The shapes are unlimited often reusable.

This is how it's done:
 
A release agent that wets the mold is always required. For this purpose, spec. Trenmittel VARIO, with which the form is sprayed thin. Then leave to dry or rub with a cloth, so that no release agent is more visible. (The more often the molds are used, the easier the cast concrete piece will dissolve)
 
 
After introducing the release agent, the molds can be easily filled with concrete or concrete mortar. The filling material (which is very well suited, for example, the screed concrete from the DIY store + approx. 5% cement) must then be compressed to prevent air pockets. For this purpose, the shape is simply beaten several times on the ground or removed by means of a vibrating table, the air.
 
If you do not want to use a ready-to-use concrete mixture, you should take care when mixing the concrete to the correct ratio (1 part cement to 2.5 parts not too fine sand / gravel) and do not use too much water, as the mixture should not be too thin ,
 
The drying time until removal of the concrete pieces from the mold should be at least 24 hours and then they should continue to dry. The molds can immediately be filled with concrete as described, after 24-48 hours the concrete pieces can be removed again and ...
Only after about 3 weeks the concrete pieces are to be processed without risk of breakage (with, for example, diamond cutting disc).
The substrate must be suitable and compacted before installation.
