How to make the yin-yang angle of exterior wall tiles

traditional technology: 45 chamfering for external angle treatment: before or in the process of external wall tile sticking, the construction workers cut a certain number of tiles with a certain specification at a 45 angle as needed. When sticking, two adjacent tiles are butted at the external corner to form a right angle, which is shaped like a figure of eight, also called the figure of eight butt joint treatment. This is also the appropriate construction practice clearly stated in the Construction Code (GB5327-21). This treatment method makes the external angle lines uniform and beautiful, but it is time-consuming to cut at a 45 angle. And because the brick material is brittle, small gaps are easy to appear when cutting; If it is not handled well, there may be defects such as different width of the external angle and uneven up and down. In addition, it is easy to seep water in the joint, and if the plastering foundation of the external wall cracks, it may cause quality problems such as external wall watering. When cutting at a 45-degree angle, the tiles to be cut are soaked in water for 1-2 days in advance, which can improve the defect that small gaps are easy to appear during cutting.
