How to use the hardener and polishing cream
1. Initial grinding with metal diamond #16 or #30, depends on the floor hardness.
2. Fine grinding with metal diamond #80, #150, #300 in steps.
3. Polish the floor with resin polishing pads #50, to repair the polishing scratch of metal diamonds.
4. Spray the hardener, keep the ground moist for 2 hours. If the floor absorbs the hardener quickly, please spray again.
5. Fine polishing the floor with resin polishing pads #150, #300, #500.
6. Super fine polishing with resin polishing pads #1000, #2000, #3000.
7. Spray the polishing cream after the super fine polishing #1000-3000. Apply the polishing cream with a heavy-duty brush broom, so the floor will be covered with the liquid evenly. The thinner the better.
After the polishing cream dry, use C8 high speed burnisher and DT021 black buffing pads to finish final polishing.
