All steel structures need periodic maintenance. During maintenance of the corrosion protection of such structures dry abrasive blasting has traditionally been standard practice. Over the years it has become more and more common to use water jetting for this purpose. Water jetting leaves a clean surface, free of old coating, loose particles, salt and contamination. Although water jetting produces no additional surface profile, the profile of the substrate during the new build stage is renewed. One downside of water jetting is the formation of flash rust. The degree of flash rust increases with various parameters such as temperature, relative humidity and soluble salt contamination. Furthermore, after water jetting the surface may be moist or damp, and to ensure a fast return to service the maintenance coating needs to be water tolerant. This paper presents a newly developed epoxy primer tailormade for moist and flash rusted surfaces.
