hi i would like to know how to make a 2 piece mold out of plaster for a buste that i have made with i wont to reproduce in a resine thankyou
HI. is the item you have made of plaster.and you want to make a mould of it.
If you're going to reproduce in resin, you don't want a plaster mold. You need either a polyurethane or silicone mold. I suggest (and always will) my suppliers for ideas. either smooth-on.com or polytek.com
hi thanks would silicon be ok to pour over my clay buste
You will definitely need to seal the model and then use a separator. They make both sealers and spray on or brush on separator for resins. Check out smooth-on.com and spend some time viewing their videos. They cover just about every way to use their products.
