Silicone Molds for Concrete Casting

Casting concrete in flexible rubber molds allows for reproducing any shape and texture in concrete. Silpak polyurethane and silicone molding rubbers are the best options for making molds for casting decorative concrete objects. Concrete casting molds can be made by pouring or brushing the molding rubbers on a properly prepared master.

The current Silpak website represents a portion of the broader selection of concrete mold casting materials and products available for sale. If you are looking for a product that you previously purchased or a product that you require, please contact us.
