If you live in a humid climate or a location that has many freeze-thaw cycles, you need more durability. Leaving bigger gaps and avoiding the trapping of water also helps.
If the deck will receive intense heat from the sun, remember that UV rays generally degrade plastic material. Nearby trees, a pergola or other type of sunscreen is not only nice for the guests, but will extend the life of your material as well.
There are so many great materials to choose from. You can choose natural wood for the character that goes with it. This deck uses composite material chosen for durability and ease of workmanship.
After cutting the ends of the boards, chamfer the edges for a smoother look and a comfortable feel.
When a flat surface is required under your decking, drill large holes to let the rain and snow drain away.
Paint the freshly cut ends of your deck boards with a matching outdoor deck stain.
