Fine Stone Restoration

Restore The Factory Finish Of Honed Marble

and Limestone - Without Machinery

Fine Stone Restoration of acid etches

Not sure if an Aldon product is right for you? Good! You never know if the results will be exactly what you expect until you try it on your project. Order   Samples of Aldon products  and eliminate the guesswork. See label reproduction below for application instructions.

The term "fine stone" is not in reference to the stones themselves, but to a certain type of factory finish grind of marble, granite, and limestone. The "fine stone" finishes are very smooth finishes called "honed" and "polished".

"Honed" typically looks and feels "soft" and has low reflectivity. "Fine Stone Restoration" is used to restore this kind of finish.

"Polished" typically looks and feels "mirror like" and is highly reflective. "Fine Stone Restoration" can be part of the process used to restore this kind of finish. See description below.

To add to the inevitable confusion, there are varying degrees of finish where the more highly polished "honed" finishes approach a "polished" finish.

This product, "Fine Stone Restoration", will restore to the "honed" level, but not to the "polished" level. It takes a special polishing compound, and sometimes a polishing machine to achieve that "mirror like" finish. Inquire with your stone dealer.
Or, there is another option. Aldon S-B-S Sealer is available in spray cans.

     S-B-S Sealer
This sealer is sprayed on shiny finishes like polished marble to protect them from damage. The spray can provides the ability to get a nice, smooth, glossy finish. When you have restored the finish with "Fine Stone Restoration", the "S-B-S Sealer" might even out the gloss sufficiently that the repaired section is no longer visible. This restoration process is not difficult, but polished marble shows every flaw. The sealer is easily removed and redone if the first application does not meet your goals.

For those situations where it is desired to reduce reflectivity and/or "soften" the look, this product is also used to convert a "polished" marble or limestone to a soft, matte "honed" type finish.

Limestone and Marble are a type of stone that reacts with acidic liquids. Even light contact with weak acidic liquids like fruit juice, wine, vinegar, some cleaners, etc. will deteriorate the finish enough to create a "dull" appearance. Heavier contact and longer time can actually eat depressions into the surface.

The "fine stone" (honed, polished) finishes are created by machine grinding with finer and finer grits and grinding compounds. "Fine Stone Restoration" lets you duplicate that finishing process by hand. This makes it practical to refinish small areas without the need for the specialized techniques and machines of a professional.

PRODUCT CHARACTERISTICS:

  • Water base. Little or no fumes, therefore, although all common sense precautions should be taken as with any chemicals in an inside environment - less concern than with solvent based products.
  • "Fine Stone Restoration" is a process on the raw stone. Therefore, all sealers, coatings, etc. that have ever been used in the past must be removed first. See Premium Stripper for the surface preperation.
  • Requires "0000" fine steel wool for finishing to the "honed" level.
  • Requires a "sponge sanding block" for the first stage of restoring deep depressions.
  • No grinding or polishing machines needed, therefore, a closely controlled and non-messy process.
  • See the product label reproduction below for all the information on surface preparation, application technique, drying time, etc. This label reproduction will always be the most current. Because we are constantly improving information and passing on tips from users, this could be more up to date than the label on the container.

These pictures follow the process of restoring a piece of honed limestone etched with a hydrochloric acid solution. This acid is far stronger than the acidic liquids normally found in the kitchen and bar. Your results may vary with stone type, softness, your technique, etc.

Before contact with acid.

Note the reflection of the round flood light bulb here, and then as it changes in the following pictures.

On the left is a puddle of water. On the right is an "X" shaped puddle of acid. Note the fizzing as the acid eats into the surface.
After wiping up the liquids. Note the reflection changes into a dull pattern created by the upper right leg of the "X" shaped acid puddle. The surface is lightly eaten into at this point. The effect is extreme loss of glossy finish, but not yet deep pits in the stone.
Acid has been applied again to achieve a deep etch. Red arrow shows the deep pits created by the acid.
Step 1 for restoring a deep acid etch or heavy scratch. This step is not necessary unless the etch is deep. Therefore, if it is only a flat, dull area - go to Step 2.

A small puddle of "Fine Stone Restoration" is rubbed in a circular pattern with a hardware or paint store "sanding sponge" and with medium pressure. Drag is noticable and lessens as the pits are smoothed out. This took less than one minute.

The bottom of the pits designates a new low point in the surface. The ending goal is to not just smooth out the pits, but to have the change from high to low over a wider area so as to be undetectable. Therefore, it is advantageous for the circular rubbing pattern to be larger than the etched area. This larger pattern creates a gentle slope down to the place of the deepest depression. The sponge compresses and conforms to the surface, which makes it easy to achieve a smooth and even feel across the stone face.

Add more "Fine Stone Restoration" and continue until surface is smooth.

Etch is smoothed out and the finish is smoother, but not back to the factory finish smoothness and gloss yet. It is now ready for Step 2.
Step 2. A small puddle of "Fine Stone Restoration" is rubbed in a circular motion with #0000 steel wool (available at paint and hardware stores). Process is repeated until finish is restored. With this stone it took 2 applications and approximately 3 minutes of rubbing with medium pressure.
Finish is restored and is virtually undetectable from the original factory finish. Use Aldon Insta-Clean to remove all residue - then apply sealer per the recommendations for your stone type in the  Pros/Cons And Pictures Of All Surface Types  section.

 

TROUBLESHOOTING:

If you do not see the results you expect:

It is not a problem with the product! (They all do what we say they do!)

    Your conditions may have been misdiagnosed! (It can happen, even with all the information we provide.) The surface conditions (absorption rate, contaminents, temperatures, etc.) are other than thought. And/or - it was not applied per label instructions! (The instructions are designed to overcome items 1 and 2 above, and overcome job conditions of which you might not be aware.)

When you read all the health and safety warnings, you will see we have done our best to make you think about working with any chemicals from any manufacturer. Even household cleaners purchased in supermarkets (many with more hazardous ingredients than we use due to cost factors) should be used with common sense and awareness. People have been injured by not knowing you can create poisonous gases by mixing chlorine bleach with some cleaning products. One of the many criteria involved in Aldon products is that all our products will be used with any other of our products and no normal combination of usage events should be hazardous. Nevertheless, use common sense and don't be in a hurry. Let each step prove itself satisfactorily before proceeding to the next.
