How would you fibreglass a surfboard?

Answer 1

To make the board waterproof and to provide strength to the PU foam, four or six ounce fibreglass composites are laid on the blank which are then set in polyester resin. Before laying the fibreglass, decals(surfboard shaper logos) can be placed on the board.

Usually the bottom of the surfboard is covered with one layer of fibreglass and then covered with resin first, and when dry the same procedure can be done to the deck of the surfboard. Two layers of fibreglass can be placed put on the deck for a stronger surfboard.

If you want to cut down on weight, instead of placing two layers you can also just place an extra layer on the tail, nose and rails as these should have in little more protection.
