Making a Silicone Rubber Mould

Making a Silicone Rubber Mould.

First Half of Mould

The first stage of making a silicone rubber mould of your sculpture is to build up clay to the halfway point.



Around the edge of your sculpture poke some shallow rounded holes to key the joins of your moulds.


Roll out some clay ¼" thick. Cut strips of this clay 1" wide, From these cut out dovetails and lay out around the sculpture keeping them ½" away. These dovetails will hold the rubber in place when making your resin composite reproductions.

Cut out Dovetails.
   Dovetails on, just outside of the dot keyways.

Then with brush on a thin layer of mixed silicone rubber liquid. Let dry between coats. Build up at least 3 layers or more. Add a thickened layer of silicone rubber at least ¼" thick. Let Dry.

The silicone is now ¼" thick all over the sculpture and is now ready for the next stage.
