💢 Ceramic Water Absorption Rate (WA) 💢

Impermeable to water and moisture is one of the most important characteristics of good ceramics. The degree of ceramic water absorption is indicated by the abbreviation WA, which stands for Water Absorption. The higher the quality of the tile or ceramic, the lower the degree of water absorption. The porosity of the body of these products causes water to penetrate into them. The penetration of water into ceramics and tiles in the long term, especially in cold regions, causes them to freeze and crack. It is recommended to pay attention to the use of that space when buying ceramic tiles. The use of ceramics with a high degree of water absorption in open spaces such as building facades that are exposed to moisture and water and closed spaces such as toilets and bathrooms is completely unprincipled.

Tiles and ceramics available in the market in terms of Water absorption is divided into four categories:

The first group is tiles and ceramics that absorb more than 7% of their weight. These ceramics are not suitable for open spaces and humid spaces such as bathrooms and toilets. The second group is ceramics and tiles that absorb water between 3 and 7% of their weight. These ceramics also do not have sufficient resistance to water and it is better not to be used in humid environments. The third group are tiles and ceramics that absorb water between 3 and 0.5% of their weight. These ceramics are a good choice for bathrooms and are good ceramics for humid environments. The fourth group is ceramics and tiles whose water absorption rate is less than 0.5% of their weight. These ceramics are almost impermeable to water and are considered the best option for bathrooms, swimming pools and building facades in wet areas. It should be said that porcelain ceramics have the highest resistance against moisture penetration. It is something that should be taken into account when choosing the ceramic for the facade of the building and the floor tile for the yard. Cold-resistant tiles and ceramics usually have a higher manufacturing quality and therefore a higher price. Despite this, they are considered very necessary in order to reduce subsequent costs and have a longer lifespan in cold regions. The main reason for cracks in ceramics in climates with extreme cold and heavy snowfall is usually the use of low-quality products with high water absorption. It should be said that this classification is not very important in choosing the suitable ceramic tiles for interior spaces. It should also be noted that resistant ceramics are usually good thermal insulation and prevent cold from entering the building.
Ceramics and tiles are produced in many different colors and designs. Various minerals such as iron oxide, chromium oxide, cobalt oxide, cobalt carbonate, copper carbonate, etc. are used to produce each of these products. As a result, the color quality of ceramic tiles is very important in choosing it. Also, different colors of ceramics and tiles are suitable for different spaces. For example, white and blue colors are usually used in bathrooms and toilets to create a sense of cleanliness. In general, the bright colors of ceramic tiles make the space look bigger and increase the ambient light. Multi-colored ceramics are also produced in a limited way and are widely used in interior decoration. It should be remembered that high-quality ceramics have a uniform appearance and their designs are very precisely carved.
