2 S te li ra lt U TH EUROPEA E WI N NC EN 12004 S EN 12004 IN COM PLI A OU ER SA DHESIVE FOR C One-component, highperformance, highly-deformable, lightweight cementitious adhesive with a long open time and extremely high yield, easily trowellable with high backbuttering properties, for ceramic tiles and stone material, ideal for thin porcelain tiles AM IC T ILES C2E S2 RDS NDA TA CLASSIFICATION ACCORDING TO EN 12004 Ultralite S2 is a C2E S2-class cementitious (C), improved (2), long open time (E), highly deformable (S2) adhesive. Ultralite S2 has been awarded EC certification, as indicated in ITT certificate n° 25110055/AG (TUM) and n° 25110056/AG (TUM) issued by the Technische Universität München laboratory (Germany). WHERE TO USE • Bonding all types and sizes of ceramic tiles (doublefired, single-fired, porcelain, klinker, terracotta, etc.) on internal and external substrates. • Bonding stone on internal and external surfaces (only stone which is stable and not sensit

ive to humidity). • Bonding all types and sizes of thin porcelain tiles on floors and walls, including external façades. Specifically developed for large-sized tiles to be laid on large surface areas without double buttering. Because of its high buttering capacity on the backs of tiles, it is particularly suitable for laying any type of thin porcelain tile (using the double buttering technique), including on thermal insulation systems such as Mapetherm Tile System. May be applied in layers up to 10 mm thick. Some application examples • Bonding ceramic tiles (double-fired, single-fired, porcelain gres, klinker, etc.), stone (if stable in damp environments) and thin porcelain tiles on conventional substrates, such as: ITI NT CEME – on “damp earth” consistency and self-levelling cementitious screeds and anhydrite (after applying a suitable primer); – heating screeds; – cementitious render or lime-mortar render; – gypsum render (after applying a suitable primer); – pla

sterboard, pre-fabricated panels, cement-fibre panels; – waterproofing membranes in Mapelastic, Mapelastic Smart, Mapelastic AquaDefense, Monolastic, Monolastic Ultra and Mapegum WPS. • Laying ceramic and stone on old floors (in ceramic, marble, etc.). • Laying on marine plywood, wooden agglomerates and old, stable wooden floors. • Laying ceramic and stone on balconies, terraces and paving slabs exposed to direct sunlight and thermal gradients. • Laying on prefabricated concrete walls and concrete substrates. • Laying thin porcelain tiles on Mapetherm Tile System thermal insulation systems (refer to specific Technical Notebook). TECHNICAL CHARACTERISTICS Ultralite S2 is a grey powder made from cement, selected graded sand, a high amount of synthetic resin and micro-spheres of recycled silica material which helps to make the mix lighter, according to a special formula developed in MAPEI’s research laboratories, to offer a valid contribution towards the development of susta

inable buildings. The special technology used to manufacture S2 te ali ltr U Ultralite S2 gives it a lower density, which offers two main advantages: 1) sacks of Ultralite S2 have the same volume but weigh less (15 kg) than sacks of conventional cementitious adhesive (25 kg). This makes for easier handling and savings in transport costs; 2) higher yield: yield is approximately 80% higher than MAPEI S2-class, two-component cementitious adhesives. Ultralite S2 mix has a low viscosity, which makes it easier and quicker to apply. The product’s excellent buttering capacity on the backs of tiles means that the doublebuttering technique may be avoided when laying large tiles in internal environments. Its excellent back-face buttering capacity also makes this adhesive particularly suitable for laying thin porcelain tiles. The application of Ultralite S2 using the double-buttering technique on flat substrates ensures that there are absolutely no gaps in the adhesive on the backs of the til
