The Prime One Coat Sealer is built for exposed aggregate concrete driveways, paving, and outdoor entertaining areas. Its solvent-based, xylene formulation penetrates deep into the surface, binding and sealing to protect against dirt, oil, and contaminants while resisting weathering and UV damage.
Unlike multi-coat systems, this sealer is engineered to work in just one coat — saving time and money without compromising durability. With its penetrating action, it enhances the natural colour of decorative concrete, delivering a fresh, long-lasting finish that stands up to Australian conditions.
