What are the detailed steps and techniques for grooving the back of the marble and fixing the hanging wire?

The detailed steps and techniques for grooving the back of the marble and fixing the hanging wire are as follows:

Preparation: First, the marble needs to be placed steadily to ensure that its position is accurate. Before grooving, you can use paper adhesive to protect the marble surface to prevent damage to the stone during the grooving process.

Grooving: According to the design requirements, grooves of a certain depth and width are cut along the back of the marble. You can use a professional edge trimmer for automated grooving or manual grooving. After the slot is opened, the slot needs to be finely processed to ensure that the slot is smooth and has no sharp angles, and the size of the slot must match the intended hanging wire system.

Install self-tapping threads: Install self-tapping threads in each notch to provide a firm support point so that the marble can be better fixed on the wall. The installation position of self-tapping should be determined according to the size and layout of the stone.

Fixed hanging wire: Since marble is heavier, using copper hanging wire can increase the firmness. Insert copper hanging wires into each notch and make sure they are securely connected. If possible, stainless steel dry hangers can also be used to further strengthen the structure.

Apply a waterproofing agent: Apply a layer of acrylic waterproofing paint to the grooves on the back of the marble to enhance the waterproofing properties of the exterior finish. This step helps protect the wall from moisture.

Inspection and adjustment: After completing all installations, you need to carefully check whether all hanging wires are firm, whether the notches are flat, and whether the waterproof layer is evenly applied. Make adjustments when necessary to ensure the quality and beauty of the entire installation process.
