GRUMO® is ideal for the construction of large sculptures made of concrete. This machinable base mortar can be used for laminating and modelling and for processing large sculptures with a plastering machine using the spraying technique. For smaller workpieces GRUMO® serves to create a strong base body before details are processed with MOMO® modelling mortar. GRUMO® and MOMO® are perfectly matched to each other for this purpose.

The base material is white and can be coloured by adding pigments. The material can be shaped for up to 2 hours and hardens after one day. By mixing with BUMS® universal mortar the set can be accelerated as desired.

GRUMO® results in a weather-resistant and frostproof concrete and, because of its excellent properties, is popular not only for artists but also for DIY enthusiasts who want to make garden figures for themselves.
