- Safety Glasses
- Work Table
- Cleaning towels
- A complete set of 4 Inch wet diamond polishing pads (Grit 50, 100, 200, 400, 800, 1500 and 3000 grits)
- Wet polisher or grinder
- Marble sealer
Step 1: Clamp the Marble Slab on Work Table
Place the marble tile or slab on a work table, and clamp it secured to ensure it doesn't move while grinding or polishing. If the marble is very porous it is recommended to mask it with a masking tape.
Step 2: Prepare for Marble Polishing With Polishing Pads
Carefully look on the marble slab edges. A profiled or saw cur edge may have some sharp and heavy scratches. Smaller grit sizes (50, 100, 200) are perfect to remove the heavy scratches and higher grit sizes (1500, 3000) are suitable to achieve shiny finishing.
Step 3: Attach Polishing Pads & Backing Pads to Wet Polisher , Start Polishing
Attach the backing pads to wet polisher, ensure it is switched off before attaching it. Now you can begin the polishing process, open the diamond marble polishing kit and start with grit 50 polishing pad. Attach 50 grits to the velcro of backing pad slowly open water flow for wet polisher. Start polisher at low rpm and start polishing the marble edge with side-to-side motion, not more than four or five times. With lower grits, too many iteration can grind more than needed without adding any value to polishing finish.
Step 4: Review Polishing Finish Before Moving to Next Grit
After repeating the process with other small sizes grits, you can find a better smooth surface that are free from all saw marks, old sealant or wax. Use the grinder initially as low speed and as needed increase its speed slowly for faster polishing suitable for specific stone.
Step 5: Move to Next Higher Grit for Marble Polishing
Ensure every single part of surface is polished with the grit before moving to higher grit. Any unpolished area with lower grit will result in sub optimal shine. A good way to ensure every single part of edge is polished is to wipe the edge surface with gently squeezed wet cleaning towel, and polish dry. The heat will evaporate the water where it is already polished. Ensure entire water evaporates then perform one more round of wet polishing. Move to the very next higher grit once the entire surface is polished.
Step 6: Polish Marble Till Grit 3000 Diamond Polishing Pads
Continue and repeat the processes with diamond marble polishing kit from lower grits to higher grit until you get your desired finish. Make sure that you have used grits from lower to higher, apply gradually all the grits 50, 100, 200, 400, 800, 1500 and 3000 grits. Don’t use more than the double grits from the first diamond marble polishing pads. Maintain the regularity to using the polishing pads.
Step 7: Follow All Step Correctly, Here Is Your Polished Marble
Use one by one pad until the polish starts to shine accurately. Then, vacuum the area as needed to remove any debris. You would find good shine at grit 800, and as you progress to grit 1500 and 3000 it will start getting mirror like finish.
