Granite Floor !!!! Roger Konarski 17 Jun 2010 20:09 EDT

I got a call today on new granite floor insulation; I believe they said it was polished black absolute. They want a hone finished on the floor. The positives are that the floor trim has not been installed. While I can top polish granite with no problem, I have never ground flat a granite floor. I was told it is about 300 sq. ft. I have Mastercraft (that needs to be replaced). I also have a Clarke MP1800, would one of these machines do the job and what type of grinding disc and pads would you possible recommend?
