A superior water-based primer for use on mild steel surfaces with exceptional adhesion to properly decreased galvanised sheeting. It also contains anti-corrosive pigments to prevent rust. It can be top-coated with water-based emulsion paints and decorative enamel paints once cured properly (not to be top-coated with epoxy or automotive enamels). Highly recommended for lightly “keyed” PVC and plastic piping. Quick drying with excellent coverage.
