1. Inspection labels: The product packaging box should have the factory name, factory address, product name, after-sales service telephone number, specifications, quantity, trademark, production date and implemented standards. For porcelain tiles, it is required Check the CCC certification mark and choose products with radionuclides that meet Class A requirements for ceramic tiles used in interior design and decoration.

2. Take a closer look at the appearance: the glaze of good quality ceramic tiles should be smooth and delicate, the gloss glaze should be crystal clear and shiny, and the matte glaze should be soft and comfortable. Under sufficient natural light or fluorescent lighting, if the brick is placed 1 meter away and observed vertically, no obvious glaze defects should be visible. Patterned bricks should have delicate color patterns and other defects. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.

3. Weigh the weight: Weigh the weight of the ceramic tiles. Generally speaking, for ceramic tiles of the same specifications, those with larger weights have lower water absorption and better intrinsic quality.

Notes:

1. Please pay attention to the size and color number indicated on the outer packaging. Use the same size and color number before use. Available in adjacent sizes and colors.

2. Before paving, please wipe off the antifouling agent to reveal the pattern. For many directional patterns, the product should be paved according to the method shown in the diagram to achieve the best decorative effect.

3. Before paving, apply cement mortar to the ground or wall, and mark the line according to the size of the bricks. When marking, leave a 3-5mm mortar joint to prevent the adhesive from interfacing with the bricks. Inconsistent body expansion coefficients may lead to adverse consequences.

4. It is recommended to use 525# cement slurry or a mixture of cement and tile adhesive before paving. It is not necessary to soak the bricks before laying them.
