Save water and reduce erosion

Step 9: Casting

Be sure the mold is clean and free of debris. For the cast I used an aerosol mold release - Ease Release 200. Be sure to hold the can the correct distance away as shown in the picture. Spray it in a well ventilated area. I sprayed the mold fives times to be sure I got all the areas covered.

Mix the casting material (Smooth Cast 327) the same way as the silicone, from the outside in. I added glass spheres to the Smooth Cast 327 to give to strength. I did three pours as the casting material gives off a lot of heat and I did not want to damage my mold or start a fire.

Follow the manufacturer's instructions for times between pours and final curing.
