Keep your eyes on the surface of the tile carefully to see if there are any surface defects such as black spots, bubbles, pinholes, cracks, scratches, colored spots, missing edges and corners on the surface of the tile! Don't choose those with too many defects. In addition, you should check the brand mark. No matter what brand the product is, the blank should have the brand mark of the ceramic tile. Check the trademark mark of the blank. The blank of the product produced by the regular manufacturer has a clear product trademark mark. If it is not or is particularly vague, it is recommended to choose carefully!

2. Weigh the tiles:

When choosing tiles, you should put the tiles in your hand to try the weight and feel of the tiles. For the same specification products, the tiles with good quality and high density feel heavier, whereas the products with inferior quality feel lighter.

3. Tap tiles to listen to the sound:

By tapping tiles and listening to the sound, the quality of tiles can be identified. Here are two aspects: kitchen and bathroom tiles and vitrified tiles.

tapping method: wall tiles or small-sized tiles

Generally, one hand and five fingers are used to separate the tiles, and the other hand is used to tap the face of the tiles. If the sound is metallic, the quality of the tiles is better; if there is no metallic sound, the quality of the tiles is worse!

large floor tile: lift one side of the tile with one hand and tap the middle of the tile with the upper part of the palm of the other hand. If the sound is rich and the echo is as long as the sound of tapping a bronze bell, the ceramic tile has a high degree of porcelain, strong wear resistance, high flexural strength, low water absorption and is not easy to be polluted. If the sound is cloudy and there is no echo, the porcelain degree is low (even there are cracks), and the embryo of the tile is not fully calcined.

4. Add water to test the anti-skid degree:

It is actually not entirely appropriate to add water to the brick surface and then step on it to see if it is slippery, because some tiles, especially vitrified tiles, will feel more feet-related after adding water. This principle is somewhat similar to adding water between glasses. If you want to open the glass, it is very difficult because the water squeezes out the air in the middle.
