How to preserve marbles and granites?

Marbles and granites are elegant, resistant and timeless in any type of environment. These characteristics make the stone often used in architectural and decoration projects, as facades, columns, stairs, floors, fireplaces and countertops. Due to the broad use, they are exposed to different types of substances, which can compromise the useful life and surface of the stone. Therefore, some cares are necessary for the correct conservation and maintenance of marbles and granites.


In certain cases it is recommended to do the waterproofing of the stones to avoid the absorption by the spill of liquids that can cause stains. This practice should be done annually, prolonging its conservation.


This point deserves attention! The execution and installation of projects with marbles and granites should be done by companies or capable professionals. Installation mistakes can compromise the design and durability of the stones in some cases, requiring replacement of parts due to irreversible damages. Besides knowing to work with each stone and their particularities, these companies can also guide the customer about maintenance and protection for each type of stone. The installation of the stones should be the last step of the project, avoiding people’s movement with residues in shoes that may cause scratches on surfaces.

Stains and scratches

Marbles and granites are porous materials and require special attention with liquids on their surface. Liquids as oil, fat, coffee, wine or even water in abundance can compromise irreversible stains and damage the brightness of the stones. In case of a spill, the surface should be cleaned as soon as possible.

In the case of kitchen countertops, avoid using the stones as a cutting board, because it can cause scratches and cuttings. You should also avoid leaving aluminum objects, iron and steel on the surface, because with the passage of time they can rust and spot the material.

Correct cleaning of marbles and granites

Daily cleaning

The daily cleaning can be done just with clean cloth, water and neutral detergent. Then, finalize the process drying the surface with a soft cloth.

Avoid chemical and abrasive products

NEVER clean marbles and granites with bleach, kerosene, solvent, alkaline detergent or any other abrasive chemical product. These products are highly harmful to the maintenance of the stones, because they can cause stains and scratches.

Following these orientations you can keep the natural and elegant appearance of the stones for more time. Check out the marbles and granites from PR Marble and Granite own quarries.

Besides marble and granite from its own quarries, the Group always had as its aim the search for innovative solutions such as the Pietrafina technology, presented to the market in 2010. It is an exclusive cutting system that yields stone plates as thin as 5mm, reducing the weight of the stone by up to 70%, yet significantly increasing its impact strength due to its special structure. This innovation opens a wide array of possibilities of implementation of dimension stone in never before imagined places, such as drawer and wardrobe doors; elevator floors, walls, and ceilings; lampshades, plafonds and lamps; also the employment in the boating industry. Besides, some materials become translucent.

In these 30 years of activity, completed in 2017, the Group has kept as its philosophy to guarantee the trust and credibility of the products and services it offers, reaffirming values such as commitment to the clients, respect to humanity and the environment, and ethics.
