Betonfix PRONTO

Shrinkage-compensating hydraulic mortar for fast drying screeds

Betonfix PRONTO is a hydraulic, ready-to-use mortar. It is used for fast drying (12h) screeds, shrinkagecompensating, with excellent mechanical strength. It allows a significant reduction in downtime activities in all structures with continuous operation (industry, public spaces, offices, hotels, etc.).

Applications

Betonfix PRONTO interior and/or exterior screeds suitable for ceramic tiles (12 hours later), natural stone (3 days later); parquet, resilient flooring (waiting time varies depending on the thickness of the screed and environmental condition). or localized to the complete revision of industrial floors with synthetic resin finish; screeds on domestic heating systems with radiant floor.

Certifications

Betonfix PRONTO è marcato CE come massetto cementizio, classe CT-C30-F6-FL secondo la EN 13813.

Application

It is a ready-to-use product, just needed to be mixed with potable water respecting qiantities mentioned in the aboveshown table. The amount of water is crucial for the rapid drying of the screed: an excessive addition of water results in significant delays. Betonfix PRONTO has the workability of a traditional concrete. Do not add water to mortar that has begun to set trying to reuse the dough: it will lose all its properties. Mixing should be done with normal construction equipment (mixer, planetary mixer or screw), delivered with pressure pump, and trowel applied. The surface of the substrate can be level with Betonfix RA after 24 hours of posing. In all applications, with the exception of screeds on radiant panels, the surface area should be clean and covered with a waterproof sheet (PVC, bituminous) against a possible rising damp on the substrate. Along the perimeter of the premises or at the internal elements such as pillars, must be placed a soft separation element (cardboard, polyethylene, polystyrene, etc..) with a thickness of 1 cm. The minimum thickness of the slab should be 4 cm: localized reductions in the thickness should be reinforced with wire mesh. Joint among different castings must be made by leaving a vertical cut and a steel mesh of union between the two castings. For floating screeds the thickness can be reduced up to 3 cm, suitably reinforcing the screed with a metal mesh. Possible joints for processing interruptions must be made leaving a vertical net cut and an electro-welded metal reinforcement joining the two castings, so as to have no height differences. Provide expansion joints in the case of screeds that exceed the 40 square meters of surface or 8 meters in length. In making screeds on radiant panel systems, the start of the thermal cycle begins after curing, at a supply temperature between 20 ° C and 25 ° C, which must be maintained for at least 3 days. Subsequently, the maximum design temperature must be set, which must be maintained for at least another 4 days, in accordance with the indications provided by EN 1264-4.
