Tile manufacturer

Interior wall tiles are a type of ceramic tiles, primarily used for interior wall decoration. They consist of three parts: the body, the underglaze layer, and the glaze layer. The water absorption rate of the body is generally around 10-18%. The weight of the underglaze applied is 40-60 grams, while the top glaze is 90-160 grams. In general, the higher the firing temperature, the greater the weight of the top glaze, 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. Hollow spots are permissible at the edges of tiles, but no more than three hollow 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' facades must be within 3mm of verticality; otherwise, they are not qualified.

3. The standard requirement for flatness is that the tiles must not exceed a deviation of 2mm. Additionally, the height difference between adjacent tiles should not exceed 0.5mm. Tiles exceeding the tolerance are considered不合格, and we can request their removal and re-laying.

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, measuring the tile joint levelness and verticality should be done before applying the grout, as the grout can cover up imperfections, making it difficult for us to measure later.
