Grind clinker - is that possible?

Even the very durable clinker surfaces can be exposed to abrasion and weathering over time. Whether it is possible to grind clinker, what consequences that has, and in which cases other methods work better, read in this post.

Sanding clinker

Although clinkers are bricks, the high firing temperatures (up to 1,200° C) and the long burning time have changed their surface.

When burning clinker, the temperature is always chosen so that the surface "sintered": This means that the temperature just below the melting point causes the position of the particles in the surface to shift and "pull together". The surface of the clinker then becomes a tough glassy layer where the pores are fused together. This layer is

  • very hard
  • almost completely impermeable to water
  • extremely resistant to all influences (clinker can be 100 years or even older)

Grind clinker - is that possible?: surface

If one were to grind clinker or even grind it, this surface layer would be destroyed. The stone would then be open-pored on its surface, which would result in more water being absorbed and the overall surface being more sensitive. Sanding is - as well as sandblasting not a particularly good idea.


tiled floors

In old houses are often still clinker floors. By use (often over 150 years or more), the soil has leaked, rubbed off and no longer visually beautiful.

In such a case, it may be worthwhile to turn the stones over easily. This creates a completely new soil with an éntakter, even surface of the old stones. In many cases, this works fine, even if the stones were grouted.

brick facade

If a clinker facade - if a renovation of the clinker urgently seems necessary - can be worked as well. Using the old stones, you can simply re-wall the facing brick of clinker. There are then no more material costs, since the clinker already exist. Of course, you can also turn the untrimmed stone sides outwards.

Tips & Tricks

Often, the "patina" of old clinker floors and the visible wear are the special attractions. If in doubt, you could then turn only single, more worn stones.
