It will be necessary to confirm the correct quantity needed for the project (including an extra 10% for cutting and fitting); confirm the ordered reference for correctness in what concerns the choice of pattern, quality, shade, and calibre of the tiles.

Before you start to apply adhesive cement to the tiles, it is advisable to open several boxes, taking alternatively tiles from all of them to verify uniformity of the shade.

No claims will be accepted by Gresart after the tiles have been settled.

The adhesive to be used depends on the type of tile to be glued, and the place of settling.

On porcelain tiles settling, Gresart recommends a gluing agent with mixed adhesives (cement and resin). For situations of extreme conditions, or in the case of heated floors, specific types of adhesive are recommended.

For all situations, we suggest that you always consult an adhesive manufacturer for further information.

In the case of floor tiles with a format of 40x40 cm, or bigger; and for all formats used as wall tiles, we recommend the double gluing technique (applying the adhesive cement both on the tile, and the support where it is going to be settled), thus minimizing slight curvature tendency in tiles of considerable length, and reducing the chances for lack of adhesive contact between the tile and the support.

The daily routine of cleaning our products is simple, it suffices to use a commercial brand detergent, and clean water. Commercial brand bleaches are also safe to use in cleaning our tiles.

Coloured spots (coffee, wine, wax, etc.) should be immediately removed with a moist cloth, otherwise it may be necessary to use a specific detergent to remove them latter.

In the event you should need a specific detergent, we recommend that you thoroughly inform yourself; and if necessary contact the detergent manufacturer before choosing one such product to ensure that you use the appropriate product for the job. You should previously test these products, ideally in a spare tile, or in a small area out of sight.

Never use abrasive materials, or products containing hydrofluoric acid.

Never scrub tiles with harsh tools, such as hard hair brushes, or steel scourer, in order to avoid the creation of visible scratches in the glazed surface.

There are 2 types of dimensions used to describe ceramic tiles according to EN 14411: 2015: Nominal Dimension and Manufacturing Dimension.

Nominal size (N) is an approximate dimension, used and recognized in several business areas, which designates the product´s size (for example. 60x60, 50x100, 33x33, etc...).

The manufacturing dimension (W) is the tile's dimension specified for production, with which all specified limits, and admissible tolerances, must be in accordance – calibers (for example: Length x Width x Thickness = (603x603x8,5mm; 338x338x7,2mm, etc).

Given the considerable retraction (6 to 7%) that the material endures during the production process, the manufacturing dimension, or caliber, is determined in the selection process, and referenced on the package where the products is conditioned.

Should you require more information about manufacturing dimensions, please request the product's technical information sheet, or contact our Commercial Department.

Note: The measurements referenced in the site are nominal dimensions (N).
