How to Make a Mold (CHEAP)

Can you create a good mold of your sculptures at an affordable price? Yes, yes you can! In this lesson Andrew covers the materials needed to make a quality mold and the step by step process for making it. You’ll see how to apply the silicone to your sculpture and then the process of pulling the sculpt from the mold, and filling it with resin. If you enjoy this lesson and want the more in-depth one check out the premium course (link above).

I have used this silicone but with water and dish soap. You put the silicone in the water/ dishsoap mix and ball it up and then apply it and it dries within 10 mins. Works pretty good Ann's you don't have to wait so long. This seemed to work well tho

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.

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!

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.

I have seen many mould making videos, but your one is perfect to the point and easy to understand the process with its pro's and cons. Thanks for sharing 🙏🏻👍🏻

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

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

[KB_Grimweaver]

Very nice! Thank you for sharing this! Beautiful sculpting work too!
And thank you for bringing up ventilation. I don't think enough of the crafty Youtubers remember to mention this.

This is the best mold making tutorial on YouTube! You probably saved me so much money and stress..

[xpump]

a water pick is a good tool for demolding stubborn stuck areas

[jakelevinson]

What an amazing video I’ve been wanting to do molding for like genuinely like 5-10 years but it’s always been financially and feasible for me to kinda play around with

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

[karlalehnhoff]

This is the most professional tutorial! Truly for artists!! Thank you🙌

I remember doing this in college but using slightly different materials. Murphies oil soap being one. This looks far more complex.
My 3D Art class was in a barn and the guy who taught it was an old hippie who smoked cigarettes during class! Ahh the 1990’s.

[kiyannareynard-euph]

For your first layer, I'd recommend a technique from oil painting "fat over thin", so adding a solvent to reduce the viscosity of the silicone. This allows for a thinner initial layer. It will also dry faster due to the solvent content, that will evaporative quickly. And as long as subsequent layers have less solvent added, your risk of the inner layers drying lower will be greatly diminished

Professor, muito obrigada por partilhar seus estudos
Estava indo fazer minha pesquisa sobre silicone barato, pois impossível comprar o silicone e resina por estarem muito caros.
Você tirou todas as minhas dúvidas e vou fazer um molde desses para teste.
Muito obrigada mesmo por compartilhar

Super professional editing and work ! Thanks :)

Wow dude. Great video! Popped up in my feed while I'm sitting here waiting for $200 worth of Mold Max to cure on a head bust in a pressure pot. I made a mold with silicone calk in college. I thinned it with ...something? It might have been acetone ( it was 20 years ago ). Something dilutes silicone and makes it more like lumpy syrup, but I also remember that it weakened the silicone. It was just a one-off though... I'm gonna start fishing through your videos - this was great!

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. 🍻

Thank you, this was very helpful.👍🏻👍🏻👍🏻👍🏻
