Attention to the various stages of substrate preparation is key to ensuring the quality of the coating system applied to galvanized surfaces. Given the high frequency of complaints, each step can be considered important. Already at the design stage, it should be taken into account that galvanized structures will be further protected by paint systems. This will allow the selection of appropriate products and substrate preparation technology. Below I will present some solutions that significantly reduce the risk of coating defects. Most of the stipulations are in line with the assumptions of the specification for painting the so-called “paint”. offshore structures, which are those that operate offshore and serve oil and gas extraction processes. It is possible that some readers will find them exorbitant, but their application is reasonable, given the risk of possible complaints.
