Material

In Italy, a country that is well-known for its stone industry, large blocks of stone are imported from different quarries around the world. They are sawn into workable panels on large frame saws. Subsequently they are finished using grinding machines equipped with diamond studded tools. Polished, honed and structured brushed surfaces are also produced. The panels are machined with the aid of state-of-the-art, CNC-supported stone saws and CNC machining centres.
The gluing and chamfering of workpieces is carried out in precise and expert craftsmanship.

Product features

The commonly used "granite" often serves as a symbol for various rocks that are similar in colour, texture, grain, chemical composition, mineral content, and origin. The main components of these deep rocks are feldspar, quartz and mica. However, these rocks differ in terms of their secondary constituents, petrographic determination (for example, the quartz portion) and thus ultimately also their technical properties, such as water absorption or compressive strength. A globally uniform name for natural stone does not exist. Only within the scope of the EN 12440, natural stones are classified by their name in terms of their scientific names by petrographic examination. In general, these are classified according to the way they are formed into magmatic rocks (including granite, for example, syenite or rhyolite), sedimentary rocks (such as sandstone or limestone), and metamorphic rocks (such as marble, gneiss or slate). In its natural appearance, natural stone reflects the origins of our earth. Inclusions, pores or quartz vein processes, injections, opacities are natural phenomena that are not a cause for complaint. Colour and structure deviations to the samples you use in the purchase decision do not affect the quality of the material in any way and therefore cannot be used for claims for value reduction or free replacement deliveries.

Surfaces

Polished surfaces are highly compacted and have a low liquid absorption. Therefore they do not require any further surface treatment. Matt surface finishes are open-pore and therefore much more sensitive. They require a protective treatment in the form of an impregnation in contrast to polished surfaces.

Breaking strength

The risk of breakage is usually only present if the material is not handled properly. Transport and handling may only be carried out in a vertical position. The panels must not be used as a step for window cleaning or replacement of light fixtures. Excessive point loading, for example, in the thinner areas around the sink and the hob of worktops presents a risk of cracks in the worktop.

Scratch and cut resistance

Hard rock like granite is very scratch resistant and resistant to cutting. In order to avoid hard-to-remove metallurgy traces and for reasons of maintaining your cutting tools, we recommend the use of suitable cutting board for kitchen this purpose.

Acid resistance

Hard rock such as granite with low liquid absorption in polished surface is resistant to normal household acids such as citric and acetic acid.
Food colouring such as coffee, tea, wine, mustard, vegetables or fruit do not leave any non-removable traces. Nevertheless, we recommend that you remove any contamination as soon as possible and not to let it dry.

Contact with aggressive chemicals or high-alkaline cleaners can lead to irreparable damage.

Heat Insensitivity

The material is heat-insensitive. Short-term stored hot pots can generally not cause any damage. Panels with very high temperatures can cause discoloration in the material over a longer period of exposure. Since cracks can also be caused by shock heat input, we recommend the use of suitable pot holders for placement of hot pans, pots, baking sheets, etc. coming directly from the cooking area or from the oven.

 

Formats

Our selected natural stone slabs are mainly available in thickness 2.0 cm. The dimensions of the raw panels are approximately 2500 x 1200 mm. Other formats and strengths can only be offered on request. Solid panels in 2.0 cm full thickness are divided into worktops, for example, and reinforced with OBJECT STONE's proven support system. This results in compact, unbreakable working surfaces in side profiles of 4.0 and 6.0 cm, which due to their reduced weight are particularly handy and easy to mount against solid material and still offer a massive view. Back wall panels are made of 20 mm thick solid material. Natural stone worktops can also be combined with quartz composite for back walls and back splashes.

Worktop Surfaces

OBJECT STONE offers product groups with different surface finishes which, in addition to their usage characteristics, are particularly distinguished in appearance and soiling behaviour. Polished surfaces are smooth and glossy, whereby colour and texture are well expressed. Satin surfaces are manufactured in two working steps. By natural stone, this type of surface finish is first milled and subsequently processed with diamond brushes. This results in a leathery, matt surface finish without lustre, which has slight elevations and depressions. The surface finish Caress is first produced similar to a satin surface but using special brushes and a subsequent special polish of the elevations. The achieved surface finish has partially matt depressions and polished elevations. All natural stone surfaces are pre-treated in the factory with an impregnation applied to the surface to protect against soiling.

