1708 on deck

[71kidcasper]

I'm using 1/2" marine plywood on my new deck and I'm planning on glassing both sides before I install it. Do you guys think 1708 on both sides is overkill? I'm just concerned with the weight. Trying to keep it light, but I want to make sure she is plenty strong and will outlast me.

Thats not overkill however you might want to use some matt as well on the top surface as the diagonal of the 1708 may bleed thru on your finished floor. What were you planning on for the walking surface of your floor? some people just epoxy the underside surface of the floor which is better then nothing. I prefer a light layer of glass.

Here's the thing about adding glass to Fir plywood unstead of just a couple of coat's of epoxy.

Fir plywood is what you would generaly buy as Marine plywood.
It's also lighter than Pine plywood.

If you don't add the glass the wood will still check and open up.

I have a long term experiment project that proves this well.
It doesn't take much glass. 4oz cloth will stop it.

Strick, When you say the walking surface on my floor are you refering to the glass or the nonskid? I'm planning on a layer of 1708,I'll take your advise on the print through, and a layer of 1 1/2 oz. matt. As for the nonskid I will most likely add it in the paint, although I've been thinking of putting some in the last coat of epoxy. I have done this on commercial boats in the past and it helps the nonskid from being worn away. I'm just not sure if the viscosity of the epoxy will consume most of the nonskid. I would like to have a fine texture to make comfortable on bare feet.

Anyone used rhino lining or any of the other liner material on their floor yet? I know it yellows but im going to be diving and deep dropping. That 5-10 # lead weight and the tanks banging around on the deck the little extra protection sounded pretty good.

There a quite a few folks that have sucessfully used Line-x.
