Sealing and protection of concrete floor is necessary for the proper installation. Concrete sealers are commonly used for concrete floors. They allow to protect the floor from excessive abrasion and stains. Sealers also facilitate floor maintenance and provide a long-lasting visual effect. Leading manufacturers of stone and concrete impregnants, such as Ultralit, ensure the appropriate chemical composition of their products. The basic ingredient of most Ultralit impregnations is lithium silicate and nanopolymers that improve the quality of the concrete surface.
