Is it necessary to use plastic film when laying up or is it to cut down on finishing? I have a repair to do on the inside where there is a wear spot and am wondering if I need to seal it with plastic for it to hold and cure properly. Thanks!
Hi- The plastic wrap is only to make the outside smooth as glass. You can't really put plastic on the inside. Can't stretch it tight-becomes a trampoline. Just lay the patch inside, making sure to wet out the patch completely. Soak up excess resin around patch edges with a clean rag and let cure. That's it. Paddle.
@@ElyresortBlogspot It’s a Scott 16 foot prospector canoe. It may have had gel coat at one point, I can’t tell but something tells me no. The guy painted over it with regular paint so I don’t know if it’s gel coat underneath.
There is no particular requirement. Kevlar is stronger than glass. Need less to achieve good strength. Glass on a Souris River is there as a superior scuff guard compared to other brands which only use Kevlar only. Can't sand Kevlar but you can sand glass. Regarding glass over the patch, it's not that big a deal especially when the resin is ramped up to the patch so the patch does not have abrupt edges.
So how long to leave the plastic wrap on??? Answer... take it off right away!! He doesn't tell you and I am a novice so I left it on a couple hours and when you peel up the wrap the patches come right with it! I scoured the internet searching for the answer too. I will not be so quick to accept internet advice...
Epoxy resins for laminating always harden with a tacky surface to aid the application of the next layer. If you're not applying a next layer. you prevent that tackiness by excluding the air. When the film comes off it will be a hard shiny surface.
@@pbassred , Impressive the epoxy is designed to do that. I covered my teardrop and it was tacky. Figured I had mixed the wrong ratio. So tried a thin layer of hardener and it worked.
good video. What would you use to fill screw holes on kevlar deck

+Joe B thanks for clearing that up for me. Happy paddling!
I have to do a patch repair but the Kevlar boat I bought was painted. Do I have to sand off the paint?
Is it paint or gel coat? Also, is it a boat or a canoe?

Did you sand this entire boat to apply this patch?
Shouldn't the final layer be fiberglass like the inside patch? I thought the outside layer was glass.

+Joe B - Thanks. Good to know.
