Application
Surface contaminants, such as salt, may cause coating failure and increase maintenance costs for vessels, industry buildings and steel structures in general. Coating failure such as blistering and corrosion may be the result of a too high level of salt prior to painting. The Bresle Method described in the ISO 8502-6 is commonly used to measure the level of surface salts prior to coating. A so-called Bresle patch (a small self-adhesive plastic patch) with a washed latex membrane and a known surface area is used to dissolve the soluble salts. can be used to check for the presence of salts such as chlorides and sulphates on the substrate prior to the application of the coating.
