The fibres additionally reinforce rigid cementitious matrix structure of the rendering mortar. Thanks to the unique combination, it is durable and can stand high impacts. Fibres create a kind of dispersed reinforcement, which strengthens rendering mortar’s surface and makes its layer double support - by fibres within its structure and by perfectly compatible glass fibre mesh embedded.

Fibre Force – how it works?
Fibre Force technology is a synergistic combination of mineral and natural fibres used in Ceresit ETICS adhesive rendering mortars which provides additional reinforcement to the rigid cementitious matrix of the mortar.
The reinforced matrix of the mortar, performing under stress in difficult weather conditions, is more flexible and less susceptible against thermal tensions.
Rendering mortar strengthened by this unique fibres combination is durable and can stand a high impact. Additional 3D structure of the fibres within a matrix helps to dissipate impact energy and reduce number of microcracks.
The fibres improve also the post-cracking behavior using mechanical bonding the already microcracked material and blocking further crack propagation.
Ceresit ETICS adhesive and rendering mortars with Fibre Force technology provide:
matrix of the mortar performing under stress in difficult weather conditions is
more flexible and less susceptible against thermal tensions.
Fibre Force specific three-dimensional matrix, in combination with a glass fibre mesh, creates an interpenetrating and complementary configuration that gives excellent flexibility and elasticity.
Additional 3D structure, which fibres create, helps to dissipate impact energy and reduce number of microcracks.
Thanks to its excellent flexibility, the mortar with Fibre Force in combination with a glass fibre mesh, prevents the formation of cracks, micro scratches and compensates stress derived from external factors (like large temperature amplitude of over 90°C).
The fibres improve the post-cracking behavior by mechanical bonding the microcracked material and blocking further crack propagation. Therefore we can treat the reinforcing mortar with Fibre Force technology as an innovative composite material.
With easy mixing, a smooth homogeneous mass of the high plasticity is achieved. Water retention is optimised, which allows for perfect embedding of glass fibre mesh, its compatibility with fresh mortar layer and extended usage time of the fresh mortar and its optimal skin aging time. It is especially important while working on large facade surfaces or during challenging temperature and humidity conditions.
In addition, the reinforced layer made with mortars containing Fibre Force fibres is smooth and thus makes it easier to carry out work related to priming or plastering.
Flexible and impact resistant rendering mortar with Fibre Force technology, enables extended durability of the entire system, which means resistance to thermal tensions, mechanical impacts and humidity effects.
Rendering mortars with Fibre Force technology are also resistant to water uptake and vapour permeable. Being finished with flexible CT 74, CT 75 Silicone Self Clean silicone plasters or CT 174, CT 175 Silicate-Silicone Aquastatic silicate-silicone plasters, both with Double Dry technology (hydrophobic, very low water absorption and high vapour permeability) they strengthen technical and utility values of the entire insulation system.
Synergy between low-absorbent, highly vapour-permeable, simultaneous flexible plaster coatings and Fibre Force rendering mortars, in which the fibres function as dispersed reinforcement, results in a more flexible and weather proof system. As a result, it becomes even more resistant to external factors such as high temperature amplitudes or humidity conditions and has an influence on the overall durability of the system and its weather and impact resistance. Another advantage of system’s high resistance to microcracks formation and stresses coming from temperature high amplitudes are extended coloristic palettes for the plaster as a final coating.
For standard thermal insulation systems, it is recommended to use plasters in colours with light reflectance value HBW/LRV >25% - that is colours in rather light shades. This is due to the fact that absorbed solar radiation contributes to the occurrence of thermal stresses. This is a phenomenon that causes microcracks, and sometimes even deterioration and falling off some parts of the facade’s system.
In Ceresit Self Clean or Aquastatic systems with Fibre Force technology renders CT 85 or CT 190 and Double Dry technology based plasters - silicone CT 74, CT 75 or silicate-silicone CT 174, CT 175 - one can go with colour choice further and choose the darker one with HBW/LRV = 18% and above.
Unique combination of fibres stopping microcrack in rendering mortar
The dispersed fibres are well anchored in the cementitious matrix of the mortar and this way designed to suppress crack propagation and to transfer some of the internal forces after scratching. Where the scratch has been retained by the fibre, it ensures material integrity.
