Layers of CSM

[two stroke mick]

I am now in a position to glass in my deck matrix. I indend to use 6 layers of 300gsm CSM. my question will six layers of 300 gsm be a strong as 4 layers of 450gsm?

TSM.
Aside. I indend to apply the six layers in one evening so it makes for one mass not a mass . I will be using resin at 1 % in cool/ cold conditions.

Gsm is gsm it's all about getting the layers to tie in with each other, ie. how well it is collsolidated. Make sure you are a good colsolidating roller and know how to use it so all the layers tie to each other with no air pockets / voids.

6 layers is a lot of glass to put down in one go, especially csm as you'll end up with a pool of resin if your not careful. I'd replace a couple of them with a layer of woven, it'll be a lot stronger, and you'll use less resin.
