HTC Superfloor™ HTC Superfloor in a fire station HTC Superfloor Silver Polishing concrete HTC Superfloor™ is a complete concept for polishing concrete. The polishing method mechanically refines the concrete surface by removing the top cement paste and exposing the underlying, stronger concrete. The existing concrete is grinded and polished according to a dependable and thoroughly tested method with HTC’s effective concrete polishing equipment and diamond tools. The result when polishing concrete is a floor with a completely even polished surface of a high quality, both functionally and esthetically. To achieve all technical benefits demanded for calling the surface an HTC Superfloor™, the grinding and concrete polishing must be performed according to the prescribed method. Several factors will affect the final appearance when polishing concrete: The stone quality and color. In Sweden the ballast material mainly consists of granite in different fraction sizes. The color of the cement (the cement can be pigmented). The concrete quality. Grinding depth: With different grit sizes and bonding matrix in the diamond segments you can somewhat control how deep you grind into the concrete surface. The grinding depth will affect how much of the stones that are exposed and also in turn the aesthetical appearance of the polished surface. The technical advantages when polishing concrete into an HTC Superfloor™ have been verified in several tests at the Swedish National Testing and Research Institute, SP (SP 99B4, 4806) (SS 13 72 41) (prEN 13892-3, Böhme) (EN 14617-3).
