Natural stone maintenance

What should you know about natural stone maintenance?

Natural stones are among the most beautiful, precious and durable building materials. This is why we select them for many projects, from floors and walls, to delicate but spectacular ornaments and luxury finishes.

Where does the need for maintenance procedures come from?

Despite the fact that these are robust materials (marble and travertine less), which apparently should last forever, in reality, all materials have a certain sensitivity to:

  • Weather;
  • Wear;
  • Detergents;
  • Dirt;
  • Acids;
  • Fats, etc.

Prior to use, each surface must be subjected to specific operations to preserve its appearance and value. Basically, the plates can be scratched, stained, soiled or they can absorb the liquids they come into contact with, actions conditioned by:

  • Composition (marble and travertine have a calcareous base, and granite has silicon oxides);
  • Porosity (travertine is the most porous, followed by marble and then comes granite).

How can we preserve the characteristics of natural stones?

At the request of clients or architects involved in various construction projects, we deal with the conservation treatments of natural stones. Depending on the case, it can be about blasting, waxing, polishing, etc.

The type of treatment applied depends to a large extent on:

  • The quality of the raw material (marble, granite, travertine plates can come with various structures, textures and compositions);
  • Use purposes (for interior / exterior, floor / kitchen counter, etc.);

Subsequently, after proper treatment and use, the natural stone must be properly maintained. In this respect, it is necessary for the beneficiaries to pay particular attention to the measures of protection and conservation of the properties of the included materials.

What are the procedures for the maintenance of natural stone surfaces?

Whether you are installing an outdoor pavement, a living room floor or a kitchen countertop, the natural stone must be treated:

  • On the surface, for removing dirt, stains, etc .;
  • In depth, to restore the original features.

Sometimes, the simple intervention of neutral, totally non-aggressive washing solutions should be enough, other times there is a necessity of using specific products for each type of stone.

In general, whatever the requirements, the care measures consist of:

  • Frequent maintenance of waxed or polished surfaces;
  • Removal of traces of soot, paint, silicone, cement, limestone, rust, etc .;
  • Refreshing the initial appearance (beauty, brightness, etc.);
  • Protection against stains of oil, moisture and any kind of dirt or deposits.

What are the basic rules for their maintenance?

By respecting the following indications, as well as the recommendations of the initial technical package, we assure you that whatever the work with marble, granite or travertine, the natural stone will retain its full characteristics. In addition, we cover the work with a two-decade warranty.

1. Frequent operations

Daily maintenance favors the preservation of the original properties. The first thing that users have to do is to protect them from dirt and dust with the help of a vacuum cleaner, a brush or broom.

The next step is to clean the plates by simply using a soap / detergent solution diluted in warm water. Neutral soaps (for laundry) or special for natural stones are the most suitable (fulfill the role of antibacterial and degreasing).

To remove residues and detergent, rinsing with a soft, well-moistened cloth or a mop (in the case of floors) is sufficient.

These tips are especially useful for interior projects, when marble, granite and travertine surfaces are exposed to heavy traffic and constant wear & tear. But they are not sufficient if the surfaces come into contact with corrosive or staining substances.

2. Occasional operations

The procedures of this category can be performed monthly, annually or whenever there is an emergency (exposure to moisture, staining, erosion, etc.). Made on time and correctly, they can save the characteristics of natural stones.

Particularly useful are the treatments that influence the natural brightness, refreshing it, such as those of polishing or crystallization. BrownStone specialists are trained in handling these procedures.

For example, the polishing of marble and travertine is done by using acid-based chemicals, while granite is polished by mechanical abrasion.

What products are incompatible with natural stone?

Generally, for the care of marble, travertine and granite surfaces, alkaline products with a basic (pH less than 7) or neutral (pH = 7) composition are indicated. Among the “friendliest” we can mention ammonia (liquid solution), bicarbonate, soaps and neutral detergents (for example, marsilian soap for clothes).

On the other hand, from the group of “enemies” (they can lead to surface corrosion and permanent damage), are:

a. Acidic products

This is the category where the substances based on hydrochloric, sulfuric and hydrofluoric acid enter, mainly because of their opaque and corrosive effect. These can result in loss of natural gloss, alteration of texture and unwanted coloration.

b. Distorted alcohol

Having an acid pH (the value is between 5 and 6), it can affect the brightness and favor the erosion of the surfaces. This is the reason why the use of detergents and solutions which contain it will be avoided.

c. Anti-lime products

Due to the decrusting action, oriented towards the removal of limestone deposits, these substances are not considered compatible with the natural stones made entirely of limestone (marble, travertine).
