Yes, sandpaper. You must remember to use very fine-grit sandpaper, and the porcelain must remain wet at all times. As long as the porcelain is wet, the sandpaper will “float” on the surface and will not scratch it.
Also to know is, can you sand tiles down?
Sand the tiles with a hand orbital sander and 220-grain sandpaper. Sandpaper with a 220-grit will remove the shine from the tile, but won’t leave permanent marks. It will also rough up the surface. Check to make sure the tiles appear scratched and feel rough after they have been sanded.
Considering this, can you use sandpaper on ceramic? Many types of files are made to sand down ceramic tile edges. Because they are already mounted on a handle, they give much better control than using a power sander. Files are perfect for sanding curved edges and can be found in a variety of grits or coarseness.
Then, what is the best way to sand ceramic tile?
Use an orbital sander and sandpaper with a fine grit. 220 grit is recommended to sand ceramic tiles. This will take the glaze off the tile but still leave the surface smooth. The sanding needs to be a slow and careful process.
