Give your plaster mold a good coating of clear acrylic spray paint, let it dry throughly. I like Krylon matte. Then a coating of bowling alley wax, bush it on, let it dry and rub it in with a cloth. Then give that a thin coat of PVA. The PVA will wash off with anything that you will use. Sure fire way to get the best casting you can.

NEW! MoldGel SILFREE. A revolutionary formula.
Made with all food-grade ingredients. It nourishes
the earth when discarded. 3-to-1 mix ratio yields
twice the volume as those 1-to-1 brands. Delayed
shrinkage for delayed casting - so creamy smooth, too.

plaster mold releas & cleaners:--
While we’re on the subject
I’m trying to find a way to caste polyester resin in the plaster body molds and not have an oily residue left over on or in the resin.
Sometimes it’s not cost effective to do a whole body caste using silicone but I’m having trouble finding a mold release that actually works or using oil base products and find oil residue seeping through the final finish.
I’ve tried spray silicone, it doesn’t work & we have to pry the pieces out.
We’ve tried petroleum jelly and cholesterol and the pieces detach easily but they don’t clean up. We’ve used mineral spirits, dish soap, degreasers, acetone, dishwasher detergents and still find oil residue seeping out of the resin weeks later.
Any ideas?
