Wet coating

Wet coating is the most versatile and traditional surface treatment application method. Wet coating is a suitable method for most materials and items. There is a large number of different paints, paint suppliers and painting methods to choose from. With wet coating it is possible to achieve basically all atmospheric corrosivity classes required by the surface treatment instructions.

The most typical wet coat application methods are spraying, brush application and dipping.
In the subcontracting industry spraying combined partly with brush application is the most common method in use. Brush application is generally used to support other application methods and is often used on corners and cavities to ensure sufficient paint layers for corrosion protection.

Spray application can be divided in two different methods: air brush and high pressure spray paint. These methods are then subdivided in one-component and two-component spray systems.

The most used industrial wet coat application method is high pressure spray painting. The method is fast especially when used on larger parts. Smaller items and especially vehicle surfaces are treated with an air brush.

Depending on the atmospheric corrosivity, the painting system and paint the wet coating is performed in one to five layers. With several coat layers it is possible to achieve the desired results whether they are related in corrosion protection, mechanical durability or visuality.

Wet coating requires always an adequate pretreatment. Another industrial painting method is powder coating.
