Practical methods of operation
The polishing and final polishing operations for
marble, stone, granite, etc. described below must
be performed in the order stated for trimming,
smoothing, jointing, polishing and final polishing.
It should be considered that, despite the
difference in the hardness of the different
materials, both in terms of their mixture and their
homogeneity, the trimming and polishing
operations are identical but not the same for all
the final polishing operations. We will return to this
in the last section.
This operation consists of making the first pass
with the machine after the flooring has been
laid. The granular size of the initial abrasive is
determined by the surface's regularity and the
method in which it has been laid: The greater
the discrepancy, the larger the size of the
• Paved floor: whether to standard dimensions
or not and whether in marble, stone,
conglomerate, cabochon or not.
• If the slabs are laid regularly and if the joints
do not form fins greater than 1 or 2mm, use
magnesia segments with a granular size of 0.
Magnesia conglomerate
Prismatic segments - Rep. 100
• Granule size
• 5 Star Super
If the slabs have larger fins, we recommend
the use of a Bakelite crown wheel with a
granular size of 16 Q in dry application
(contact your supplier for information).
• Floor in the form of "MACHINED" or
"RUBBLE" rock
The opus may be either stone or marble, the
joints are usually in granito, i.e. crushed
marble mixed with cement and colorant, the
joints must stand proud by a few millimetres
and for this reason a Bakelite rough stone
block crown wheel with a granular size of 16
Q must be used.
• Granito, with or without joints
For the first pass, we recommend once again
the use of a Bakelite rough stone block crown
wheel with a granular size of 16 Q. If this flat
and well worn, with no significant bumps, use
magnesia segments with a granular size of
This operation, after trimming, consists of
reducing the marks caused by the use of
coarse-grained abrasives before the floor is
For all types of paved floors, magnesia
segments with a granular size of 1 are
This operation, which intervenes between
granular sizes 1 and 2, is essential for all paved
floors, whatever the material.
It consists of resealing the holes caused by air
bubble sin the cement joints or in the paving:
this can be done with a liquid slip, comprising a
mixture of white cement and a colorant matching
the colour of the paving or with quick-drying
mastic (please refer to the STONIX details).

performed, namely polishing.
