Pre-fabrication of primers

Pre-fabrication primers are usually applied to steel plates and sections prior to fabrication e.g. welding/gas cutting. Also referred to as blast primers, shop primers, temporary primers, holding primers, etc., these primers are sometimes used on structural steelwork, immediately after blast cleaning, to maintain the reactive blast cleaned surface in a rust free condition until final painting can be undertaken.
