1/2.8mm Coated Grit – Bitumen Sealing Aggregate

Surface Sealant Aggregate – 1/2.8mm – Black Bitumen-Coated Finish

Designed for reliable road repair and surface preparation, our 1/2.8mm Coated Grit is coated in standard penetration bitumen, making it the ideal sealing aggregate for base courses awaiting a surface layer. Sometimes referred to as coated dust or moosey, this fine grit is essential for sealing surfaces when there's a delay of over a week between laying the base and wearing courses. Its key role is to prevent dirt, mud, or other contaminants from occupying surface voids, preserving the integrity of the road structure. Whether you're maintaining a driveway, car park, or road surface, this coated grit enhances appearance while boosting long-term durability.
