Braid,
The production rate is going to depend upon your technician. How long will he last on the floor doing edges. At time goes on his productivity will drop. If this terrazzo has never been in a natural polish starting at a 220 is probably not going to work. You will need to start at 120 and if there is not a good grind on the edges form the install you may need to go to a 50 grit. If you don’t get a good cut on the floor when it comes time to polish you will see the difference in the finish by starting at a 220. If the main section of the floor has never been at a natural polish starting at a 220 is not going to give you the results you want. In most cases the terrazzo installer leave the terrazzo at a 80 grit stone or grinding brick depending upon when the terrazzo was installed. If this is an old terrazzo 10 to 15 years ago the 220 is too high to start with you will probably need to start with a 50 resin, 120 , 220, 400, 800 depending upon the color of the terrazzo if a dark color you will need to go to an 800.
Have you done a sample?? This is the best way to determine where you nee d to start and this would give you an opportunity to do several feet of edges to time how long it will take to hone those edges. Hand work is somewhat tricky, it ready depend upon how you technician approaches the job some techs last longer before they get wore out. Other take breaks to rest themselves from the consistent bending and kneeling on the floor.
If you have a lot of edge work to do you may want to try the rack a tac for your tech to use. This is available from StoneCare Central and is better than the roller knee pad you are probably now using.
When you’re not sure about a job, do a TEST tell your customer the test will allow you to determine the best possible price for them and it allow you to shoe the customer the results you are going to achieve.
Hope this helps

It is a portland based terrazzo. We ran into the hone mark problem with a project a little while ago. It was a marble floor that abbutted a polished marble wall. We used cerafil or some other form of wax with a dremel to work the edges. That seemed to work pretty well. I'm not sure that will work here.

Is it a resin based terrazzo or a portland based? If it's portland you'll have nasty hone marks along the edges to get rid of so just be careful because they'll really come through when you polish and a 200 grit wont come close to getting them out.

Hi. We are looking at a terrazzo floor and, because the floor was never finished (honed and polished), we will need to hone and polish the edges. We don't run into this much with marble because the edges are typically already polished. Was wondering what people's experience is with production rate for hand honing and polishing. We would go 200-400-800 and polish for the main floor, but perhaps that is not necessary for 1-2 inches of edge. Also, is it best to hone and polish the edges first or last?
Thanks,
B
