Repeat the steps:
Make a mold wall with no undercuts.
Use mold release.
Mix plaster. (See instructions)
Use the paint brush until plaster starts to thicken then use a plaster spatula.
Clean up plaster with a knife or the spatula.
Just before the plaster sets hard, use a wet paint brush to tidy up.
Repeat the steps…
Work fast. It takes 10-15 minutes from plaster mixing to the point where it hardens. I try to mix one batch for each small piece, but when the piece is larger, it takes multiple batches.

Brush a very thin layer of mold release onto any surface where the plaster will touch. If there are brush strokes, they’ll show in your final piece. I use my hands to get rid of brush strokes and any excess mold release.
