Preparing and cleaning the surface

1. Carefully clean the surface, making sure to remove any dust or dirt present.

2. Never apply LIMESTONE DENSIFIER to wet surfaces. The product can be used on slightly
damp surfaces; nonetheless, please ensure that the surface to be treated is as dry as possible.

3. Apply LIMESTONE DENSIFIER to surfaces with a temperature of between +5 and +40°C

4. Any adjacent surfaces not being treated with the product must be protected.

Product dilution

The product is applied pure or diluted accordin to the type of surface where is applied

Use the product pure if applied on high absorbent materials with a porous and rough surface
such as hand-made terracotta, outdoor concrete pavers

Use the product with 1:1 or 1:2 dilution if applied on absorbent materials with a compact and
regular surface such as industrial cotto or cementine

Application to aid polishing

LIMESTONE DENSIFIER must be used as part of the mechanical polishing process on supports
previously sanded with 200/400 grain. To speed up the whole process, it is advisable for the
preliminary sanding process to be carried out dry so as not to wait for the surface to dry before
applying LIMESTONE HARDENER. In the event this preliminary sanding operation is carried out with water, it is necessary to wait at least 24-48 hours before applying LIMESTONE DENSIFIER or to cut out this waiting time, it is possible to apply LD before commencing with the first mechanical polishing grain sizes; this will drastically limit the amount of water absorbed by the surface, allowing immediate drying for the following steps before re-applying LIMESTONE DENSIFIER. Once LIMESTONE DENSIFIER has been applied to a dry surface, it is possible to continue with the polishing process, using the next grain up from the one used before the LIMESTONE DENSIFIER. This second part of the polishing process must be carried out with water. Thanks to LIMESTONE DENSIFIER, the surface can be treated with finishing chemical polishes after the 800 grain size has been used, which may already correspond to mechanicalpolishing carried out with particularly fine grain (1500-3000)

5a. On dried, cleaned and sanded surfaces, apply an abundant, even layer of product using a
lambswool applicator, roller, brush or airless applicator or any other tools for the purpose. Make sure to create an even layer to cover the whole surface being treated. In case of application to especially absorbent surfaces, proceed to apply a second coat of product, following the same
method, at around 1-2 hours from the first.

6a. Considering that the resulting surface will need further mechanical polishing, it is not
necessary to concentrate on any residual products, which will be removed in successive stages.

7a. Proceed with the next level of polishing grain no less than 4 hours after applying LIMESTONE DENSIFIER. We recommend in any case to proceed on the following day to allow the LIMESTONE DENSIFIER to spread and cure completely.

The application of LIMESTONE DENSIFIER to aid the mechanical sanding process is also possible before laying slabs or tiles.

Application as a deep penetrating, water-repellent treatment against rising damp and dirt

This operation is generally carried out in the factory or on site, including a short period from
material installation. Usually, material for laying is treated during the “dry laying” stage, which is frequently used as it allows the position of each single piece to be assessed. Alternatively, we
recommend laying out the material on a clean, dry area that is large enough to treat the natural
stone slabs or tiles.

The natural stone pre-treatment stage using Faber Chimica solutions starts from the upper
surface of the material (top) and then the sides (edges), followed, after the product has dried,
with the underface, which will be in contact with the glue (bottom).

5b. Apply a layer of product, taking care to create an even coating that covers the whole
surface, including both the top and edges of the slab or tile. After about 5-10 minutes and in
any case, before the product dries, even out any product residues remaining on the surface,
taking care to distribute them uniformly with a roller, lambswool applicator or brush. For a
perfectly clean surface in this stage, we recommend redistributing residues until they have been
completely eliminated. This redistribution operation is essentially important since it allows easy
removal of any dry residues on the surface of the material, which if not re-distributed will be
particularly hard to remove.

6b. Wait around 1-2 hours for the product to dry; reposition the slabs or tiles in order to be able
to treat the underside (bottom), proceeding as described above. We recommend re-positioning
the slabs and treating the underface (bottom), starting with the first slab to have been given top
+ edge treatment.

7b. The product residues, redistributed as described above, can be easily removed once the
material is completely dry and before it is boxed up, using a white pad or a damp cloth. It can
also be removed directly on site, before the slabs or tiles are laid, using a white pad or damp
cloth, or immediately after laying, using a floor polisher with white disc.
If the material laid needs to be polished, the residues will be removed directly during the
polishing operations.

The pre-treatment on 6 sides (top+edge+bottom) with LIMESTONE DENSIFIER can be carried
out using roller, brush or lambswool applicator, or by completely immersing the individual tiles
or slabs of material. In this case, fill a large enough container for the tiles with product and
completely immerse one tile at a time, for about 10-15 seconds. Immediately after, proceed to
redistribute the product residues over the surface, as described above, using a clean cloth.

Drying time for pre-installation treatment.

Before proceeding to lay the tiles or slabs treated with LIMESTONE DENSIFIER wait at least 24 hours.

Opening to floor traffic after pre-installation treatment

Once laid, the treated slabs or tiles can be opened to foot traffic.

Production line application

The product can be applied using special equipment as part of an industrial
production/treatment line. Based on the characteristics of the line available, the product will
generally require an application stage using a sprinkler, silicone roller or other suitable means;
this must be followed by the removal of residues, to be carried out with special brushes or pads.
