Semi-fast drying hydraulic binder based on highly resistant special cements and synthetic additives for creating substrates on which tiles can be fixed. Used for making bonded and floating screeds (also of the heated type) from 2 to 10 cm thick. To be mixed with gravel (0 to 8 mm grain size). Free from shrinkage. The screed obtained is suitable for laying ceramic floor tiles after just 24 hours and for laying parquet after 4-7 days.

For indoor and outdoor use.
