One-component, high-performance, highly deformable, lightweight, cementitious adhesive with extended open time, Low Dust technology and extremely high yield. Easy to apply by trowel with excellent back-buttering capacities, for ceramic, mosaic and stone tiles. Particularly suitable for laying large format-tiles.
WHERE TO USE
·Bonding all types and sizes of ceramic tiles (double-fired, single-fired, porcelain, clinker, terracotta, etc.).
·Bonding stone tiles on interior and exterior surfaces (as long as the stone material is dimensionally stable and not sensitive to moisture and staining).
·Bonding large-format porcelain tiles, also thin tiles, on floors and walls, including exterior façades.
·Bonding all types of mosaic on interior and exterior surfaces, also in swimming pools.
·Thanks to its high back-buttering capacities, it is particularly suitable for installation of Mapetherm Tile System XL on façades and external thermal insulation systems.
TECHNICAL CHARACTERISTICS
Ultralite S2 Flex is a grey or white powder made of cement,selected graded sand and a high amount of synthetic resin, admixed with lightweight, natural aggregates that make the mix lighter, according to a special formula developed in MAPEI Research & Development labs.
Ultralite S2 Flex is a product with very low emission of volatile organic compounds (VOC), which safeguards the health and safety of installers and final users. It is certified as EC1 Plus.
Ultralite S2 Flex helps earn important LEED credits.
Ultralite S2 Flex offers the following advantages:
·The Low Dust technology which characterises this adhesive considerably reduces the amount of dust given off when mixing the product compared to standard MAPEI cementitious adhesives, making installers’ work easier and safer.
·The special formulation used to manufacture Ultralite S2 Flex gives it a low density, a characteristic which offers two main advantages:
1.bags of Ultralite S2 Flex have the same volume but weigh less (15 kg) than bags of conventional cementitious adhesive (25 kg). This means less effort for the workers, as the bags are easier to handle on the construction site and storage warehouses. Furthermore, lightweight leads to clear benefits in terms of reduced transport costs: indeed, one pallet of Ultralite S2 Flex weights 750 kg while one pallet of conventional adhesive weights 1250 kg;
2.higher yield: each 15 kg-bag of Ultralite S2 Flex has approximately the same yield (in terms of square metres of tiles installed with the same type of trowel, installation technique and substrate) as that of 25 kg bags of conventional MAPEI cementitious adhesives.
·Ultralite S2 Flex has a low viscosity, which makes application quicker and easier.
·Its high back-buttering capacities make this adhesive particularly suitable for laying thin porcelain tiles. The application of Ultralite S2 Flex using the back-buttering technique on flat substrates ensures that there are absolutely no voids in the adhesive on the back of the tiles, thus avoiding the risk of fracture when in service.
When mixed with water, Ultralite S2 Flex forms a mortar with the following characteristics:
·excellent capacity of absorbing deformation in the substrate and tiles;
·excellent back-buttering properties;
·perfect bond to all materials normally used in the building industry;
·particularly extended adjustment and open time to make installation easier.
The deformability class of Ultralite S2 Flex is S2, according to the standard EN 12004, and, unlike other adhesive with similar characteristics, it does not need to be mixed with latex, thus making its application easier and quicker.
