If you check out this thread: http://www.microskiff.com/cgi-bin/yabb2/YaBB.pl?num=1241373131 You'll see I'm going to be in need of some supplies here soon. How many layers of cloth should I use on each side of the deck? I'm going to use one sheet of 1/4" luan and will not have any areas that are more than 6" square that are unsupported. I will also fill the spaces with foam. My calculations show that I have about 75 square feet of area to cover on the deck areas. I'm using the formula at http://www.fibreglass.com/HOWTO/k-fun-fibre.htm My calcs show that I need about 50oz. of resin per layer if I use 6oz cloth. Will 2 layers of 6oz cloth on the topside and one on the bottom be enough?
using 1/4 inch luan, I'd use 2 layers of 6 oz tooling cloth on each side. example of resin consumption with 6 oz cloth: http://picasaweb.google.com/bdefalco/FinishingTheGrassSlipper#5263755352881828818
Think I should go thicker with the wood or will that be enough? I'm still in the planning stage so it's easier to change now than later. I just figured it would be easier to work with.
Try it, I was surprised by how rigid the luan became with a single skin on each side. Lay it up before installing. Check for flex in place before final installation. 6" square under deck reinforcing pattern will make this very rigid. Don't forget to prime and seal the luan with epoxy before glassing.
