Fortedur

Cement dry mix

Fortedur is a uniquely designed dry powder mix combining graded hard aggregates, special cements, and compatible chemical ingredients that modify its mechanical properties and workability. The aggregates are mostly graded silica sand, sintered oxides, metallic aggregates. The quality of the dry mix, which is primarily determined by its abrasion resistance, is chosen according to the intensity of operations and the required load.

Floors modified in this fashion are found mainly in production and storage facilities, wholesale centers, logistic centers, or in parking areas.

They are especially good in places that require high resistance to abrasion and impact. Anywhere there is a need for a system with a durable, smooth and solid surface, which is not naturally slippery and has increased resistance to seepage from oil and grease.

Colorfulness of insolence

Floors with dry mixes are primarily done in a natural gray color (the color of concrete). The mixed layer can be dyed to a selected color shade based on the requirements of the customer. The final color of the floor is always a combination of the color of the dry mix with shades of gray.

Special additives in the composition

Anti-Shrinkage Agent

Anti-Shrinkage Agent is a special additive contained directly in the dry mix. It significantly reduces the formation of hairline cracks on the surface of the finished floor by providing a higher volume stability. You can therefore depend on an enhanced visual impression and improved mechanical properties of the final floor.

Silica Effect

Silica Effect – using very fine spherical particles in the dry component of the system helps reduce the porosity of the surface. This ensures lower seepage, higher frost and corrosion resistance, further increases the strength (in compression, bending tension, abrasion resistance) and improves the compactness of the entire floor system.

Abrasion-resistant micro-particles

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.

Synergies of products

To ensure the maximum efficiency of the floor system, we have added not only exceptional ingredients to the product that you won’t find in any other product of similar format, but we have also supported the functional dependability of the mutual synergies of the Fortedur powder mix and from the special Fortecoat 1425 or 1426 (water-based) curing coat.

It allows you to maximize the curing and finish of the final layer of your cement floor.

Advantages of the Fortedur system

Extra-long life of the floor in comparison with conventional concrete
High productivity and ease of installation
High resistance to operating loads
Increased impact resistance
Increased resistance against the seepage of aggressive substances (oils, solvents, etc.)
Controls the formation of dust and slipperiness of the surface
Various colors available

Disadvantages of the Fortedur system

Requires high-quality and expert application
Copies the plane of the concrete slab
Inconsistencies in color may develop in choosing color variations

Application to concrete

Evenly apply the cement-based dry mix to the surface of the concrete slab. In the event the concrete floor requires renovation, we recommend proceeding with the application in accordance with the method “Application for dry concrete”. In the opposite case, for new floors, we recommend the procedure “Application for wet concrete”.

Application of the dry mix onto wet concrete

The concrete must be ready to receive the dry mix. Before applying the first layer, excess water is removed from the concrete surface, the surface is leveled and ready to walk on (pressed by hand to a depth of 3-5 mm). The concrete surface is smoothed using a rotary disc buffer, then Fortedur dry mix is evenly spread on the surface of the concrete slab in one or two steps in a total amount of 3-6 kg/m2 (i.e. a 25 kg bag of the product can produce a 4-8 m2 wear layer).

After each application of the material, the surface is mechanically smoothed with the rotary machine using combination and final trowels, which ensures a high degree of the final physical modification. The process of smoothing with an increasing tilt of the trowel is repeated many times depending on the course of the solidification of the concrete mixture and dry mix. Prior to applying Fortedur dry mix, there can be no depressions or puddles on the concrete surface, nor can the surface be soaked.
