How to build a cardboard kayak for less than 40$ (Updated with template)

Step 10 Fold it all up, and laminate the seams

Fold it together, and laminate the seams. Again make sure they are as water tight as you can get them as a leak will spell certain doom. Make sure to do the inside as well as the outside, if you flip over, the inside needs to be just as waterproof as the outside.

so does the lament keep the seams together or some other adhesive or tape?

Yeah, i used the same stuff to laminate it as i did to seal up the seams. You could use like gorilla tape or some sort of heavy duty waterproof tape like that to seal the seams, but the stuff i used to laminate the rest of it works just fine on the seams too.
