POLISHING, RESTORATION AND MAINTENANCE
- What is Terrazzo alla Veneziana?
Terrazzo alla Veneziana is a very particular type of flooring. It is different from any other type of floor on the market not only because of its sheer esthetic value, but also because of a technical feature: the Terrazzo alla Veneziana is completely created on the spot. All the materials that make up the Terrazzo (concrete, coloring oxides, granulated marble) arrive to the building site separately and at their natural state. Nothing is ready-made or pre-worked. Each and every phase of the work – from the base preparation to the final waxing treatment – is carried out on the spot using specific materials, equipment and working techniques.
- How can I get a Terrazzo alla Veneziana?
Before the final confirmation it is necessary to make sure that no hindering factor may cause difficulties during the execution of the work or in time lead to the appearance of defects (even serious ones) of the floor. It is necessary to have an unloading area as near to the building as possible and as big as to have space enough to prepare the materials for the installation of the Terrazzo. The materials and equipment needed to install the floor will be transported from our premises to the building site with small sized trucks. Should the work be carried out in upper floors, a winch or lifter will have to be installed provided that it is possible to do so. When a crane is present at the building site, its use will have to be agreed with its owner company: the hence deriving costs will be borne by the customer.
- What does the building site need??
Materials, labour, and any other costs for the installation of the floor are on our charge and included in the agreed price. However, costs deriving from water and energy consumption are excluded. In particular, the customer will be responsible for the disposal of the sludge deriving from the sanding and polishing phase. It is worth remembering that this type of sludge is not toxic (it is made up of marble dust, inerted concrete and water) and therefore their presence on the building site does not constitute a danger neither for people, nor for the environment. Just store the sludge in special bags in a dedicated space; after a short period of time the sludge will have compacted and will be ready for disposal. Should the working site be unfit for this solution, our company has the means to provide for sludge collection and disposal. The costs of such operations are not considered part of the agreed price.
- How can I protect the floor during the work?
It is best to avoid stepping on the floor foundation during its curing period. This may compromise the foundation integrity and damage the surface, thus hindering a good anchoring of the next layer, i.e. the layer of the Terrazzo. Once the floor is installed it is advisable to protect its surface until all the other works on the building site are over. Geotextile fabrics (nonwoven fabrics) and any other material that allow a correct transpiration of the Terrazzo can be used to protect the floor. Therefore, it is strictly forbidden to use nylon or other film types that would cause irreparable damages to the floor because of the condensation. Geotextile fabrics can be easily found by construction materials retailers.
- What if the floor has imperfections?
The Terrazzo alla Veneziana is a handcraft product where the handwork is by far more important than the mechanical work. This may cause imperfections which may require restoration if these imperfections significantly compromise the floor. In order to avoid unpleasant misunderstandings after the completion of the floor, keep in mind that the Terrazzo alla Veneziana is a marble grit and concrete conglomerate. For this reason its final look cannot be perfectly homogeneous like a marble or granite sheet: as a matter of fact, the typical polishing of the Terrazzo is slightly amber, far from the so-called mirror polishing of other types of flooring. On the finished surface of the Terrazzo it is normal to find small holes. Despite the accuracy in choosing and laying the materials, cracks might appear on the surface even after many years. Anyway, thanks to particular synthetic resins nowadays available on the market, it is always possible to carry out interventions to restore the original state of the Terrazzo even over the years. The sanding technique of the Terrazzo produces gentle undulations on the surface. However, the Terrazzo has an intrinsic tendency to raise near the edges due to the normal concrete binder shrinkage.
- What kind of maintenance does the floor need?
The Terrazzo alla Veneziana is a type of flooring renowned for its stability and easy maintenance. Once the finishing works are complete – paintings, windows and doors mounting, etc. – opacity halos may appear on the Terrazzo due to dust deposits on the solid wax laid after the final polishing. To restore the Terrazzo and its best look just remove the dust with a wet cloth and then polish it with a polishing machine. Over time it is advisable to repeat the waxing at least in the areas exposed to wear. Firstly, use a wet cloth, then lay some liquid wax with the same cloth and remove it with a polishing machine. A particularly bright effect can be achieved by applying fine steel wool to the brushes of the polishing machine, thus ensuring the complete removal of the wax in excess on the surface.
- Which products can I use to clean the floor?
We recommend not to clean the floor too often, especially with inadequate detergents. Aggressive products such as ammonia, bleach, hydrochloric-acid based solutions may corrode the surface of the Terrazzo and a new polishing may be necessary. It is therefore recommended to use neutral and diluted detergents.
- What should I do in case of stains on the floor?
Acid substances such wine, beverages, fruits, vegetables and detergents produce an opaque halo limited to the extension of the stain itself. In this case we recommend cleaning by spreading some wax on the spot with a cloth till the stain is removed. Oily substances, on the other hand, produce stains that spontaneously disappear due to absorption. It is however possible to spread absorbing powder (such as talcum powder) and remove it in a few days. Trichloroethylene, acetone and diluent can be used without risk. In case these remedies fail to remove the stain, it is recommended to contact our firm. Efficient technical help will be granted.
