ADVICE FOR INSTALLATION



The choice of installation technique is made based on that fact that this is a calibrated, compact and not very absorbent material and has other mechanical features such as its surface hardness, shock resistance, wear and tear, etc that is often installed in very stressed environments.
Based on our clients experience, we suggest the following installation methods: Installation on mortar,installation with adhesive for tiles.

The use of one or the other system, must be chosen in consideration of the use to which the slabs will be subjected. However you decide to carry out installation, it’s important to first create a compact and resistant concrete screed that can prohibit the settling or flattening process, particularly under high usage conditions.This occurs on the foundation or directly on the ground based on the soil type. Composed of cement screed with 250-400 kgs for m3 of sand, it must be very compact and must have an adequate thickness for the operation loads. Sometimes, the screed can also be reinforced by single or double welded metal mesh.
Preparing the screed and the area to be paved for either motor vehicles or pedestrians must be calculated by the designer according to the traffic that it must support.

N. 1 - Pouring Screed (System used for pedestrian transit, medium and heavy vehicles)

The traditional system is most often used when the substratum must be raised or leveled. It consists in using a screed bed between 4-6 cms thick with 300-400 kgs of cement; the cement is poured and leveled in an area proportionate to a limited number of tiles to be laid and a 8/10 mms layer of cement grout is poured over this. The tiles are laid and gently struck to level. If appropriate, place the correct technical dilationjoints on the screed bed.

CAUTION: ABSOLUTELY DO NOT USE POWDERED CEMENT INSTEAD OF GROUT (EVEN IF WET), PARTICULARLY FOR MORE DIFFICULT APPLICATIONS, AS THE TILES MIGHT NOT AFFIX.

Wait at least one week before allowing normal traffic in the floored area.

Preparing the area to be floored for either motorized vehicles or pedestrians must be calculated by the designer according to the traffic that it must support. This is the resistant part that supports the pavement and its physical-mechanical conditions must remain unaltered over time. It must not be compressible and deformable.

After installation, protect the slabs for at least 24 hours from rain of from direct sun.



N. 2 -Installation with Adhesive for Floorings (System used for pedestrian transits)

This is the preferred system for regular and already leveled foundations. It consists in making a leveled foundation composed of sufficiently seasoned and dry screed cement (1 week per centimeter of thickness). Then lay down a layer of adhesive for excellent quality flooring for marble, granite and natural stone flooring only and specifically for outdoor use. Adjust the tiles and gently strike them to level.

Check the suitability of the screed or plaster before installation. It must be dry, solid and compression resistant. The floor must not have any removable parts, dust, grease, oils, waxes, varnishes, release agents or anything else that could prohibit the adhesion of the tiles. For pre-mixed installations, verify that they are appropriate to use with a coating.

Note: For more difficult applications, use coarse-grained adhesive with a 12/15 mms serrated knife.

Suggeriamo l’applicazione della “ doppia spalmatura “, che consiste nell’applicare l’adesivo sul fondo di posa ed imburrare il retro della lastra. Questo procedimento permette un’ottima adesione anche nel caso di formazione di pelle. la doppia spalmatura consente il letto pieno nel retro della lastra.

After installation, protect the slabs for at least 24 hours from rain of from direct sun.

Squaring:
FOR SERIES FOR EXTERIORS E-F-B-M :
Any excess cement of adhesive that is visible during the installation of the slabs is immediately removed with a sponge or wet broom. We recommend not to seal the quadratures, or saled with silia sand.

The use of only cement for tiled surfaces is absolutely prohibited. After installation, protect the slabs for at least 24 hours from rain of from direct sun.


The company guarantees the quality about only of its own products. FIMAS srl isn’t responsible for negative results deriving from wrong installation system or wrong use. It has no responsibilities according the law (civil and penal code). The company, in fact, for some logistical reasons can’t be present at the installation of our products in the construction site. For this reason, FIMAS can’t check thecorrect use of these advices and it can’t stand in for works supervisor
