What is Prime Coat? In road construction, a prime coat is an application of a low-viscosity binder to a non-bituminous (typically granular) base layer, such as a sub-grade or base course. This prime coat is designed to penetrate into the base layer and provide a sealed surface, to prevent the ingress of moisture and to provide a solid, adherent …
