Spray-up Process

Last modified: 12/20/2007


Spray-up is an open mold process. Mold release and gel coat are applied to the mold. Catalyzed resin along with fiber glass roving is fed through a gun at the same time. The roving is chopped into 12 to 24mm lengths and deposited on the mold along with the resin. A roller is used to remove air and insure complete wet out and wet through.
