We have 1" stainless steel mosaic tiles for our kitchen backsplash. I've tried grouting on a sample and it leaves scratches. Is there a good technique for avoiding scratching the stainless? I am using unsanded grout, of course. Ive read suggestions to cover the tile surface with painters tape, but this is not practical for several thousand 1" tiles. I tried using a soft rubber grout float and mixing the grout to a more watery consistency so I don't have to press too hard to get it in the joints, and this seemed to help. Anyone have any additional tips? Thanks!
I have never seen stainless steel tiles actually used before, but always imagine them looking awesome. I wouldn't grout the tiles in the conventional way. It would be too risky. The only way I can think to do it is the hard way. You can get the grout that comes in a caulk tube and go line by line filling it in. It's not as bad as it sounds and shouldn't take too long to do. If you want to mix the grout yourself you can use a grout bag, which is like a frosting bag, but for grout. I'd be curious to learn of any other ways to do this as well. -Gregg
