LIQUI-HARD ULTRA concrete densifier and chemical hardener is a waterborne, lithium-silicate-based, ready-to-use, colorless liquid, which hardens and dustproofs concrete at a molecular level. After proper application, the finished surface offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the surface when compared to untreated concrete. As LIQUI-HARD ULTRA is applied and penetrates into the concrete surface, a chemical reaction takes place, producing a byproduct that fills in the pores of the concrete. LIQUI-HARD ULTRA solidifies the concrete, eliminating dusting and pitting.LIQUI-HARD ULTRA is chemically engineered to provide timely, quick, sustainable performance. The product is applied and then left on the surface for 5 - 10 minutes. In this short period of time, the colorless liquid quickly penetrates into the surface. After application, the resulting surface features enhanced protection and sheen, coupled with superior abrasion resistance. This environmentally safe, water-based product features a zero VOC content and provides an attractive option in green building applications.
