Sika-1 is a liquid waterproofing admixture for cementitious materials like mortars and concrete, working by blocking capillaries and pores to create an effective water barrier. It's a normal-setting, chloride-free product that increases the impermeability of the applied system, making it suitable for applications such as waterproofing renders, masonry mortars, and screeds, particularly in basements and other structures requiring water containment.
