Stuart,

With hair line crack with any stone they are tough to repair. In most cases the cracks are noticeable because they have trapped dirt within them. There are a couple ways to attack this.

1.        go in and do a good cleaning of the crack using an alkaline based stripper . Get as clean as possible, then use acetone to flush out the crack and dry the surface if the cracks are open enough use a professional dental pick that can be purchased from most Army Surplus store. Use the pick to scrape out the crack and then flush with acetone again. The crack should be clean and ready to fill. Use a flowing fill ( polyester resin ) and fill the cracks. The flowing material will go into these voids and the fills is complete. Allow the product to harden and remove any excess material by either using a single edge razor blade holding the blade straight up and down and scrape off the excess or hone off the excess materials.

2.        The second way is to use a small dermal tool and open the crack slightly and then clean in the same process as above and use either flowing or knife grade filler. This is my second choice of repair and my least favorite

John: since 1996 when we bought our first marble machines,because of the ease and reliability of a flat ground ,resin honed and polished finish, I have never had the opportunity to hone with powders, it was never a requirement for me.Look i dont want to waste your time, I have to assume on a job like this it would have to cost at minimum .50 per sq ft per step, if we started 50 honing powder, that's 6 steps to finish at least 3 bux a ft, plus travel. Job is near Ocala, but 3 a sq ft for them is out of their budget, would you be interested in a fair split where i bring my body and equiptment,compensate you fairly for experence? how quickly compaired to diamonds do powders work,what would be an approximate cost per ft for the powders?

Scott,

 

if the lippage is bad you could actually hone the floor using honing powders. Them come in grits as low as 50, it wouldn’t remove the lippage but would remove most of the scratches except for those real deep one. Then hone the floors with powders up to 800 then polish with 5X.  this would differently help the floor appearance

where the job located if you don’t want it I would be interested in it for my service company. If you are not going to take it

I hope someone may have some experence with this material, A city hall in central florida has about 1400 sq ft of this dark green bordered by a lighter "crema marfil" type light border, It was poorly installed with extensive lippage on every stone, its shows extensive wear, with some deep scratches where someone drug heavy fruniture. the city cannot give me a week to grind lippage, nor do i want to take metal discs for extensive lippage removal , nor do i want to spend nights for the next 5 weeks with 50 resins,and the city will not spring for full restoration.I normaly do not do maintance type work , mostly full restoration, any sugestions beyond a deep clean and severalcoats of a "floor shine hardner" like Stampede Gold buffed then regular maintance. This man made green stone scares me to death, any help appreciated.
