Due to the fact that the floor and walls of the bathroom come into contact with chemicals that leave stains. These are personal care products, cosmetics, detergents and cleaning products. Therefore, tiles with increased resistance to chemicals should be used in the bathroom..
For wall cladding in the kitchen, you can use tiles with low strength, since the surface of the walls of the kitchen is little exposed to mechanical stress. The tiles must be resistant to chemicals and have a smooth surface, as food, oils and detergents have an increased chemical effect on tiles. For the kitchen floor, it is recommended to use tiles with particularly high strength mechanical and chemical characteristics, with low porosity and abrasion group 3.
Lobbies and corridors in a residential building
For facing hallways and corridors in residential premises, it is recommended to use tiles of the third and fourth groups of abrasion. Directly at the entrance to the premises, use unglazed ceramic tiles, ceramic granite or natural stone. In addition, tiles with increased surface characteristics such as hardness, resistance to pollutants, chemical influences, and ease of cleaning should be used for flooring hallways and corridors. Consideration must be given to the possible consequences of other parameters such as color, “chromatic structure” or gloss..
With wear of the tile, its ability to get dirty increases, because the top smoothest glazed or vitrified layer of the surface is thinned or abraded and a more porous surface of the tile itself opens. Dirt is conspicuous on light and solid surfaces, but less noticeable on dark or grainy surfaces; scratches are clearly visible on shiny surfaces, etc.
