Step 5 Pour the rubber mold

Slowly pour the rubber into the lowest possible point inside the mold and let it fill from the bottom up. Continue until the rubber is at least 1 inch higher than the plaster mold. Once done, give the whole rig a few good taps against the ground to force any surface bubbles upwards.

Place the mold somewhere outside where it is dry and not windy (or in a well-ventilated area) and let it sit for about 24 hours.
