That's Awesome!!

I would consider that one cut a prepping cut and would have then consider following though with progressive abrasives to a desired finish.

I think leaving the surface like that may give them a floor that is susceptible to staining and or soiling.

I would have them consider using a 120 metal and then make a transition to resin diamonds and finish with DIP'S.

Also there is a densifier for limestone that works quite well-making the stone harder and less porous.

I think the metals should outlast the job-

A couple of things- while these metals will usually stand up to limestone well-we keep a pair of calipers around and gauge the wear so we can know what to expect(this way we can bill or charge for excessive wear) from any soft type of material.

Over the years I have learned much in regard to the wear of abrasives. I have watched enough diamonds disappear before my very eyes for various reasons.

In many cases it wasn't even the make of the diamonds. It was user error in most cases,we just used the wrong diamonds for a particular material or job.

Again an important reason to do mock ups on tricky/techinal jobs-!

With concrete the rule of thumb is to gauge the PSI of the material being worked on.

We use a schmidt hammer to test the surface-not a 100% accurate but its the best method we found-

When working on soft concrete we use hard metal bond diamonds so the diamonds will wear better and cut better as well. When working on a harder concrete surface we will switch to a softer bond diamond which allows us longer diamond life and better cutting ability.

When we do granite grinding we use a very soft bond metal which will cut the granite like butter-breaking the surface and giving us a nice clean cut. These same rules can be used on softer stones as well. We hope to be selling different type hardness metal bond diamonds for stone in the future.

At present we are consulting and selling specific types of metal bond diamonds for larger jobs. (we haven't put them on the site yet)

These diamonds are all magnetic and paired with special plates for planetary and or rotary machines.

Stu,

We completed a test area on this floor, using a set of 4 70 grit metals that we purchased from MB Stone some time ago. They did a great job of cutting the floor flat within a relatively short period of time. The lippage varies significantly from slab to slab. Sanded grout. The floor is about 400 sq ft. Customer is happy with the look of the floor, simply using this one step.

Should we expect these metal discs to outlast this job?

Thanks for the insight.

Give us more info
Sanded grout?
Honed finish I presume?
How high is the lippage
Dime or nickel height?
How large is the floor

An installer sent these pictures to me. The homeowner already had a limestone floor inside the living room that was pretty flat. During a recent kitchen remodel, they installed Oklahoma limestone. You can see the transition of the old and new floor in the first picture. I've never flattened a limestone floor like this. Looking for some guidance. Thanks.
