How to make a Latex Mold

[MaddoxDare]

what is that in 1:03??? glue gum???

[tapplastics]

@MaddoxDare Go to any hobby store and ask for a glue gun. It is a common item for temporary bonding.

[Espie1979]

what a time consuming method. what is the advantage of latex over silicone rubber? Silicone rubber is much less fiddly than this method

[tapplastics]

@Espie1979 Cost! Latex molds use less volume of a less expensive material. A latex mold can be made for a very few dollars. But, you are right, it can be time consuming.

[PbSlytherin]

@laurafromsheffield are you absolutely positive because I need to make a too part mold but like how you make urethane mold from these tap vids

[PbSlytherin]

Can you do this in two part mould?

[tapplastics]

@PbSlytherin Yes, you can make two-part latex molds.

[stacky852002]

Do you need to use a release when pouring in the Urethane RTV molding rubber into the mother latex mold?

[tapplastics]

@stacky852002 Mold release is recommended when casting with urethane.

[Planetsp00n]

would the latex get damaged if i where to use clear casting resin in it?

[tapplastics]

@Planetsp00n No, Clear-Lite Casting Resin does not harm latex molds.

[maikeru01]

do you think this technique would work if the object i'm trying to cast is made of non-hardening clay? would the casting process melt or damage my clay sculpture? I'm trying to find a way to make my sculpture into a hard material, but it seems like almost anything i could use would probably just destroy the clay. thanks.

[tapplastics]

@maikeru01 It depends on how hard the clay is and its shape. You can certainly brush

on the latex without damaging the clay. But, after the mold is complete,

pulling it off the clay will likely re-shape the clay. If there are

undercuts, the clay shape will definitely change as the mold is pulled off

like a glove. But, once you have the mold, you can cast parts identical to

your original clay piece.

[xHacMan]

you can cover the brush in a thin coat of washing up liquid to stop the latex damaging the brush

[Kakorone]

Thx. I am using MOLD BUILDER - Liquid Latex Rubber to mold with easy cast casting epoxy

[Powerhungry5000]

umm, could I cast with latex? and if I cane, can I pigment it black?

[tapplastics]

@Powerhungry5000 Latex cannot be used for casting because it will not dry in thick quantities. If you wish to cast rubber parts, use Urethane RTV, or Silicone, both available at our website.

[laurafromsheffield]

@tapplastics Latex can be dried in thick quantaties I have to work with it every day as a special effects makeup artist, you have to be patient and leave it for a few days in open air. But i agree that Rubber or silicone would probably be better for large quantaties.

[adrian14643]

can you use this method with oil base made sculptures

[tapplastics]

@adrian14643 Avoid any petroleum based materials.  They will damage latex.

[dzine13]

Very helpful... thank you.

[MELDtoys]

YouTube is the greatest classroom in the history of the world! Of course, it helps to have a master teacher! Thanks again!

[ladyborat1]

would this technique work if i was making a mold of teeth?

[tapplastics]

@ladyborat1 Yes, as long as they are not in your mouth. 

[19Gui86]

very usefull thanks

[smokethatcheeba]

i purchased some latex moulds from ebay but they do not fiber glass on them does this matter?

[tapplastics]

@smokethatcheeba No, however fiberglass makes the mold more durable.

[kuliana28]

I've begun making a latex mold of a large flat sculpture, and the latex has begun shrinking and pulling away from some of the recessed area's. My plan was to add about 20 layers before applying the support shell, but I fear that adding more layers at this point will only distort it further. What should I do? How can I avoid this in the future?

[tapplastics]

@kuliana28 Shrinking and pulling is not uncommon in large flat molds. How large is your mold and what is the material it is made of and how much detail is on the original?

[skstepunk12727]

Hello In school I made a sculpture of a chimpmonk and i want to sort of clone it, i bought ur products but is it safe to put it on my painted chipmonk?

[tapplastics]

@skstepunk12727 non porous surface usually do not need a mold release, but we do recommend TAP Wax Mold Release, however you need to test the paint to see if it is effected by the mold making material

[Fuchsia5]

Is there a way to secure the mold support made of fiber glass to do not cut ourselves?

[wballe88]

My original impression has a very glossy surface - if I cast resin in the latex mold, would it reproduce the glossy surface?

[tapplastics]

Not as glossy as the original but it will be glossy.

[SuperAnimatorPro]

See, I wanted to make a puppet, much like the ones used on The Nightmare Before Christmas, I beleive they used latex, how can I make a mould of a clay model so that I can pour my liquid latex in let it dry and take out a completed puppet ready for painting?

[tapplastics]

The latex in the video is a brush-on material. It cannot be poured in a mold and then cure. It must dry in layers. If you can brush the inside of the mold, then you could duplicate the puppet. Chances are the puppets are made out of a different material than demonstrated in the video.

[oddsource]

A heat gun is faster in my opinion but then again I work more on ceramics than with latex

[MichelleTCM]

@oddsource It is really eay to burn the latex (turn it brown) with a heat gun.

[oddsource]

That is easier to make than a silicon mold from what I was taught in sculpture class in college.

[halfmumi]

6 stars...

[MrPacmanpacman]

very interesting! Is this the ordinary latex we use to paint on walls?

[tapplastics]

It is completely different from latex paint. There is very little latex in latex wall paint. Our latex is 74% latex, which is the highest concentration available. There are no fillers, clays, or pigments, which make up a major portion of the paint formula. If you apply paint until it is 1/8" thick, it would not feel anything like a durable rubber the way our Premium Latex behaves.

