SPRAY-UP
Spray-up is an open mold method that can produce complex
parts more economically than hand lay-up. Chopped
fiberglass reinforcement and catalyzed resin, and in some
cases, filler materials, are deposited on the mold
surface from a combination chopper/spray gun. Rollers or
squeegees are used to manually remove entrapped air and
work the resin into the reinforcements. Woven fabric or
woven roving is often added in specific areas for greater
strength. General purpose, room temperature cure
polyesters are usually used to produce such parts as
truck camper shells and tub & shower stalls. As in
hand lay-up, gel coats are used to produce a high quality
colored part surface.
