In this section you will find the most frequently asked questions about porcelain stoneware and Kerlite
WHAT IS KERLITE?
"Kerlite" is laminated stoneware obtained by means of an extremely innovative production system, which is the outcome of the latest technology.
It is produced in whole slabs of size up to 300x100 cm without using dies. Kerlite is pressed at a force of 27,000 tons.
A fully automated cutting line allows different sizes to be cut.

HOW IS KERLITE LAMINATED PORCELAIN PRODUCED?
An innovative interpretation of the production process has lead to development of machinery that breaks new grounds. The production system is characterised by a high level of automation and the process takes place with a considerable reduction of dust, noise and emissions. Kerlite laminated stoneware is made using the same "families" of raw materials that are used for conventional porcelain stoneware tiles: clay, kaolin and feldspar. However for the production process, innovative and patented pressing, decorating and firing systems are employed.
The production process is highly automated. Each stage is controlled by process supervisors; semi-finished and finished products are handled by laser guided vehicles. All technology employed does not create mud and waste water that needs to the treated. The consumption of energy - basically electric - is particularly low.
These systems reduce the impact on the environment, thanks to the extremely low emissions of CO2 and other harmful gases and to reduction of dust that is let out into the environment.
IS KERLITE EASY TO PROCESS?
A particular feature of Kerlite is that it is extremely easy to cut, shape and drill using automatic machines and tools for processing glass and porcelain stoneware.
Kerlite slabs have an original thickness of only 3,5, 5,5 and 6,5 mm; this makes them flexible, light and extremely easy to handle.
The minimum thickness is the innovative feature, which makes the product suitable for a variety of different applications.
There are 14 standard sizes:
CAN YOU SEND ME AN INSTRUCTION HANDBOOK FOR INSTALLATION OF KERLITE?
The Kerlite technical manual, containing all the advice and instructions for installing and cutting Kerlite laminated stoneware, can be downloaded in PDF format here.
CAN I INSTALL KERLITE PLUS ON AN EXISTING WOODEN FLOOR?
Installation on an existing wooden floor is possible. However, make sure that the existing floor is firmly secured in place and perfectly flat. Sandpaper the surface of the parquet until it is rough.
CAN I INSTALL KERLITE PLUS ON AN EXISTING MARBLE FLOOR?
As far as old ceramic, cotto, stone, marble or PVC floors are concerned, make sure they are sound and firmly fixed. The existing floor must be dry, stable, sound, perfectly flat and clean, which means that there must be no brittle fragments compromising adhesion of Kerlite Plus.
Flatness checking should be performed using a screed with a length of at least 2 metres. Place the screed on the old floor in all directions and, if necessary, compensate for any differences in level.
Eliminate any residues of oil, grease or wax by washing with a solution of water and caustic soda followed by thorough rinsing. If chemical cleaning is not possible, adopt mechanical abrasion techniques.
Of course! The high technical performance of Kerlite, in particular its resistance and cleanability, make it ideal for any environment that must be hygienic and clean.
In particular, the exclusives 100x300 cm and 120x260 cm sizes reduces grouting to a minimum to guarantee the utmost hygiene.
IS KERLITE SUITABLE AS KITCHEN TOP MATERIAL?
Of course. Kerlite is very versatile and is recommended for kitchen tops.
Cutting, drilling and shaping of slabs is particularly simple, which makes Kerlite suitable for kitchen tops. The high firing temperature of the slabs make Kerlite resistant to heat, which means that it resists scorching hot pots and pans.
Kerlite does not absorb liquid and odours and does not hold back dirt.
Porcelain stoneware is a hard and compact ceramic material that is coloured and non-porous. "Stoneware" means that the ceramic body of the tile is extremely vitrified and therefore compact and featuring a high mechanical strength.
This ceramic body is obtained starting from a mixture of clay, sand and other natural substances. After being suitably prepared, these mixtures are fired at a high temperature (1000 – 1300 C°).
One of the most outstanding features of porcelain stoneware is its extremely high resistance to abrasion, in other words the resistance that the surface has with regards to the movement of bodies, surfaces or materials that come into contact with it.
IS PORCELAIN STONEWARE SUITABLE FOR INSTALLATION ON HEATED FLOORS?
All Cotto d’Este porcelain stoneware floors, by virtue of their great heat conductivity, which is equal to 1.3 Watt/m °K or 1.1 Kcal/m h °C (refer to EN 12524:2001 standard), are highly recommended for installation on heated floors.
Care and Cleaning
WHICH DETERGENTS SHOULD ONE USE FOR CLEANING AFTER INSTALLATION?
“Post-installation” cleaning helps remove residues of joint grouts, cement and lime. This operation is mandatory after installation both for glazed and unglazed tiles. Never clean tiles that are too hot (e.g. exposed to sunlight during hot summer months) since the reaction of aggressive chemicals may become harsher. In the summer, proceed with the operation during the coolest period of the day.
