Eric,
How thick was the lippage when you started??? You are using the correct diamond , have you added any weight to your machine?

Subject: Fwd: RE: [sccpartners] Cutting Lippage
I'm using the 3" 40 grit metals from Stone Care Central:

The slurry looks like:
After 24 mins of cutting at 2' x 5' area, we're still left with lippage like:
Lots of water for lubricant. Stone still gets warm to the touch.

>> Hard to see the clarity in the pics but almost looks like a light emperador which would make sense if you are pulling fill out.
>> Many different qualities out there today but if fill is coming out you need to decide how you will refill. How much material are you dislodging?
>> That stone is probably medium hardness so it will take you some time-but being patient and taking your time though the first cut will help you.
>> If the lippage is so bad that you are throwing diamonds it may be a good idea to float those areas with the same grout the tiler used.
>> You could have told the tiler to float the grout out like that on the whole floor except on top of the baseboard-Nextime. You ll be fine-like you said this is school and you will learn a boatload. We all will help you thru it if you need us.
>> If you grouted the machine will run more stable and smooth. If it is too late for that then there are some other methods to control the bouncing but they could add to the time(grind down high edges by hand dry with dust control and hepa vac). You didn't mention that it was throwing off your diamonds so if it isn't then keep moving slowly and listen to the machine. As it becomes quieter the floor is getting flat.
>> Notice when you start a new areas as opposed to a flattened area the clicking of the machine. when that machine gets quiet those areas are close to flat. Make sure that you concentrate and the perimeter of your first grind-also when the floor dries any shiny or dark spots will reveal where the floor isn't flat. You will see this at the corners of the tiles. These areas you can go back over or grind down by hand.
>> Do you your first cut bu working small sections at a time and moving on once there flat. You can always go back over sections.
>> We very rarely use a level to check the floor.
>> Good luck!

We made him cut out the sanded grout. He put back unsanded, with a TEC acrylic additive. Just 500 square... a dining & living room.

Only as we'd already taken off all the shine, the only way to tell was by feel. Most of the floor is smooth, but there are a couple spots where the floor machine bucks as though not flat. When it's still doing that after 3 or 4 twelve minute cuts, I got nervous about going farther. What is the objective standard for knowing that the floor is flat? Straight edge? Laser?

If you needed to you could always run a fiber grit pad (ie,twister,cps,monkey) to deal with frames at the(btwn your 220 and 400 grit resin diamond cuts) edge.Or run honing powder if you needed.
