Product overview
Ultra-flexible, micro-expanding, multi-purpose polymeric adaptive gel (2nd generation), Fluidotixo®-C4 / Fluidotixo® Dinamico, with low cement content for the installation of tiles, porcelain stoneware of all types and sizes, and natural stone, both indoors and outdoors. Designed to produce an extremely creamy, fluid and thixotropic mixture that maintains shape and thickness on floors and walls. Features 100% wettability, resistance to vertical slippage and an open time of over 50 minutes. Incorporates Active Transfer® technology for automatic filling of micro-voids and dynamic compensation for micro-movements during installation using levelling systems (wedges, tie rods and clips).

Key properties and functions

• Ultra-flexible, micro-expanding polymeric gel
• Fluidotixo® Dinamico / Fluidotixo®-C4 formulation (lightweight, highly flowable, thixotropic)
• Low cement content (<29%)
• Total wettability (100% wetting power)
• Resistant to vertical slippage
• Extended open time: over 50 minutes (E)
• Active Transfer® technology: automatic filling of micro-voids and dynamic compensation for micro-movements
• Suitable for use with tiling levelling systems (wedges, tie rods, clips)

Applications
Installation of ceramic tiles and porcelain stoneware of all types and sizes; installation of natural stone; indoor and outdoor use; application as overlay on existing surfaces; suitable over underfloor heating systems; terraces; swimming pools; façades; recommended for large-format tiles and deformable substrates where micro-movements or thermal stresses occur.

Performance and advantages

• Micro-expanding behaviour ensures active filling dynamics to produce a continuous, uninterrupted adhesive layer with improved mechanical and chemical adhesion and superior durability.
• Active transfer of adhesive forces: the adhesive interface becomes cohesive and resilient with no voids, preserving adhesion even on extra-large formats or deformable surfaces.
• Maximum contact area: uniform, continuous gel bed ideal for radiant heating systems and outdoor environments where temperature fluctuations demand a continuous ITZ layer for superior bond strength.
• Fluidotixo® Dynamic Mixture: highly flowable, thixotropic and lightweight mix that is easy to apply while maintaining thickness without sagging; allows corrections several minutes after application.
