Marble Tiles

Interior wall tiles are a type of ceramic tiles, mainly used for indoor wall decoration. They consist of three parts: the body, the base glaze layer, and the surface glaze layer. The water absorption rate of the body is generally around 10-18%. The weight of the base glaze is 40-60 grams, and the surface glaze is 90-160 grams. In general, the higher the firing temperature, the larger the surface glaze weight, resulting in better brightness and a smoother glaze 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 on the surfaces. 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 bathrooms.

2. The standard for verticality is that the verticality of the tile's facade must be within 3mm. 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 them to be removed and re-laid.

4. Tiles' gaps should not exceed 0.5mm in either horizontal or vertical alignment. In fact, any gap over 0.5mm is visible to the naked eye. Additionally, measure the vertical and horizontal alignment of tile gaps before grouting, as the grout can mask them, making it difficult for us to measure later.
