This model has overall dimensions of 5.5" x 2.75" with four casting chambers, each measuring 2.5" x 1.5".
A release agent must be used due to the rigidity of the molds. Ease Release 200 from Mann is highly recommended. Just spray the release agent into and on top of the chambers ensuring complete coverage and allow to dry before pouring your resin.
Apply a release agent to the rubber plugs to keep them free of any resin buildup caused by potential spillage.
A rubberized dead blow hammer will help the demold process greatly. Lightly rap the bottom and sides of the mold once your blanks have fully cured, then turn the mold over and lightly rap the mold ends against your work bench top to see your blanks release.
