@saied49 Rebound 25 can withstand up to 450F. You may need to cut air vents, this would be dependent on the configuration of your original. You may want to investigate a pour-on material such as our Smooth-Sil series of pourable silicones for your particular application.
Smooth Cast resin, being urethane, has fairly good impact resistance. Our Smooth Cast 65D is designed with a slightly higher impact resistance than, for example, Smooth Cast 300 or 325
@BitsyBundlesReborns You would need to apply a release such as Ease Release 200 to the mold or the silicone you pour in would bond.
Awesome tutorial! Would this work for pouring silicone rather than resin?
A real man listens to two songs at once...and not turn the volume down.
Between all tutorials I see on my life... to draw or even to better at something... smooth-on has the best ones and by far
Thank you!
Very helpful thank you for sharing!
@maikeru01 Hello! You could use a pourable silicone such as our Dragon Skin series, and allow that to 'flow' over the surface of the piece before following up with brushed-on rubber.
You might approach an object like that by making a 2-piece mold or by propping the item up using something like wooden dowels.
Awesomeeeee- I'm going to attempt this again
Very nice video, i enjoyed it a lot! Quick question, what is the estimate cost for reproducing a 3.5-inch head sculpture?
I'm trying to make a sturdy version of a cane handle I have The original is made out of a hollow plastic material as it was a cheap costume prop. Would the resin be a good idea to cast it in? Or should I look into metal casting instead? Thank You!
if i wask to make a clay wolfs head could i use this same process to turn it into a soft foam version? i want to then hollow the foam out and turn it into the base for a quadsuit mask
this is just awesome
i think i need a product like this. the problem is, the object i want to mold is a sculpture made from non-hardening clay so i cant stipple and brush on the silicone so hard as she did in this video. any suggestions? is there a less viscous material i could use that would capture more detail with less force?
what should i use if i want to do this with a object that is curved sort of where it is a odd shape that i wouldn't have any flat surfaces to pour it into
So, you're saying it would be suitable for something like that? I've never cast anything before, so I'm just trying to figure out which materials are easiest and best to use. From what I can see in the video, it certainly looks sturdy enough for what I'm trying to accomplish. What is your professional opinion? Should I try this and see how it goes?
What you're hearing is a casting of the music inside its mold. That's how you make a perfect copy of a song.
Needs a "silicone sister with her manage mister" ....Probably? Maybe? Or maybe I am just blinded by all the light? As in th-cam.com/video/2GCr1eTbxbw/w-d-xo.html
How would one do this with a smaller object that doesn't have a flat base?
Thank you
can you use Brush-On Silicone Mold to make lead soldiers? would i need to cut air vents?
About how many times could you reuse that mold?
Magic is real!!!!
I tried to do this with standard runny silicone... a huge mess and never turned out alright. I can't seem to get any of this stuff in Denmark :(
This is amazing... I didn't understand the point of half of it until the end lol
Is this something you can do at home?
@brittany7734x92 Yes, as long as you have room sized ventilation.
Здорово!
Very helpful! Would be great to have names and links to exact products used in your videos.
This is a great idea! We will forward it to our video team.
You can contact FormFX in the Netherlands to receive materials.
What kind of clay do you use?
@MrMason917061 I would look over some of our other video tutorials or else visit our website for contact information for toll-free tech support and mold making advice.
@Ninjaculation what do you mean "usually?" :-/
Really need to know the name of the Background song when it first comes on sounds crazy I want to sample that
I wonder if I could do a cast of a clay sculpture?Greenware or fired clay perhaps?Thanks!
Hi there! This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!
Thanks for this. I have a question: how can you make it hollow to where you can shave off costs in the amount of silicone you use to pour into the mold while also reducing the weight of the figurine? Caveat: this may apply more to bigger, heavier projects/figures as opposed to smaller ones, none the less, I'd like to learn about the concept of creating multiple cast/hollowed molds that can be glued together or sealed from the bottom. TY.
+Like Kane sure, you can pour a resin like our Smooth-Cast 65D which slowly get thicker, then rotate the mold to coat the inside. Some call this "slush casting"
Smooth-On thanks for your reply, then I take it that the thickness or consistency of the resin has to be a certain number or measurement. How is your line of 65D resin different or ideal for slush casting? Also, how would I enclose it? For instance, on the bottom or the base of the figure, would I have to make a separate cast of the base and attach it to it? TY.
You would need to create a shim, or fill the hole with modeling clay, then cut the material from the finished casting once it is cured.
