Polyester resin outside

Group: Forum Members Posts: 47, Visits: 2.1K	Hi all, I have a few kayaks to build over the coming weeks using glass and polyester resin. I have build before inside but due to moving house since last building, I will be forced to either rent somewhere, or build outside. The question is, does building using polyester resin outside affect the finished product as some people have told me that the styrene disappears too quickly meaning the cross linking doesn't happen properly? I have also heard that some larger boat manufacturers build outside when they can. Layup plan is Gelcoat -> 1x 450gsqm CSM (2 in high stress places for added strength) -> 300gsqm woven rovings all polyester resins. This is the standard layup for the kayaks and works well. Can anyone help clear this up for me? Panda. www.pandakayaks.co.uk Tags glass outside polyester styrene

What sort of boat is this? The reason I ask is that I've paddled boats that have been made of 6 layers of 450g for robustness.

Most of the boats end up between 7 and 12kg depending on the construction. I will post some pictures of the project once it gets started. I'm paddling a boat at the moment which is 1x 200g carbon, 1x 3mm foam core and 1x 200g kevlar. its a bit on the fragile side but weighs under 8kg and is stiff. Its only made for straight lines with no rocks ect so thats all its used for! Panda. www.pandakayaks.co.uk

I've also paddled squirt boats which are generally built like barges! I was never a fan of the tippy boats. I tried a stealth and thought better of it!
