Sandstones have different surface textures, which varies according to their formation. However now a days the stones are fabricated as the desired texture and the usage. There are six main types of surfaces that are in use.
The natural surface texture is achieved by ripping along its line of
cleavage to reveal the natural grain & texture. This texture gives an
undulating surface with great character. The surface comes with natural
clefts giving a very natural look.
texture provides a rough surface. The roughness in the surface is a result
of bursting of crystals when the stone is heated. Such a surface gives an
irregular textured finish.
Polished surface texture is a reflection of polished crystals. Such texture
brings 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.
The honed texture is produced by grinding a surface with high grit material
to a uniform specification, such that it does not produce a reflective
surface. Thus 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.
A pounding action that develops a textured surface. The top surface is
pneumatically tooled to produce a pitted or grooved surface finish.
Sawn surface is coarsely polished leaving a semi-smooth, regular finish. It
is done by using a gang saw.
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.
