Roger,

The mastercraft machine will work fine, you may add some weight to the first
grind if you're going to flatten the floor. Does the customer want the floor
flat or just honed? There is a difference. If they only want the floor to be
at a honed finish then you do not need to flatten it. Hone the floor with a
400 grit granite diamond, I use the 3 inch Ceramic pads from StoneCare
Central. They are the DI-CP pads call Margie and she know the pads.

Then I would mount the diamonds on a hog hair pad, you can buy a industrial
Velcro from StoneCare Central it comes 4 inches wide and 36 inch long. Cut
this into 3 to 4 inch squares and glue them onto anew hog hair pad. I like
placing 5 diamonds to a 17 inch pad. When attaching the Velcro to the pad
use some super glue, the Velcro has a self adhesive on it the glue just make
it stick better. Let the pad set over night with some weight on it

Your ready to grind if the final result is to achieve a honed finish I would
try starting with a 400 grit granite diamond, NO your marble diamonds will
not work! I would not use any weight on the machine for this process. Once
the honing is complete if you have any picture framing use a honing powder.
This will remove the picture framing and leave the floor at a nice honed
finish. To remove the picture framing you may need to use a 250 honing
powder then follow up with a 400 powder. Then seal the floor

If you have any other questions, please let me know

Subject: [sccpartners] Granite Floor !!!!

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?
Thanks,
Roger
