How to Sand Ceramic Plates?

Published in Ceramic Polishing 2 mins read

To sand ceramic plates, you'll need to wet the plate and sandpaper and then proceed with sanding. Here's how to do it:

Steps for Sanding Ceramic Plates:

  1. Prepare the Sandpaper: Soak your sandpaper in water for a few minutes. This helps to prevent the sandpaper from clogging with ceramic dust and also helps with the sanding process.
  2. Wet the Plate: Thoroughly wet the ceramic plate you intend to sand. This acts as a lubricant during the sanding process and reduces the risk of overheating the ceramic.
  3. Sanding: Begin sanding the ceramic plate using a consistent motion. You can sand in all directions, ensuring you cover the entire surface evenly.
    • Sound Check: Pay close attention to the sound. You should hear a change in the tone of the grit against the plate as you sand. This indicates that the sanding is effective.
  4. Grit Selection: Depending on the roughness of the ceramic, you'll need to select appropriate sandpaper grits.
    • Rough Bottoms: If the bottoms of the plates are particularly rough, start with a coarser grit like 250.
    • Refinement: Move to 400 grit for further smoothing, and then to 600 grit for a finer finish.
  5. Desired Finish: You can continue to use finer grits to achieve an "eggshell" finish, as referenced in the text.

Sandpaper Grit Guide:

Grit Use
250 For very rough surfaces
400 For initial smoothing
600 For a finer, smoother finish

By following these steps, you can effectively sand the bottoms of your ceramic plates to achieve a smooth and finished surface.
