Do you want to cast your own concrete statue?
Have you made a beautiful model but don't know what to use to make a flexible strong shape?
You can use many types of silicone for concrete and cement. Silicones are flexible and can withstand concrete well.
The high elongation and enormous detail transfer of silicone makes it possible to effortlessly demould even fragile, highly detailed works.
Of course, it is also always important to determine which type of mold will work best.
More information about this can be found here. Are you stuck? Then we are happy to help!
Do you want a flexible mold that also has very little wear and tear? Then you can also choose a flexible PU with low shore.
Silicone moldmaking compounds have been used for decades in architecture to make high-quality imitation marble, stone and wood features from concrete, gypsum and casting resins. Molds made from ELASTOSIL® M silicone rubber faithfully reproduce complex shapes and the finest surface details. Here you will find a leaflet from our manufacturer Wacker about the most suitable silicones.
