In order for your work with natural materials to please you with their appearance for a long time and accurately, you need to properly comply with the technology for laying natural stone, in this case sandstone. In the first stage necessary to prepare the very foundation. It may consist of concrete, granite, slag, compacted gravel, asphalt or other material having a solid crystal lattice. The main thing is that the ground was firm and stable, not was prone to deformation. The choice of the base and its size is directly dependent on future loads on the stone itself and from the intersection of the soil. In preparing the base, it is cleared of debris and obstructions, then are submitted marks the level of cladding on the surface, which should correspond to your project. Then proceed to the preparation of cement-sand mortar, which should match the brand the M150.
Immediately after application adhesive solution onto the surface, you need to start laying the stone. Since the installation must be completed prior to the time when the adhesive grasp. Now the big moment – it is laying sandstone for the adhesive solution thickness should be within 2-3 inches. For those areas where increased traffic, that is, areas with high traffic of people used the stone thickness of 2 centimeters. If this is the area where it is assumed use of different techniques, which can include heavy and, in this case the thickness of the stone should be somewhere around 4 inches.
The thinnest stone used for facing facades of buildings and houses, as well as in residential premises. Typically, the thickness is okolo1-2 inches. For more securely attached to the vertical surface of sandstone, using reinforced mesh with cells of 15 to 15 centimeters and a thickness of 4-6 mm rod or drilled holes and insert the valve on the distance between the rod about 50 centimeters over the entire area treated surface. When facing facades of houses and buildings to improve the quality of the glue, it is recommended to add a special construction adhesive, such as Cerezit in our cement-sand mortar. To comply with the technology necessary to dent the stone in a layer of adhesion to the base. The final stage of stone cladding sandstone is the grout joints. When installing pavements, sidewalks and other road surfaces should be to take this very seriously, because this stage is very important. Grout produces a spatula. The distance between blanks should not exceed 1 centimeter. If part of an adhesive solution penetrated the sandstone, it is not recommended to remove it with a damp cloth, because the solution is not completely removed and remains a blur. To avoid this need give him time to dry out somewhere in the 50 per cent. Then delete the drops of solution with a spatula, and wipe the place clean, dry cloth. When the lined surface is completely dry, it should be swept away adhesive residue with a broom and wash running water. Products sandstone is very diverse. There are products made of sandstone, which are high-precision processing. They are more expensive, but this technology allows the liner without seams. Correct choice of material that you need, professional installation, as well as the implementation of all recommendations for operation and maintenance – to keep all these conditions, your veneer of sandstone is always attractive, long-lasting and showy.
