Porcelain stoneware - technical specifications

This is why our tiles are ideal for locations with high foot traffic. Its low porosity makes it frost-resistant and classified as Bla according to standard UNI EN 14411, due to a water absorption of less than 0.1%.

The chemical resistance to acids and bases (UNI EN ISO 10545-13) makes it ideal for locations where aggressive products, such as chemical agents are used: i.e. hospitals, chemical and pharmaceutical industries and the food industry.
Porcelain stoneware products are available in a large range of formats and finishes: natural, polished, lapped, patinated, structured and bush hammered.

Porcelain stoneware - laying recommendations

Porcelain stoneware can be laid on all supports that are usually used in the building industry, such as:

  • concrete
  • cement screed
  • substrates with heating coils
  • anhydrite screed
  • cement and plaster based plasters
  • existing flooring
  • wood
  • metal

The supports used for laying porcelain stoneware must be dry, stable, solid, mechanically resistant, perfectly level and free of removable parts (dust, grease, oil, wax, paint, braking agents and anything else that could compromise its adhesion). They must be suitable for loads and support the stresses for the specific use. Cement screeds must be completely set and any underfloor heating system must have completed its testing cycle. Floorings consisting of old tiles, marble-chip floor tiles or natural stone must be solid, well anchored and without any cracks. Any oil, wax, grease, etc. must be cleaned with a water and caustic soda solution or with another detergent already tested for such purposes, in order to thoroughly clean the surface in depth. Existing painting and lead sealing of the marble must be removed.

Porcelain stoneware - laying recommendations

In all cases, regardless of the type of substrate, it is very important to ensure that the surface is level, to prevent the formation of vacuums under the tiles that could weaken the laying, with particular attention to raised sections and the presence of foreign rigid bodies. Lay the tiles by following the indications of the designer, site manager and the laying specifications. Porcelain stoneware must be laid so that the adhesive ensures the perfect filling and adhesion over time, to prevent any deformation and guarantee the utmost reliability in all laying conditions. Select the most suitable adhesive by following the indications of the adhesive manufacturer. As a rule we recommend adhesives that ensure a good type C2 wettability (improved cementitious adhesive). The tiles can be laid, in the most common situations, with joints of minimum 2-3 mm, even if in certain situations (large surfaces, facings, deformable supports, etc.) larger joints are required along with expansion and distribution joints. We decline all responsibility linked to laying tiles without joints.

We recommend the use of a spatula with rounded teeth to guarantee a sufficient quantity of glue on the substrate and ensure that the tiles are soaked 100%. Use the double spreading technique to ensure that there are no gaps on the back of the tile or use an adhesive that ensures a perfect filling. During the laying make sure that the tiles follow the expansion joints on the substrate and the walls. Create division joints of about 1 cm for very large surfaces, dividing the area as follows: -on substrates subject to movements or bending allow for sections of about 9-12 m²; -on stable surfaces the joints can be about every 16 – 25 m². Lay tiles at about 5 mm from walls, columns, edges, corners, etc. During laying do not subject ceramic tiles to excessive stresses or violent knocks. The tiles can be cut without particular issues and after laying we recommend waiting for the adhesive to harden before making holes or cuts for accessories.
