Parameters definition :
Polished - To smooth
or brighten a surface increasing the reflective quality and luster
by chemical or physical processes. Generally gloss levels should
be + 90 as measured by a gloss meter. To achieve this, final polishing
should have been done by latest Italian/ French machines using imported
Buffing: Using a non-abrasive
pad attached to a machine, which rotates the pad in a circular fashion
over the stone, generally between 150-300 RPM. Polishing formulations
containing micro-fine abrasive materials are used with buffing to
produce a more reflective gloss on the surface of stone. Waxes are
also used with buffing to enhance the gloss of polished stone.
Honed: To grind a surface
with a high grit material to a uniform specification without producing
a reflective surface.
Sawn - i.e. unpolished. It
is not advisable to buy this way because : floor polishers do not
give as good a polish as factory machine polishers. many defects
are not visible easily before polishing.
Calibration: To grind a surface
with a high grit material to a uniform surface to maintain the thickness
Gangsaw: To grind two sides
of the stone surfaces with a high grit material to a uniform specification
without producing a reflective surface.
Shade variation - Slabs / tiles
should be sorted to ensure uniformity of shade. Normally, any colour
can be sorted into three shades. Sorting is simple -just lay all
the material on the floor and look from different directions.
Colour patches - These are darker
or lighter patches or bands of single colours due to mineral localisation.
Scratches: The marring of
the surface caused by physical trauma such as small stones or sand
embedded in shoes scraping across a marble floor.
Staining: The absorption
of foreign pigments or oils into the porous stone causing discoloration.
Double color - Sometimes two different
grain sizes occur in the same slab, giving the appearance of a double
Free lengths : i.e. lengths varying
randomly while width is constant are also very attractive. Choose
the widths as per the expected floor area. Buy random lengths and
cut at your site to fit.
A 4 dimension in any direction on the surface
shall determine variation from true plane, or flat surfaces. Such
variations on polish, hone, and fine rubbed surfaces shall not exceed
tolerances listed below or 1/3 of the specified joint width, whichever
is greater. On surfaces having other finishes, the maximum variation
from true plane shall not exceed the tolerance listed below or +
3 mm of the specified joint width, whichever is greater.
Polished, honed or fine rubbed finishes...
+ 0.5 mm
Sawn, Calibrated, 4-cut and 6-cut....
+ 1 mm
Edges also can be chamfered / bevelled.
Chamfering removes whiteness and chipped edges. This looks very
good. Chamfering is a simple process in which a polishing brick
is run at an angle of 45 ?.
Quality Details :
a. One Side Fine Mirror Polished.
b. Gangsawn/Cutter side
c. Thickness variation is + 0.5 mm to 1 mm depending upon Tile/Slab.
The stone is available in a range
of eight smooth and textured finishes:
- HONED a smooth finish with a
slight sheen, produced by using a polishing head.
- WATERJETt: a non-slip matt finish,
produced by working the surface of the stone with high-pressure
- sanded: sawn stone slabs are
coarsely polished: this removes saw marks and leaves a semi-smooth,
- CLEFTt: with this traditional
treatment the stone is riven along its line of cleavage to reveal
the natural grain; this gives an undulating surface with great
- GRITBLASTED: a high-pressure
airline projects coarse-grained grit onto the top surface of the
stone producing a finish similar to cleft, but available on slabs
of greater size.
- FLAMED: the top surface of the
slab is burnt off, giving an irregular textured
- finishtextured: the top surfaces
of sawn slabs are pneumatically tooled to produce a pitted or
TILES AND SLABS ARE PACKED
IN STYROFORM BOXES AND ARE FURTHER PACKED INTO WOODEN CRATE.
POLYTHENE WRAPPER IS MADE TO COVER THE ENTIRE MATERIAL INSIDE
THE WOODEN CRATE. FOR RANDOM SLABS, EACH SLAB IS PACKED IN A SEPARATE
POLYTHENE WRAPPER, TO REDUCE OR TO AVOID SCRATCHING OF TILES
AND SLABS WHICH ARE PACKED FACE TO FACE.
