Naxos ceramics are made through the use of two production technologies: the exquisite white base for the products to be used for interiors, and fine porcelain that is suitable for both indoor and outdoor areas.
WHITE PORCELAIN PRODUCTION TECHNOLOGY
White porcelain is a light and lightweight ceramic. Its production process begins with the grinding of a mixture of top quality raw materials (clays, sands, carbonates) which leads to the creation of a liquid compound that is commonly called “slip”. The slip is finely atomised until it becomes a fine and homogeneous granular powder mixture that is suitable for pressing. After formation of the tile by pressing the mixture, the subsequent firing at temperatures higher than 1,100° C permits the vitrification necessary to give the white tile its exceptional brightness, intensity of colour, resistance, compactness and non-absorbency of enamel that render it unique. Products made of the white mixture are lightweight and ductile, features that facilitate the handling and laying process. The wide variety of colours and the availability of numerous sizes allow the customisation of interior spaces, with different installation solutions that can be created along with the pairing of graphics and colours according to subjective tastes and design needs. Naxos white body products are part of the BIII group according to UNI ISO 13006 / EN 14411 standards (absorption> 10%, breaking load> 600N, maximum regularity and dimensional stability).
FINE PORCELAIN PRODUCTION TECHNOLOGY.
The production process of fine porcelain begins with the grinding of a mixture of top quality raw materials (clays, sands, feldspar, kaolin) which leads to the creation of a liquid compound that is commonly called “slip”. The slip is finely atomised until it becomes a fine and homogeneous granular powder mixture that is suitable for pressing. After the formation of the tile by pressing the mixture, the subsequent firing at temperatures higher than 1,250° C permits the vitrification necessary to give porcelain its exceptional hardness, strength, compactness, impermeability and resistance to frost that render it unique.
Naxos creates glazed and unglazed products in fine porcelain under the BIa group, defined by the UNI EN ISO standard as that with the best technical characteristics (absorption <0.1 %, breaking load> 1,300 Newton, maximum regularity and dimensional stability, etc.).
NAXOS DECORATIVE PRODUCTS
In the decoration Naxos products use the DJS system (Digital Jet System), which, using equipment for decoration without contact, is able to reproduce the refined and complex aesthetic of natural stone, marble, textiles, wood, mosaics and more traditional ceramics. Naxos products also use equipment within the production cycle that can perform line processes such as rectification (perfect squaring of the material) and lapping (polishing of various levels and depths) that add both an aesthetic and technical value to materials.
The range of products that Naxos offers its customers comes in a variety of sizes that are suitable for both flooring and wall cladding, starting from mosaics with 2.5×2.5 cm tiles up to the large 60×120 cm format, available in thicknesses between 7 mm and 20 mm.
Naxos is able to offer a wide range of collections and ceramic solutions thanks to its constant pursuit of quality and continuous, significant investments in research and innovation, with the most advanced technologies in the sector and highly qualified personnel.

CERTIFICATION FOR WORKER SAFETY
Naxos ensures compliance with the highest standards of health and safety in the workplace, and considers them requisite values. The company is constantly committed to preventing accidents in the workplace and protecting the health of its employees.
Naxos has pursued an attentive corporate environmental policy for many years. The entire production cycle offers special guarantees for environmental protection. All of the products of the group are manufactured using raw materials with low environmental impact, and require limited consumption of natural resources such as water and methane. The electricity used is self-produced through a cogeneration system, which dramatically reduces atmospheric emissions. All wastes are reused in the production cycle. All refuse from activities unrelated to production are carefully collected, differentiated, recycled and disposed of. Every phase of product creation (raw material extraction, glaze preparation, glazing, firing, sorting and packaging) takes place with the utmost respect for man and the environment, through an analysis of the entire product life cycle. The various certifications obtained by Naxos products show that the company prioritises having an industrial eco-sustainability model.
In accordance with ISO 14021 requirements, many collections produced by Naxos contain recycled materials, guaranteeing that architects / designers that use them obtain credits under the LEED building energy eco-evaluation rating system.
Naxos products are LEED compliant. LEED is a rating system for the environmental performance of buildings, which promotes integrated and sustainable planning for an entire building throughout its life cycle. The LEED system defines the standards that characterise the environmental impact of the building during the phases of design, construction and maintenance.
Naxos is a member of the Italy Green Building Council, an association that serves for the consolidation and dissemination of the LEED rating system.

Before installation, it is important to carefully check the colour, size and choice of material. Claims are not accepted for materials installed whose defects were visible before laying. It is recommended that materials are ordered with an excess of 10 to 15% relative to the surface to be covered, in order to carry out repairs or perfectly match the colour of one tile to the one laid previously.
