Under the term corrosion we understand the oxidisation of metals by external, environmental influences. The progression of corrosion is dictated by the characteristics of the specific metal and corroding agent it is in contact with. Damp plays an important part in corrosion. For rust to appear there must be a chemical reaction between metal, oxygen and water.

There are other kinds of corrosion, caused by environmental factors such as air pollution, which, in today’s world, are unfortunately on the increase. Through these, either acids (such as sulphuric acid) or chlorine can appear on the surface of metals and damage them.

Corrosion protective coatings are an attempt to provide a barrier to the elements (such as air and water) as well as environmental influences such as industrial pollution, and thus protect and maintain metal.

Europe-wide, corrosion causes billions of euros worth of annual damage - damage which, with appropriate protection such as anti-corrosion coating, can be minimised.

To achieve optimal protection of a material, whether metal against corrosion or wood against the elements, requires a thorough knowledge of materials, to know which protection system may be used to protect which surface. In addition, a technician must have excellent knowledge of appropriate preparation and application techniques.
