There are several types of decorative stone. Each of them can be used in external and interior finish. Artificial material has several advantages before natural: it is simpler in processing and mounting, its cost is much lower.
1. Thanks to special characteristics of decorative stone, with its help it is possible to execute both internal, and external finishing. The facade or interior decorated by means of this material find originality and presentableness. The decorative stone can be both artificial, and natural. Natural has the big weight and higher cost. As artificial externally malootlichy from natural, but is much cheaper than it, most of buyers gives preference to it.
2. There are several types of decorative stone: marble, cobble-stone, limestone, slate, sandstone and granite. In the choice of this finishing material it is necessary to consider complexity of its laying first of all. It is the simplest to work with sandstone. It is easily pasted, thanks to close to the correct forms and does not demand for mounting of the special equipment.
3. For finishing by means of marble or granite tools will be necessary for cutting of stone. Therefore if it is decided to buy these breeds, it is better to stop the choice on imitation. The artificial stone is made of plaster, by clays, sand and concrete. It is quite simple to saw all these materials by means of the normal Bulgarian with the disk intended for works with stone or concrete. Therefore mounting of finishing will be less labor-consuming.
4. Choosing stones, it is necessary to pay attention to their exterior. It is necessary to consider availability of color impregnations, modulations and shades. All this will create the contrasts so important for high-quality beautiful finishing. If the natural decorative stone has few shades, the wall will look quite sad.
5. The second important point – form of stones. It is better to choose those which have more flat edges. It will give the chance to strongly paste material to surface. If on stones there are a lot of outgrowths or acute-angled ledges, for mounting it will be required to finish each of them manually. It considerably will complicate work and will increase its terms.
6. At the seller it is necessary to take an interest about what water-repellent material properties. If they low, it is required to apply protecting cover in the form of several layers of waterproof varnish on stones. It will involve additional costs. If in production of artificial stone clay was used mainly, the frost resistance of such material is doubtful. Therefore for external finishing it is better to choose natural. Products at the heart of which haydite or plaster differ in high hygroscopicity. This material will demand more thorough protection against moisture influence.
