Once the project has been completed, it’s necessary to buy the chosen tiles. At this stage it’s important to follow a number of tips, which allow the purchaser to order the right amount and to check the correctness of the supply.
How many tiles to order?
To order the correct amount, it is necessary:
to know the extension of the surface to be tiled and
to have already selected the laying technique and laying design.
Considering thateven a top quality supply may contain some defective pieces, andsome tiles will probably have to be cut or perforated during laying, it is advisable to order 10% more tiles than the amount necessary for the surface to be tiled.
How to ensure an accurate supply?
In order to be able to check the supply, the order must include all identifying product data and the quality class.
The supply is characterized by two important factors: tone and working size.
The tone indicates the colour shade of the single batches of tiles.
In industrial production, there may be small variations in colour; therefore, the tiles are controlled in the sorting phase and grouped in homogeneous classes according to colour tonality.
The working size corresponds to the manufacturing size, and just like tone, may vary in the production process. During the sorting phase, the tiles are grouped in lots with the same dimensions. Tone and working size are usually written on the packaging and in the shipping and accounting documents relating to the supply.
These two parameters should be carefully checked in order to carry out successful laying: tiles traceable to the same catalogue item, but of different tone and working size, should be considered as different products, and thus not suitable for tiling the same surface.
