Granite is a hard rock. Its density is 2600 kg / m3. Granite consists of 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 hallmark of the Earth.
The fact that granite is a fairly strong and dense substance makes it possible to use it as a facing material in construction. Just don't believe them.
After all, this natural stone has been used for construction and decoration for thousands of years. Castles and palaces, industrial buildings were decorated with granite, stairs and dishes, decorations and fireplaces were created from it. 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 Escorial Palace, near Madrid. The building is over 450 years old! The myths below are debunked by time itself. It was this that 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 difficult its extraction, the more it costs. Sometimes the stone is mined in hard-to-reach places among the mountains, where there are no really roads. Today the market provides an opportunity to choose an inexpensive granite grade. 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 slabs made of artificial stone. Comparing the cost of granite countertops and similar products made of synthetic materials (Corian, Sileston), one can be surprised. After all, natural stone will be cheaper!
The granite surface must be constantly looked after. Indeed, a granite slab should be looked after, but no more than any other material. If the countertop is made of granite, then it is enough to simply clean its surface. Depending on the properties of granite, it can be treated with a special impregnation if necessary. For example, for the Luna Pearl brand, impregnation is not required at all, but for Madura Gold it is necessary to carry out such a treatment from time to time. The Shivikasky brand is quite porous, it cannot 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. Not all brands need protective impregnation. Some of them have a rather dense structure that prevents anything from penetrating into the stone. For the impregnation to work, it is necessary that it penetrates into the structure of the stone, filling in all the voids and pores. And if they are absent, then impregnation cannot get into the granite structure. It is very simple to understand whether granite needs impregnation. You just need to pour some water on the surface of the stone. And everything will immediately become clear.
Protective impregnation must be applied to the granite every year. No one bothers to treat the surface with a seal every year. But there is no practical sense in this. It is best to use a high quality material for the initial impregnation, which will last 10 years. All protective fluids contain a filler and a resin. Cheaper impregnations contain cheaper components. In addition, there is a smaller percentage of the resins themselves, and a larger percentage of the filler.
Granite surfaces can stain over time. This is not true, because granite is stain resistant. Some grades of granite, moreover, are so dense that they do not even absorb protective impregnation - the stains simply have nowhere to come from. It is generally believed that lighter surfaces are more prone to third-party stains. And if you wish, the stain can be left on any hard surface, regardless of whether it is made of natural or artificial stone.
The stain that has appeared on the granite cannot be removed by any means. If, nevertheless, there was a trouble - a stain on the granite slab, do not despair. Indeed, in most cases, it can be removed with a conventional degreaser or toilet soap solution. How exactly the stain should be removed depends on its type and nature and on the period of its presence on the surface.
If a granite slab is heated, it may crack. Granite is a durable material. It is able to withstand quite high temperatures. If you put a hot frying pan or saucepan on the granite, the tabletop will never crack. So warm dishes will not damage the stone. But in the operating instructions for countertops made of synthetic materials, such as SileStone, Zodiac or Corian, they usually write that you cannot put hot dishes on them. It is strongly recommended to use special stands.
Granite contains harmful bacteria. Many people hesitate to buy granite countertops due to the high content of microorganisms in them. However, studies have shown that granite is much safer compared to other materials. 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 led to the death of dozens of people in Germany. So, granite has nothing to do with it.
Granite is radioactive. Science impartially notes that almost everything around us - soil, air, drinking water, and other building materials (concrete, cement, gypsum), contains more radon than granite. Studies have shown that granite does not pose any health risk. The radiation level near granite averages 25-30 μR / h, while the background rates from local sources are twice as high. There is no danger, but it is better to cover the house with granite from the outside.
Granite countertops must have a seam. This is not the case, granite countertops can be completely seamless. After all, those granite slabs, which serve as the basis for further cutting out countertops from them, can, depending on the type of granite, reach an impressive length of 4 meters. Therefore, if you wish, you can always find a solid worktop of the desired width and length. Usually a good manufacturer tries to match the pattern of the two slabs so that the existing seam is minimally noticeable.
Granite cannot be restored. Potholes sometimes appear on surfaces. This does not happen often, because granite is a hard material. But even if chips have appeared, they can always be eliminated. For this, a painted epoxy resin is used. And if scratches suddenly appear on the granite slab (which is also unlikely), then you can use polishing.
Over time, granite will lose its luster. Again, we said that granite is a fairly hard material. Among those stones that surpass him in this parameter are diamonds. It is due to this fact that a diamond tool is used to polish granite. In ordinary household conditions, objects are low abrasive, which does not make it possible to somehow damage the surface of the stone. Consequently, the shine will remain the same.
Granite and marble are one and the same. These natural stones have some common features. Both can be polished, they are often used as building and decorative materials. But the composition of granite and marble contains completely different minerals. Granite includes quartz, which gives this strength. But marble contains calcite, which leads to the possibility of abrasion and more susceptibility to chips and scratches. Calcite is very rare in granite. And the origin of these stones is different. If granite is an igneous rock, then marble is of metamorphic origin.
