Husqvarna Superfloor™ Gold Polished Concrete

Husqvarna SUPERFLOOR Gold is a method to create a highly polished concrete floor with a low to medium (“fine) level of aggregate exposure.

Specs

• Ra: 50
• GU: >50
• DOI: >50
• Correlating US CPC levels: Exposure Class B & Appearance Level 3 or above
• Surface Protection: If the project includes also final application of any stain protection/guard use a product from the Husqvarna Floor Protection system.

Features

The advantages are:

• Ecological - concrete consists solely of natural material
• Long service life and minimal maintenance give a low LCC cost (Life Cycle Cost)*.
• Diffusion open
• No diffusion-tight surface layer
• Easy to clean
• Improved work environment thanks to lighter and cleaner premises
• Minimises harmful vibrations for forklift drivers
• Quieter traffi c and reduced forklift maintenance
• Extremely resistant to tire marks from forklifts and other vehicles

Scope of use

The method involves grinding away the concrete skin and exposing the underlying, stronger concrete, in the form of fine material. Normally, 1 mm of the surface is ground away. The floor is ground smooth and the glossy surface makes the floor easy to clean and more resistant to tire marks from forklifts and dirt. Moreover, the light is reflected in a pleasant way

Primarily used on old as well as newly laid concrete in areas such as workshops, warehouses, public spaces, shops and domestic environments.

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 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 finished floor

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.

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 SUPERFLOOR™ process, use only water in any cleaning step (no additives, soap or detergents) since otherwise the penetration and performance of the 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.
