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 of 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 facade 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 flatness error of 2mm. Additionally, the height difference between adjacent tiles should not exceed 0.5mm. Tiles exceeding the error are considered不合格, and we can request their removal and re-laying.

4. Tile grout levelness or verticality errors are not allowed to exceed 0.5mm. In fact, it's visible to the naked eye if it does. Additionally, measure the tile grout verticality and levelness before applying the decorative grout, as it can cover up imperfections, making it difficult for us to measure later on.
