Marine paints, varnishes and preparations

A two-component polyester spray filler (putty) for quick and uniform leveling of large surfaces. Sea-Line Polyester Spray Filler is applied with a spray gun to fill scratches, pinholes, and minor unevenness. It cures fast (around 3 hours) and sands easily to a smooth surface – the perfect base for primer and paint.

• Sprayable liquid formula – provides even coverage over large areas with no hand-sanding marks
• High build capability – forms a thick layer that hides small defects and waves in the surface
• Fast curing (~3 hours at 20°C) – speeds up the repair process and saves time
• Easy to sand to a fine smoothness – sands uniformly with minimal effort, creating an ideal paint-ready surface
• Available in kits: 1kg (with hardener, for small repairs) and 10kg (for large projects or entire hulls) – choose the size to fit your needs

Thinner for two-component polyurethane paints and varnishes when applied by spray gun. Sea-Line Spray Thinner 2K ensures ideal viscosity for fine atomization, fast evaporation, and a smooth finish with no runs or haze. 

• Specially formulated for spraying 2K polyurethanes – provides correct viscosity for a consistent spray pattern
• Improves flow and leveling – the final coat lays down smooth and even with a high gloss finish
• Prevents paint sagging on verticals – thixotropic effect controls film build without drips or runs
