Painting and coating in a marine environment of metal and craft elements constitutes, in our view, the ‘cutting edge’ of the industrial painting industry.
Environmental properties require the metal bodies to be partially or fully immersed in water and subjected to aggressive corrosive attack during and after application of the coating systems.
Furthermore, the exterior coating system applied to vessels, which sometimes does not exceed the thickness of a sheet of paper – is the one that is the only barrier between the metal body and the water environment in which it moves.
In light of the above, the implementation of a marine environment coating system is committed to meeting stringent application standards and constant testing throughout the process.
The process of renewing a vessel / construction coating system in a marine environment is characterized by several main steps:
1. Full removal of the old coating until a corrosion-free, corrosion-proof metal substrate is obtained according to SA-2.5 standard.
2. Implementation of Basic Layers (1-2) Adapted to the marine environment from the epoxy family of materials. Occasionally, it will use a type of coating that has proximity and cathodic protection (such as zinc paint).
3. Application of intermediate layers (3-5) of the epoxy or vanilla material families with solid, multi-thickness properties. 4. Application of top layers in accordance with the desired environment in the vessel will use a 3 layer anti-foaming coating system that has toxin release properties to prevent sea urchins (‘Bernix’) to the bottom of the vessel to prevent the vessel from slowing down when moving in the water. Near-sea elements and constructions will use a durable polyurethane coating system (UV2-3 layers) and with high permabile properties for chloride penetration and other salts.
5. The process of applying the color system is a long one and is a function of the waiting times (‘time windows’) for a full curing of a layer applied before the next layer is applied.
6. The dry film thickness of the systems ranges from 500 to 800 microns depending on specification.
