The clinker bricks are ideal for interior design, as well as for outdoor areas such as facades,

House base, wall embellishments open fireplaces, barbecues etc.


This is how it's done:


For indoor use:

  1. stucco (construction business / plaster shop) mix with water (thick).
  2. Spray the molds thinly with a release agent and fill with stucco. (Recommended: the addition of polypropylene fiber  to forced voltages absorb and thus prevent shrinkage cracks. (150 g / 4,00 € - sufficient for about 200 L plaster)
  3. Carefully shape after approx. 1 hour
  4. Let the stones dry .



With plaster adhesive, Dirspensionskleber or silicone.

Concrete clinker with construction adhesive.

For outdoor:

A release agent is always required. You can spec. Use release agent VARIO (available from us), with which you spray the molds thinly .

Then the filling material (eg ready-mix concrete from the hardware store) is filled.

When filling the molds you have to avoid air bubbles

For example, place the shapes on a board and repeatedly during filling

hit the board with a hammer or a vibrating table

remove the air.

If you want to make the concrete yourself pay attention to the correct mixing ratio (1 part cement and 3 parts not too fine sand). The mixture should not be too thin.

The drying time until removal from the mold should be at least 24 hours. Only after approx. 3 weeks is the concrete block to be processed without danger of breakage (with diamond disc etc.)


For a considerable improvement of the processing, the compaction willingness

and the hardened concrete properties we recommend our additive(Category concrete admixtures ).
