Sanflor SD 12 Sodium-Based Concrete Hardener
Sanflor SD 12 is an alkaline liquid hardener, a penetrating eco-friendly water-based material for new and old concrete, artificial stone, and terrazzo floors. After application, it penetrates the concrete and reacts with free ions to form hard, insoluble solids. This seals capillary pores, enhances surface sealing, hardness, wear resistance, dustproofing, and impermeability, addressing inherent defects like abrasion, dusting, sanding, and permeability. It significantly improves functionality and extends the lifespan of concrete and artificial stone floors.
Applications
- New and old concrete or artificial stone surfaces.
- Cement-based wear-resistant hardened floors.
