                                                                                          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.
