Got a limestone enquiry with a nice big lippage issue about 3m long where a wall was knocked down and tiles inserted the lippage is 4mm - 5mm. Apart from that problem the floor is pretty badly scratched and generaly hazy as its about 10 years old. Customer wants it polishing back up so the lippage needs taking out etc - is there anything about Jura limestone that is important? As far as I understand it that particular stone is pretty hard as far as limestone goes.
The rest of the floor is flat(ish) lippage of around 1mm in other places old bits 2mm.

Very hard stone as Limestone goes but it's easy to sort and polishes well.

Want me to do a pre inspection on a new Levighetor for you?

Behave Kevin, a Levighetor to sort a 3m long lippage problem?
Sounds like a sledge hammer to crack a walnut to me. : 8

I am behaving the overall floor 90M2 +/- presents with 1-2mm of lippage!  In addition the floor is 10 years old and badly scratched!  Finally the floor has a 3 Metre long strip with what appears to be 4-5mm of lippage!  So what would you sort this out with was my question?

Urmmm, just checked back to the original post...maybe you can help me out here...no sign of 90sqm??
Anyhow, lets assume that the job is 90sqm, with a 3m long lippage problem.
I believe the original poster has in his possesion a Rocky. That machine is more than capable of dealing with the scratches..yes?
I have removed lippage AND repolished using HTC Hy-Brids and Twisters. I am not saying they are by far the best...no, If the customer agrees to cost, maybe Resin or Metal bonded diamonds, but cost is always an issue with most customers.
I am trying to help out Graeme with a cost effective answer that gets him the job.
If Graeme does this sort of work day in day out, buy the Levighetor (or similar) and the full set of diamonds. There is nothing better if money allows

Graeme, the 3m long lippage problem can be reduced with a 50 grit diamond wet pad attached to a variable speed edge polisher and finished, along with the other 90sqm, with your Rocky, or for that matter, any other average machine (even the piece of s--t I bought from Posh Floors)

Potentionally the lippage could stay if the customer won't pay to have it removed.

Rob, milling down lippage that size with resins is only nibbling at it and will create saucing and a inconsistent finish at the final polishing stage.  Although I would not expect this to show too much if twister were been using as clarity and depth of shine are not their strong point.
Couple of different options below of how this floor could be tackeled IMO.

Option 1 would be to flattern the whole floor with a high speed planatry, and this would give the best result by far.

Option 2, flattern floor using 50 grit and 100 grit metal on floor speed.  Then spend ages on 50 grit resin removing impressions of the metals.  I would not advise this with a rockey as mine is now buckled from doing this and doesn't run flat.  This option will get the result but could damage machine and is slow process.

Options 3, remove scratches with resins, avoid big lips where possible to avoid smashing up resin Diamonds,  in between 200 and 400 grit diamond stage, use a320 honing powder to eliminate picture framing and also detail by hand with hand pad as required.  Cheaper option if customer won't pay for lips to be removed and polish at 800 to achieve decent shine and clairty.  Some people would use a crystalizer to hide a multitude of sins at this stage but I would not recommend that

Martin, I am just speaking from experience and trying to help Graeme get the job, however, if the customer agrees, I can see your solution working.

[Graeme Smith]

Thanks all going back when the man in question is in only spoke to his wife there is over 90m2 of this and its not in good condition and its not just a 4-5mm step a 'strip' of tile has been inserted where a wall no longer exists. So that is raised up and wants knocking flat. Interesting thing is the initial enquiry was I need my floor cleaning its not polished - its scratched up all over and is a polished tile - or was. He was a price per m2 over the phone

When you say the Rocky is buckled I assume you mean it is twisted
On the drive knuckle?

Hi Kevin

yes the drive knuckle i presume is slightly twisted, when you spin the drive plate you can see it moves in closer to the metal rim in one part, so it hops a little now when running it.

Ive ran it on one of my test floors and many others with loads of weight added, plus huge lippage when testing a couple of different pad systems.  I've done everything to it, that you explained its not suitable for, when I purchased it.  Maybe secretly i'm trying to break it so I purchase a levi, but its holding up really well to the abuse. its still completely fine to use.  just wouldn't advise it for lippage removal, like you explained to me when I purchased it.     

[Kev Martin]

They take some battering but the Drive Knuckle is connected straight to the gearbox housing. I will contact Klindex Technical tomorrow about it for you!
