Moulding

Moulding - 9m Mandela Sculpture - Union Buildings - Pretoria - 2013

In order to get rid of the sandstone texture of the polyurethane foam, we re-worked the complete surface with plaster-of-paris (gypsum). This created a sculpted feel (to get away from the machined surface of th CNC) and also aligned all the joins between the blocks.

SCS simultaneously started with making the silicone rubber mould in a fibre-glass jacket whilst we were busy with other sections. The mould was mostly constructed in one piece only to be cut later with a diamond cutting blade into the desired workable mould pieces. This was done with the size of a wax panel in mind considering each piece’s weight and dimensions. Each piece was also ID coded, photographed in it’s place for future assembly.