What is the material of the support shell?
too good
Can you do a video on a blanket mold which is the opposite of this type of method? The mother mold is done around a blanket of clay then you pour silicone into the mother mold to get a glove mold??
Hi Jennifer, perhaps this video will be helpful - th-cam.com/video/-3IBuyfFGw0/w-d-xo.html
What kind of modeling clay is that? It looks ideal for my needs - SOFT like pottery (water based) clay, without the worries of having to keep it wet.
Hello! I would suggest using a non-sulfur based clay! www.smooth-on.com/support/faq/178/
Can I cast silicone rubber (dragon skin) into this type of mold if I use Ease Release 200?
apm2103 Yes - I would spray a liberal coat of Ease Release 200, and then brush it around the inside to achieve good coverage. After, you brush the spray release around the inside of the mold i would then spray another liberal coat.
Good
Would this method work on latex rubber for cement casting?
The method is slightly different. This manual may be helpful store-fua89mr4.mybigcommerce.com/mold-making-manual/
good
looks like i need to invest in popcorn buckets.
I wonder how long the mold lasts.. I have a 3 inch piece i wanna cast in clear, but I want a bunch of them..
It depends on the speed of the resin, type of resin and the detail on the casting.
I just watched this video before using the product, then I noticed the label on the containers each say 1 part A and 3 parts B. Has the formula changed since this video was produced, or was there a strategy behind using a different ratio in the video?
There is a new version of Plasti-Paste called Plasti-Paste II which has a 1A:2B ratio.
I made a sculpture of a car out of a wax based not hardening clay. and i'll like to reproduce it in resin so i can sand and paint it. my thinking is i could brush on a silicone rubber mold, maybe reinforce with fiberglass but then when it comes to the resin, is there a resin i could brush into the mold ? it's a car body, so i wouldn't want to pure in resin and make a solid car. it should be hollow so i can eventually make an interior. could you suggest some advice?
+maikeru01 Our Smooth-Cast 65D is a popular resin for making thin walled, brush- in castings.www.smooth-on.com/Urethane-Plastic-a/c5_1120_1208/index.html
Smooth-On
How thick can smooth cast 300 be cast ? If I have say a life size bust would it cast all the way through ?
That would be a very large solid casting. I would recommend adding some Ure-Fil 7 to the 300 to reduce heat distortion issues.
I want to make a mold from an air freshener dispenser (the kind that sprays air freshener) can you suggest a product
+Work for yourself You may want to look at our Mold Star series of pourable silicones, then cast one of our TASK high performance plastics.
Is it okay to not add keys to a glove mold this size? Since it’s small?
I thought I should always add keys for the support mold.
In this case, the mold is small enough, and the rubber is firm enough that keys are not necessary.
I have a skull 1.5 human size. It has a bit of a neck too. Do you think I gallon would do the trick?
+DARK RIDE - Nightmare on Wheels this sounds about right. Thanks for watching!
Thanks, I will give it a go, I just didn't want to run out and have to order more. I know it is not recommended and once one layer (brush on) of the silicone is dry to the touch (about an hour) the next layer should be applied. I was fearing I would run out of material then having to wait a week to get more. Could it work if I did not, say, do the last 1 or 2 layers a week later?
my sister and I have a concrete statue that our great grandfather made.
It is living in her garden now. I would like a copy of it. it is aprox. 18 x18 x 24" tall. would this method work to make the mold? thanks, Paula
Can you send us a tech ticket? Our team can help you - www.smooth-on.com/support/ticket/add/agree/
Can I use Shell Shock instead, for mother mold?
You could, but it would require more layers be applied.
Smooth-On thanks, for helmet size object, how many layers are recommended?
We would recommend building up at least 3/8" (1 cm) thickness.
Smooth-On Ok thanks. Should I add thickener so that the Shell Shock can be troweled more easily?
Am i need a release agent before casting? I have cast 325
With a silicone mold, release is optional.
Thank you
What is the Material of the support shell ? it is like to play dough.
It is our Plasti-Paste urethane trowelable resin.
@VariablePenguin Hahahaha I noticed that. My mind started wigging out.
The background music to this video is doubled up I think. It sounds crazy.
Where is part one?

Why didn't she make any keys?
In this case, the jagged cut on the rubber and rough surface on the shell surface is enough to provide registration.
Didn't help. Destroyed chemicals worth of 130€ :/
The silicone sticks to the paste even with release spray.
Hi there, silicone shouldn't stick to anything except more silicone. Can you send us a tech ticket on our website?
I99
an no thanks not the technique i prefer.......silicone pour molds are somuch easier and faster
