Can you stain glazed tile.
Soak up some stain on the sponge and wipe it onto the tile.
Run the sander slowly over the surface to dull the glaze the point that it looks flat instead of shiny.
Wipe up the dust.

If you have a matte finish without glaze it may be to your advantage to seal the tile in order to stains.
Therefore sealing the tile itself would be overkill.
Applying masking tape along the edges of the area that you want to stain will also help you achieve clean and crisp lines.
Tile that has been treated or sealed will also have a hard time accepting a stain or paint.
For tile that has a slick surface it will need to be sanded before a tile stain or paint can be applied.
Staining ceramic tile can change the ambiance of a room.
