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.
