Frequently asked questions

What is porcelain stoneware?

Porcelain stoneware is a mixture of raw materials similar to those used for vitreous china (used for sanitary and tableware manufacturing). It is therefore a material almost completely vitrified, completely insensitive and with high mechanical characteristics. The adjective porcelain, which emphasizes the refined elegance that characterizes it, derives from the use of kaolin, a white clay that is also used for the production of porcelain.
Precious clays and feldspar are subjected to a firing process at extremely high temperatures and are transformed into stoneware tiles with characteristics of anti-elivity, resistance to shocks, scratches and chemical attacks.
The porcelain tiles are therefore extremely resistant, hygienic and with elegant aesthetic.

Can Keradom products be used also for the outdoor?

Yes, Keradom products’ are 100% made in Italy using Porcelain Stoneware, therefore given the exceptional characteristics, can be used to realize sidewalks, driveways, driveways, swimming pools and so on, without any problem of duration. The Porcelain stoneware is in fact a product resistant to all atmospheric agents.

It does not burn and does not contain plastic, so it is sustainable.

Are Keradom collections sustainable?

Keradom porcelain stoneware is a sustainable product because it is made with closed cycle technologies that recover and reuse energy, production waste, processing water and raw materials contained in it. This allows Keradom to produce tiles in an environmentally sustainable way, which means: limiting the extraction of new raw materials – with a contribution to the natural recovery of quarries -, reducing the use of water, optimizing energy consumption and waste management.

How can I clean Keradom’s stoneware?

To effectively clean Keradom porcelain stoneware it is important to distinct two stages: after laying and daily maintenance. First of all, it is mandatory to have a proper after-lay washing to the tiles. This is necessary to eliminate residues of dirt of various nature (mortar, glue, paint) produced in the construction site. Precisely, we recommend to perform this stage of the cleaning by using buffered acids in order to dissolve and remove all the dirt residues. It is also important to rinse well until the washing water is clear. For what concern the daily cleaning, we suggest to do it using a floor cloth and a mixture of hot water and neutral detergent easily available on the market. We recommend that you do not use wax or rinse aid or abrasive tools such as metal spangles and hard brushes. We also do not recommend the use of abrasive detergents on glossy and/or polished surfaces; this type of tools can be used only on matt materials, after verification on a small portion of tiles. For particular stains or in the presence of very tenacious dirt we suggest the use of specific detergents, diluted in water according to the proportions indicated by the manufacturer, to be left to react for the period of time always indicated by the manufacturer.

Does three-dimensional structure make cleaning more complicated?

No, thanks to the common characteristics of porcelain stoneware and the attention in the study and development of Keradom products, cleaning three-dimensional coatings has never been so simple; Simply follow the recommended cleaning instructions and you will get the removal of stains and dirt. Unlike common three-dimensional natural stone coverings, chalk and polystyrene coverings, dirt does not cling to the surface and cleaning is simple and effective even at the deepest points of the tile.

What is the correct escape size?

Before laying in the yard, the tiler must check the tonality, size and choice of the material, while for the laying the tiler must always use tiles of multiple boxes to obtain the ideal mix of colors.
The tiler must also check before laying in the product any obvious defects that would not be covered by warranty if reported after laying.
The tiler must use adhesives suitable for the various types of use and follow the directions on the package.
The size of the joints may vary depending on the size of the tiles, in order to keep the preferred laying modules.
Keradom recommends a minimum putty of 2-3 mm for Keradom products both interlocking and not.
During the laying of rectangular tiles it is recommended not to stagger the tiles by more than 6-10 cm (2″ -4″).

Do the wall coverings need to be plastered?

Yes, Keradom strongly recommends the stucco of all porcelain stoneware wall coverings.
Grouting a wall covered with keradom products, is safer. In fact it has a better technical result – it is more stable and less flexible – and hygienic – dirt does not settle between one tile and another. In addition, the results.
The correct choice of the stucco colour (in combination with the coating tone) allows to visually lose the modularity of the tile laying in the wall. You get the effect “loosing piece”, which in Keradom interlocking products is enhanced; the effect will be that of a single-piece mosaic, but with the simplicity of laying ceramic products.

What criteria to use for choosing the right skirting board?

The choice of the correct baseboard is subjective. Keradom recommends however to choose a baseboard in combination with the tone and effect of the floor purchased, in order to achieve a visual effect of continuity on the wall.
The Keradom catalogue also proposes decorative solutions with geometric and colour effects (Mystica, a project aimed at DIY painting) for those who see an element of detachment and character in the skirting board.
