Before cleaning an installed floor with an acid base product it is strongly suggested to pour water on the surface in order to wet the grout joint and protect

them from the corrosive action of the acid. Otherwise it may happen that the acid solution included in the cleaning product could erode the grout.

In case the first cleaning is made after the floor has been used, it is necessary to remove the dirt that could be found on the floor using alkaline based

product, and then proceed with the post laying cleaning. After this process it is necessary to profusely pour water on the floor and, as a final step, remove

as much dirty water as possible.

The cleaning after laying needs to be done once the grout in the joint is fully dry (48 to 72 hours), properly following the indication of the manufacturer of

the cleaning product used.

The cleaning after laying made with acid based products needs to be done only once and has the advantage of maintaining an uniformity in the colour

tone of the entire floor.

ROUTINE MAINTENANCE

You are recommended to use ordinary neutral detergent diluted in water. Avoid using acid or alkaline products, waxes and/or impregnants.

During ordinary cleaning it is recommended to use extremely abrasive items (such as scourers and iron or steel sponges) as little as possible.

This recommendation must be adhered to rigorously in the case of tiles with a glossy surface finishing as they are more susceptible to the risk of scuffs,

scratches and loss of shine, etc.

In the event of heavy dirt or particularly textured surfaces, use an alkaline detergent and rinse after washing. For large surfaces, the use of a floor washing

machine is recommended. During every-day cleaning procedures, it is necessary to remember that certain types of dirt (dust, sand) increase the abrasive

effect of foot-traffic. Therefore we recommend that you avoid bringing in this type of dirt, which comes in from the outside, by placing a door-mat at the

entrance.

EXTRAORDINARY MAINTENANCE

In the event of dirt resistant to the ordinary cleaning, use a suitable detergent for that particular kind of dirt.

METALLIZED FLOOR AND WALL TILES

For the cleaning and maintenance of the tiles with iridescent metal effect surface it is strictly recommended not to use acid or alkaline detergents.

Please use exclusively products with neutral PH.

In any case please test each cleaning product in advance, if possible on a piece of the material not laid and avoid to leave the detergent on the tiles for

more than 10-15 minutes. Always rinse heavily with water after cleaning.

RECOMMENDATIONS

247

Last but not least, please remember never to use stain remover such as anti-rust products or sprays, because they contain hydro-fluoric acid: this would

case irreparable damage since no floor tile in the world, whether produced by us or others, withstands this acid.

The following are the most suitable cleaning products for the various types of dirt.

WARNING

The cleaning characteristics of the materials may vary significantly depending on the laying method, conditions of use, type of surface and environment.

Generally speaking, the higher the non-slip characteristics of the tiles, the more difficult they are to clean.

The maintenance and cleaning operator should always test each cleaning method empirically in advance (if possible on a piece of the material not laid).

In the case of particularly heavy use, incorrect laying or inappropriate cleaning, Serenissima declines all responsibility for the

effectiveness of cleaning and maintenance operations.

Serenissima can under no circumstances be held responsible for events, damage or defects caused by incorrect laying, negligent cleaning and maintenance

or the use of inappropriate materials and adhesives.

TREATMENT OF HONED AND POLISHED PRODUCTS

Polish and lap are process that foresee the removal and polishing of the superficial part of the glaze or of the tile body.

In all glazed floor tiles available in the market, this process, even with vitreous or with very low absorption materials, can involve the opening of superficial

micro porosity which, in contact with particular kind of dirtiness, can be hard to clean or present haloes hardly removable.

Serenissima recommends, after the washing after the laying, that must be made using an acid cleaner, to effect an antistain protection with certified

products, in order to prevent that the material can absorb the stains maintaining unchanged the aesthetic and technical features of glazed porcelain.

We remind you that any treatement the producer maker before laying, will be completely removed by washing at acid base that must be done after the

laying and therefore no efficace anti stain can be granted.

To Serenissima’s customer it is requested to inform, before the delivery, layers and/or consignees of our products with the advices, warnings and

recommendations inside this book.

Serenissima declines all responsibility for the lack of these information which can cause problems during or after the laying of the product.
