1. Choose the home market where consumer satisfaction or after-sales service is trustworthy.

2. To shop around, consider the same style, the same brand of goods, comprehensive consideration from the quality, price, service and other aspects.

3. Ask the merchant for product environmental protection material test report

4. Appearance quality According to national standards, ceramic tiles are divided into four grades: excellent grade, first grade, second grade, and others. The appearance quality can be judged by the appearance. The appearance always has:

(1) Color difference: It is important that there is no difference between the bricks and bricks of the same name.

(2) Size: The lengths of the corresponding sides of the bricks of the same product name and bricks are inconsistent and are small and large.

(3) Size head: The length of the same brick on the opposite side is inconsistent.

(4) deformation: If the edge is not straight, warping and so on.

(5) Defective surface quality, such as uneven glazes, pinholes, dregs, falling angles, etc.

5. Water Absorption: Tiles with high quality have low water absorption. Tiles with higher water absorption are more likely to absorb water. After shrinkage and thermal expansion, cracks on the surface of the ceramic tile and peeling of the entire tile are caused. If the water absorption rate of the tile is not specified, tea or water droplets can be used on the back of the tile for several minutes. After seeing the degree of diffusion of water droplets, the less water absorption, the lower the water absorption rate and the better the quality.

6. Porcelain degree: can tap the tile to hear the sound is crisp, the more brittle the sound, that is, the texture of the tile density is high, the hardness is better. And can scratch the brick surface with a hard object, if there is a scratch, it means that lack of glazing, after the surface of the glaze polished, the brick surface is easy to hide, it is difficult to clean.

7. Color pattern: The color pattern can be decided according to personal preference. When choosing, pay attention to the matching of the color tone of the tile and the matching of single flower and group flower.

8. The name, specification, quantity, price, and amount of the tiles must be specified on the invoice and contract.

9. Understand the names, addresses, contacts, and telephone numbers of the organizers and manufacturers so that the quality can always be solved in time.
