Paving coating is a surface treatment applied to paved surfaces such as asphalt, concrete, brick, and natural stone to protect the material, enhance appearance, and extend service life. Coatings can form a protective film on the surface or a penetrating layer within pores, reducing water ingress, chemical attack, and UV damage. They may also improve slip resistance and color uniformity.

Types of paving coatings vary by chemistry and intended performance. Penetrating sealers (for example silane or siloxane-based products) infiltrate the surface to reduce porosity without changing the appearance. Film-forming sealers and coatings (such as acrylic, polyurethane, or epoxy systems) create a visible protective layer on top of the substrate. Elastomeric coatings are used to bridge small surface cracks and accommodate movement in some pavement systems. Selection depends on substrate, climate, traffic, and desired aesthetics.

Applications typically begin with thorough cleaning, repair of cracks, and ensuring the surface is dry. Coatings are applied by spray, roller, or squeegee to achieve even coverage. Cure times vary by product and conditions and may restrict foot and vehicle traffic during the curing period. Maintenance often involves periodic cleaning and reapplication every few years, depending on exposure, wear, and coating type.

Considerations include environmental impact, such as VOC content, and safety during handling. Compatibility with the pavement material and proper surface preparation are important to prevent adhesion problems, peeling, or trapping moisture.
