Hello, i’m new to composites and i am making a kiteboard. I bought some pvc foam from easycomposites and have glued two sheets together a 20mm sheet and a 3mm sheet to give my required thickness. I used gorilla glue and applied it all over in a zig zag pattern. The bond is good apart from the edges where there are some bits that are lifting as they didnt have glue. I plan to vacuum laminate with carbon cloth and then apply a epoxy coat to finish. 

I am hoping that because i’ve got good bonding overall and because its the same material sandwiched together and i’m laminating around the edges it wont delaminate later. What do you guys think? should i do something to remedy or just crack on?
thanks!

Thanks guys. Unfortunately i have gone a bit further today and laminated the bottom of the board Before reading your replies (thats the side that doesnt have the 3mm foam). I’ll see tomorrow how it looks and then make a decision. 
i’m not clear how to go about removing 3mm with a router when its all over? How would you do that? Maybe i could use an electronic plane? Thanks for the replies
