Water absorption rate of tiles
The first thing to pay attention to is the water absorption rate of ceramic tiles in the bathroom. Generally speaking, high-quality tiles have low water absorption, so they can dry quickly. If the tile does not indicate the water absorption rate, you can use tea or water droplets on the back of the tile. After a few minutes, check the spread of the water droplets. The less water is absorbed, it means that the water absorption rate is low and the quality is better. Tiles with high water absorption rate will cause cracks on the surface of the tiles and peeling off of the entire wall and floor tiles after thermal expansion and contraction. The toilets in northern areas with four distinct seasons need to be paid more attention to this problem.
Tile texture density
The purchase of ceramic tiles in the bathroom space has stricter quality requirements for the tiles themselves. When buying tiles, you can observe from the side whether the tile surface is flat and whether there are pinholes of uneven thickness. At the same time, you can tap the tiles to hear whether the sound is crisp. The crisper the sound, the higher the texture density and the better hardness of the tiles. When such tiles are laid in the bathroom, they are not easily damaged, and are also easy to maintain and clean.
The degree of glazing on the brick surface
The current ceramic tiles will be notified to consumers when they are sold Suitable for bathroom space. When purchasing, you can identify it by judging the thickness of the glaze layer on the surface of the tile. Consumers can scratch the surface of the brick with a hard object. If there are scratches, it means insufficient glazing. After the thinner glaze layer on the surface of the tile is polished, the surface of the tile is easy to be stained, difficult to clean, and lacks security. And some unglazed floor tiles are generally not suitable to be laid in a damp and airtight environment, because the pores on the bricks absorb water vapor and cannot disperse, which will also cause mold to appear.
