Mapei Primer SN Part B is the reactive hardener for the two-component Mapei Primer SN epoxy system. When combined with Part A (16kg) in an 80:20 ratio, it creates a durable, versatile primer for use over concrete, terrazzo, and similar substrates before applying epoxy or cement-based flooring. The complete system can be tinted with Mapecolor Paste, allowing for custom-coloured base coats.
Must be used with Mapei Primer SN Part A.