OBJECT STONE offers cleaning and care products adapted to the respective products. The following procedure applies to worktops made of quartz stone:

Surface Finish Appearance Treatment
polished glossy required, done in-factory
satined matt required, done in-factory
caress matt, glänzend matt, glossy

Cautionary measures

Processing attempts after production such as cutting, drilling, grinding can lead to irreparable damage. Coarse scrubbing sponges, steel wool or steel pads must never be used for any purpose whatsoever. Ink, printing ink, text markers, nail polish remover, paint remover, lacquer remover, oven cleaning products, drain cleaner, solvent and bleaching agent, washing benzene must not come into contact with the worktop. Cleaning agents such as alkaline cleaners with a pH of more than 10, strong acid detergents, scrubby milk, chlorine-containing detergents, baking oven spray and aggressive fat remover must not be used. Aggressive chemicals such as sodium hydroxide, caustic soda, battery acid, hydrofluoric acid must also not be brought into contact with the work surface. If these agents reach the surface, they should be removed as soon as possible using a neutral detergent and then rinsed several times with clear water.

We recommend the use of suitable cutting pads to prevent the removal of difficult metallurgy marks and to protect your cutting tools.

Cooking pot bottoms with very high temperatures can cause discoloration in the material over a longer period of exposure. Since cracks can also be caused by shock heat input, we recommend the use of suitable pot holders for storing hot pans, pots, baking trays, etc. coming directly from the cooking hob or backing oven.

The worktop should not be used as a step for window cleaning or replacement of light bulbs, due to the risk of cracking caused by the point load weakness in the sensitive edge areas of the sink and cooking field of the stove.

Cleaning

Cleaning and maintenance of polished surfaces

For daily cleaning of light stains on polished granite worktops, wipe with a damp cloth or the yellow side of a Scotch-Brite pot cleaning sponge. Use neutral cleaners, e. g. cleaner, cleaning agent without care additives, glass cleaner etc. or the cleaning product Lithofin MN EASY-CLEAN, which you get in a set with the delivery of the worktop or, if necessary, order by OBJECT STONE or in specialist stone retail shop. Please follow the instructions given in the enclosed maintenance instructions and observe the manufacturer's instructions regarding application, processing and disposal.

Stubborn stains or strong crusted areas caused by dried food or other substances can be mechanically removed with plastic spatulas.
Afterwards you should clean this area with a neutral cleaner, such as found in the care set that is supplied with the worktop. We recommend the use of the MN EASY-CLEAN. Eventually a prolonged soaking in time will be necessary

Cleaning and care of polished, satined, antique or brushed surfaces

TOP STONE worktops made of natural stone in the previously mentioned matt surface finishes are given a factory impregnation to protect against the effects of oil, grease or colouring substances. The daily cleaning of impregnated natural stone worktops can be carried out as with polished surfaces with a neutral cleaner such as the MN EASY-CLEAN contained in the maintenance set. Especially stubborn stains or encrustations must be mechanically removed using plastic spatulas. If more intensive cleaning is required, this can be done in the same way as work surfaces with a polished surface with MN EASY-CLEAN and a possibly longer exposure time. Since the existing impregnation decreases in its protective effect depending on the degree of wear and tear, it is advisable to replenish this impregnation from time to time. However, before the impregnation, the entire worktop should be free from residues and, if necessary, be cleaned again! After the basic-cleaned work piece has been dried, the protective impregnation can be applied.

Lithofin FLECKSTOP W is a solvent-free and low-odour special impregnation for natural stone which, in addition to the water-repellent effect, also protects from grime such as oil and grease and prevents staining.

Caution: Impregnation that cannot be absorbed by the stone should not be allowed to dry on the surface, but should be removed or rubbed with a dry, clean cloth! It is recommended to work on a trial surface area beforehand, since some natural stones can be slightly coloured. Please read the care instructions and instructions supplied by the manufacturer before use. In case of inadequate or delayed removal of excess impregnation liquid, dark spots or streaks may occur. The information on cleaning and care products of the manufacturers on the packaging must be followed. This particularly applies to existing disposal and warning notices, as well as the call for the use of protective equipment and, if necessary, protective measures!

