set-up to dry plaster molds

[Diana Ferreira]

Hi there!

I have promised to show my plaster drying method. It is not perfect, but then again, the holes that is created allows damp air to escape :-)

 

When you dry your molds, you need to make sure that there is as little as possible of the plaster surface touching the ground. I use what ever is handy to lift them at an angle, thus ensuring that only the edge of the mold is resting on the ground.

 

If your used molds get 'mouldy' it is normally not mould, but rather the deflocculant that is forming the 'mould' that you see. I use Alcasperse. I normally just wipe it off the surface of the mold. As your mold absorbs/steals water from the slip, it also absorbs some deflocculant.

 

Wind will dry your mold. Wind in combination with heat will accelerate the process. So, I use a little fan heater. Within a couple of hours your mold (depending on size) will be bone dry.
