Interior wall tiles are a type of ceramic tiles, primarily used for indoor wall decoration. They consist of three parts: the body, the underglaze layer, and the top glaze layer. The water absorption rate of the body is generally around 10-18%. The weight of the underglaze 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 glazed surface. Of course, the quality of the glaze also has a significant impact.

Inspection Standards: 1. For wall tiles, there should be no hollow spots. 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 verticality is that the tiles' facade must be within 3mm of being perfectly vertical; otherwise, they are deemed不合格.

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 perpendicularity errors are not allowed to exceed 0.5mm. In fact, any error over 0.5mm is visible to the naked eye. Additionally, measure the tile grout perpendicularity and levelness before applying the sealant, as the sealant can cover up the gaps, making it difficult for us to measure later.
