From what I have read, I made a rookie mistake and started installing my composite decking from the inside edge out when I should have started the other way.

That said, I now have 3" remaining on the outside edge and my boards are 5 1/2" wide. Does anyone have any suggestions on completing the project? Unfortunately, it's not as easy as adding another rim joist due to my steps. I have included some pictures.
Thanks in advance.

Rip cut the plank. then place a grove cut along the side, for a tongue to fit.

Remove 1/2 the installed ones, put the narrower one in the middle, replace the other planks and call the narrow one an ACCENT piece. :devil3:

Or add a second rim joist, and maybe a third.

Your outer board should not have a groove in it (like the board on the riser in you pic). You only options at this point are to rip it to the width you want and paint the edge with the touch-up paint they sell. If you do have (or get) a non-grooved board, you can still rip it, then flip it around so the cut edge is facing in. You can cut slots for the mounting clips using a bit and router.

You could cut it and do the round over with a router.

This is a good example of why I always run my joist wild and just start decking.

I start decking with a full board from the house out until I'm a couple of courses from the end. At that point I'll snap a line, cut the joist and install the rim so I'll end up with a full width board on both ends.

You still have time to do that, you may have to remove one course though to give you enough room to cut the joist back.

Btw, you can get those deck boards with the groove on only one side. You use those for the last/finish course.

That's cheating, I like it. :wink2:

Similarly, I start at the far side and work toward the house so that the ripped board is against the house.

You can purchase a square edge board that wraps the cap all the way around. Route the cut edge and buy some color matched paint. Composite takes paint extremely well. You can also use a biscuit cutter to groove the cut edge. Or just use color matched screws (fastenmaster) on every other joist. They are not a bad look, imo.

Or put the cut edge out then you can use the grooved board.
