In what direction should decking boards be placed (horizontal / vertical) compared to the deck? The boards are usually placed horizontally perpendicular to the adjacent wall. This choice is above all aesthetic, but it also important to be sure that the direction of the boards does not hinder water drainage.
Regarding this, does it matter which way you lay decking boards?
A board that is correctly installed right side up (or bark side down) will form a crown and allow water to run off the edges. If the board is installed wrong side up (or bark side up) it will curve up on the edges when dry and water can gather and sit in the cup. That is a recipe for wood rot and problems.
Similarly, which way should porch decking run? The main thing is that the boards run perpendicular to the joists, either at 90 or 45 degrees. Your situation is one of aesthetics and is your preference. Your real issue will be with the joists.
Thereof, should decking be ribbed side down?
However, every decking timber manufacturer will tell you: the proper way to install a board is ridge side down. The ridges, they say, were designed to let air circulate underneath the boards. This, according to them, prevents the buildup of moisture and, consequently, of mould.
Should deck boards be parallel or perpendicular to House?
Well, normally girders are parallel to the house, the joists are perpendicular and the deck boards are parallel. This is because the ledger acts as the a girder against the house supporting the joists. If you run the deck boards perpendicular to the house, then the joists need to be parallel.

Should you flip deck boards?
You bet you can flip them. There’s no harm in doing so. While you’re at it, be sure to clean off any debris from the top of the support joists and check for rot at those locations. When reinstalling the decking, keep at least 1/4-inch spacing for ventilation and easy cleaning in the future.
Should you pre drill deck boards?
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.
How many nails should be on a deck board?
The basic rule of thumb here is 350 screws for every 100 square feet of deck surface for standard 6” wide boards (5.5” actual width) and 16” spaced joists. If you aren’t using these standard sizes, use an online deck calculator to determine how many you’ll need.
Can 2×6 be used for deck joists?
2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decks use 16″ on center spacing for joists. Most decking is not strong enough to support longer spans than 16″.
What is the gap between decking boards?
SPACING BETWEEN DECK BOARDS Ensure there is a minimum gap of 5-6mm between each deck board.
How do I keep my deck boards from warping?

What are grooves in decking for?
Deck boards with grooves are designed to channel water away from the deck. To help with drainage, they should be fitted with a slight tilt in the direction of the grooves.

Why do decking boards have grooves?
The grooves or reeds on a decking board are not there as an anti-slip measure, nor are they there to make your decking look prettier. They are designed to allow for airflow underneath the boards to stop moisture and mould build up.
Should you 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.
Is composite decking slippery when wet?
Wood is more likely to have smooth spots created by wear; such spots may be slippery when wet. Most brands of composite decking have textured finishes to make them slip-resistant. Water and ice accumulation from rain and snow may create slippery conditions on any deck surface.
Can you lay decking on grass?
If you’re laying your deck straight onto the ground, cover the area with a layer of weed control fabric. Lay the decking on the grass in your decided design and leave the right expansion gaps between boards (5 to 8 mm along the length of timber boards, and 3 mm along the ends).
