PREPARING THE MIX
-The mix can be prepared with a cement mixer, horizontal auger mixer or automatic pressure pump such as Turbosol. -Manual mixing using a shovel is not recommended, as this will prevent the proper homogenisation of the mix. -Mix thoroughly for at least 5-10 minutes. -The water must be measured carefully to obtain a mix with a “wet, almost plastic, earth” consistency which, in the compacting and tamping phase, must not create surface water. -Pour 1.6 litres of clean water per bag of Litocem Pronto and mix for at least 5 minutes. Do not adjust the indicated quantity of water so as not to compromise the final performance of the screed.

APPLICATIONS
-Once the obtained mix has a “wet earth” consistency, level bands must be created and used as a reference to ensure a flat, level surface. The level bands must be created at the same time as the screed. -The mix must be compacted so as to reduce cavities and voids, levelled using a metal ruler rested on the level bands and trowelled to obtain a smooth and closed surface without any rising water. -Trowelling can be performed with either a manual trowel or single disc machine. -When the pour is interrupted because the works are stopped, iron sections with diameter 5 mm and length approx. 30 cm must be inserted in the thickness of the fresh screed, spaced about 20-30 cm apart. -When casting the concrete, the bonding slurry made of 32.5 or 42.5 cement, water and Idrokol X20, must be applied with a brush to connect the two castings. -Also in this case, check that the slurry has not skinned over before pouring the new mix. -Alternatively, stop the pour near a threshold and create a construction joint for the entire thickness of the screed.
PREPARATION OF SUBSTRATES
-Along the entire perimeter and in correspondence with any elevations (columns, beams, etc.), Litoside compressible bands must be applied, acting as a perimeter joint. -Alternatively, it is possible to use similarly compressible materials such as expanded polystyrene, cork, etc. with a thickness of 5 mm. -In the case of floating or unbonded screeds, create a suitable vapour barrier (polyethylene or similar) against rising damp, overlapping the sheets by at least 20 cm and sealing them with adhesive tape, folding them up along the entire perimeter and in the presence of any elevations for the entire thickness of the screed. -Pipework and ducting laid under the screed should be avoided insofar as sudden changes in thickness may cause cracks and subsidence in the screed. -If it cannot be avoided, it is recommended to firmly secure the pipes or ducts and to insert a light hexagonal reinforcing mesh in the part of the screed affected by the crossing.
ADVANTAGES /FEATURES
-Product with very low volatile organic compound (VOC) emission rate. Complies with class EC1PLUS according to the EMICODE protocol and class A+ (Émission dans l’air intérieur - French Regulations) -Ready-to-use product that requires only the addition of water, thus preventing potential errors when batching the binder and selecting the aggregate -Ideal for the development of screeds in historical centres or inaccessible construction sites, where it is difficult to transport loose aggregates -Development of screeds with incorporated heating coils without the need for fluidifying additives -Quickly develops high mechanical strength, setting to light foot traffic in just 12 hours -No shrinkage during setting, which prevents cracking phenomena -Suitable for the development of floating or bonded screeds in indoor and outdoor areas, ideal for subsequent installation of ceramic and porcelain tiles after 24 hours, natural stones after 2 days, wood, PVC, linoleum, carpet flooring after 4 days
