Preparing and cleaning the surface

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

2. Never apply BS H2O 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 BS H2O to surfaces with a temperature of between +5 and +40°C

Application as back treatment

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 used for the
top and sides has dried, with the under-face, which will be in contact with the glue (bottom),
where BS H2O will be applied.

4 After treating the 5 sides (top+edge) with the best possible product for the type of material,
and after turning over the dry tile/slab, apply a layer of BS H2O to the underface, taking care to
cover the whole surface.

Drying time for pre-installation (back) treatment.

Wait around 15-30 minutes for the product to dry before handling the material: it is necessary
to wait at least 24 hours before installation.
