i have done alot of reading on this site and was wondering.... poeple on here said when putting a new deck on your boat you have to first fiber glass the edges. that part i understand now here is the question. they say next to put 2 thin layers on the deck to cover the wood. does it matter if it is 2 thin layers or one thick layer. im thinking thin is 1.5 ounce and thick would be 4 ounce . does 2 thin layers make a stronger deck than one thick layer.
 

oops!

thick would be a 24oz.

the glass it there to waterproof the deck and provide srtuctural stability.

a csm (chopped strand matt) and a final layer of woven roving would be strong....

you could use these in lighter qualities. below 7 oz

I'm going to be doing my deck with one layer of 8 oz, two layers if I get ambitious. I just happen to have a lot of 8 oz fabric.

I used one layer of 1.5 mat, then one layer of 8 oz. cloth. I figured this should be strong enough.

The mat is there for a good base for the cloth.​

Yeah, I should mention that I use epoxy, so no mat needed.

If you use poly resin, mat is a really good idea. Epoxy, one layer is fine.

Regardless you're looking to build up enough of a surface of glass and resin to protect the deck from abrasion, waterproof it, and bond it to the rest of the boat if you haven't done that otherwise.

Any way you do that is fine as long as it achieves all that.
