Ultralite S1 is a C2TES1-class cementitious (C), improved (2), slip-resistant (T), extended open time (E), deformable (S1) adhesive.

WHERE TO USE

• Bonding all types and sizes of ceramic tiles (double-fired, single-fired, porcelain, klinker, terracotta, etc.) on uneven internal and external substrates, without having to even out the surface before fixing.

• Bonding all types of mosaic on internal and external surfaces even in swimming-pools.

• Bonding natural stone on internal and external surfaces (for stone which is stable and not sensitive to humidity).

• Bonding thin porcelain tiles on floors and walls, including external façades.


Some application examples

• Bonding ceramic tiles (double-fired, single-fired, porcelain, klinker, ceramic and glass mosaic, etc.), stone (if stable in damp environments) and thin porcelain tiles on conventional substrates, such as: – cementitious and anhydrite screeds (after preparation and applying a suitable primer); – heated screeds; – cementitious render or lime-mortar render; – gypsum-based plaster (after applying a suitable primer); – plasterboard, pre-fabricated panels, cement-fibre panels; – waterproofing membranes Mapelastic, Mapelastic Smart, Mapelastic Turbo, Mapelastic AquaDefense and Mapegum WPS.

• Laying ceramic and natural stone on old floors (in ceramic, marble, etc.).

• Laying on marine plywood, wooden agglomerates and old, stable wooden floors.

• Laying ceramic and natural stone on balconies and terraces and paving slabs exposed to direct sunlight and thermal gradients.

• Laying on prefabricated concrete walls and concrete substrat

RECOMMENDATIONS

Do not use Ultralite S1 in the following cases:

• on metal, rubber, PVC and linoleum; • for slabs of marble and natural stone which are subject to efflorescence or staining;

• for natural agglomerate stone with high coefficients of moisture expansion.

• when the floored surface must be put quickly back into service.

Do not use Ultralite S1 for installing thin porcelain tiles with reinforcement mesh larger than 5000 cm² on internal surfaces and heated screeds. Use an “S2” deformability class adhesive for this type of application such as Kerabond Plus mixed with Isolastic, or Keraquick S1 + Latex Plus. When installing thin porcelain tiles on external facades and for further information on how to choose the correct adhesive, refer to the MAPEI technical manual “Selection Chart of Adhesives for Ceramic Tiles and Stone Material” available for download from our website www.mapei.com. au or alternatively contact the MAPEI Technical Services Department on Freecall 1800 652666 or email [email protected] or contact MAPEI Technical Services Department. Do not add water to the mix once it starts to set
