Whether you are coating an oil tank or a pipeline; a ballast tank or a flat roof; a filing cabinet or an appliance - there are many parameters that must be monitored or controlled to ensure the coating performs over the lifetime of the product. One of these parameters is how well the coating has “covered” the surface, and if there are any “flaws” in the coating which could lead to a premature coating failure or corrosion.
