Fornivel

Cement-based self-leveling screeds

Cement self-leveling screeds are the final or leveling layer for seasoned concrete floors. They can help you fix unevenness of various types. This is a quick method for leveling and repairing a substrate that has become worn from years of use, or has dealt with excessive loads. It creates a continuous and smooth surface. You can further modify the coatings or keep them as the final wear layer.

Fornivel self-leveling screed is characterized by short curing times. The product is used on seasoned substrates above all in plants that require high durability, excellent flatness and adhesion to the concrete substrate.

Did you know?

What is the difference between a screed and floor coating? A compound marked as Screed is defined according to standards. This is a fine-grained material with a maximum grain size up to 0.6 mm, in exceptional cases up to 1.2 mm. It is usually applied in thicknesses of 4 to 8 mm, in exceptional cases up to 15 mm. A coating is a material with a maximum grain size up to 4 mm, in exceptional cases up to 8 mm. It is most commonly applied in thicknesses from 15 to 60 mm.

If you need a larger grain size to even out the material, we recommend our product FORTEDUR WET, which belongs to the category of cement screeds. Alternatively, there is the quick-setting screed FORCEM.

Recommendations

Fornivel is produced in powdery form, so it needs to be mixed with the appropriate amount of water. Always follow the instructions when mixing. If you fail to maintain the ratio of the compound and water, it can cause the screed to lose its firmness and not solidify throughout or else become thick way too quickly.


Special additives in the composition

Anti-Shrinkage Agent

ASA (Anti-Shrinkage Agent) is a special additive contained directly in the dry mix, which significantly reduces the formation of hairline cracks on the surface of the final floor, thus improving the resulting visual effect and at the same time improving the mechanical properties of the material. In addition, it reduces the difficulty of applying self-leveling flooring screeds.

CRYX additive

The CRYX additive creates the crystallization effect, which binds the mixing water into the crystallization structure of the substance being generated, which prevents it from escaping to the ambient environment, reduces the hardening time and primarily reduces the formation of micro-cracks.

CRACK STOP (CS)

CRACK STOP (CS) fibers. The product contains highly resistant zirconic fibers, which ensure three-dimensional (omni-directional) reinforcement of the material during the aging process and subsequently help to increase resistance to high local loads.

Abrasion-resistant micro-particles

This additive made of super abrasion-resistant micro-particles, which become part of the uppermost top layer of the finished system, gives the floor a considerably higher surface durability.

SILICA EFFECT

Thanks to the SILICA EFFECT, the use of very fine spherical particles in the dry component of the system helps to achieve a lower porosity and consequently lower seepage, increases frost and corrosion resistance, further increases the physical and mechanical properties (compressive and flexural strength and abrasion resistance) and provides higher compactness.

Advantages of the product

Extra-long life of the floor in comparison with conventional concrete
High resistance to high operating loads
Surface remains free of dust and slipperiness
Simplicity and speed of the installation
High flow rate
Good adhesion to base concrete
Fast hardening
High compatibility with Fortecoat coating compounds

Disadvantages of the system

The substrate needs to be in good condition and well prepared
Needs high-quality and expert application

Synergistic effect

Fortecoat 1410 is a specially designed base coat that perfectly prepares the substrate before the application of the dry component of the system.

Fortecoat 1420 and 1421 are specially designed coatings, whose complete compatibility with other components allows them to create a perfect uniformity manifested in a better cured floor layer and sealing it against oil and water.
