is a solid rock. Its density is 2600 kg / m3. Consists of granite from feldspars, quartz and dark-colored minerals. In the structure of the crust of our planet, this substance plays a huge role, it is also called the visiting card of the Earth.
The fact that granite is a fairly strong and dense substance makes it possible to use it as a facing material during construction. But many people are frightened off by the increased radiation background from such a stone. And other myths accompany granite. Just do not believe them.
After all, this natural stone was used for construction and finishing for thousands of years. Castles and palaces, industrial buildings were decorated with granite, from which ladders and dishes, ornaments and fireplaces were created. After all, this material is able to withstand the influence of the environment. Granite is not afraid of snow or rain, temperature or bad air. The stone still retains its original beauty.
The largest building, built of granite, is the palace of Escorial, near Madrid. The building is more than 450 years old! The following myths debunk the time itself. It has proved the practicality of granite and the convenience of working with it.
Granite is an expensive material.
Indeed, granite can be expensive. After all, the less often the material is and the more complex its extraction, the more it costs. Sometimes a stone is mined in hard-to-reach places in the mountains where there are no roads really. Today, the market provides an opportunity to choose an inexpensive brand of granite. These include Santa Cecilia, Verde Labrador, New Venetian Gold, Baltic Brown or Uba Tuba. As a result, the cost of granite slabs can be even less than plates made of artificial stone. Comparing the cost of granite countertops and similar products made of synthetic materials (corian, silestone), you can be surprised. After all, a natural stone will be cheaper!
You have to take care of the granite surface.
Indeed, you have to look after the granite slab, but not more than any other material. If the granite is made top, then it is enough just to clean its surface. Depending on the properties of the granite, it can, if necessary, be treated with a special impregnation. For example, for the brand Luna Pearl, impregnation is not required at all, but for Madura Gold it is necessary to carry out such treatment from time to time. Mark Shivikasky is quite porous, it can not do without impregnation, but Black Galaxy, Verde Maritaka and Volga Blue will do without it.
Any brand of granite needs to be treated with a water repellent.
Protective impregnation is not necessary for all brands. Some of them have a fairly dense structure, which prevents the penetration of something into the stone. In order to impregnate, it is necessary that it penetrate into the structure of the stone, filling all the voids and pores. And if they are absent, then impregnation into the structure of granite can not get. To understand whether granite needs impregnation is very simple. You just need to pour some water on the surface of the stone. And all at once it will become clear.
Protective impregnation should be applied to granite every year.
No one interferes with the surface treatment with a sealer every year. Only here there is no practical sense in this. It is best for the initial impregnation to use a high quality material that will last for 10 years. All protective fluids have a filler and resin in their composition. Lower cost impregnations contain cheaper components. In addition, there is a smaller percentage of resins themselves, and more – a filler.
Granite surfaces may become stained with time.
This is not true, because granite is resistant to the appearance of spots. Some grades of granite are also so dense that they do not absorb even protective impregnation – spots simply can not be taken there. It is generally believed that lighter surfaces are more prone to the appearance of third-party stains. Yes, and if desired, the stain can be left on any hard surface, regardless of whether it is made of natural or artificial stone.
The stain that appears on the granite can not be withdrawn by any means.
If there is still a problem – a stain on the slab of granite, do not despair. After all, in most cases, it can be removed with a conventional degreaser or a solution of toilet soap. How it is necessary to remove a stain depends on its type and nature and on the duration of its presence on the surface.
If the granite slab is heated, it can crack.
Granite is a strong material. He is able to tolerate fairly high temperatures. If the granite put a hot frying pan or pan, then the table top will never crack. So warm cookware does not damage the stone. But in the instructions for the use of table tops made of synthetic materials, such as SileStone, Zodiac or Corian, they usually write that they can not put hot dishes on them. It is recommended to use special stands.
The granite contains harmful bacteria.
Many do not dare to buy granite countertops because of the high content of microorganisms in them. However, conducted studies have shown that granite compared to other materials is much safer. This also applies to E. coli bacteria, which cause intestinal disorders. But this is important to know, especially after an unknown strain of this microorganism has led to the death of dozens of people in Germany. So, granite has nothing to do with it.
Granite is radioactive.
Science notes impartially that practically everything around us – soil, air, drinking water, and other building materials (concrete, cement, gypsum), contain more radon than granite. Studies have shown that granite does not pose any risk to health. The radiation level of granite is on the average 25-30 microR / h, whereas background rates from local sources are twice higher. There is no danger, but it is better to tile the house with granite from the outside.
Granite countertops necessarily have a seam.
This is not so, granite countertops can be completely without a seam. After all, those granite slabs, which serve as a basis for further sawing out tabletops, can, depending on the type of granite, reach an impressive length of 4 meters. Therefore, if you want, you can always find a solid table top with the desired width and length. Usually a good manufacturer tries to pick up a pattern of two plates so that the existing seam is minimally noticeable.
You can not restore the granite.
Potholes sometimes appear on the surfaces. This happens infrequently, because granite is a hard material. But even if the chips have appeared, they can always be eliminated. For this, a colored epoxy resin is used. And if on the granite slab suddenly there were scratches (which is also unlikely), then you can use polishing.
Over time, the granite will lose its luster.
Again, we repeat that granite is a fairly hard material. Among those stones that exceed it in this parameter are diamonds. It is thanks to this fact that a diamond tool is used for polishing granite. In ordinary home conditions, objects are low-abrasive, which does not allow somehow to damage the surface of the stone. Therefore, the shine will remain the same.
Granite and marble are one and the same.
These natural stones have common features. Both can be polished, they are often used as a building and decorative material. But the composition of granite and marble are completely different minerals. Granite includes quartz, which gives this strength. But marble contains calcite, which leads to the possibility of abrasion and greater exposure to chips and scratches. In calcite, calcite is a rarity. And the origin of these stones is different. If granite is a magmatic rock, then marble has a metamorphic origin.
