A multifunctional gel-based adhesive with enhanced strength and high flexibility, designed for bonding porcelain stoneware, ceramics, and natural stone. This product is classified as a thin-bed, frost-resistant, and waterproof cementitious adhesive with improved strength and high flexibility (type C2TES1). It is formulated with high-quality mineral binders, polymers, and silica gel, which allows the consistency of the mortar to be adapted to even the most demanding conditions. During mixing, the consistency can be adjusted as needed—ranging from a semi-liquid state, which facilitates tiling work on floors, to a standard consistency, which is ideal for use on vertical surfaces. Furthermore, the silica gel has the capacity to retain water and release it during the setting process, ensuring proper hydration of the cement throughout the entire curing phase and significantly enhancing the adhesive's mechanical properties. The use of carefully selected fillers and a thickening system makes the product exceptionally easy to work with, ensuring it is lightweight and convenient to apply. The adhesive incorporates top-tier cementitious and polymeric binders, which not only create a strong bond between the substrate and the tile but also ensure a durable finish with an exceptionally long service life. Thanks to its high flexibility, the adhesive can also compensate for shear stresses caused by the thermal expansion of materials, making it an ideal solution for deformable substrates both indoors and outdoors.
