High-Performance Solvent-Based Concrete Sealer & Curing Aid
Kingfisher Ultimate Topcoat is a high-solids, solvent-based acrylic sealer designed to protect, enhance, and extend the life of concrete, masonry, and natural stone surfaces. Formulated with premium-grade resins, it penetrates deeply to provide a durable satin finish that resists weathering, UV degradation, oil staining, and organic growth.
Suitable for both interior and exterior applications, Ultimate Topcoat functions as a curing membrane for new concrete, helping to control moisture loss and prevent shrinkage cracks. It also serves as a robust surface sealer and dustproofer for existing substrates, making it ideal for driveways, patios, industrial floors, and decorative concrete.
