before proceeding with installation, the fitter is recommended to show the end customer an example of how the tiles will be installed (by placing them in accordance to the Spreading adhesive and installation: precautions

Light differences in tone are a typical characteristic of some ceramic products. As a general rule, the most suitable adhesive is found by taking the following factors into account:
Ceramiche Marca Corona recommends installation with slabs offset by 1/3 at the most and a grouting joint of at least 2.0 mm for single sizes and 2.0/3.0 mm for Type of support I Type and size of tile I Intended use (floors/walls - indoor/outdoor) I Climatic conditions during installation I Time needed to put tiling

• For outdoor installation, tiles must be installed with an open joint (at least 3.0 mm). For extra large tiles installed at a height of over 3 metres, some international standards set forth the necessity to install with a system featuring both adhesive

Cleaning during installation Spread the adhesive on the bed using a suitably toothed trowel.
In order to obtain the best results in terms of chromatic effect, pick tiles from different boxes. Exert sufficient pressure on the tiles to ensure wetting of at least 70% of the total tile surface.
During installation, the fitter must report any imperfections of the supporting surface (steps or small different in level between adjacent tiles, etc.) and ask for a written When installing in interior commercial environments or outdoors, it is of the utmost importance to spread adhesive both on the tile face and the support

and to check that materials and installation are as described above. Recommended grouts
During the time running between conclusion of installation work and delivery to the end customer, ceramic tiling must be:
• kept clean from cement, sand, mortar and any material that could cause staining and/or mechanical surface abrasion; It is important to use a grout that is suitable for the intended use of the tiling.
• protected against damage and soiling due to the work performed by other workers at the site (painters, electricians, woodworkers, etc.). Follow the indications of leading grout manufacturers.
