ASTONE is a completely homogeneous material throughout its structure, it does not separate into layers and is resistant to thermal shocks and impacts.

Material is stable when exposed to UV radiation and has better resistance to heat than other materials, ensuring that brief exposure to high temperature, such as cigarette ash and hot oil, will not damage it. ASTONE material is completely impervious to most chemicals and is completely non-porous, which among other things makes it ideal for places like hospitals, laboratories and health clinics.


ASTONE is a very thankful material that is suitable for many different types of processing: cutting, sawing, drilling, grinding, forming into different shapes, and seamless joining. The material is mechanically processed by using carbide tools.

Depending on the chosen abrasive and polishing medium, the surface layer can be shiny or matte. Therefore, ASTONE is an ideal material for design process, and we will be glad to help you turn your ideas into reality in terms of preparation and processing of ASTONE material.

The matte finish is recommended for working surfaces prone to intensive wearing, while shiny finish is less resistant and has mainly decorative purpose.

Besides complying with the highest technical criteria, ASTONE also fully meets the most important one- hygienic.Since it is a completely non-porous material, bacteria and fungi have no development potential, which guarantees the safety of this material from a microbiological point of view. When the surface of ASTONE looks clean, it really is clean.

Hygienic aspect

When applied in bathrooms and sanitary facilities in form of integrated washbasins where the connection between the washbasin and panels is made without visible joints, accumulation of dirt is completely prevented as well as possible development of fungi, thus providing the highest hygienic standards.


Production of ASTONE material does not pollute the environment and does not release greenhouse gases. Material itself can be recycled directly. ASTONE was tested by IGH and the Public health institute of Zagreb.

Consequently, ASTONE is not harmful to health and contains no hazardous substances. This material belongs to a group of self-extinguishing materials (class B non-combustion) and does not release toxic or corrosive gases.

Cleaning and maintenance

ASTONE is very easy to clean and maintain! All you need is a sponge, water and a degreasing agent (eg. dish detergent). It can also be cleaned with alcohol or detergents intended for ceramics. To remove limescale, use a sponge soaked in vinegar or a cleaning agent based on vinegar or citric acid. Then wipe the surface with a dry fabric and you are done!

For regular cleaning

Although liquid cannot penetrate the ASTONE material,
it is the best to immediately wipe any stains with a soft cloth.

Rinse thoroughly with warm water and use a soft cloth of microfiber
in combination with ordinary detergents or household cleaners.
Always clean with circular motion.

For regular cleaning

Stains of coffee, tea, fruit and vegetable juices, red wine, ketchup, ink, pencils, paints, etc. immediately wipe with a soft cloth and rinse with warm water.

Use a cleaning cloth (Vileda Glitzi, Scotch-Bride) for matte surfaces and clean with a diluted bleach (3: 1) or a fine abrasive cleaning agent that is also suitable for stainless steel. Wash the surface several times with warm water and wipe with a soft, dry cloth. Use a soft cloth and fine polishing agent to clean glossy surfaces.

To remove stains from limescale and minerals, disperse the household scouring agent used to remove limescale (kitchen cleaner) or kitchen vinegar to the surface and allow it to work for 2-3 minutes.

Take a soft, microfiber cloth and rub with circular movements. Rinse the surface several times with warm water and wipe with a soft, dry cloth.

Scratches and small imperfections

As ASTONE is entirely homogeneous material, its material can be completely restored if slightly damaged.

Deeper scratches should be grinded with sandpaper of 180 – 220 granulation until they disappear. Continue by applying 320-400 and 600 granulation sandpaper and clean the entire surface with a finer abrasive cleaning agent. Gloss surfaces should be grinded with sandpaper of granulation 600-800 or more. This process requires experience, so we advise you to contact our service department for this type of repair.

Washbasins and kitchen sinks

Once or twice a week perform basci cleaning on your washbasin and kitchen sink. To remove all grease and other stains that occur during normal food preparation use stronger surface cleaning agents.

Prepare spray with ¾ chlorine and ¼ water and spray prepared mixture on the surface and leave for 10 minutes. After finishing the process, wash the surface with hot water and wipe it with a soft cloth. You can use the same mixture to fill the washbasin or kitchen sink and let it to work for 10 minutes. After the procedure, rinse the surface thoroughly with hot water and wipe it with a soft, dry cloth.
