Barry,

 

I would approach the floor the following way.

 

1.       First educate your customer that the floor was grouted improperly with sanded grout, and explain why non- sanded grout is to be used on natural stone.

2.        Then let the customer know that you will use every precaution to prevent the sanded grout from scratching the floor during you restoration process.

3.       Then when you start the job, do a chemical clean with StoneCare Central Neutral cleaner and a soft brush. The brush will break loose most of the sanded grout that could cause you problem during the restoration process.

4.       Then hone you floor as you normally would using you diamonds.  Pay attention during this process if you hear excessive honing stop vac up the slurry and check you diamond t make sure you haven’t picked up any sand.

5.       After you completed the honing for extra precaution if you want scrub the floor again to make sure there is NO loose sand on the floor.

6.       Then polish you floor as normal.

 

You make sure you customer understands you could have a few scratches in the floor due to the sanded grout.

 

If the floor has been down for a period of time you probably won’t have any problems with the sanded grout.
