Litoliv Express QUICK-SETTING AND DRYING CEMENTITIOUS SELF-LEVELLER FOR LEVELLING OF SUBSTRATES WITH THICKNESS BETWEEN 3 AND 40 mm. SUITABLE FOR UNDERFLOOR HEATING. FOR INTERIORS. FIBRE-REINFORCED. PRODUCT WITH VERY LOW VOLATILE ORGANIC COMPOUND EMISSION RATE. Ready-mixed cementitious powder self-leveller made from special hydraulic binders, inert fillers of selected granulometry, organic additives and synthetic fibres. The product, once mixed with water, is characterised by an excellent self-levelling capacity and ease-of-application by hand or screw-pump plastering machine with variable thickness between 3 and 40 mm. Litoliv Express develops high mechanical flexural and compressive strength just 4 hours after application and thanks to its particularly fast drying time, allows the subsequent installation of ceramic and porcelain tiles, natural stones, textiles and resilient flooring in a very short time. 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) • Excellent adhesion on traditional cementitious substrates • Quick setting and drying • Development of screeds with incorporated heating coils without the need for fluidifying additives • Excellent self-levelling effect • Suitable for substrate levelling in electric and hot water underfloor heating • No shrinkage during setting, which prevents cracking phenomena • Fibre-reinforced product with improved resistance to expansion stresses in the presence of underfloor heating 20 kg bags - 1,200 kg standard pallet Levelling of substrates in indoor residential and public/commercial areas not subject to heavy traffic, in a variable thickness between 3 and 40 mm in a single coat. Typical applications include: • Levelling of cement screeds in indoor areas, also developed with Litocem or Litocem Pronto • Levelling on heating screeds • Levelling on sulphate/anhydrite-based screeds • Levelling on existing floors made with ceramics, natural stone and agglomerate coverings • Levelling of concrete slabs The substrates must be clean, solid, compact, crack-free, properly cured and without rising damp. Use of primer: • Excessively porous and absorbent or powdery substrates must be treated with the consolidating primer Primer C. The application of Primer C on absorbent surfaces improves the fluid application of the mix while also improving the level of adhesion • Smooth and compact substrates such as smoothed concrete, existing ceramic or agglomerate coverings, must be treated with the adhesion promoter primer Prepara Fondo EVO after being suitably degreased with specific detergents such as Litoscrub EVO • In the case of anhydrite screeds, check for the presence of a suitable vapour barrier in order to prevent rising damp. Use a carbide method hygrometer to check that the residual humidity is less than 0.5%. The surface must be sanded and treated with Primer C • Any cracks must be repaired with Multifondo EVO, sprinkling the fresh surface with sand or dried quartz with granulometry 0.4-1 mm In any case, the respective technical data sheets must be consulted for correct use of the indicated products.

Expansion joints Check that the perimeter, expansion, divider and structural elastic joints have been correctly designed and prepared. Divider joints are normally required for sections equal to 50 m2 or 25/30 m2 in the case of underfloor heating. In areas with surfaces less than 50 m2 expansion joints must nonetheless be inserted along each of the door thresholds. Pour the right quantity of water, depending on the application, into a clean container and slowly add the powder, stirring with an electric drill with mixing paddle until a consistent mix is obtained without lumps. Let the mix rest...
