There are numbers options to achieve the high degree of shine on stone surfaces.
Today’s advance technology with the right stone care products, equipments and
proper maintenance procedures can provide superior results in maintaining all
types of stone.
1. Waxing
The most common system used for stone is waxing. This gloss restoration process
is simple, economic and effective. The application of waxes can be applied by a
cloth, or a mop or a wax applicator on stone and leave to dry. Gloss can be
achieved with no need to polish. Spray buffing using low speed floor machine
(175 rpm) or a high or ultra-high speed burnisher (1000-3000 rpm) with suitable polishing pads. The wax coatings provide stain resistance
and ass luster to stone surfaces, delivering a high gloss and outstanding
appearance. Since waxes are much softer than stone itself and have low durability;
they require frequent buffing and multiple applications. Most waxes will turn
yellowish and become easily scratched, scuffed and marred, and complete stripping
maybe necessary in such cases. Stripping pads and chemical strippers can do much
of damage to stone surface.
2. Crystallization
Crystallization is a one step spray on buff system that goes on easy and fast.
The process is quite simple, place a steel wool pad under a standard buffing
floor machine; spray a chemical compound fluid (commonly called crystallizer)
and then buff in an overlapping side-to side motion until dry. The steel wool produce heat during fractionizing, and the
acids in the crystallizer breaks the calcium carbonate and react with certain
minerals in the marble, forming a new glossy type crystal compound on the surface.
Although this vitrified layer gives a hard transparent shinny film (coating) with
slip resistance and color enhancement, it will turn dark and yellowish rapidly
and also block the breathing of the stone, even may cause trapping of moisture.
Important: Crystallization process works well on calcareous stones such as marble,
limestone, travertine and marble base agglomerates. It may also apply on granite,
however, the result will be different. Crystallization cannot be used on quartz or
quartz base stone, sandstone and slate.
3. Polishing Powder
Polishing Powder is a buffing compound consisting of superfine abrasive and many
other chemical ingredients specially formulate to achieve the original high nature
gloss factory finish. The abrasive materials, contained in powder abrade and
smooth over the stone surface, produce a gloss appearance and also remove minor
scratches, light etching, water marks and dullness. The process is extremely
simple, requiting little practice, inexpensive and yield incredible nature gloss
and shine in a very short time. The powder polishing does not develop a film or
a coating, stripping is never required. It is also used in stone fabrication
factory or use in final-stage polishing after re-surfacing with diamond abrasive discs and as a periodic maintenance system with
great success.
Place approximately one table-spoon of polishing powder on the stone floor for work area about 12-15 square feet at a time and add water to obtain a slurry (or mix before and
sprinkle the slurry mixture directly). Begin to buff with a white pad under a
175 rpm floor machine until the desired shine is achieved. While buffing, always
keep a slightly slurry on the stone. If the slurry begin to dry, spray or add
water as needed. Vacuum up the solution and rinse with clean water.
Note: polishing powder is available in two primary types:
i) Marble Polishing Powder
ii) Granite Polishing Powder
4. Polishes
Polishes is a ready polishing refinisher in form of a paste, a cream or an
emulsion specially made for renewal and maintenance of polished stone surface
subject to high traffic and for won surface. Polishes also allow to re-establish a good sheen degree and improve the power of resistance to foot traffic
and provides slip resistance. Some polishes is in two-part system consisting of a powder and the paste which are mixed and buff. The
process is similar to powder polishing, shake the polishes well before using and
sprinkle 20-30 g of the polishes on the stone floor for work area about 12-15 square feet at a time. Buff with a white pad under a 175 rpm floor machine
until the desired level of gloss is achieved. While buffing, keep slightly slurry
on the stone surface. If the slurry begins to dry, spray or add water as need.
Vacuum up the solution and rinse with clean water. For worn surface, repeat the
application.
Polishes can also apply in dry polishing method. Dry polishing requires only
with a steel wool pad and buff until the polishes dry. Then mop and remove the
residue (Do not use water on steel wool pad).
Note: Polishes available in two primary types:
i) Marble polishing cream/paste
ii) Granite polishing cream/paste
Conclusion:
No matter it is maintenance, cleaning or protection of stone; proper care of
stone is always a profitable and useful service. Because you care, you will have
a beautiful and long-lasting natural stone walls or floors. Remember it will be much easier and less
expensive to properly clean and maintain the stone from the beginning than to go
through costly refurbishing and restoration.
