if you did it would erase the small details because the resin would fill in those little details so you couldn't get latex in there.

Lol

You can get some flow increaser to help thin it out if you meed

Hi Samantha. The smell comes from both the ammonia used to maintain a liquid state and the sulfur needed for the foam to cure. For a while I used to add some vanilla essence to my foam to mitigate the smell… but the price rise made that cost prohibitive for me. If you can afford it it works well

ultracal 30 is pretty decent for long lasting molds. Ive been using it for many years. The molds last longer than pottery plaster or plaster of paris by almost 100 or more pulls. I didn't really like hydrocal because after a few pulls it gets more and more porous than before. Using heat above 100 F to 200 F will cause ultracal to crack or explode depending on how high the temp is because of its low shrink value. Sucks to have to vacuum your oven.

Yes, you are correct. Hydrocal is superior for its capillary action in regards to leeching out the ammonia and leaving a nice even skin on the mold. It is not, however, superior in terms of strength and library life. UC30 lasts a whole lot longer, you just need to leave it to dwell for longer and you will still get the same effect. When I worked at Universal we used to mix 2:1 UC to HC to try and wlk the line between both worlds. It worked pretty well. This mold needs to last for many many pulls, so I decided on UC30. I am not "reinventing the wheel". Many people use Ultracal 30 for mask molds. In fact, Rick Baker recently had Rob Freitas mold one of his mask molds and he used Ultyracal 30. Be careful throwing around words like "ALL" and "ALWAYS".

@@toxicimagestudios9547 what do I know, I've only been a special effects makeup artist for 40 years. I have hydrocal molds that are 30 years old . Now I use number one pottery plaster for all latex items .

I am not at all sure I understand what you’re asking, mate

I am not sure I understand what you’re referring to, mate.

@@toxicimagestudios9547 you talk about using an air gun to get the bubbles out of the UltraCal in the video. Could I use a heat gun instead or would that be too hot for the UltraCal?

I don’t think you would get the benefit with a heat gun. The air pressure is usually too l,ow and you risk more causing issues to your sculpt, especially if it is an oil based clay. Heat gun is the wrong tool. You’re better off just blowing on it

Believe you can use dust off though @@qt_sir

maybe a hair dryer on low heat. The heat could crack the mold.

Same Product, just an updated can design

I never have, but I am also sure I have killed some of the few active brain cells I had left with the ammonia fumes. I dont know anyone who wears a respirator to run foam, but if you feel more comfortable doing it then do what makes you feel better

It depends on how thick you want the mold walls, really and what you'll be doing with it. It also depends on the size of the sculpture. Too hard to answer without those specifics.

@@toxicimagestudios9547 it’s about 2.5x2 feet and want at least an inch thick

@@benwatford3068 Hmm, I think 25lbs may not be enough for you.

thank you

if you are referring to a hand turned egg mixer then no, that would not work. You wont get enough speed to get the rise you want and you wont be able to maintain an even speed whilst refining to avoid bubbles. You should use an electric mixer for sure.

depends on which speed of Ultracal you are using. If it is Ultracal30 then it should take 30 minutes if mixed according to manufacturers specifications. A good rule of thumb, though , is to go by the temperature of the material. If mixed effectively, it should heat up considerably as it sets. Once cooled you should be able to do whatever you need to it. If running foam latex, however, you will most likely need to bake out the mold to remove the unwanted moisture or you can get delamination.

you dont want to use gas as it gets too hot. Also, never use your kitchen oven as it makes everything smell like sulphur that you will bake in it

@@toxicimagestudios9547 got it. Thanks for replying back!

@@T-Rus no worries, mate

@@toxicimagestudios9547 what oven would be better? Electric?

@@T-Rus i always just build my own low temp cpnvection oveb

Thanks mate. I appreciate your kind words :)

could be. if its stained from the clay then some water with a dish brush would work better i think

@@toxicimagestudios9547 yeah i did it and i gonna pour another one to see if the stain is gone! Thanks for the respond!

My family moved to LA a few years back but ended up coming back. We now live in Las Vegas. It is decent there

The reason I l Ike WED is because it is very soft. If you use a hard clay then it can jack up your sculpt (if you are molding a sculpt). If you are molding something hard then you could absolutely use plastalina but it will be a pain to work with and finish down. You don’t need any detail and water clay is easy to clean out of the jacket. You can throw it fast also. If all you have is plastalina then you could in theory use it., but I think it would be better to get some water clay.

Due to the fact that I can’t hear it, it must be my badger million air compressor. If you watch the video on airbrushes and compressors I did it is the larger square blue one

Yes. Absolutely

@@toxicimagestudios9547 awesome thanks I'm literally about to mold the first half!

It was WED clay
