Revive Color Refresher is a penetrating, solvent-borne, siloxane-based colored water repellant. It was developed to improve the appearance of existing, unsealed exterior colored or uncolored concrete surfaces or concrete pavers in need of refurbishment or renovation. It adds color to the concrete without producing a paint-like appearance. It penetrates and reacts with the concrete so no film forms; its colors become part of the surface. L. M.
