The main characteristics

  • no slip or full spreading beneath a tile
  • foot traffic and grouting just after 12 hours
  • for floating, thin- and thick-coat application
  • for difficult substrates, inc. concrete, terrazzo, old tiles and OSB

Unique gel technology

The siliceous gel offers exceptional ability of water retention. It fills the pores formed at the stage of adhesive setting by the net of inorganic bindings. The accumulation of mixing water ensures full cement hydration, regardless the cladding type in use. Owing to the appropriate water management, which is necessary for the binding process completion, gel adhesive assures full adhesion to substrates of various absorptiveness level.


  • possibility of fixing cladding of any type, both absorbable and non-absorbable
  • possibility of optimum adaptation of the adhesive consistency to individual contractor’s preferences and actual needs resulting from particular use, by dosing water within a range much wider than in case of traditional adhesives,
  • safe cladding fixing on substrates exposed to direct sunshine, both during tiling and the adhesive setting (e.g. on balconies, terraces, etc.),
  • full adhesive spreading beneath the tiles, which improves adhesion and bond durability, particularly in case of outdoor use.


Wide range of adhesive thickness (2-15 mm) enables:

  • thin-coat cladding fixing on even substrates,
  • thin-coat cladding fixing on uneven substrates, preceded by substrate floating,
  • thick-coat cladding fixing on uneven substrates, with no need of substrate floating.

No cladding slip – enables fixing the cladding “from the top” with no need of support at the fixing stage.
Foot traffic and grouting just after 12 hours  - owing to accelerated adhesive setting and drying process.
