19. Deck Trim

Horizontal trim can be installed around the perimeter of the deck, level with the top of the deck surface and with the top of the stair treads. Matching decking materials or cedar trim may be used. Deck trim adds a finished look to the decking and gives a point to bump the top of the deck skirt up to. Fasten outside mitres together tightly. Lap joints look best for inside corners.

Be familiar with composite decking expansion/contraction and cut trim accordingly.
