PS103 Lithium Silicate Densifier WB Penetrating Sealer (5 gal.) - Concrete Sealers USA
PS103 is a premium lithium silicate solution that is designed to penetrate into most unsealed cementitious surfaces to densify, harden, and increase the strength of the top layer of a substrate while retaining its breathability. It is easier and more efficient to apply than traditional sodium silicate densifiers and will not contribute to ASR (Alkali Silica Reaction). It is an ideal treatment for machine troweled, burnished, or polished concrete surfaces. Once the sealer chemically reacts with a surface, the PS103 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. PS103 has a clear 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 white pad.
