Stones have different finishes or surface textures
according to their formation. But these days, stones
are fabricated to give desired surface textures.
There are seven main types of surfaces that
are in use:
Natural
The natural surface texture is achieved by ripping
along its line of cleavage to reveal the natural
grain & texture, which gives an undulating surface
with great character. The surface comes with natural
clefts giving a very natural look.
Honed
It is produced by grinding a surface with high grit
material to a uniform specification, without producing
a reflective surface. Honed stone colors are not
as vibrant as polished stones. A smooth finish with
a slight sheen is produced by using a polishing
head. This surface is very smooth, but often very
porous. Honed finishes, unlike polished finishes
are not reflective. The honed finish is a satin
smooth surface with little light reflection.
This finish is often used on walking surfaces and
other areas where heavy traffic would wear off a
polished finish. Honed finishes are used in interior
wall covering. It can also used on the exterior
in warm environments, table tops, very light duty
residential flooring, novelty items, etc.
Polished
Polished surface texture is a reflection of polished
crystals that bring out the brilliant colors and
grains of natural stones. The shine on stone surface
comes from polishing bricks and powders used during
fabrication and not from any coating. Polishing
can be done only on crystallized stones and doesn't
affect the porosity of the stone. Polished finish
is quite popular as it enhances the colour and markings
of the material. A stone with a polished finish
is very smooth and reflective.
This type of finish is used in reception areas,
where marble, granite and some harder limestones
are laid. The most popular uses of polished stone
are in interior and exterior wall cladding, interior
and exterior paving, fireplace facing and hearth,
lavatory tops, residential & commercial countertops,
table tops, novelty items, many non-architectural
uses such as tooth paste, paint whiting, agricultural
lime, etc.
Flamed
It is a rough surface that is developed due to the
bursting of crystals when the stone is heated. This
surface gives an irregular textured finish. The
flamed finish is a rough texture used frequently
on floor tiles and vertical applications. Color
and particulate or vein patterns vary from block
to block. The major uses includes - chemistry and
fire resistant work surfaces, fireplace facings
& inner hearths, etc. where heat is an issue.
Sand Blasted
Producing a finish similar to cleft, sand blasting
involves projecting a high-pressure airline coarse-grained
grit, onto the top surface of the stone. It is characterized
by a textured surface with a matte gloss.
Sawn
Sawn surface is coarsely polished leaving a semi-smooth,
regular finish. It is done by using a gang saw.
Saw cut finish has acquired its name owing to the
saw cuts that are made on the surface of stone.
When the stones are broken free of the cut layer,
they are shaped to uniform size. Saw Cut finish
offers complimentary accent to other types of stone
work. It is generally used for walls, gate entries,
patios, landscape design applications, etc.
Bush Hammered
A pounding action that develops a textured surface.
The top surface is pneumatically tooled to produce
a pitted or grooved surface finish.
