then your ledger acts like joist, rather than a girder. In order for the deck to be strong what would have been your outer most joists running perpendicular need to become girders that act like ledgers.

Can you use deck screws on composite decking?

You can screw or nail composite decking boards just like wood ones. Three-inch decking screws are the best fastener choice; they sink a secure distance into the joists and won't back out like nails. There's little danger of splitting the boards when driving them, so you don't need to pre-drill.

Can I build a deck directly on the ground?

Building an 8-by-10-Foot Floating Deck
Floating decks can be set directly on the ground or, preferably, a bed of gravel. But it's best to support the deck on concrete blocks. This keeps the wood off the ground and away from moisture so the wood stays drier and lasts longer.

How do you fasten composite deck boards?

Composite deck boards are fastened together with two-sided metal fasteners. These fasteners are placed between the boards on a joist, then driven into the previously mounted deck board end with a hammer. A deck screw is then driven through the fastener and into the joist to anchor it permanently.

Should I pre drill holes for deck screws?

Pre-Drilling Holes: The main benefit of pre-drilling holes for deck screws, or any screws, is simply preventing the wood from splitting. Often this is the only way to prevent splitting when driving screws (or nails) close to the end of a board.

Should you countersink deck screws?

If you are face-driving deck screws, it is acceptable to “self-countersink” them. Some deck screws even have a little cutter head built into the screw, to facilitate countersinking.

Can you use composite deck screws on pressure treated wood?

Not really. For wood decks (pressure treated and cedar) it depends on whether or not you choose to screw or nail the decking down. The head of these screws are coated to match the most popular tones of composite – including grey, sand, red and dark brown.

What are the best screws for decking?

Galvanized screws work well with pressure-treated decking, while Redwood or Western Red Cedar decks are usually built with stainless steel screws to prevent staining around the screw heads.

How long should screws be?

The most important factor in screw selection is length. The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4.

Does Trex decking warp?

Your composite deck may not warp, but it can sag and buckle. Most sagging is caused by improper spacing between the joists when it is installed. Composite decking is fade resistant, but it may fade over time in strong sunlight. Composite decking will get lighter in color tone as it fades.
