Fiberglassing a plaster bandage head mold for The Custom Mannequin Project, 2014
Protective gear:
Overalls, rubber dishwashing gloves (the silver lined kind, not the flocked ones), respirator with organic & inorganic vapour filters fitted. Extraction fans for ventilation.
Method:
Molds have been prepped with 2 coats of shellac, 2 layers of mold release wax and 1 coat of PVA mold release.
- Qcell powder is mixed with polyester resin to a runny icing like consistency. This will keep for a few weeks
- The amount I think I need is poured into a separate container with 1% MEKP hardener mixed in.
- A thin layer is brushed into the mold and left to cure (either for a few hours or overnight depending on what else I'm up to, it doesn't really matter)
- A second thin layer is added
- 1 layer of chopped strand mat is put on top of the wet Qcell
- Polyester resin is mixed with 1% hardener and brushed into the mat
- 2 more layers of mat and resin is brushed in
- Once cured (overnight) the plaster mold is ripped off. The eye holes get cut out. Then the two pieces will be taped together and joined with resin and chopped strand mat (this is why my brush has a stick attached to it, to reach inside the head)
