A single coat inorganic zinc silicate can provide long-term protection to steelwork in many atmospheric environments. As a single coat system applied relatively thinly, it is also very economical and can allow rapid throughput of coating work. However there are some disadvantages and costs to be incurred when using this material. These have led to a number of myths and misunderstanding regarding inorganic zinc silicate coatings which have led to its misuse, failures or neglect. This paper discusses some of these fallacies and points out some of the issues involved in selection, application and maintenance of these coatings.
