How is the settlement of the tile? What kind of mortar should I use?

The settlement must happen with the piece dry. Make sure to clean the grooves of the piece. Any type of prefabricated plaster of good quality may be used.

Settlement on a painted wall:
To work on a Painted wall you must perforate it before putting the product to adhere to the mortar in the wall.
Mortar for each type of setting:
AC1 –Internal setting
AC2 –External setting
AC3 –Hot settings (Barbecue grill, fireplace, wood stove). 
What is the space between pieces to keep when settling?

For 11x26 and 6x26 sizes we recommend a 7 to 10 mm spacing.

How long will it take to clean the grout once it is applied?

The grout takes 15 minutes to dry. It starts to harden after 2 ½ hours after preparing. These are: the minimum and maximum times for cleaning. Preferably, clean it immediately, that is,starting from 15minutes.

No grout is recommended on dark colors. 
How do I clean the Pierini tiles?

To clean the Natural tiles, use a cloth or a damptow before the external drying of the material applied when laying. NOTE: WE DO NOT RECOMMEND THE DARK GROUT IN THIS JACKET (NATURAL).To achieve a perfect cleaning, prepare a cleaning solution and rinse the tiles strongly. Soon afterwards, rinse with plenty of clean water. For cleaning of enameled tiles, follow the same procedure. WARNING: The permanence of the solution, especially when used in greater than recommended concentration, corrodes cement joints.

No grout is recommended on dark colors, such as Black, especially in the NATURAL product. You may use the Gray one instead.

You must not cover the inner part of the grill, fireplace, wood stove.

We do not recommend applying varnish, resin, any waterproofing agent on the piece, especially to the Natural.

What safety measures must one take with the NATURAL product?

Caring so the grout will not dry on the piece and make cleaning harder.

What is "shade variation"?

It is the change in color tone of a product by an intentionally, continuous, controlled and standardized way.

Intentional because it is no coincidence, it is not the result of factors beyond control,it isa deliberate and carefully planned and caused variation.

Continuous because it is not a succession of groups of different shades, it is not the change of tone between batches, it is rather a continuous variation of tone, such that any random sample of the product possesses in its interior every shade planned.

Controlled because it is not a random variation, it is the production of an ordered sequence of changes that must occur within specified limits.

Standardized because variations do not vary with time, they are always the same variations that should occur. A set of tones should be defined and standardized for each product.

Intensity of shade variation.
The Ceramic Tile Distributors Association in the USAadopts 4 classes of color shade variation. Our lines are classified following this system:
V1 – Uniform appearance. The differences between the pieces are insignificant.
V2 – Low variation. One can distinguish small variations between the pieces.
V3 – Moderate variation. Shade variation where the dominant color of a part is present, even slightly, in other pieces.
V4 – High variation. Variation where the color of a piece can be totally different from the other, with the harmonic set remaining.