During installation, we advise you to use material from several boxes, especially if it comes from a range with a degree of colour shading and chromatic variation higher than V = 2 (refer to the general and collection catalogues). For veined products, such natural stones, it is recommended to arrange the grain of the slabs so as to obtain the best aesthetic and chromatic effect.
Installation can take place by either using cement dust or glue, with the use of specific high-performance adhesives for fine porcelain. It is advisable to use glue as it offers a more guaranteed grip, especially with large-sized products. At the time of application, the substrate must be flat, stable, dry and cured, neither frozen nor excessively hot. Follow the manufacturer instructions for the substrates and the specific adhesives used. Cementitious adhesives must be applied at room temperature, generally between + 5° C and + 30/35° C. For installation, it is recommended to follow the technical time frames indicated by the manufacturer of the adhesives used. The most suitable adhesives for laying porcelain and white tiles can be identified based on the European Standard EN 12004 currently in force. For lapped/polished products (and ideally for all other products), do not mark the material on its usable surface during installation with pencils (graphite) or permanent markers.
The use of double spreading is recommended for laying tiles with a side longer than 60 cm in order to have a compact layer of adhesive as required by the UNI 11493 installation standard.
JOINTS AND GROUTING
The joint width can vary according to the size of the tiles and intended use of the flooring. The use of a single joint is not recommended; installation is recommended with a joint of at least 2mm for for rectified products and 3 mm for non-rectified materials or for materials for outdoor installation (this type of installation enables greater grip of the grout on the sides of the tiles, greater absorption and compensation for any movement of the substrate). The regular use of expansion joints is advised in large areas; for smaller areas, a slight gap may be left between the material and perimeter walls. Skirtings will then cover the gap, giving a finished appearance. Always refer to the recommendations / suggestions of the designer or site manager.
For the continuous installation of rectangular products, we recommend staggering the longest side by a maximum of 10-15cm along the length of the adjacent piece. For large formats (as also provided for by UNI 11493) we advise use of the double spreading technique: the glue must be applied to both the back of the tile and on the wall/floor, thus ensuring the absence of gaps between the ceramic and support. During the installation of products, the floor may be covered with fabric sheets or paper/cardboard in order to prevent any residual materials from scratching the surface of the floor.
For a greater aesthetic value, we suggest using grout in a colour that complements the tiles so as to reduce contrast, especially for lapped and rectified products. After grouting the porcelain tiles, it is important to remove any excess grout immediately with a sponge and plenty of water while it is still wet.
LAYING FINE PORCELAIN ON PRE-EXISTING FLOORS
Before installation, check the evenness of the surface and level if necessary. Fully clean the surface to remove all traces of wax, oil or residue that could compromise adhesion.
Use 2 mm joints and perimeter expansion joints. Respect all expansion joints underneath.
Spread the adhesive on the floor with a trowel; also spread the adhesive on the slab to be installed using the flat side of the trowel, in accordance with the “double spreading” method.
In certain cases, it can be useful to cover edges and corners with additional adhesive.
Lay the slab and remove air gaps by carefully tapping the surface to promote full adhesion, ensuring that the joints are free from adhesive.
INSTALLATION OF WALL COVERINGS
White and fine porcelain tiles must be installed on interior walls as follows:
Ensure evenness of the surfaces, levelling if necessary.
Use joints of at least 2 mm, respecting the use of expansion joints as below.
Spread the adhesive on the wall using a suitable trowel.
Lay the slab and remove air gaps by carefully tapping the surface to facilitate full adhesion.
Use the most suitable porcelain/white tile adhesive for the type of wall being covered.
OUTDOOR INSTALLATION OF FINE PORCELAIN
When laying fine porcelain outdoors, ensure the proper sizing of joints and an appropriate pattern of elastic joints as a function of the substrate, and the size and layout of the facade.
For successfully laying ceramic flooring in exterior areas, it is essential to select and use high quality tiles, but equally important to have an experienced designer present who can adapt the installation system as a whole to the specific loads required and the static situation of the surface on which it is laid. The sub-flooring layers must be suitable for such loads, taking the potential need to use welded mesh into consideration in order to prevent any settling. The use of expansion joints, the application techniques of the bed and the tiles must be carried out in accordance with the TECHNICAL REPORT CEN / TR 13548 “General requirements for the design and execution of ceramic tiling.” Guidelines for the installation of Finibec Group flooring outdoors are provided below.
