Scope of use

Husqvarna SUPERFLOOR Satin is a method to create a medium gloss concrete floor with a low to medium (“fine) level of aggregate exposure. The result is a floor that offers functionality and low maintenance but is still aesthetically pleasing. 

Satin finish is a popular application for retail areas, shop fronts and indoor public spaces

Casting

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 SUPERFLOORTM 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”.

1. The surface should be power floated. (To achieve a surface as pore-free and level as possible, thorough power floating is required).

2. The surface should be heavily troweled to obtain as smooth, dense and hard a surface as possible.

3. Normally, the concrete surface should be water hardened under plastic sheeting for 5-7 days after casting, before any grinding starts. Coarse grinding and honing can be carried out at this time while polishing is left until a later date, when moisture level in the concrete is lower.

4. The surface must not be waterlogged when impregnating. Maximum 5% water content.(This is to enable the silicate solution to penetrate and react with the concrete.)

5. If the finished floor is to fulfil class A as per Swedish Hus AMA 14, table 43 DC/1, the floor must also fulfil identical requirements before the Husqvarna SUPERFLOORTM method commences. The same also applies for class B floors. (This is very important to remember when planning. The existing concrete surface is finished by grinding. Minor irregularities can be corrected, but the grinding will be more time-consuming.

The Finished Floor

A concrete floor that has been finished to a Husqvarna SuperfloorTM, can be put to use immediately and already has characteristics 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.

The Grinding Process

The first grinding step is intended to remove the concrete skin and expose the underlying fine material to meet the level defined in section J of the SUPERFLOOR specification document.

After the first metal 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 SUPERFLOORTM 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.
