Installation suggestion

Below some recommendations relating to installation of Ceramiche Marca Corona tiles

BEFORE INSTALLATION


As the professional figure responsible for creating the tiling and the first to “see” and “handle” the tiles, the person laying the tiles must:
• Notify the client and designer of any obvious defects (quality, tone, etc.) in the tiles;
• Follow a tiling plan which specifies a particular installation technique (closed, minimal or open joint, laying in parallel or diagonal, continuous or staggered joints, etc.); before proceeding with installation, it is recommended that the installer shows the final customer a representative sample of the tiles to be installed (by laying them down in the intended installation pattern without using any grout) and asks for verbal, or, better still, written approval.
The mellow patina giving the tile surface different hues is a characteristic feature of some ceramic products.
Ceramiche Marca Corona recommends an installation pattern offsetting the planks at the most of the 1/3 and leave at least joints of at 2,0mm in width when laying a single sized and obligatory 2,0/3,0mm when laying a combination of the both sizes.
• For outdoor floor recommends open joint installation (at least 3,0mm).


DURING INSTALLATION


Before starting the installation process, make sure the laying surface is well cured, flat and completely clean.
To obtain the best chromatic effects, alternate tiles from different boxes.
During installation, the installer must point out the presence of any imperfections on the tiled floor (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, CERAMICHE MARCA CORONA:
• 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 SOME TILES NEED TO BE REPLACED OR AS A REPRESENTATIVE
SAMPLE OF THE MATERIAL IN CASE OF COMPLAINTS.


Hithick 20mm. Warnings for laying on raised floors.


WIND AND BREAKAGE WARNING


Outdoor pavings installed unglued above the ground level are subject to the action of the wind, with the risk, in some cases, of becoming airborne. The manufacturer recommends to require the assistance of a qualified professional in order to check the suitability of the installation system above the ground adopted, in accordance with the local laws and regulations and the conditions of use. Failure to do so could result in serious injury or property damage. A ceramic slab installed on a raised pedestal system may fracture on impact if a heavy object is dropped onto it from a height, with a risk of injury to anyone standing or walking on such slab. Failure to adhere to the manufacturer’s instructions for installation of slabs on raised pedestal systems may result in serious injury. For further information and recommendations concerning the installation systems please refer to Ceramiche Marca Corona website or to the 20mm catalogue “HiThick”.


INSTRUCTIONS FOR PROJECT ENGINEERS AND CUSTOMERS


If the application of the 20 mm slabs foresees the ceramic product used in structural installations, the project engineer and/or customer must carefully assess the project requirements with regard to the technical specifications of the slabs. To prevent the risk of damage or injury, the manufacturer recommends:
• With regard to a raised floor installation a ceramic slab may fracture on impact if a heavy object falls on it from any significant height. Therefore the manufacturer recommends to check the specific intended use before starting the installation and to follow table for raised installation provided below. In certain conditions, reinforcing must
be applied on the back of the slabs (Fiber-Mesh Plus) supplied and applied by the manufacturer;
• With reference to any dry installation system of flooring above the ground level, the manufacturer recommends to comply with local regulations and conditions of use with regard to wind-load, loadbearing, seismic events, etc.
Failure to comply with these recommendations may lead to improper use of the product and could cause serious damage or injury.

Recommended adhesives


The use of an appropriate adhesive is essential for a correct installation. For the installation of ceramic tiles You should follow the laying instructions provided by leading adhesives manufacturers. You should choose the most suitable adhesive on the basis of the following factors:
Type of bed I Type and size of tile I Use of tiled surface (floor/wall; indoor/outdoor) I Weather conditions at the time of laying I waiting time before the ceramic surface can be used.

To discover the most appropriate adhesives for your project, please read the PDF document below

Spreading the adhesives and laying the tiles: tips


Spread the adhesive on the bed using a suitably toothed spatula.
Press down well on the tiles to ensure wetting of at least 70\% of the total surface.
When laying tiles in commercial interiors or outdoors, it is vital to apply the adhesive using the double spreading technique to avoid empty spaces in the ceramic tile-bed interface.

It is important to use a grout appropriate for the use to which the ceramic surface will be put.
You should follow the instructions provided by leading grout manufacturers.


