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.

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.
