Spray-up process combines chopper and spray guns to simultaneously place fiberglass-chopped roving and catalyzed resin onto a single mold surface, usually applied over a layer of gel coat that provides custom colors and desired cosmetic appearances. Hand tools like brushes, squeegees, and rollers are employed to remove air from the layered reinforcement. Part thickness is determined by the number of material layers placed on the mold. Precut fiberglass mat or roving may be added between spray layers if desired.
The spray up process allows for producing components with an unlimited choice of color.
Fiberdome has utilized this process to produce high quality parts for 40 years. Spray-up applications offer controlled rigidity, dimensional stability, and the process is very cost effective.
