1. Begin by thoroughly cleaning the stone surface to remove any dirt, dust, or concrete residue from the joints. Use a knife to carefully scrape out any remaining slurry between the stones, then brush and vacuum the area to ensure it is completely clean. Make sure the ground is dry, free of sand, and free from any debris before proceeding.
2. Once the entire surface is clean, address any small cracks or damaged areas using marble adhesive that closely matches the color of the stone. Apply the adhesive to the damaged spots and allow it to dry. Then, use a specialized stone cutting machine to re-cut the joints for uniformity, and fill them with matching marble glue. Ensure the glue is fully dried before moving on to the next step.
3. After the adhesive has dried, use a floor sander to polish the entire surface, paying special attention to the gaps between the stones, wall edges, and any decorative features. This ensures a smooth and even finish. Perform a second round of grinding after reapplying the adhesive, using a stone refurbishing machine with steel grinding discs. Start with coarse discs and gradually move to finer ones—seven stages of grinding and polishing are typically required. The final result should be a flat, smooth, and glossy surface. Finish with a steel wool pad for extra shine. For granite, always use bridge mills and professional grinding discs, avoiding resin discs. During rough grinding, maintain the same number of passes and avoid changing the disc type. Use 60-mesh discs to eliminate height differences, color inconsistencies, and scratches. For fine grinding, continue with the same process without reducing the number of passes.
4. Once the polishing is complete, use a water extraction machine to remove any standing water. Dry the entire surface using a blow dryer, or allow it to air dry naturally if time permits. A completely dry surface is essential for the next steps.
5. Apply a crystalizing solution evenly across the floor, then use a marble polishing machine with a red scouring pad to work the solution into the stone. Sprinkle an equal amount of water along with the syrup and begin grinding. The heat generated during this process helps the crystalizing material bond to the stone surface, creating a mirror-like finish.
6. For large gaps or heavily worn areas, apply a marble protective agent and perform an additional polishing session. This enhances the hardness and durability of the polished surface, ensuring long-lasting results.
7. After the surface achieves a crystal mirror finish, use a vacuum cleaner to remove any residue or moisture. Finally, use a polishing pad to bring the floor to a fully dry and reflective state. If any local damage occurs, perform spot maintenance as needed. This process can be carried out at any time. Once fully cured, the stone surface should meet the desired gloss level—travertine should have a minimum of 60-degree gloss, while granite should reach over 80 degrees. There should be no visible height differences between the stones, and the surface must be perfectly sealed without any leaks.
A magnetic valve is a type of valve that uses an electromagnetic field to control the flow of fluids or gases. It consists of a coil of wire that generates a magnetic field when an electric current flows through it. This magnetic field interacts with a ferromagnetic core, which moves a plunger or armature to open or close the valve. Magnetic valves are commonly used in industrial applications, such as in water treatment plants, chemical processing plants, and HVAC systems. They are also used in medical equipment, such as oxygen concentrators and anesthesia machines. Magnetic valves are known for their high reliability, fast response times, and low power consumption.
