F. Restoration & Polish

 

Index:

F. Restoration - Leveling surface by wet grinding with silicon carbide and or diamond pads.

Hone Scratch removing by wet grinding with diamond pads. (A satin finish with a little or no gloss).

Polish - To bring the stone surface to shiny reflective state achieved friction abrasive and or chemical process. (A Glossy surface which brings out the full color and character of the stone).

Seal - A subsurface treatment formulated to penetrate the stone surface to enhance resistance to water& oil stains.

Filler - Thin mortar used for filling spaces between tiles or slabs Examples: Sanded, Nun-sanded, Epoxy.

Etch - Action or effect of an Acid -based compound on a surface. Seen as dull spots or ring caused by acid - based tile and grout cleaners, Vinegar, Wine, Fruit, Vegetables, Orange juice, Soft drinks, Etc..

Waxing - The application of a paste or a liquid wax to the stone to provide or maintain an artificial Polish.

Strip - To remove coatings : most commonly chemical coatings, but can be abrasive.

Poultice - A unique mixture to extract stains from natural stone.

General Direction for Grinding

To achieve a good result in grinding and polishing marble, Terrazzo, Limestone, Travertine etc.

A 15" to 20" floor machine should beused.

The grinding should begin near the walls,proceeding then gradually towards the center.

The machine must work Parallel to the wall.This way the borders can be level much easily, and the machinecan absorb the shocks caused by the roughness of the floorwithout knocking against the wall.

It is very important that the borders near thewall be leveled carefully, to prevent damaging of finer gritsagainst a lippage in the floor, and to avoid the long andnever-quite-perfect work of smoothing them by a hand grinder.

It is very important to choose the rightdiamond, bond and shape to match the requirements of the work tobe done.

The machine must never stand stationary inone spot when the motor is running. Use a medium swingingmotion.

Do not grind stone without water (dry).you can burn the stone (If this happens the damage is non -revisable).

Always be sure to apply water before startingthe machine. Do not use to much water. In tests for the optimalamount of water verses time, It has been determined that it isbetter to pour small amount of water on the low grits, andincrease the water supply when using higher grits.

When getting to low point (dips) in the floor,it is important to grind with a round movement to level a biggerportion of the floor to hide the wave. The waves will bemore noticeable after polish.

When grinding high lippage floor it is betterto grind from the high point towards the low point toprotect your diamond and to protect the high corner stone (fromchipping or collapsing).

For your knowledge only: the best polish hasbeen achieved with lead (not environment friendly in theU.S.).

In the next pages we will learn how to: Survey,Prepare, Safety, Grind, Polish & Crystallize.

Assuming we are working with a floor machine& A drive pad, with a Velcro attachment.

Grinding: 30 to 50 grit *(120Grit)

Cut (Lippage) to level the surface.

Tools:

-Lippage removal diamond.

-Resin bond diamond.

-Metal bond diamond.

-Classic Carbide stones.

Install the first cutting tools 1/2" fromthe edge (inside).

(Cutting tools or lippage removal should betapered at the edge.)

* Use 120 grit cutting tools for very delicateor vain Materials.

When cutting a high lipagge, work from the highlevel to the low (to protect your cutting tools).

Work the machine all the way to the walls.

Water: start the cutting with a very wet past like.

Honing: 120 to 220 grit.

Erase the cutting scratches.

Tools:

-Resin bond diamond.

-Metal bond diamond.

-Classic Carbide stones.

This time we will put the diamond only1/4" from the edge, to make shore we remove all the cutting scratches.

P.S. It is very important to rinse the surface between every grit, to remove all the last grit remains.

Water: every higher grit add more water.

Polish: 400 to 600-800grit.

Depending on the materials finish with low(600) grit on hard & high (800) grit on soft.

Tools:

-Resin bond diamond

-Classic carbide stones.

This time we put the diamond all the way to the edge, to erase all remain honing scratches.

Now we are ready for the finish polish.

