DAP Plaster of Paris

Postby jschrempp » Mon Feb 16, 2015 2:55 pm

The box calls for one part water, two parts plaster of paris. When I did the first mold of my head the PoP seemed too thin so I added more powder. It took three days to completely dry. I thought that was due to the thickness of the part.

Today I made a second mold and mixed it 1:2 as called for. It was thin when I poured it in but it appears to be setting more quickly.

Re: DAP Plaster of Paris / hobby or craft version?

According to James A Mason (good name) at DAP

The Hobby and Craft formulation is formulated to release easier from molds when used for casting.
Application of a bond breaker material is still required when using the material for casting.
