Shower tile replacement

The contractor just left after installing 16 x 16 Noce tile in the kitchen/dining room/laundry room. They moved the fridge and stove before they left and while I heard them sanding on something I didn't pay any attention. The floor is still dusty looking and I had planned on mopping and sealing it Saturday but when I went in and looked, they had used sandpaper to try to sand out scratches left when they drug the appliances across the floor. I'm going to call him, I'm waiting for my husband to get home from work to get a second set of eyes on it and make sure I'm not imaging things. But I was wondering, before I go into full on panic mode, is there anyway to get scratches out of Noce stone?

Ugh....It seems I've gotten myself in a bit of a pickle. My plan is to retile my kitchen/laundry. I've already bought half the tile (at a bit over $500). There area is 465 sq ft. I had psyched myself up to do it myself (I've done tile projects before..but not quite this large). I started to remove the tile in the laundry room this evening and ran into quite the problem. For reference...I redid the bathroom on the second floor about a year ago (about 50 sq ft). The same ceramic as in the kitchen was installed there. I removed that tile with a manual scrapper. It came up just fine. No issues at all. The tile in the laundry room is NOT coming up easily. I believe the tile was set with an adhesive rather than thin-set (I think it was thin-set in the bathroom). The stack up appears to be: plywood, metal lath, about 1/2 inch of mortar of some sort and then the adhesive (I know this because in the process of removing some of the tile I managed to "dig" down to the lath). The tile will not budge with the scrapper. The scrapper doesn't seem to want to go up under the tile edge. It's difficult to get it off with hammer and chisel. So my question is: What are my options??? Would renting one of those powered scrappers make the job much easier...without ruining the underlayment? Or would that just be a waste of time/money? I'm thinking it might be best to hire someone. But..I'd rather not because I'm guessing that would be something on the order of $2000 ($5 per square). It defeats the reason I wanted to do it myself. I haven't checked the rest of the area (kitchen and hallways) but I don't think it would be any different in terms of difficulty. I do not want to chisel 465 sq ft of tile!!! :eek: I've gotten myself pregnant on this, I guess, so I have to take it to completion in some way. Thanks. Osprey
