Silver is the concept to choose if you want to obtain the characteristics of a well-ground floor and a matt surface. The result is an unbeatably durable floor. The method involves grinding away the concrete skin and exposing the underlying, stronger concrete, in the form of fine material, gravel and, where possible, aggregate. Normally, 2 - 3 mm of the surface is ground away. Due to the nature of the concrete construction, the larger aggregate may be exposed unevenly in the surface.  

The floor receives a completely smooth surface with many good qualities, both functionally and aesthetically. Primarily used on old as well as newly laid concrete in areas such as workshops, warehouses, public spaces, shops and domestic environments.

For the floor to have a uniform appearance, the casting is of the greatest importance. (A poorly cast floor will be costly to grind, and even if the function of a polished floor can be achieved, the finish will be affected by uneven aggregate, cracks, etc.) The Husqvarna SUPERFLOOR™ method is not in itself a method for preventing cracks in the floor, etc. Thanks to experience from earlier examples, we can give the following tips on points to consider before casting, but please note: The designer is always responsible for ensuring the requirements are met regarding reinforcement and concrete quality as well as dimensioning. For details regarding the concrete placement, please see latest version of “Concrete and Casting recommendations Husqvarna SUPERFLOOR”.

The first grinding step is intended to remove the concrete skin and expose the underlying fine material, gravel and, where possible, stone, to the level defined in section J of the SUPERFLOOR specification document. Normally, only 2 - 3 mm of the surface is ground down. 

After the second grinding step the surface is inspected for cracks and pores. Where necessary, pores in the surface are filled with a product from the Husqvarna Floor Grouting system, if ordered by the customer. In the grinding process, the concrete surface is treated with a densifier from the Husqvarna Floor Hardening system. 

After the final polishing step*, the floor is cleaned using an auto-scrubber and diamond impregnated pad. Note: throughout the whole SUPERFLOOR™ process, use only water in any cleaning step (no additives, soap or detergents) since otherwise the penetration and performance of any floor treatment chemical might be affected. 

After cleaning, measure the surface characteristics to make sure the end result is according to expected specifications and what has been agreed upon prior to work. The recommended surface specifications shown below are general objectives, and might vary some depending on specific floor characteristics. It is important that contractor and customer always agree upon specifications prior to work.

A concrete floor that has been finished to a Husqvarna Superfloor™, can be put to use immediately and already has characteristic such as smoothness, high cleanability, good friction as well as high resistance to wear and great durability. The floor is very easy to clean and to maintain these characteristics it must be cleaned following the instructions as described in the document “Maintenance instructions_Husqvarna SUPERFLOOR” The cleaning is completely free from chemicals and only uses pure tap water as additive. Because concrete is mainly a natural material, it can be an advantage to add natural stone soap, when needed, to the cleaning process. 

If finishing has been carried out using Husqvarna Floor Protection system, the floor has an increased protection against stains, which means that most liquid spills can be wiped up within 30-45 minutes without any residual stains. 

For newly ground concrete floors: Avoid letting residual water in the form of pools/rivulets dry out/evaporate as this can cause a reaction in the form precipitation or permanent variations in the surface. The resistance increases with time and after approx. 2 months, reactions are not likely. However, large quantities of liquids should not be left to dry on the floor because a Husqvarna Superfloor™ is not a sealed floor. Concrete does not withstand corrosive substances such as strong acids and alkalis, which must be removed immediately. If the floor is covered with protective material**, it is important that the entire floor dries out at the same rate, because it would otherwise result in permanent color differences. Do not use tape directly on the concrete.
