How to Make a Mold (CHEAP)

try adding corn starch to thicken up the silicone and speed up drying time after the first brush on layer

You can also mix the silicone right into the dishsoap water to make a gum you can handle. You can press more simple items to make one part moulds.

Mix with naphtha to make it very brushable. Toxic and flammable, yes. Stiltbeast Studios has a few great instructional videos for this technique.

I would recommend scooping out a channel into your clay all around the edge with a sculpting tool. As you lay down your first silicone layers, it will fill in the channel and - when you remove the back later of clay - you will already have a half tube key. 🍻

MOULD making.. not MOLD. Yuk. 🤢

👍♥️

I came here for the $20 penicillin! 😂

So you are just using regular silicone caulk? If there is a specific kind please correct me. It looks like a lot of work, but I would like to do a mask like this. The extra work far out weighs the cost of smooth on stuff. This is really brilliant man. Thanks for sharing this. Again, please let me know specifically what caulk you recommend for a mask. I am subbing now. Just amazing! This may mean that I am no longer bound to latex. Not that I hate that, but it does have it's limits, and I think I have outgrown it for the most part. thanks again!

I will tell you a trick that will make this process much easier for the first layer. Naphtha is the key! Squeeze a bunch of silicone into a mixing bowl and add some naphtha and it will thin it down to be brushable and get into all the details and will dry normally and then do the next layers as shown!

Another trick for building layers of silicone is that you can actually add plaster of paris to you’re silicone as much as 50%

This makes a little silicone go a long way and you can make almost a clay like putty you can shape to build up layers or create keys.

Never add plaster for your first detail layer bit only for build up layers! Keep in mind it will make the silicone a bit less flexible and more likely to tear so it’s not as good for molds that need to flex a lot.

That brush is really working as a brus, not at all like a stick.

"20$"
Then proceeds to list 70$ in supplies

I feel like there was an adverse effect from the Vaseline that I put on my sculpture and the first layer of silicone. Everything but the first layer dried and the entire mold ended up failing.

If you add corn flour to your silicone it I’ll dry in 2 hours

Wow ... this guy is doing it the hard way! Mix silicone one with cornstarch or acrylic paint to have added water and have it cure fast. Simple durable molds. If you want to take it to the next level and capture detail. Brush on a couple of coats of platinum silicone with a few drops of thicker added. Then do a couple of coats of tin silicone one and cornstarch. Great molds but not quite as flexible as a pure platinum silicone mold.

What clay/material would you recommend for initial wall which you put the silicone against?

Using construction grade silicone caulking is the stupidest thing I've ever heard of, don't do it, you will regret it.

Love making making my own molds out of silicone... I make it with cornstarch. I'm glad I found this channel. 🇨🇦

I mean, I've been struggling with this stuff for quite some time.

Your idea is genius!

This content is amazing!

WOW, great tutorial. Many thanks!

You can make the silicone cure faster (within 2 hours) if you use some dish soap and water. Using Dawn dish soap, add a considerable amount to a gallon bucket of water. With the silicone and caulk gun, squeeze some out into your hand underneath the surface of the water. The silicone will not stick to your hand if it is wet. With a small handful of silicone start massaging and pulling apart the silicone in the water. Pull it like taffy and you will feel it start to stiffen in your hands after 30-45 seconds. Place the lump of silicone over the figure and spread it out evenly. Repeat these steps and blend together the sections of silicone you add together until it is fully covered. This method will cause it to cure within a few hours. Note: the silicone will release an ammonia smell while curing so do it in a well ventilated area. Some methods of increasing the curing time can be dangerous (using solvents and other additives) but the dish soap is perfectly safe even for children. Hope this helps!

Can you cast cement into this mold?

My molds usually cost less than 5$

Super educational….thank you ❤

This is crazy. Just buy the proper stuff. The fumes of hardware silicone is very bad.

exactly what we do in africa

What's the clay wall made out of? It's best to use a clay that's relatively softer so you don't damage the surface of the sculpture as you're forming the wall around it. If you use water-based clay, you can use water and soft brush to easily clean off clay residue.

Those cheap brushes are not ideal for what you’re doing, is it? I would think a small stainless sculpting spatula would be so much more efficient. The cheap brush looks terribly awkward to use, but especially it is very tough to smear the silicone smoothly. You even do better with a continuously wetted finger/thumb. Obviously use what you have, but just a thought. Thanks for this video. Very nice.

Very good explanation! Thank you!

Thank you very much doctor proko❤❤😊

thank you so so so much ♥♥♥

U can mix the Plaster and resin as well

You have a Ukrainian name.

Works fairly quicker and smoother if you mix the silicone with acetone or nail polish thinners its pourable as well

Well done and much appreciated instructions! Thank you!

Excellent! Very helpful. Thank you!

Okay, are there other casting options that may not stick as much as resin? Polystone? See, I think this would be perfect for me. I want to begin molding individual pieces of 3D printed statue designs. After all pieces are molded I want to try and install magnets and assemble them as something of higher quality.

Tutorial well done. Good details and suggestions for success. As for making my own sculpture, I'm not creative enough to make something nice so I may need to buy an object already made.

Your video is excellent, as are all your videos. It's a bit daunting how many steps there are to go through. But I like the idea of using cheap silicone😊.

Trying to make custom grips for my Rex Zero this looks like it'll help thanks

Super professional editing and work ! Thanks :)

Great video mate
