Two component, low viscosity, moisture tolerant epoxy based primer. Developed as a penetrating concrete preaparation primer for polyurea, polyurethane and epoxy coating applications. It penetrates and strengthens the surface of the concrete, reduces pin-hole formations and provides a chemically reactive surface to accept coatings. Prevents moisture and water vapour penetration. Adhesion is increased by up to three times that of unprimed concrete. It is designed for use in both interior and exterior priming situations. After curing it has high tensile and mechanical properties
