Even if a granite table or a floor or sink made of this stone is naturally considered to be robust, this natural stone also needs regular maintenance – after all, it should look permanently beautiful and shiny. Expensive and noble granite, which wears out in the long run and thereby becomes dull and unsightly, often requires a new cut and sealing. Regular wiping with special cleaning agents will preserve and lastingly improve the natural beauty of the granite. For maintenance, the floor can be rubbed with ammonia and then with floor wax. Outside, strong alkalis (e.g. powder and tabs for the dishwasher) can work wonders with light soiling from dust and moss. Damp salt can help with fresh stains. It is much more difficult to remove greasy stains with wax or oil. In this case, moisture-absorbing powders or special pastes have proven effective. These should act according to the manufacturer’s instructions, wipe them off and repeat them several times. Our cleaning agent concentrate BIOSATIVA\u00ae<\/a> could be used here. This is suitable because it is completely biodegradable. There is no loss of cleaning power.<\/p>\n\n Granites are igneous rocks that are formed from molten rock. The massive and relatively coarsely crystalline igneous rock is rich in feldspars, quartz and dark minerals such as mica. Granite is formed by the solidification of magma (rock melt) within the earth’s crust, mostly at depths of more than two kilometers below the earth’s surface. For this reason, granite is one of the deep rocks. The required quartz content of light minerals for granite must be at least 20 percent to a maximum of 60 percent. In most cases, granites are light-colored rocks. In addition to white, reddish or yellowish colors, there are also multi-colored variants – however, granite is never completely black. This is exactly where granite differs from gabbros or basalts, especially since these do not contain any quartz. This aspect should be taken into account in the natural stone trade, as these stones have nothing to do with granite and are often less robust.<\/p>\n<\/div>\n\n\n\n One of the great advantages of granite can be seen in its robustness. It is not for nothing that expressions such as “hard as granite” or “bite on granite” have become established, referring to the resilience of the rock. Granites can look very different even with the same chemical composition. The color of the minerals and their grain size are mainly responsible for the numerous different variants. Granite is generally medium to coarse grained. It has a relatively uniform appearance, which results from the homogeneous mineral distribution with mostly directionless texture. Its structure is characterized by a direct grain association, with the crystal size usually fluctuating between one and several centimeters. In addition to granites of the same size, in which almost all crystals are of the same size, it is not uncommon for granites of irregular grain or porphyry to occur. In this case the individual crystals – mostly so-called feldspars – are several times larger than the other minerals.<\/p>\n<\/div>\n<\/div>\n\n Our granite sealing achieves a unique long-term effect due to its depth effect, which makes the stone look good in the long term and effectively and permanently protects against all external influences. Due to the lotus effect, water will simply roll off the surface in the future.<\/p>\n\nDefinition and composition<\/h2>\n\n\n\n
