I built a 10'x22'deck out of PT 4x4's filled with fine gravel for our site. last year we just placed a couple of odd pieces of carpeting on it. Now we just purchased a large enough indoor/outdoor carpet to cover the entire deck. I plan on going over the 4 x's to secure it but am not sure what to use for fasteners. Staples will rust and possible tear. Are there suitable fasteners for this application?
Any suggestions?
