How To Cast a Concrete Fence Which Exhibits Detail Never Seen Before
Step 2: Mold Making
Three separate layers of Rebound® 25 mold rubber are mixed and applied. Silc-Pig® red pigment is added to the 2nd layer to ensure thorough coverage. Thi-Vex® thickening agent is added between the 2nd and 3rd layers as needed to fill in deep detail and undercuts.
After all layers are allowed to cure, a mother mold made of fiberglass and resin is applied using a chop gun. Steel tube segments are placed and encapsulated in the fiberglass at strategic points to provide level support and prevent the support shell from distorting.
