Joist Splitting. Any time that deck boards need to extend beyond a joist the upright pieces supporting the deck boards , the board has to be cut to share the top of the joist with the next piece in the row. When you are staggering joints across a deck, the joints must always meet up on top of a joist so that both pieces mount to the support.
With a staggered deck, each successive row is offset from the rows adjacent to it by one half of a board so that there are no long, uninterrupted vertical seems. Step 1 Lay your first board, starting in the corner of the deck, perpendicular to the support beams of your frame, along one edge of the deck.
Installing Deck Boards. Once the notches are cut, set the first board against the house wall. Make sure it goes all the way in and hits the sheathing. Secure the deck boards with 2 nails or screws where each board crosses a joist. 3 nails or screws may be necessary over the rim joists.

I used gray caulk between joints in my sunroom several years ago and it has held up well. I plan to caulk between the joints on my treated deck boards and use strips of foam cut from round pipe insulation foam and then caulk over the foam. The foam will keep the caulk in place till it dries.
SEAM BOARDS When a deck is longer than 20, an alternative to random butt joints is to run a seam board down the middle of the deck, perpendicular to the deck Close-up of deck seam. All deck board joints fall at the seam. Each seam is a sandwich made of an elevated vertical decking board with joists on both sides.
Sealing seams between outdoor composite decking. The seams are about 1/8 inch wide. Each deck board is one piece, 7/8" x 6" x 11 foot Ideally I'd like to apply some kind of sealer that is about as viscus as water so it would flow down the slope of the seams and into the small gaps that are currently allowing rain water drips

The next row do a 12' and 6' arrangement. You would run these along the 18' side. This will look better and may even be stronger.
Deck Area ft². If your deck is slightly out of square different widths , calculate results for both widths, and set out each end to suit. If necessary, adjust number of deck boards to match in both calculations, and see if different board gaps at each end of deck are acceptable, compared to equal gaps and cutting the last board at an angle.
