It is a polyurethane resin-based, two-component, solvent-free, low-viscosity transparent primer. It penetrates the surfaces perfectly. Since it does not contain solvent, it does not smell and therefore can be used indoors. With its semi-hard feature, it becomes very resistant to abrasion and breakage after curing. In addition, the polyurethane-based primer material developed to be used in the preparation of the surface to be waterproofed is specially designed for damp or wet concrete surfaces. It cures in a short time and does not contain toxic substances. Solvent Free (zero VOC/Volatile Organic Compounds).
