Cement self-leveling cast screed for floor construction of residential and administrative buildings made in thin layers of 4.5 - 7 cm with reduced shrinkage to eliminate cracks and create the effect of lifting corners. It is suitable for indoor areas where it offers faster strenght development and drying out against anhydrite, and can be used in places with permanent humidity. ZAPA SLIM is a cement-based screed with a self-leveling effect produced in accordance with ČSN EN 13813. It is produced in three strength classes: - CT-C20-F4 Compressive / tensile strength: 20/4 MPa - CT-C25-F5 Compressive / tensile strength: 25/5 MPa - CT-C30-F6 Compressive / tensile strength: 30/6 MPa It is produced at ZAPA premises and transported to the construction site by a concrete mixer in liquid consistency ready for immediate application. It is used as screed attached to the substrate (suitable adhesive bridge and surface treatment), screed on the separating layer, floating screed and as screed for underfloor heating (with a maximum medium temperature of 40 ° C).
