Flo coat Gav? ;)

Hey

Today i did my boat with a layer of fibreglass resin colored in white. But it seems that it needs at least 2 or 3 layers . I thought you guys did it too with colored resin but it seems that people on this board(Gav) use gel coat?

What does flo coat contain? I know i will have to sand everything up again but now i want it to have good from the first time. I have a little bit of colored resin in gray for the splatters. Can i still use this if i'm going with the flo coat? How much kg would i need? It is for a fletcher 17Ft6 from the nose until transom? Which brush do i need?

Thx for your help

I know it"s a gelcoat but dont know or there are additives in it.

Is it true that you only need one layer?

Right ..........

Flocoat is..........60% gelcoat, 36% resin, 4% styrene wax solution(+catalyst of course).

Resin alone will be too brittle, gelcoat alone will be too thick and show brushmarks etc.

apply with a laminating brush, while main base coat is still wet( keep catalyst content to a minimum ie 1%) flick your second and third colours into it.....its that simple. i use a harris broom head or just use your hand wit a glove on.

One layer is the only way to go, applying a second will end up a dissaster !

i'll explain further if needed, right now i need my bed!

Good luck

Gav

Okey I called to a fibreglass shop today and they never heard about flo coat.
Than i told him the substances 60%gelcoat, 36% resin etc and they told me that it is called topcoat.

So is flocoat=topcoat? or not?

It sucks that i have to sand it all down again but that is the way that boats are. They ask so much time. But the advantage is that the underground? is +- white so i'll have to use less flocoat

it depends on what type of resin he's used, some resins like scott bader resin has a high wax content(low styrene emission) so would need sanding to key the surface ready for flocoat.

Yeh, I used the low styrene emission resin for my cabin but I've found a good wiping with thinners clears the wax from the surface. I've also just made sure I agitated the new flocoat thoroughly with the brush as I applied it and the wax re-dissolves into the styrene of the new resin.

Have you got more info about this Gav? How little is low? Can you see it on how much it shines? It is not that shiney.

I think i always do better by sanding it all down.

the less shiney the more waxey the surface will be, sand it down then flocoat it.
