Squishy Breast Stress Relief Toy

Step 2 Seal the plaster

I did mine a little backwards (built a frame around it and then coated it), but before you figure out a way to house your plaster model, you should seal it with shellac or lacquer. Apply a few quick, thin coats until it is completely covered. It's best to use something that is colored so that you can see whether or not you coated the whole thing.

Once the sealant is dry, spray the inside of the rig with Universal Mold Release agent. Gently spread the release agent around with a paintbrush and then let dry for thirty minutes.
