This British Standard specifies requirements for rapid drying priming paints containing a high proportion of zinc, supplied as two components, which react chemically when mixed together prior to use.
The paints specified are formulated for direct application to steel immediately after blast-cleaning to grade Sa 2½ of BS 7079 : Part A1. These paints are generally supplied as welding and prefabrication primers for thin film application, up to 25 µm dry film thickness or, for higher build films, typically up to 75 µm dry film thickness.
