Hey, I am in the process of making my first board. Its a stringer less short board shaped from polystyrene foam so I plan on doing a double layers of 6oz cloth epoxy top and bottom.
Question is: Do I glass one layer then let it dry 24h then do the nest layer on that? If so, do i sand the first layer? Or do I lay both sheets on top of each other and glass them? (this seems like it would be hard to get the epoxy to soak in the fiberglass…?
Both layers at once although you can do one at a time. Epoxy finds it’s own way down and doesn’t need to be pushed between the weaves like poly. Just spread it, wet out and tuck the laps and draw out the excess. Squeegee is important too. Get one of the Bondo spreaders. Keep a brush handy if the squeegee gives you trouble. Wet out with the brush, draw out the excess with the squeegee.
