Very versatile they produce moulds for a wide range of casting applications such as polyesters, epoxies, plaster and concrete casting.

Porous or damp formers should be sealed with G4 sealer. Available in various grades offering a choice of flexibility. The more flexible the rubber the less durable. Yellow is the hardest.
