Recommended adhesives

The use of a suitable adhesive is essential for installation. For the installation of ceramic tile, follow the indications of leading adhesive manufacturers.

As a general rule, the most suitable adhesive is found by taking the following factors into account:

Type of support — Type and size of tile — Intended use (floors/walls - indoor/outdoor) — Climatic conditions during installation — Time needed to put tiling in

conditions of use.

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 and

mechanical hooks to be chosen based on the weight of the tile, on the height of the paving and on work site conditions.

Spreading adhesive and installation: precautions

Spread the adhesive on the bed using a suitably toothed trowel.

Exert sufficient pressure on the tiles to ensure wetting of at least 70% of the total tile surface.

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 (double-

spreading) so as to avoid gaps between the ceramic tile and the support.

Recommended grouts

It is important to use a grout that is suitable for the intended use of the tiling.

Follow the indications of leading grout manufacturers.

Warning:

Ceramiche Marca Corona may not be held liable for defective flooring caused by improper laying. We suggest keeping some spare tiles to use for any repairs or

product quality checks if required.

Cleaning after installation

Washing after installation is of essential importance for all subsequent maintenance operations. By performing proper cleaning a

fter installation, you will remove installation

residues and standard work site dirt, such as for instance: mortar, adhesive, paint, work site dirt of different types. After grout has dried, clean with a suitable detergent and

always following the instructions for use and dilution provided by the manufacturer on the pack.

a) If you are using cement-based grout, Ceramiche Marca Corona recommends the use of FILA DETERDEK (or similar acid buffer detergents, with the exception of

products containing hydrofluoric acid) since this product neither emits harmful fumes nor has an aggressive action on grout.

Apply as follows:

— Use FILA DETERDEK diluted in a 1:5 solution (1 litres of FILA DETERDEK in 5 litres of preferably warm water; yield: 1 litre/40 m

— Sweep the floor with care and spread the diluted acid solution using a mop or rough cloth for residential environments or using a motorised brush with white or green

discs (depending on needs) for large surfaces.

— Let the solution work for a few minutes, depending on how deep the dirt is.

— Use a green or white Scotch-Brite abrasive sponge or a scrubbing brush with nylon bristles for structured surfaces, or a motorised brush with white or green discs and a

liquid aspirator for large surfaces.

— Soak up any residues with cloths or a liquid aspirator.

— Rinse with plenty of lukewarm or warm water and repeat this operation several times until all stains or residues in the gaps of structured tiles have been removed.

Should you still notice areas that are not perfectly clean, repeat washing but increase the concentration of acid. Refer also to the specific information provided below.

Warning:

this operation may be aggressive on materials and components placed near the tiling, for instance thresholds, marble window sills, metal doors and windows, decorations,

etc. It is highly recommended to protect these surfaces before cleaning.

b) If you are using epoxy-based grout, it is essential to scrupulously follow the instructions provided by the detergent manufacturer since, after hardening, this type of

grout is extremely difficult to remove. In this case, Ceramiche Marca Corona recommended you to add 10% of alcohol to the washing water or, as an alternative, to use

undiluted FILA CR10 alkaline detergent (or a similar product). FILA CR10 must be used undiluted and must be left to work for about 30 minutes. Then rub the surface with

a mildly abrasive brush and rinse with plenty of water.

Specific information:

c) After installing products with a honed, polished or metal-effect finish, the acid-based detergent you intend to use must be tested on a small area before actual use.

d) Avoid using abrasive products on decorations and special inserts as they could damage the surfaces.

After grouting coloured and/or anodised aluminium profiles, remove any residues immediately using a sponge and a mild detergent to prevent the grout hardening.

e) After installing structured or non-slip products, cleaning after installation can be repeated several times, using a higher concentration of detergent and more

abrasive brushes, since this type of product tends to withhold more grout/dirt. Correct cleaning will allow you to resume the right appearance and obtain the best

non-slip performance.

f) As far as products with a natural/matt finish are concerned, Marca Corona does not recommend priming/film-forming products since they are not necessary.

Furthermore, too much priming product, if not removed correctly, could withhold dirt more easily.

g) As far as used floors are concerned, before treating the floor with an acid product, remove any greasy or similar substances with an alkaline detergent, such as FILA

PS87 PRO.

Reference standards:

Final testing of the tiled surface

Final testing must be performed by the end customer, at the presence of the fitter and project engineer. It consists of a visual check (with glasses, if these are worn)

of the surface, at a distance of 1 metre. Any effects evident only in sidelight or with the aid of magnifying lenses or other optical instruments may not be considered

as defects. Durability of a tile surfaces strictly relates to the manner it which it is taken care of; the end customer has an important role in keeping the tile surface in

good condition, both aesthetically and technically, over time.

Some precautions, which also depend on common sense as well as on knowledge of the materials installed, must be observed.

Routine cleaning

If the cleaning rules covered thus far were followed after the installation, routine maintenance, i.e. everyday cleaning to remove dirt from traffic and general use of the

tiled surface, is not a problem.

CORRECT CLEANING is performed using a cloth or sponge moistened in a diluted solution of common neutral detergent for tiles, following the instructions for use

and dilution provided by the manufacturer of the product.

When the surface has a different appearance from the original one, “degrease” using FILA PS87 PRO an alkaline detergent and then rinse thoroughly.

In particular conditions of use (relating to the type of detergent used and/or on staining agents that commonly come into contact with ceramic materials) and

environmental conditions (material installed outdoors), instead of degreasing, it is preferably to perform “descaling” with FILA DETERDEK PRO an acid detergent

followed by thorough rinsing.

Ceramiche Marca Corona recommends:

a) Daily:

— Remove dust with special brooms, woollen cloths or a vacuum cleaner.

— Wash with FILACLEANER PRO (low-residue neutral detergent) diluted in a 1:200 solution (a coffee cup of product in 5 litres of water) and use a cloth to be rinsed

often in the solution.

Warning

Irrespective of the washing method adopted, if the surfaces features cloth marks, wash with clean water, rinse often, wring the cloth thoroughly between one rinse

and the other. Never use too much detergent in water, unless the floor is very dirty and must be rinsed after washing.

b) Periodically:

Degrease using FILA PS87 PRO diluted in water (preferably warm as this increases its effectiveness) in a 1:20 solution. If descaling is necessary, use FILA DETERDEK

PRO diluted in water (preferably warm as this increases its effectiveness) in a 1:20 solution, followed by thorough rinsing.

Warning

If the surfaces are not perfectly clean, repeat degreasing and/or discaling using a more concentrated solution.

The person in charge of these operations must always perform a preliminary test on a small area of material.

For large surfaces, preferably use a washer-dryer machine and a neutral detergent, such as FILACLEANER PRO in a solution ranging from 1:100 to 1:200, as requested.

During cleaning, it is advisable to reduce the use of strongly abrasive cleaning methods to an absolute minimum, especially on tiles with a smooth texture (glossy and/

or satin finish), as they can be more vulnerable to scratches and loss of brilliance.

Some types of dirt (sand, etc.) increase the abrasive effect of pedestrian traffic on the surface; therefore, it is recommended to keep the floor as clean as possible in

order to prevent the build-up of this kind of dirt taken if from outside. It is recommend to use doormats designed to retain dirt and damp (fixed or mobile doormats

depending on the destination of use of the area) and to position them to so as to cover the entire length of the entrance

Extra-duty maintenance

In the event of dirt resistant to routine cleaning, use a suitable detergent for the particular kind of dirt (Table below)
