I bought a house a while back that had a beautiful deck with 4
sections of 45 degrees and flower pot holders etc. The problem was
the builder paid no attention to cupping of the decking. Soon most of
the boards had curled on the edges and whenever it rained it took
hours for it to dry or I had to sweep it. Also splinters developed on
the edges and decking screws pulled lose. A word to the wise....
