Marble and granite: discover the differences and the most suitable uses
Marble and granite are among the most used stones as floor and wall coverings and in countertops. Very durable, these stones add sophistication to the environments in which they are applied.
It is common, however, that the two are confused, and this, in addition to a difference in appearance, can cause the characteristics of each stone not to be explored according to its use.
In this post, you will learn more about marble and granite, understand the differences between them and also know some applications of these rocks. Follow up!
Differences between difference between granite and marble
Marble and granite are not so similar, mainly because they have, in their composition, different minerals, which give them unique aspects of shine and texture.
However, they are often confused because they are basically used for the same purpose. It is important, however, to know what their peculiarities are, so that they can be used in the best possible way.
Marble is a rock formed from limestone (the same one that appears in cement and lime), which, subjected to different conditions of temperature and pressure, had its structure modified.
Granite, on the other hand, is made up of different minerals, such as feldspar, quartz and mica, the latter two being responsible for giving it a certain shine.
Characteristics and indications for use
The two decorative stones come in different types, and prices often vary. However, to choose the one that will be ideal for your project, it is important to evaluate aspects other than price, such as the purpose of the piece in the environment – bench or floor, for example – and the characteristics of each one of them, as we will show. Follow:
This rock usually has a higher cost than granite. But the higher value does not mean that the rock is more resistant.
On the contrary, marble, due to its composition, can be more sensitive to the appearance of stains and even corrosion by chemical products, thus being indicated for more specific uses.
Therefore, marble is ideal for floors and walls in urban environments, bathroom countertops or in other areas of the house that do not require constant use of chemicals or agents that can mark the stone.
In terms of appearance, this rock tends to have lighter tones and a characteristic pattern. In general, clear and smooth marbles are rarer and therefore more expensive.
Granite, on the other hand, is much more resistant, being indicated for floors and countertops in general, even in places more exposed to dirt and chemicals, such as bathroom floors, outdoor floors or kitchen countertops .
The appearance of granite is grainy and sometimes, depending on its composition, has bright spots. Unlike marble, the darker, the more expensive this rock is; in this case, it will have a more uniform appearance, with light spots of shine.
Most common finishes
Finally, there are finishes made on the surface of the stones, which can increase their durability. See some:
- rough: the rock does not undergo any finishing work, relying only on its natural characteristics to protect itself from external agents;
- flamed: a jet of fire gives the stone a rough texture, making it ideal for outdoor floors , for example, for its non-slip characteristic;
- Sandblasted: Sandblasting gives marble or granite an opaque appearance;
- Polished: the stone gains a shiny and smooth appearance, but it is also very slippery, making it ideal for use in dry areas or countertops.
- Resin: the application of resin completes the pores that may exist in the stone, giving a superior finish and also more protection against stains. As it results in a very smooth piece, it is also preferable to use it on dry surfaces, to reduce the risk of slipping.
The edges of the stones that will be used on tops and countertops can also be cut according to the taste of those who will purchase them, and can be more rounded or in straight lines.
Whatever your choice, marble and granite are two decorative stones that will bring nobility and practicality to your apartment.
