Ceramic Base Molding

I also have a question re: ceramic base molding. We got Daltile base molding, if anyone is familiar with it, it is shaped like upside-down V-cap/chair rail & for some reason it is glazed on the bottom which is about 1" wide.
This brings me to my question: is this base molding supposed to sit on top of the floor tile or should I install it like cove molding, leaving a space between the floor tile & the wall & then inserting the base mold into the gap? The base mold has acurve on the bottom which would be covered if the floor tile went next to it, rather than underneath it, so I think it is supposed to sit on top. Then should I caulk or grout the joint?
Anyone know?

I have a question re: ceramic base molding. We went with Daltile base molding, if anyone is familiar with it, it is shaped like upside-down V-cap/chair rail (see pic) & for some reason it is glazed on the bottom which is meant to sit atop the floor. This brings me to my question: is this base molding supposed to sit on top of the floor tile or should I install it like cove molding, leaving a space for it between the floor tile & the wall? The face of the base mold has a curve on the bottom which would seem to suggest the shape of the shoe on wood baseboard.
This nice curve would be completely covered if it were installed like cove base so I think it is supposed to sit on top of the floor. But then should I caulk or grout the curved edge-to-floor joint?
Anyone know?

Hi Deb,

I'm not familiar with that shape. Should be the same as a standard shoe base, though. They are made to sit either on top of the floor or to be embedded behind the floor tiles.

Yes, it is a pretty funky shape right? Well, I think I will place it atop the tile because of that curve. Now is that an expansion joint? I don't think it would need to be caulked or grouted..I'll have to see when we're done. I will definitely post pics.
Thanks for the tip John!
