Model Making Materials

Rock mould boulders

Use this mould to make rocks for places where rocks might pop out of the terrain, such as embankments, ditches and hillsides.

• Rock mould size: 127mm x 177mm (5 x 7").
• The mould is flexible and reusable.
• Fill mould with with plaster.
• Plaster can be coloured using pigments (add to the water before mixing with the plaster). 
• Add detailed shading once the plaster is hard. 
• Disguise the edges with grass or plant material.
• Woodland Scenics C1232

Create granite rocks by pushing Keramistone modelling clay into the rock mould. It dries hard overnight and there is very little finishing required.
