Floor Restoration & Surface Preparation

Tech-Notes & End-user Manuals -

Natural stone floors, especially in a high-traffic commercial areas
become dull and lose their shine when the sediment and grit (sand
that people bring with their shoes)
start eroding the stone’s crystals.
The foot pressure forces the sediment lying on the surface, causing
an abrasion and fracturing the delicate crystals of the stone.

The only safe and proper way to restore the crystals natural ability to
reflect light evenly and provide a brilliant shine is to re-hone & re-polish
them by using diamond abrasives, engineered and designed particularly
for Granite and/or Marble works.

Specific types of diamond superabrasive discs are used through the
various stages of the floor restoration process.

Metal bond diamond discs (called matrix diamonds) are used for rough
grinding, heavy stock removal, leveling and flattening the floor.

Electroplated diamond discs are used on Marble & Terrazzo.

Sintered and brazed diamond discs are used on Concrete, Granite
and Marble

Rigid resinous diamond discs are used to grind, hone and polish the
floor surface.

Most natural stones are composed of minerals that vary by hardness
to one another. Using diamond discs that flex and float (designed for
edge polishing applications)
cause an uneven polish. Flexible diamond
polishing pads and/or discs have the tendency to remove more of the
softer portion of the stone, causing a 'wavy' appearance and uneven
reflection on the surface.

Resinous diamond discs with different diamond properties and bonding
agents are used on Granite and Marble applications.

Mechanical diamond polishing is a very orderly, multi-step process.

If there are any high-low areas present (commonly known as lippage)
the floor should be ground flat using the metal bonded diamond discs.
It is very important to make sure that all prior scratches are removed
before moving onto the next grit step.

Each diamond grit step requires an average of 4 passes, depending
on the density of the particular stone and its current condition.

If the floor is worn and scratched, begin with the metal bonded
diamond superabrasives.

Once the floor is leveled, continue with the resinous diamond discs
and begin with a grit size equal to the one of the metal bonded diamond
discs that you've just completed or a step lower. That will ensure there
won't be any scratches and swirl marks left from the previously used
metal bond diamond superabrasives.

Rinse the surface well in between every grit in order to remove all of
the excess material remains.

Once the grinding stage is entirely completed, continue through the
honing diamond steps. Many Marble stones and Terrazzo are capable
of taking a polish immediately after completing Grit 400.

However, Granite, green Marble (Serpentine) and some other Marble
stones require higher honing steps, prior to the polishing.

After the last honing step is completed the stone's crystals will begin
developing a low shine and will be capable of taking a higher polish and
developing a reflection.

Determine which polishing technique will be the most suitable for the current floor application.

If you're doing Granite -

For optimum results, depending on the diamond system used, we recommend that you continue to work your way through the polishing
diamond steps up to the final polishing stage - the BUFF and the FINAL
BUFF (FGS Diamond System only. For
best performance use the BUFF
& the FINAL BUFF discs in sequence
) or the DF (RRD Diamond System)
where the water-flow is being reduced to a minimum allowing the stone
to get well heated and to transfer the generated heat onto the buffing
discs, 'triggering' a chemical reaction between the compressed high polishing alloys the discs are made from and the stone's crystals,
causing the developing of a superior shine - a Gloss height of
over 90 units gloss reading and a brilliant mirror reflection
on the stone's surface.

If you would like to additionally enhance the depth of the reflection
and further enhance the color, and increase the gloss, you may take an
extra step and re-polish the surface using a polishing compound.

Choose an environmentally safe polishing compound designed specifically
for the restoration of the kind of stone - Light or Dark Granite you are
working on.

Obtain and read thoroughly the M.S.D.S. (Material Safety Data Sheets)
and strictly follow manufacturer's instructions.

Quality polishing compound will provide consistent appearance-curve
and better scratch resistance & will reduce further direct maintenance

If you're doing Verde Marble -

Specially formulated polishing powder is used for the unique qualities
of Green Marble. The stone must maintain a surface grit of 1800 and
higher in order to produce factory polish luster if additionally needed.

If you're doing Marble or Terrazzo -

Many Marble stones and Terrazzo (man-made stone) are capable
of taking a polish immediately after the honing 400 grit diamond step
is completed. Most marble polishing powders available on the market
perform fairly well and provide excellent results.

However certain Marble stones such as Botticino, the Greek Thassos
White and others require will higher honing/polishing diamond steps and
hotter polishing compound.
(meaning powders with a higher concentration of oxalic acid)

If you're doing Limestone or Travertine -

In general, restoration of Limestone and Travertine floor surfaces is
done in the same manner as Marble restoration.

Specially engineered nickel bonded diamond grinding and honing discs
are available for porous natural stones such as Limestone & Travertine.
Manufactured with fully exposed diamond surface these superabrasive
diamond discs facilitate rapid and aggressive action, providing smooth
finish and reducing direct labor & tool-costs.
Polishing compound may
be applied immediately after the last honing diamond step - Grit 400
or 600 mesh is entirely completed.

If you're doing Concrete Restoration -

The Concrete restoration process is quite similar to the restoration
techniques applied on Granite & Marble floor surfaces.

Sintered metal bonded diamond superabrasive discs are used to grind
and flatten the floor.

Resinoid diamond discs (FGS-N Diamond System) are used to remove
the scratches left from the previously used metal bonded diamond discs. Specially formulated Concrete hardener is applied to the surface prior to
the honing diamond steps (Or after, depending on the particular type of
product used). The process continues through the honing - Gr. 200/400
and the polishing diamond steps bringing the outstanding Concrete floor
application to a factory finish (Surface grit 1800/3500).
