Interior wall tiles are a type of ceramic tile, primarily used for indoor wall decoration. They consist of three parts: the body, the bottom glaze layer, and the top glaze layer. The water absorption rate of the body is generally around 10-18%. The weight of the bottom glaze applied is 40-60 grams, while the top glaze is 90-160 grams. In general, the higher the firing temperature, the greater the top glaze weight, resulting in better brightness and a smoother surface for the tile. Of course, the quality of the glaze material also has a significant impact.

Inspection Standards: 1. For wall tiles, there should be no hollow spots on the surface. Hollow spots are permissible at the edges of tiles, but no more than three such spots are allowed in a single room. You can use this standard to inspect the wall tiles in our indoor kitchen and bathroom.

2. The standard for perpendicularity is that the tile's face must be within 3mm of perpendicular. Otherwise, it is not qualified.

3. The standard requirement for flatness is that the tiles must not exceed a 2mm deviation in flatness, and the height difference between adjacent tiles should not exceed 0.5mm. Tiles with excessive deviation are considered不合格, and we can request them to be removed and re-laid.

4. Tile joint levelness, whether horizontal or vertical, must not exceed 0.5mm. In fact, any deviation over 0.5mm is visible to the naked eye. Additionally, measure the tile joint levelness and verticality before applying the grout, as the grout can cover up discrepancies, making it difficult for us to measure later.
