After the sculpt had been sanded it's ready to be used to make the mould. I used plasticine, silicone, gauze pad and some plaster to make the mould.
I think it was pretty hard to make the mould, it's been raining everyday and that made it hard for the silicone mould to fully dry.
making the silicone mould:
- use plasticine to make a block covering half of the sculpt.
- make sure to create a slot in the mould where you will use that slot to pour resin into the mould.
- create interlocking buttons using end of a pen.
- pour a layer of silicone onto the block and wait for it to dry. (90% dry is ok)
- place gauze pad on the silicone. This will help hold the silicone mould together.
- apply more silicone and wait for it to be 90% dry. repeat this step until the mould is thick and strong enough to hold it together.
- After the silicone mould is fully dried, put a mixture of plaster on top to create a plaster cast that help hold the silicone mould in place when doing resin casting.
- repeat the steps above to make the other side of the silicone mould.
To resin cast, I bought 1kg of normal resin ( I think it's called PC-600 ) they already put 10% of cobalt in the resin mixture. I also got the resin accelerator (10g) For this project I mix the resin with some calcium carbonate powder.
resin casting:
- mix resin with very little amount of resin accelerator, mix well, and pour the mixture into the mould.
- wait for the resin to cure. It will begin to heat up.
- once the resin is curing ( you will be able to remove it from the mould but it will still be a little bit soft. remove from the mould and cut off any excess that you don't want)
- wait for the resin to fully cure. It will get really hot that you don't want to touch it.
- put the resin figure into a bath of caustic soda and wait for a while.
- remove the resin from the soda bath and wash it with tab water, use a toothbrush to brush off any dirt and excess.
- let the resin figure dry out
- fill up any air holes with epoxy that might occur when you were casting the figure.
- sand if needed
Spray paint
to spray paint, make a small hole on the bottom of the figure and put a stick there so it's easier to hold the resin when spray painting it without having to touch the figure directly.
spray painted off white / skin colour first, then masked it out and spray painted white. Maksed out the white part and finish with black spray paint.
Making the package
I bought some 10x10x15cm card boxes and use photoshop to design the pattern for the box and printed them out on matte 230 grams card paper. I cut the pattern out and stuck it on the box using glue spray. I also put black sponge rubber sheets inside the box for better protection of the resin figure.
Stickers
I drew the design on my ipad and sent them off to be printed on waterproof sticker and cut them out.
