Deck edging

I'm not sure there's a way to support a new deck board above the coping along the straight sides of the pool. I was thinking that you could place a 2 x 4 on edge over each row of screws/nails in the old deck and place a new deck on top of this that would overhang the coping. But you would need to use a 2 x 8 on edge that was notched out so that it extended over the coping and was still thick enough to support the new deck. If you used a 2 x 6, the notch would only leave a 2 1/2 inch thick portion to support the deck over the coping - this is not enough. You are looking at raising the existing deck by about 9 inches and the new deck would be higher than the coping by 5 1/2 inches. I'm not sure that would be satisfactory.

If this is still something you want to try, I'd suggest using pressure treated for the 2 x 8's and "Trex" or similar plastic/pvc/recycled decking. You can then make a "face" that attaches to the edge of the new 2 x 8/deck to cover the edge. Your fence will appear quite a bit lower from the new deck as well. I'll still do sketches if you want. It appears to be a lot of work (and pricey). How about just painting the coping?
