Adesivix Fibro

Fiber-reinforced C1TE tiles adhesive

Fiber-reinforced single-component cement adhesive with good support adhesion, composed by selected granulometry sands, redisperdible polymers and rheological addictives. Easy to apply, with an prolonged open time (E), slip resistance (T) and elevated adjusting times and thixotropy, EN 12004 C1TE class certified.


Fields of application

For application on mosaic, majolica, porcelain gres etc. Both floors and walls. Can be applied on cement supports such as plasters, cured/leveled concrete and screeds (if properly cured and dry).


Surface must be plain, stable, solid, free from dust and dirt. Supports must be cured and dry, not subject to shrinking after the application of tiles. Recover excessive gaps with a smoother (RasaPro) or self-levelling plasters (Level floor). In the presence of rising damp treat in advance with proper primers (Primer Bv 2K).

On excessively hot surfaces due to sun exposure, it is recommended to wet the surfaces with water, avoiding superficial stagnations.

Mixture preparation

Pour in a container about ¾ of the necessary water to mix a bag of Adesivix Fibro, add gradually the powder and mix with a low-rounds stirrer. Proceed by adding the remaining water until an even, clump-free mixture is achieved. Let rest for 5-10 minutes and mix briefly before usage.

Tiling application

Apply a thin glue coating with the smooth side of the spatula, pushing vigorously against the support and immediately apply the mixture with a saw-tooth spatula (using the correct size, depending from the size of the tile). During application make sure the adhesive did not form a superficial film. Do not wet the glue after application, as the water may form an anti-adhesive film. Accurately beat the tiles to allow perfect adhesion. With outdoor extruded materials or in overlapping with size exceeding 25X25 cm, it is recommended to apply a double application (both on support and tile).


It is recommended to mix with clean, non-brackish water. Do not add bonding agents, inerts or other materials. In the presence of high temperatures or dusty supports wet the surface in advance with water. Sun and wind exposure may cause the rapid formation of a superficial film. Described times shortens in hot environments and prolongs in cold environments. Apply between +5°C and +35°C. Do not apply on concrete surfaces subject to noticeable shrinking or shocks. Do not apply on heating floors or metallic surfaces.
