Why is the marine environment so extreme?
Salt water, UV radiation, algae, biofouling and constant temperature fluctuations are an extreme combination for any surface. A boat that sits in water for half the year is exposed to forces that a car never experiences. Marine-specific solutions are essential.
Marine coating vs. car coating
Marine coating is formulated to withstand the saltwater environment and continuous UV exposure. It is generally more expensive and has higher chemical resistance than standard car coating. Never use standard car coating on a boat — it will not hold up in the marine environment.
What can be coated on a boat?
- Gelcoat (hull and deck): The primary surface, protected against UV fading and biofouling above the waterline
- Windows and perspex: Protects against salt deposits and water streaks
- Metal (pulpit, guardrails): Prevents corrosion
- Teak and timber: Specialist products for wood surfaces
Preventing biofouling
Coating alone does not prevent biofouling (barnacles, algae) below the waterline — that requires antifouling paint. But coating above the waterline reduces fouling and makes cleaning significantly easier, as dirt and salt deposits do not bond to the hydrophobic surface.
Service and maintenance
Marine coating typically requires a service visit every 12–24 months. Before hauling out for winter storage is a good time for inspection and refreshing. A professional marine detailer with specific experience in marine coating is the right person for the job.