[patrickbateman00]

Can you re-melt the mold if a mistake is made, How would you do it?

[tapplastics]

No, once the mold dries, it is permanent.

[AbdelJaffar]

can u use this same method to mold a bigger piece like a muscle chest made of clay

[tapplastics]

Yes. There is no size limitation. You will just need a good mother mold for the latex.

[WinterHaven]

I like the plaster of paris thing.

[lllswamplll]

Lovely !!!!!!

[blackskulldecks12]

i very like the video

[zigax]

very good

[ulmboy556]

would it work to make a mold where you pour rather than brush on

[tapplastics]

You cannot pour on latex. However, silicone and urethane can be poured on. Look at the videos 'How to Make a Silicone Mold' and 'How to Make a Urethane Mold'

[305Erwin]

can u make mask's like this to

[tapplastics]

Our Latex Mold Builder is not designed to be applied to skin.

However, if you have a shape you want to apply the latex to, then you can make a mask that way.

[dannyproductions211]

could you make a brush on type latex mold?

[tapplastics]

Brush-on molds are the only type that can be made with latex.

[dannyproductions211]

could you make a two part latex mold?

[tapplastics]

Yes, a two-part latex mold can be made, though it is quite time consuming.

[dannyproductions211]

cool, thanks!!

[chochanga]

Great video! Thanx! Question: Why not use only latex? (I mean, without the fiber glass). Like in the silicone mold video. You know... pour a lot of latex in the container where the piece is. Bye !!

[tapplastics]

Unlike silicone, latex 'dries' by air contact. A thick layer of latex will dry on the surface, but then the inside will never dry. That is why it must be applied in thin layers, so that each layer can dry before the next one. Silicone, on the other hand, 'cures' by chemical reaction, without the need for air contact. So a big block of it will harden just fine.

[chochanga]

Great video ! Thanks ! Question: Why not use only latex? (I mean, without the fiber glass). Like in the silicone mold video. You know... pour a lot of latex in the container where the piece is. bye !!

[yelloloco]

can you pls help me? i want to make molds for small screws and parts with holes. how do i make molds for those parts?i'm a hobby man and i love to learn

[tapplastics]

Without knowing the exact shape of the part, it is hard to give an answer. You might find the information you need in the videos "How to Make a Urethane Mold" and "How to Make a Two-Part Mold" at our website.

[viena3]

Fantastic cognitive video! Thanks a lot!

[HIJOLESMANO]

Hello! where can i find your products in México? i live in Guadalajara, Jalisco. Thanks!

[tapplastics]

No, our stores are only in the US.

[maticoff]

Are you able to send shipments to the UK?

[tapplastics]

Yes.

[maticoff]

Thanks for letting me know.

[Emmarockz01]

What's the second method for a non-flat surface?

[Gameking53]

This was very helpful thanks so much :)

[p4cm4n182]

thanks

tap tap plasticss

[Jadoremode]

love the jingle! I little retro.

[anonymusbob101]

I think I'll visit your website and take a look at this latex.

[anonymusbob101]

How do you make sure that there are no thick areas of latex, or how to apply the second coat after the first one, and how do you make the plaster release? Sorry for my many questions.

[tapplastics]

Careful use of the brush is how to control the latex thickness. Since the latex is white, thick areas are easy to spot because they are opaque. The second coat is applied just like the first, after the first has dried. No mold release is required for plaster. Just make sure there are no undercuts or the plaster will lock on to the mold.

[BeBunny07]

Ok so if i want 2 make a mask out of latex how can i do it?

can u plssssss

tell me how ?

plsss messege me or reply!

[tapplastics]

Latex Mold Builder is not designed for applying to skin.

[Give1Get4]

Thanks for the information, it was very helpful as my husband has started his own business making concrete critters.

[AaronGreen]

wow, that is super helpful

[whateverme16]

nice... veary nice...

[omlet245]

is latex bad if it comes in contact with your skin?

[tapplastics]

Latex is not harmful. It can be washed off with soap and water. It is not designed for making molds off of skin however.

[mayce1919]

thanks, that was a great help!!!

[hackgirl02]

how do we order latex?where can we buy it online?

[thirsokewl]

or just use the two part mold and save 20 hours of work

[quizzlie]

Wow that is one catchy jingle...

[whitespick55]

i am making a helmet. to be specific a Halo master chief helmet. i bought a non wearable helmet. so i want to make a mold and have a plastic wearable helmet. what specific products will i need and will this method sahown on this video work?

[tambor74]

good video but , evrething in english...is dificult for me because Im not...hey ! Im speack english! jaja?...

[LSLencrypted]

English is the universal language, what did you think? He'd create a video in every single language? He probably doesn't speak the language you speak. And before you start, i'm danish ;)

[jaerperu]

VERY VERY HELPFULL to me!

I am living in PERU and i think this is the best practice way to make it. Thanks a lot!

[FN]

can it be done to object that has no flat surface?? i mean to 2 parts mold??

[tapplastics]

Two-part molds can be made with latex. The process involves making a flange for the first half of the latex. Lay up the latex onto the flange. Once the latex had dried, remove the flange apply mold release to the remaining latex flange and lay up the second half. You will probably also need to create a two part mother mold to support the latex.

[MikeldigraSkyStrider]

Whats a good common non porous surface? And what is placed in the mold to form the copy?

[dylanj619]

ummmm thats cool but ill take the rtv molds, thank you very much.

[matrixdune]

hmm... catchy theme song.. :-P

[valverdis]

ok... realy good
