Tophard LS is a special lithium based silicate solution that penetrates deep inside the concrete capillaries chemically reacting with the free lime forming a permanent insoluble bond with the concrete, which increase density, hardness and strength of the top layer of a substrate while retaining its breathability. It is an ideal treatment for machine troweled, burnished, or polished concrete surfaces. Once the sealer chemically reacts with the surface, the Tophard LS improves the abrasion resistance and durability of a surface, provides long term protection against wear and traffic, reduces dusting not caused by actual surface defects, and lowers the overall maintenance of a surface. It can also serve as a concrete polishing aid by producing better initial surface hardness that reduces polishing time and yields a smoother and denser burnished or polished surface. Sealer is environmentally friendly, VOC compliant, non-flammable, and has odorless formula for safe indoor use. Tophard LS has a clear to turbid appearance. Upon proper application, the substrate will have little, or no, noticeable change in appearance when dry. However, a polished appearance can normally be imparted to burnished or polished surfaces by applying with scrubber or polisher and then buffing with a resin pad.
