The rock former is prepared with a release agent made from water and detergent. The included casting frame allows even moulding with NOCH PROFI Casting Compound. After hardening, the rock is carefully removed from the mould. With the help of the NOCH PROFI Casting Compound, the rocks are integrated into the modelling landscape and transitions are shaped. Now the rocks are coloured. Heavily diluted NOCH Nature Paints are applied with a sponge pad. The application of different colours is repeated until you achieve the desired result.
