Rule of thumb is that you shouldn't grind flush a floor that has sanded grout because when you done your grout lines are flush with the tile and your higher grit diamonds will pull sand from the sanded grout and when that sand gets under your diamonds instead of polishing you will be scratching the floor and and up with polished floor with random scratches allover. also if you float the floor with non sanded grout and don't rake at least 1/8" of the existing grout then you will have two different grout lines showing in random places. So the answer to your question is that you need to cut the grout lines before grinding float the floor with non sanded grout which will fill your grout lines and create ramps and grind floor flat. If you mix grout right with latex it will be stable and wont pull out from grout lines and you wont have to grout after maybe touch ups here and there but looking at the marble you may open lots of veins and and pull manufacture fill that you will have to fill with epoxy after initial grinding.On Wed, Sep 28, 2016 at 11:03 AM, Richard Middleton <richard@prosteem.com> wrote:I understand what you are saying about ramping grout up for lippage but are you also saying after grinding we will need to re grout all grout joints with non-sanded grout? Sorry everyone. A lot of information I’m trying to take in. Not sure I should take on a job like this right now. May be asking for trouble!

Yes I would only put one weight on the machine, start with 40 grit steel diamond grind to the floor is flat. Then move to the 100 grit steel and then back to 50 grit resin and work your way up to the finish you need. Once the floor is flat, the rest of the grinding / honing grit go back to your normal timing.
Grouting the floor first will make the first cut much easier.

Richard ,
I would recommend you go in and grout the floor ramping the grout on the edges of the lippage. Do not clean up the grout, allow to dry overnight. The grout will allow your diamond to run over the stone on those high spots and will keep the stone form chipping on the edges, plus allow the machine to run somewhat smother over those areas. grind the floor until all the grout is gone and you will end up with a flat floors.
Remember the first grind is the work horse grind , cut the floor flat with the first cut and then every other cut is the same time.
Should you have any questions, let me know.

This is the marble floor with lippage. Home owner had installed twelve years ago with nothing done to it since. They are doing a renovation on the home between now and end of year. Looks like total of 950 square feet. Worst lippage in dining room at 1/8 inch and other places at 1/16 inch. Home will be vacant at time of floor restoration.
Thanks Everyone!

Yes we run 4 diamonds on our machines(they are easy to place 12-3-6-9 o'clock position-but everyone has their own preference from 3 to 6 pieces.
I like Pats idea about grinding a sample floor prior to the first grinding job.

If you have not done lippage removal before. Get a couple boxes of tiles and put them down and try it so you have some practice before you go into a customer's house. I have seen several companies go in and ruined floors because they have no experience with it

Great-I think it is important to become experienced at flattening floors. It isn't for everyone but if you get comfortable doing those types of jobs you can do well with them.

I will be looking at the job tomorrow. Will take a few pics. I was thinking low end at 8.00 a foot. We get average of 4.00 for hone polish seal on most marble. Stu I will get in touch with you or your staff about metals I will need. Thanks everyone for feedback.
Have a Blessed Day!

We grind a good number of Surfaces . For marble, pricing can go up to $10.00 a sq ft but really depends on the job.
I agree with Randy -see what the competition is doing. I also agree with Greg-get experience-research your area-see where you need to be-charge accordingly.
I agree with Randy on using same diamonds as long as they are quality.
It makes a big difference-The first cut of any grinding job is the most important cut-never rush that one.

Make sure your metals are from the same manufacture. I just did a job and first cut was 30 metal by super abrasives. Then went to a 50 metal from another company and proceeded up to 100 resin at that point I noticed the 30’s where still slightly visible. Went back to those same 50 metals and went over again very thorough and still no luck. I went ahead and got the super abrasive 50 metals out even though they where almost used up, and tried them and wipe the 30’s out easily. A lesson learned for me.

My techs like the metals and coppers from Stu for cutting floors. Knocks down lippage with out leaving deep scratch patterns. Use his metals , followed by coppers then onto 120 resins.

Partners, I will be bidding a residential job for lippage on marble floor. Any suggestions on procedures would be helpful. Machines we have are Hawk 17” and 20”. Also pricing ideas would be helpful. Thank you for any input. Have a great weekend.