Assembly

Instructions and recommendations for the assembly of worktops

Packaging, transport

The worktops are packed and stored in a professional manner after completion of production, quality control and the preparation of photo documentation: either on a forklift or pallet truck, transportable one-way wooden A-frames or on multi-way transport frames made of steel. The A-frames and racks must always be stored indoors during eventual inter-transport reloading! Upon receipt of the goods, the consignment is to be checked for damage, completeness and accuracy of measurements. Special attention should also be given to the cut-outs, type and number of edge processing (comparison with drawing) as well as any obvious defects. Complaints must be reported in writing immediately, but at the latest within 7 working days from dispatch. After the expiry of this period and after any assembly, no complaints of obvious defects can be accepted.

Handling, Breaking resistance

TOP STONE worktops with edge profiles higher than the actual material thickness are reinforced by a high-quality, stable support construction. The risk of breaking through is generally only given if the work piece is not properly handled. Transport and handling should only be carried out in a vertical (upright) position. Special care must be taken when handling the parts with cut-outs. There is an increased risk of damage by transport in a horizontal position due to the thin areas between cut-outs! Do not stand on the worktops to clean windows or to replace light bulbs. This creates the risk of a point load, which can lead to the formation of cracks, especially in the sensitive edge areas of the sink and the cooking area.

Precautions

Eventual attempts of own processing such as cutting; drilling or grinding should be avoided and generally only carried out by a specialist company, since this can otherwise lead to irreparable damage. Point loads, as well as inadequate alignment of the support cabinets, regarding uneven horizontal levelling, can lead to cracking. Please be sure to refer to our information on the worktop surfaces and protrusions. Particularly in the cut-out areas of the worktops, sufficient, possibly additional supports, must be added to ensure an even load acceptance. For the installation of under-mount of basins, mounting aids are installed or supplied from the factory. The installation of the basin on the underside of the stone slabs can be done without any problems. Built-in devices intended for the purpose of heating or cooling must be insulated in such a way that, a drastic exposure of temperature into the stone is avoided!

The room and object lighting must be positioned with a sufficient clearance to the stone surface. The illuminating body and the illuminate must correspond to the state of the art and must be equipped with the specified UV filters

Assembly

Before assembling the worktops, it is imperative to check the differences for absolute levelness, load bearing capacity and torsional strength. Multiple-part worktops are to be placed on existing or to be constructed supports and to be aligned flush together. The worktop elements must be installed free of any tension and must never be fixed with screws. Any eventual unevenness in the surface regardless of how slight must be compensated for by flat underlayment parts.

Wall joints of at least 5 mm must be made, which can be covered by splashback strips, or can be sealed with neutral-curing silicones. Butt-joint sealing should also be made with natural stone silicones. Before applying silicone, the worktop surface should be protected with adhesive tape. Do not apply any silicone or adhesive on the surfaces of the worktops! The drying or even curing should be avoided (remove fresh silicone or glue residue immediately by cleaning).

Back wall panels or splashbacks made of quartz stone are to be installed using fast setting cement adhesives or with natural silicones.

If TOP STONE worktops are combined with other materials such as glass, steel or wood, a flexible fixation of the panel as well as a flexible filling of the joint must be made in order to absorb possible expansion of the different materials. Please refer to our data regarding the different thermal expansion coefficients. Cut-outs for cooking zones and sinks are produced with corner radius of at least R = 3 mm. A minimum of 3 mm all-round gap for ceramic panels and 1 mm for sinks must be taken into account in order to prevent possible expansion of the devices and dimensional tolerances of the manufacturers.

ATTENTION!

  • The workpieces are fragile!
  • Worktops may only be transported in an upright (vertically) position.
  • Support cabinets must be prepared strictly level.
  • The worktops must not be screwed in any way.
  • Make sure that the unevenness is balanced by using underlayments over the entire length, glue in place and do not screw it together.
  • Ensure tension-free resting of the worktop on the support cabinets.
  • Do not apply any silicone on the worktop; tape the edges of the worktop accordingly.
  • Flush cut-outs (hob or sink) have tolerances in the fold depth, which must be compensated by underlayments.
