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.

I believe you can use cornstarch or talc instead of plaster, which is cheaper. I haven’t tried using plaster, so I can’t say if it’s the same as using starch or talc.

Cornstarch is a better and safer choice by far. Plaster of Paris is somewhat toxic and should always be used with gloves and especially eye protection !...getting it in your eye is extremely dangerous.

Would you happen to know if the naphtha/silicone mix will keep in a sealed container and not solidify?

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

@@TheDarkArtist66Could you help, made the silicone using the soap method but it kept shrinking and wrapping within a few days. Any idea why and how to avoid it?

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 thin silicone with naphtha to make it brushable or even sprayable for the first detail layers. You can also add plaster to silicone to thicken it and make it dry faster.

Super educational….thank you ❤

Thank you very much doctor proko❤❤😊

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

Great video mate

Great video 👍

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!

@skateboardingjesus4006

Жыл бұрын

Isopropyl alcohol with the highest possible alcohol content, is the best for diluting silicone. The problem is that any thinners will evaporate from the cured silicone, making it shrink and in most cases warp. Molds made like this with very consistent wall thickness can have their evaporation gradually controlled and can be an excellent method for making reduced scale castings. It is very hard to learn to do properly and is not recommended.

@@skateboardingjesus4006 No kiddin. I wonder if there's commercial mold materials that offer such a consistent shrinkage, that they're sold as "scaling down" molds. I bet what you described is really hard - definitely over my head. I made a silicone calk mold so long ago - lol - it might have been the 2d thing I ever cast. It was a figure relief, and I think I first tried to cast it in polyester resin ( like, for fiberglass ). It wreaked the place up sooo bad. I was trying everything in college. I even tried to make castings in synthetic asphalt. Basically patch material for driveways...

Great video! I have a few questions: (1) How many tubes of silicone should we expect to use for a piece of this size? It is tough to tell from video just how much or how little we should use. (2) Would this work well with something like hydrocal? (3) how many castings do you think someone could get from a mold like this before there is noticeable degradation of the mold?

@AndrewJosephKeith

Жыл бұрын

1. I think I used about two tubes. 2. I use hydro stone (very similar to hydro cal) and it worked great. 3. The mold will wear out in areas but you can also use silicone to repair it. I'd say I usually get 10 or more casts before it starts to have noticeable wear or leak along the seam. But if you're using a material like cement to cast it wears faster.

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.

@AndrewJosephKeith

This is chavant nsp clay that is oil and wax based. It's a firmer clay which helps to not mess up the sculpture when mold making.

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!

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.

My molds usually cost less than 5$

This is probably a good practice material. I would have wasted a lot of money if i started learning epoxy molding with a decent quality (expensive) resin. Its not fun to throw away $30 of material because you're not good at mixing add-ins yet.

@AndrewJosephKeith

Yeah exactly. Learn the basics with this cheap stuff then move on to higher quality materials once you know what you're doing.

They put on for their what?

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.

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

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.
