Hello,
I was doing some browseing on stone and concrete
polishing when I came across this forum. After reading a few comments from members I decided this would be a good place to spend some time for a beginner like myself. I have polished a few
marble floors and a trazzo floor with good success. Of course I really don't have anything to compare that to other than the customers liked the job so I guess that what counts.
Hopefully though I'll "HONE" my skills and start marketing more toward the hard surface stuff. It seems to be more lucrative than sucking dirt out of carpets. I bought a cimex diamond series with the extra weights. It seems to get the job done but it dosen't get to close to the edges. I have found that is the crappiest part of
polishing is the edgeing. Little hard on the knees and back using a hand polisher.
Anyways, if you haven't noticed I can be a little long winded so I'll say good-bye and hope to learn alot from you pro's.
Thanks!

 | | Marble | MARBLE: CHARACTERISTICS
This standard includes general information on the characteristics
and common uses of marble and identifies typical problems
associated with the material.
INTRODUCTION
Marble is an extremely hard, metamorphic stone composed of calcite
(CaCO3). It is formed as a result of the recrystallization of
limestone under the intense pressure and heat of geologic
processes. The effect of this process is the creation of a stone
with a very tight crystalline structure and small but definite
porosity. Because of its structure, marble can take a very high
polish and is a very popular decorative stone for architectural and
sculptural uses. The limited porosity of marble, especially
polished marble, makes it less vulnerable to the leaching effects
of water. Calcium carbonate, however, of which marble is composed,
is highly susceptible to attack by acidic agents. Marble is
readily dissolved by acids, even very dilute acids, however the
actual results of acidic exposure will vary with the nature of the
acid. Chlorides, nitrates, sulfates and other chemical compounds
react differently with marble and produce various by-products,
which have a wide range of solubility and impact on the durability
of marble. For this reason, it is always important to determine
the exact type of pollutants causing marble deterioration.
Marble itself can be of two types, one composed of calcite and the
other of dolomite. Dolomitic marble is much more resistant to acid
attack than calcite marble. The color of marble ranges from the
brilliant white of calcite to black, including blue-gray, red,
yellow and green, depending upon the mineral composition.
TYPICAL USES
Marble has many decorative and structural uses. It is used for
outdoor sculpture as well as for sculpture bases; in architecture
it is used in exterior walls and veneers, flooring, decorative
features, stairways and walkways. The way in which the stone is
used may be a factor in limiting or controlling the severity of
exposure. The use or function of the marble may also affect the
feasibility of applying certain treatments, but type of use is not
the primary factor in the major types of deterioration and damage
to which marble is susceptible. | |  |
