Marine gelcoat spray guns are specialized tools designed for applying gelcoat coatings on marine surfaces. These systems ensure even, high-quality finishes with minimal overspray and waste. They are ideal for boat repairs, refinishing, and new construction in the marine industry.

Marine Gelcoat Spray Guns typically feature a nozzle size of 1.8–2.5 mm, with a pressure range of 40–60 psi. Coating systems may include polyester, vinyl ester, or epoxy resins with viscosities ranging from 300–1,500 cPs. Buoyancy properties depend on filler materials, often achieving densities of 0.9–1.2 g/cm³. Common materials include stainless steel or aluminum for spray guns and fiberglass-reinforced composites for coatings. Grade specifications vary by application, including ISO or ASTM standards for marine durability.

Marine Gelcoat Spray Guns and Coating Systems may comply with maritime standards such as ISO 12215 for small craft hull construction or ASTM D4541 for coating adhesion, but specific compliance depends on the manufacturer's specifications and certifications.
