Set of Stadea Series Ultra D, 7 diamond polishing pads one each for grit 50, 100, 200, 400, 800, 1500, 3000 with 4" semi flexible rubber backing pad. Stadea Series Ultra D diamond polishing pads set is designed for hard stone polishing, and are very effective on Granite, Quartz surfaces and edges. They are equally effective on Marble surfaces as well. The lower grits upto 200 can be used for dry grinding. For best polishing results, use them wet. 

How to Polish Granite Concrete Marble Stone using Stadea dry diamond pads

1. Always wear protection for eyes, nose, hands, safety glass, gloves and apron. Never use high speed grinder and exceed rated RPM.
2. Secure/fasten the stone, it should not slide while polishing.
3. Attach velcro backer pad and polishing pads to polisher evenly else it may wobble. Start polishing with grit 50 at low rpm, adjust rpm as needed. Verify the entire polished stone surface has same level of smoothness before moving to next grit. If not, continue polishing with same grit. Generally above grit 400 grit surface is scratch free.
4. Repeat step 3, for each higher grit one by one starting grit 50 till 3000. Don't skip any grit in between. Most of the stone will show shine starting grit 800. If one still sees scratches beyond grit 800 and 1500, it is a sign that step 3 is not followed correctly in lower grits.
