Flooring screed adhesive mortar ACTIVEGEL® S1

for tilefor wallpolymer

Short description
Super-flexible, micro-expanding, multi-purpose polymeric adaptive gel Fluidotixo®-C4 with low cement content, total wettability and active transfer of adhesive forces for the installation of tiles, porcelain stoneware and natural stone of all types and sizes, for internal and external use. Incorporates Active Transfer® technology for automatic filling of micro-voids and dynamic compensation of micro-movements during installation with levelling systems (wedges, tie rods and clips). Coverage: 2.5–5 kg/m². International patent application filed No. 102025000025369.

Product description
Super-flexible, multi-purpose second-generation polymer-modified gel formulated with Fluidotixo® Dinamico (Fluidotixo®-C4) and low cement content (<29%) for fixing tiles, porcelain stoneware and natural stone on floors and walls. Designed to produce an extremely creamy, fluid and thixotropic mortar that retains shape and thickness on vertical and horizontal substrates. Provides 100% wettability, vertical slip resistance and an open time exceeding 50 minutes. ActiveGel® S1's Active Transfer® technology enables controlled micro-expansion to fill micro-voids that can form when using levelling systems.
Delivers high-performance, super-flexible dynamic adhesion that compensates for micro-movements and voids, improving installation security on large-format tiles and deformable substrates. Suitable for overlays on existing surfaces, underfloor heating systems, terraces, swimming pools and façades while maintaining adhesive transfer and flexibility.
Classified C2TE S1 – EN 12004.

Advantages

• Micro-expanding: Active filling action that creates a continuous, uninterrupted interface with improved mechanical and chemical adhesion and enhanced durability.
• Active transfer of adhesive forces: Ensures a cohesive, void-free adhesive interface with no loss of adhesion, stabilizing installations on extra-large formats and deformable substrates.
• Maximum contact area: Uniform, continuous gel bed ensures full contact in the interfacial transition zone (ITZ), ideal for radiant systems and outdoor applications with thermal stress.
• Fluidotixo® Dynamic Mixture: Highly free-flowing, thixotropic and lightweight consistency that is easy to apply, resists sagging, allows adjustments minutes after application and provides extended open time (>50 min).
