Talked to a few contractors and interior designer. I am being told that buffing blurred granite flooring will not make a lot of difference. At most I will only see 20% more shine. Note that I mentioned buffing not polishing. 1 of the contractor say that they will not be polishing because granite cannot be polished (hard to polish and effort and $ will be wasted because it doesnt justify the cost). I have quotations from ranging from 800 - 2000. The more expensive ones mentioned they add chemicals etc etc so it will cost more. Please share your findings or experience.
