Why do tile edges have to be sanded?

During the manufacture, processing, transport or cutting of tiles, irregularities in the external area are more common.

These are not nice to look at and can be faulted in most cases.

Chips, Bumps, Irregularities, Above Average Roughness or Sharp Tiles - Edges must be sanded.

Tiles cut edges visible?

Especially with tiles, an irregular profile is a huge disruptive factor. Therefore, these must be properly blinded. If there are visible edges, they must be sanded down.

Grind the edges of tiles with the angle grinder and diamond grinding pads

With this method you can "clean" your edges or polish them to a high gloss. You should therefore be aware of the goals you want to achieve.

The application is the same, but the tool to use is different.

You need the following tools and machines:

  • Diamond grinding pad of your choice (depending on the application)
  • Velcro recording plate. More flexible or more static.
  • Cordless or cordless angle grinder

Step-by-step instructions for grinding tile edges

Follow the steps below to get a good result.

  1. Prepare tools and tiles. Ideally on a trestle where you can easily let the tile overhang.

  2. Remove coarse dirt from the tile, especially semi-loose material in the edge area.

  3. Attach the mounting plate to the angle grinder and attach the desired diamond grinding pad to the center of the Velcro area.

  4. Set the number of revolutions correctly. With hard materials such as fine stoneware, you can work in the medium and high speed range. In the case of sensitive or soft tiles, it is advisable to approach them slowly. Best with a leftover piece of tile.

  5. Sand evenly from beginning to end of the tile edge to get an even result.

  6. Continue working with the appropriate grits until you have the desired finish/polish.

Round off tile edges

In order to be able to round off tile edges during the sanding process, it is necessary to work carefully. With a slight turning movement, you should be able to round off the tile edges accordingly.

It is best to start at the top of the tile edge and grind your curve to the desired degree (angle).
