RECOMMENDATIONS RELATING TO INSTALLATION, MAINTENANCE AND
DEMOLITION OF CORSO ITALIA CERAMIC TILES
A. BEFORE INSTALLATION
Prior to installation, the installer, that is to say the technician who carries out the tiled surface and the first person who “sees” and
“handles” the ceramic tiles, must inform the final customer or foreman responsible for the works of any faults (quality, colour
shade...) in the ceramic tile.
Please consider that colour shading is an intrinsic characteristics of certain ceramic products.
Corso Italia does not recommend zero joint or close joint installation and suggest to carry out a straightforward installation
pattern with tiles staggered up to a maximum of approximately 33% of its length:
The width of grout lines must be calculated, during project-planning, according to the following criteria:
1) Type of substrate:
2) Destination of use of the material (indoor/outdoor flooring, indoor/outdoor wall cladding);
3) Any standard and/or regulation in force in the country where the tiles shall be installed.
B. DURING INSTALLATION
Corso Italia recommends to collect the tiles from different boxes in order to obtain the best chromatic effect.
When planning necessary cuts, never mark the tiles using pencils and/or indelible felt-tip pens.
During installation, the installer must point out the presence of any imperfections on the ceramic tiles (presence of steps or
uneven levels between adjacent tiles etc...) and the installer must ask for official written authorisation to proceed with the work
from the final customer or from the foreman responsible for the works.
The final customer must also provide an assurance that the lighting and micro-climatic conditions at the workplace are sufficiently
good to allow the installer to lay the tiles correctly, and the installer must check the ceramic materials and the installation
procedure, as stated above.
Between the installation and the consignment to the final customer, the ceramic tiling must:
Be kept clean and free from any cement, sand or other dirt residue which can cause stains and/or mechanical abrasion to
the surface;
Be protected from any damage caused by the presence of other operators (painters, electricians, carpenters, etc.).
WARNING:
ONCE THE CERAMIC TILES HAVE BEEN INSTALLED, CORSO ITALIA:
DO NOT ACCEPT RESPONSIBILITY FOR COMPLAINTS RELATING TO MANIFEST FAULTS OF SHADE AND QUALITY;
WILL NOT BE LIABLE FOR THE QUALITY OF THE TILED SURFACE BUT ONLY FOR THE QUALITY CHARACTERISTICS OF THE
SUPPLIED MATERIAL.
ON COMPLETION OF THE INSTALLATION IT IS ADVISABLE TO KEEP SOME SPARE TILES ASIDE, SHOULD ANY TILES NEED
REPLACING OR AS A REPRESENTATIVE SAMPLE OF THE MATERIAL IN CASE OF COMPLAINTS.
C. TESTING OF THE TILED SURFACE
The testing of the tiled surface must be done by the final customer in the presence of the installer or the foreman responsible for
the works and consists of a visual examination (naked eye and/or with glasses if normally worn) of the surface from a distance of
1.5 meters.
An “effect” which is only visible close-up or with grazing light, perhaps with the use of a magnifying glass cannot be considered a
“defect”.
An “effect” becomes a “defect” only when clearly visible under the conditions stated above.
D. ELIMINATING EXCESS GROUT
To correctly and easily eliminate excess grout, follow the instructions given by the grout manufacturer. In general, proceed as
follows:
