How to Mold & Cast Architectural Moldings

This Instructable video shows the process of making a silicone mold from an existing ceiling medallion and casting replicas using urethane casting resin.  Great for restoration work and one-of-a-kind pieces no longer available.

    Multiple times. With a piece like this I would say 50-100 maybe. You can also extend the life of the mold by using mold release spray prior to casting.

    Thanks! I normally use alginate, but you only get one shot with that and it would be nice to be able to do multiple casting.
