I got a sample piece and I had my work cut out for me. I used a 400 grit resin to scratch the surface. I went 800, 1800, and 3500 5 inch flex resin pads. It looked like crap needless to say. I tried 1000, 2000, 3000 alpha pads. Looked better but still not quite as good. I then went and tried some marble polish no results. I tried light granite polish and it left very heavy swirls in the finish not very happy at this point. I started over using the 1000 alpha pads and that wasn't taking them out.   Frustrated I got my NSI rigid turbo pads started at 1000 rigid and that took out all the marks. I finished using 1000, 2000, 3000, and finally polished with mb 20. That worked great, so I redid the process and it worked.  They said there was a resin coat to protect from etching, but after finishing I put lemon juice and it still didn't etch. I'm assuming this more of a granite than a quartzite. Here are some pics after

Hi Baird,
The material is super hard-it is hard to cut using regular diamonds.
Our coppers work really well on that material but are just to soft for aggressive work like deeper scratches. Alpha turbos and or other turbos work pretty well on it-you have to be well skilled in working with wet to dry techniques. MB20 seems to finish it pretty good however. Its one of those surfaces that if you don't have the mileage or cant predict the results-you may want to practice on a spare piece first.
So many stones today being sold as quartzite that just arent-another problem-so I think testing the surface is very important before working on any thing labeled quartzite.

Stu, are you saying that true quartzite us unpolishablenor just very hard to polish?  How do they polish it in the factory?

Justin,
Make sure you test the sample piece to make sure its quartzite-try and scratch it with a piece of glass-if you can scratch it aint true quartzite-
Anyway the scratches from the backsplash guy may only be scuffs-they may come out with a polishing compound.
I can see the detail in the pics regarding the seem-if it isnt too bad-use our honeycombed copper pads from 800 thru 3000-go wet to dry with 1500/3000 then use MB-20 for final polish.
Hopefully the damage isnt deeper than that-the seam looks like it has blowouts from an inferior blade-be careful

If that is true Quartzite which it looks like -you will have issues polishing it.
Whats the name of it-? be very careful -test the spare piece.

Hi all
I have a call from an installer who has installed quartzite counters. They smoothed out a seam and didn't get it to match the original finish.  The backsplash installer didn't cover the counter while installing scratched the surface with buckets and tools in one section.   The installer says there's a resin coating on top as well. He has a sample piece I can work on, but I'm wondering how to approach this and what experience anyone has it fixing this. I've attached pics but it's hard to see the scratching
Thank you
Justin