1) Use of enhanced malleable cementitious adhesive, with extended open periods (class C2E S1 according to EN 12004) for sizes up to 25x25cm on cement screeds, structures in cast concrete and waterproofing.
2) Use of enhanced malleable cementitious adhesive, with extended open periods (class C2E S2 according to EN 12004) for larger tiles on cement screeds, structures in cast concrete and waterproofing.
3) Use the “double spreading” technique by means of a toothed trowel so as to have a full bed: this prevents the formation of gaps that could cause the stagnation of water, with the accompanying risk of an increase in volume due to frost and the consequent detachment or breakage of flooring.
4) Use joints of not less than 3 mm and the application of expansion joints (width not less than 5 mm and utilised at least every 9-12 m2) to bear heavy stress due to night-time/seasonal temperature changes, in order to create a support for fine porcelain that has virtually zero coefficient of expansion.
5) Project slopes must be regular, and at least 1.5% in order to allow the easy run-off of liquids. This must be created within the structure or by preparing a special sloping screed; varying the thickness of the bed to create a slope, as in the case for traditional cement laying, is not recommended.
CLEANING AFTER INSTALLATION
Cleaning is required following installation. Inadequate or late removal of grout used on joints may leave hard-to-remove marks and create a cement film on the flooring that absorbs dirt, thus giving the impression that the material itself is dirty.
Joints with grouting cement (class CG – EN 13888): to remove excess grouting cement, wash the floor with a solution of water and buffered acid (percentages of water / acid as shown on the packaging).
We recommend the use of the following products:
Deterdek – Fila
Delta Plus – Kerakoll
Keranet – Mapei
Cement Remover – Faber
Solvacid – Geal Bel Chimica
b) Grout joints with epoxy filler (Class RG – EN13888) (not recommended for textured or lapped / polished surfaces until after on-site testing): It is critical not to leave epoxy residue – remove all excess material from the surface of the tile before it begins to harden, as subsequent removal could prove extremely difficult. If residue and rings of epoxy grout are present, use a specific product and follow the instructions of the manufacturer.
We recommend the use of the following products:
Fuga-Soap Eco (Kerakoll)
Epoxy Residue Remover (Faber Chimica)
Eposolv (Geal Bel Chimica)
For both types of grout, we recommend first collecting the dirt and rubbing the detergent (diluted according to manufacturer instructions) onto the tiling using a colourless cloth. We suggest performing a preliminary wash on a surface sample of a few square metres. If the result is positive, clean to the entire surface area and prevent the above detergents coming into contact with special or decorative pieces and elements in aluminium, steel, natural stone (e.g. marble). While the cleanser is active (as established the manufacturer on the label), scrub the dirt and grime with Scotch-Brite pads or a cellulose sponge. Rinse the floor with water to ensure that it is free of detergent and dirt residue. For polished/lapped materials and special or decorative pieces, be sure to proceed with cleaning of excess grout and cement mortar before they dry, in order to avoid the subsequent use of abrasive sponges on shiny surfaces that could lead to scratching.
After the acid wash, it may be necessary to perform a basic or alkaline wash with the use of degreasing detergents. This is due to the fact that an acid wash can leave an oily film on flooring that could attract dirt. We recommend the use of the following alkaline detergents:
Fila PS / 87 – Fila
Wax remover – Faber Chimica
Deterflash – Geal Bel Chimica
ROUTINE MAINTENANCE AND DAILY CLEANING
When cleaning after installation (previous chapter), use a neutral detergent diluted in hot water in for the proper maintenance of Naxos ceramic surfaces, always following the instructions specified on the packaging. Please pay close attention when rinsing and drying the flooring/surface, which allows for the removal of dirt and to avoid accumulation (stratification) of limescale, detergent and dirt residue. We recommend the following products for this purpose:
Fila Cleaner – Fila
Floor Cleaner – Faber Chimica
Bel Gres – Geal Bel Chimica
We strongly advise against the use of waxes, oily soaps, impregnating agents and hydro-oil repellent treatments on porcelain products where their application is not necessary.
Hydrofluoric acid (HF) and its derivatives irreparably damage all ceramic products, so it is always important to ensure that products containing these chemicals are not used (sometimes present in special cleansers for bathrooms, showers, etc.).
In the event of seizable and/or particularly stubborn stains, or for special cleaning of the entire surface, it is advisable to use specific detergents as indicated in the table below. It should also be emphasised that the removal of any type of stain is easier if it is removed while still fresh. For lapped or polished porcelain tiles, it is important to perform a preventive test before using detergent products.
