Madrid
Madrid is a type of Brazilian quartzite known for its elegance and durability. Below are some technical details and characteristics of this natural stone:
General Characteristics:
- Composition: Madrid is predominantly composed of quartz, which gives it great durability and resistance.
- Color: Its coloration is predominantly white, providing a clean and sophisticated look, ideal for various types of environments.
- Texture: It has a fine and homogeneous texture, with a smooth surface that can vary from polished to honed, depending on the chosen finish.
Applications:
- Interior: Due to its neutral and elegant appearance, Madrid is widely used in flooring and wall coverings, kitchen and bathroom countertops, as well as tables and benches.
- Exterior: It is also suitable for exterior applications, such as facades and floors, due to its resistance to weathering and wear.
Extraction Location:
- Madrid quartzite is mainly extracted in the southern region of Bahia, Brazil, highlighting the diversity and quality of Brazilian materials in the global market.
Care and Maintenance:
- Cleaning: To maintain its beauty and integrity, regular cleaning with water and neutral soap is recommended. Avoid abrasive or acidic products that may damage the surface.
- Sealing: The application of a suitable sealant can help protect the surface against stains and facilitate cleaning.
Installation:
- Cutting and Handling: Due to its hardness, cutting Madrid requires appropriate tools and experienced professionals to ensure a precise finish.
- Fixation: Installation should be carried out by qualified professionals using specific mortars and adhesives for natural stones, ensuring durability and safety.
Technical Analysis:
- Geological Classification: Madrid is classified as a quartzite, a type of metamorphic rock formed from the recrystallization of sandstone.
- Hardness: It has high hardness (around 7 on the Mohs scale), making it resistant to scratches and abrasions

Composition
Surface Finishings
Polished
It is the “shiny” surface that results in the plate when receiving the complete finish, that is, until the last grain. Depending on its composition, the polished material may have a higher or lower brightness intensity.
Brushed
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Different brushing models can be executed, with greater roughness, medium and few.
Soft Leather
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Carried out with a brush of low roughness, which gives it a lightly textured look like fabric.
Flamed
It is the resultant surface in the plate when it receives heat treatment (burned with torch specially developed for the function) that takes out small flakes of the same, making the surface slightly irregular producing the impression that it is rustic.
Honed
It is the resultant surface on the sheet when receiving abrasive grinding wheels up to the grain 120. This grain defines the surface finish limit either as anti-slip or even for the application of resin and subsequent polishing.
Leather Finish
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Depending on the type of brushes used you can still reproduce in some materials a surface with a design similar to natural leather.
