What Is Marine Spray Painting?

Marine spray painting refers to applying protective coatings to equipment, structures, and vessels in sea-faring and coastal conditions. It requires using specialised spray paints able to withstand harsh marine environments.

Unlike regular spray paint, marine coatings are designed to handle long-term exposure to salt, humidity, UV radiation, and varying weather conditions. They form a durable, corrosion-resistant barrier able to endure in the harshest of sea climates.

The key is using paints specifically formulated for marine use. These contain resins, pigments and solvents resistant to seawater, UV damage and corrosion. Epoxy and polyurethane paints are popular options, with a hard, glossy finish that stands up well to abrasion.

Marine Spray Paint Application

Application also differs from commercial spray painting. Marine coatings require meticulous surface preparation to remove contaminants and provide “tooth” for the paint to grip onto. They are applied in multiple thin coats, with adequate drying time between layers. Strict environmental controls are needed to avoid issues like solvent entrapment.

How Often Does Marine Paint Need To Be Reapplied?

Proper maintenance is essential. Inspecting marine paint regularly and promptly repairing any damage helps prevent corrosion. Periodic recoating sustains protection, with most marine paints requiring a new topcoat every 3-5 years.
With the right products, careful application and ongoing maintenance, marine spray painting creates a durable shield between equipment and the sea. For anything operating in coastal areas or saltwater, it’s the best way to prevent premature deterioration and keep assets in working condition.

Why Marine Paints Are Different From Standard Paints

Marine paints are specially formulated to withstand harsh ocean conditions. Unlike regular spray paint, they’re designed to grip onto damp surfaces and resist salt, weather, chemicals, and abrasion.

Resistance to Corrosion

The sea is highly corrosive, so marine paints contain anti-corrosive pigments and resins to prevent rust and deterioration. Epoxy and polyurethane paints are popular options as they form a durable, chemical-resistant coating.

Flexibility and Adhesion

Marine paint needs to flex with the movement of the hull and adhere strongly even when wet. Polyurethane paint is elastic, sticking to surfaces even under stress. Special adhesion promoters help the paint grip onto damp, salty substrates.

UV Protection

Intense sunlight and UV radiation can cause paint to fade, chalk, and break down. Marine paint contains UV absorbers and stabilisers to prevent damage from sun exposure while maintaining colour.

Mould and Mildew Resistance

The damp, humid ocean environment promotes the growth of mould, mildew, algae and other microbes. Marine paint contains biocides and fungicides to prevent unwanted biological growth which could damage the coating.

Is Marine Paint Only for Boats?

Marine paint isn’t only for boats and yachts. Many industrial and commercial applications also benefit from coatings designed to withstand harsh, humid, and corrosive sea environments.

Infrastructure

Bridges, piers, offshore oil rigs, and other structures in coastal areas or over saltwater are prone to rust and deterioration. Marine-grade paints, primers, and sealants help protect rebar and steel from the damaging effects of salt spray and oxidation. These coatings are also resistant to algae, mould, and mildew that thrive in humid, sea-level conditions.

Equipment

Cranes, pumps, pipes, and machinery operating in dockyards, shipyards, and other seaside facilities require protection from corrosion and rust. High-performance marine paint shields critical equipment from the elements so it continues functioning safely for many years. These industrial coatings are also impact-resistant and durable enough to withstand minor dings and scratches.
