Bian Xiao, external wall brick quality appraisal method, teaches you six appraisal skills.

1. Drop a few drops of tea juice or water on the back of the ceramic tile, and wait for a few minutes to see the degree of water drop diffusion. No water absorption or small water absorption, the quality is good.

2. Tap on the tile to see if the sound is crisp. The crisper the sound, the higher the porcelain degree, density and hardness.

3. Will there be scratches when scraping tiles with sharp objects? If there are scratches, it means that the glaze is not good and it is easy to slip. After the glazed surface is polished, the dirty brick surface will not be cleaned.

4. The color and chromaticity of ceramic tiles are clear and natural, indicating that the degree of porcelain is high, the chromaticity is unclear and the degree of porcelain is small.

5. When purchasing, observe whether there are pinholes on the surface with naked eyes within one meter. If there are pinholes, it means that the glaze is not completely fused, which is easy to cause dirt accumulation.

6. Warp observation: Check whether the side of the tile is straight with naked eyes. Severe warping will affect the firmness of tiles in the future.

Consumers can identify the purchased exterior wall tiles according to these skills.