Use and recommended grouts according to european standards EN 13888:

  • residential interiors: improved cementitious mortars for joints (Class CG2 - EN 13888)
  • damp interiors (bathrooms, showers, swimming pools, etc.) and outdoors: improved cementitious mortars for joints with low water absorption (Class CG2 W - EN 13888) obtained with the addition of a suitable liquid additive;
  • commercial premises: improved cementitious mortars for joints with high resistance to abrasion (Class CG2 Ar - EN 13888) obtained with the addition of a suitable liquid additive;
  • premises requiring total hygiene and resistance to chemical agents (kitchen work surfaces, food industry, hospitals, supermarkets, etc.): epoxy mortars (Class RG - EN 13888).

Eliminating excess grout

To correctly and easily eliminate excess grout, follow the instructions given by the grout manufacturer. In general, proceed as follows:

  • cementitious grouts: when the grout becomes opaque (normally after 10-20 minutes), clean with a hard cellulose sponge using movements on a diagonal to the joints. It is important to respect the drying time to avoid removing the grout from the joints.
  • epoxy grouts: when the mixture is still fresh, wet the surface with plenty of water, emulsifying with a Scotch-Brite® pad, paying attention not to empty the joints. The residual grout liquid can be removed with a hard cellulose sponge (to be replaced when excessively soaked with resin).
    It is vital to remove epoxy grout rapidly before it starts hardening as it is extremely difficult to remove subsequently. If the epoxy grout has started to harden, try adding 10\% alcohol to the washing water.

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 meter.
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.


CLEANING AFTER INSTALLATION


The cleaning of the entire flooring after installation is of vital importance for all subsequent maintenance procedures.
Cleaning eliminates residues as well as dirt such as cement, glue, paint and other kinds of dirt, etc. Once the grout has aged properly, the cleaning using a suitable detergent can begin, but must be carried out in strict accordance of the instructions of use and dilution percentages stated by the manufacturer of the detergent.


a) Ceramiche Marca Corona recommends FILA DETERDEK (or any other equivalent buffered non organic acid cleaner, with the exclusion of hydrofluoric acid) for the removal of cementitious grout residues. Follow instructions below:
• Use FILA DETERDEK diluted 1:5 (1 litre FILA DETERDEK in 5 litres of hot water, result: 1litre/40Sq meter);
• Sweep the floor accurately, and wet the grout joints with water to protect them from the corrosive action of the acid;
• Sweep the floor and then spread the diluted acid solution evenly using a scrubbing-brush, a mop or a rough cloth for residential floors, while larger surfaces should be cleaned using a single-brush equipped with white or green buffering disks (depending on the necessity);
• Leave the detergent to act for a few minutes depending on the amount and type of dirt;
• Use an abrasive sponge such as a white or green scotch-brite or a scrubbing-brush with nylon bristles for textured surfaces, or, in the case of large surfaces with a singlebrush equipped with green disks and liquid suction capability;
• Collect any residue using a cloth or the liquid suction equipment;
• Rinse with lukeworm or hot water repeating the operation more than once until complete elimination of any rim or dirt residue present on the cavities of textured tiles.


Should some areas of the floor remain dirty, repeat the acid washing with a higher concentration of cleaner.

WARNING
This procedure can be aggressive towards materials and objects placed close to the tiled surface; for example doors and window sills made of marble, metallic shutters, decors, etc.; it is advisable to protect these materials before proceeding with the cleaning.

For floor and wall tiles with metal profiles, please read the PDF below with useful instructions for laying and cleaning

b) For the removal of epoxy grout residues it is absolutely necessary to follow carefully the indication of the cleaner manufacturer, as this can be particularly challenging. Marca Corona recommends warm water and 10\% of alcohol or, as an alternative, an alkaline cleaner like FILA PS/87 (or equivalent). PS/87 should be applied not diluted on the floor, and let act for about 30 minutes. Then scrub the floor with an abrasive brush and rinse with abundant water.


SPECIFIC INSTRUCTIONS:
c) For Polished, Semi-Polished and Metallic porcelain any acid cleaner should be tested on a small area, before cleaning the entire floor.
d) Textured porcelain, or products with high anti-slippery characteristics may be cleaned several times, utilizing increasing concentrations of detergent and a more abrasive brush, as this type of products may retain more dirt and grout residues. Proper cleaning will restore the original beauty of the product and its anti-slippery characteristics.
e) Matte finish products (non-polished) should not be sealed. If not properly removed, an excess of sealer could actually cause the floor to retain dirt faster.
f) For used floors, before performing any acid cleaning, it is important to remove all the organic residues (grease and similar) with an alkaline detergent, like FILA PS/87 or equivalent.
