What is the proper distance from the mold when spraying gel coat?

The recommended distance for spraying gel coat is typically between 12" to 18" from the mold surface. This range allows for a proper application that ensures an even and consistent coating, which is crucial for achieving the desired finish and appearance. Spraying too close can lead to excessive buildup and possible runs or sags in the gel coat, while spraying too far away may result in poor adhesion and a rough surface due to overspray and insufficient material reaching the mold. By maintaining the proper distance, you optimize both the quality of the finish and the effectiveness of the application process.