I will recommend tow methods.

1. Powder (acid related)

2. Crystallization. (never use when floor is wet).

 

Crystallization (Polish Liquid)

Introduction

This process has been in use for 25 years in Europe.

It was invented in Barcelona, Spain.

You can polish forever with this method, you will never get a build up ( like wax ).

The process uses fluorescent compound such as magnesium, zinc, and aluminum.

The compound plus an acid, cause a chemical change on the surface of the stones

containing calcium carbonate.

The new surface is calcium fluoride:

1. The surface is more durable than the calcium carbonate.

2. The action produces a super shine on the surface.

3. It also creates a slip-resistant surface.

Instructions

1. Shake the material before use.

2. Do not spill the material on floor unless you polish that area immediately.

3. Spray some material on 9 tiles ( 12 x 12)" use steel wool No. 0 to 3

with a slow buffer (150 - 175)R.P.M. slowly work on those tiles until the liquid

dries and the stone shines. If you need to, do the process over again on the same area.

4. Steel wool No.0 will be good with new honed surfaces. No.2-3 will work very

well on old slightly scratched surfaces.

5. You don't have to grind over 400 Grit. when you use this process.

6. Don't polish a wet surface ( If you grind, don't crystallize the same day )

leave the floor to dry completely before you crystallize.

7. Neutralize the surface after crystallization specially light color marbles. (Wash with water & a degreaser etc.)

8. A gallon (5 Liter) will polish Apr.3000-5000 Square / Feet.

 

Gialotex (Polishing Powder)

Introduction

This is a polishing powder used mostly for marble, limestone & terrazzo.

It is made by "Aguila" from Barcelona, SPAIN.

The process uses fluorescent compound.

It is not as acidic as other powders, you can leave the excessive material for enough time to finish polishing150. Sq. Ft., and than rinse it off ( It will not etch ).

The new polished surface will have:

1. High traffic durability.

2. Glass-like look.

3. Slip resistance.

4. Used immediately after grinding.

Instruction

1. After you finish grit 400, or at the most800.( You won't need more )

2. Pour 3 Table-spoons on 10 Sq.Ft.

3. Pour 1/4 glass water on the powder.

4. Polish with a white pad, no extra weights, possibly a 300 RPM floor Machine.

5. Stay on the 10 Sq.Ft. for 8-12 minutes, or until you get the shine you want.

6. Do not polish dry, use more water if necessary to create a paste like compound.

7. Squeegee the remains to the other 10 Sq.Ft.,( Recycle ) add more powder and

continue.

8. After polishing a room or approx.. 150 Sq.Ft. rinse the area with same pad

with a lot of water.

9. The floor is ready for presentation.

 

Tip:

In case you want to polish black or green marble, it will be faster and nicer to use crystal polish,

as a finisher after a pre-powder polish ( let the surface to dry well before crystallization ).

Prepare and Protect

It is extremely important to prepare &protect the job site. Including sealing the walls with plastic masking tape etc.

The polishing compound we are using are acidic so it is important to protect all metals, marble moldings fixtures glass and so on.

Be very careful with the customer furniture and property act like it is your own.

 

Polishing Diamond or Chemicals ?

(Marble Terrazzo Limestone)

/by Pini Barak

Diamond: 60 to 8500 grit.

The process of getting the surface a smoother and smoother so that no light ray will get lost ( mirror reflection ).

a. The surface doesn't change chemically.

b. Reflection is good but poor depth.

c. Color O.K. dark materials not darken enough. (only marble).

Chemicals: Crystallization, Acids, Tin oxide, Lead, Etc.

The process doesn't require high grit finishes (marble 400-600),(granite 800-1200)

It is a faster process than diamonds.

The chemical reaction change the surface material from Calcium carbonate to

crystal carbonate.

a. A very deep reflection ( mirror look ).

b. Nice colors specially dark ones.

c. It hardens the surface material It means you get a better scratch resistance.
