What is travertine?

Travertine is very common in constructions and finishing for being a noble, elegant, and timeless option. Travertine is a beige and natural calcareous stone composed by calcite, aragonite, and limonite. There are little cavities and veins that remind branches and leaves.

Types of travertine

The most popular types are from Italy, such as Roman, Navona, Classic, Tuscan, among others. In Brazil, the two most commonly used types are Roman and Navona, both imported from Italy and other places in the world.

The main difference between them is the color and intensity of the veins.


Although beige is its natural color, travertine can be found in different colors and finishing. These aspects make the difference when you choose the material for your project. Coming up next you will see 4 different finishing available in the market:

Rough or natural: It’s the way the stone comes from the nature. In other words, the marble is just sawn. It is very common in wall coatings for presenting an exceptional beauty.

Roman Travertine - Rough or natural

Plastered: It is made applying a resin in the stone that covers the pores on the surface. This finishing can be combined with the levigate or polished type.

Roman Travertine - Plastered

Levigate: It has an opaque and smooth aspect that keeps the natural color of the stone. It can be applied in different ways in external and internal environments.

Recommendations for use

Since it is a beautiful and sophisticated material, travertine has a greater value compared to other coatings. It is mostly indicated to internal environments such as fireplaces, sills, table top, countertops, panels, walls, footers, and floors.

It’s worth pointing out the importance of waterproofing the stone to preserve the characteristics of this calcareous stone. Without the correct waterproofing, the high humidity or chemical agents can damage the travertine over time. The cleaning can be done with cloth, neutral detergent, and water.

Quartzite is a metamorphic natural stone essentially composed by quartzite. In general, it is formed sedimentary rocks and has high resistance to chemical and physical weathering.

In construction, its applicability is vast, because it has elegant visual characteristics like marbles, but it has high resistance like granites. For this reason, it can be applied from kitchen countertops to decorative panels. Since it is a hard material and, therefore, with a higher production cost, it has a more expressive commercial value when compared with other stones. It does not require waterproof and it can be used both in internal and external areas.

What is the difference between marble and granite?

A frequently question that comes up when people look for kitchen countertops or floor and wall covering is about which type of stone should be used: marble or granite? It’s common the confusion between these two terms. Although both are natural stones, each one has their own different technical features. On this article, you will see the difference between marble and granite.

The first difference is the composition of each stone. Marble is a metamorphic stone of calcareous origin and its color varies depending on the mineral present on its composition. It can be predominantly white, grayish, cream coloring with dark veins, greenish or yet predominantly black.

The term metamorphic stone is used for marble because at first it was a common calcareous, but then it went through by physical and chemical transformations due to high temperatures and pressure inside the Earth.

Granite, on the other hand, is composed by quartzite, feldspar and mica. It’s harder and stronger than marble, and there are more colors because of the distribution of its internal minerals. This composition makes granite to have a “glossy” appearance when compared to the uniform and soft appearance of the marble.

Marble and granite application

Since granite is harder than marble, it’s also more resistant. These characteristics make granite the most used in kitchen countertops or laundry rooms, because in the past it was better known for being more resistant to scratches and stains caused by using sharp knives or liquid spills. However, nowadays the stone market has specific products that, when used properly, allow the use of marble in wet areas like kitchens and bathrooms, ensuring more resistance against scratches, absorption of liquids and corrosions.

Both marble and granite cleaning is easy and simple. Just use a wet cloth with neutral detergent when necessary.


For projects with marble, it’s recommended to seal it up once or twice a year. In the case of granite, it can be done about once every two years. However, the maintenance period may vary according to the use. It’s always important to follow the manufacturer’s recommendations for a better use of the product.
