Joint compound is fine to do sculpture art on canvas, etc. It will hold up just fine. I use it all the time in my art. I form my art with it on a canvas, get the shapes I want then I sand it lightly after it drys. Then i gesso it, then seal it with a varnish or medium, then paint it the colors I want. AFter that I seal it a couple of times with a clear gloss or matt varnish, holds up fine.

1 part white latex paint to 4 parts joint compound= a much better representation of molding paste. Especially if you add acrylic paint to it or paint over it when it's dry. molding paste is still better, but if you're poor like me or run out and need a quick substitute. This'll do ya.

For any that need to know, Joint compound is not quite Spackling Joint compound is for using at installation for sealing joints along with the use of tape, not gonna be as good for repair as Spackling is because Spackling is gonna accept paint better, and it's white. Some even goes on Pink and dries to white. Compound sticks to other Compound or the substrate. Compound doesn't stick as well to a painted wall. But if you do another layer, your spackling is going to stick better from that point on Good thing is Joint compound can be bought in a powder form or ready mixed And Spackling can be bought in a small amount for like $4 US. Then you can test it.

I use joint compound all the time. Once you paint it and varnish it, it looks great.

Also another thing you could try is use the Acrylic Joint Compound and add an entire small tub of the Commercial Molding Paste to it (ie. Liquitex or Golden). This might encourage longevity. I say try anything to produce your own. I'm no Scientist, but I love tinkering around, and I have YET to have a failure! Artists materials are vastly overpriced! Most Artists are poor, so if you can make your own .... shoot, do it!

I have not yet tried adding any sort of texturing media to a painting, so to have this information as a reference before investing in a product is a blessing. Thank you for this video.

Even years later this is SO useful. Thank you for the review, exactly what I was looking for!

I use joint compound to experiment with or practice techniques, but if making something that needs to stand the test of time I will invest in the good stuff. There’s no replacement for artist-quality mediums, but they’re WAY too expensive to play around with.

You can also add some water to the drywall mud to get a smoother consistency ... and luckily I do t know to many people that would dare go up to someone’s textured painting and start scraping it.. if it has paint on it or mixed with it... it’s not going to crumble or go anywhere .. u less ofcourse if you start trying to scrape it off.. otherwise it is a great substitute... if you have a little hand held immersion blender... that does great for mixing your paint with drywall... adding sand, whatever you want... just add a little bit of water to get the right consistency that you are seeking.

very helpful! and I love how you have started organizing your studio

I have been in a quandary about this as a budding artist. Your video was an answer to a prayer, and has saved me from teary mistakes. Thank you! (Of course I subscribed!)

Thanks Cinder block; I just bought golden's light paste because I'll be using it on fabric. It was demonstrated on National Quilters site.and I'm inspired. Good of you to take the time to clue us in.

works fine if you gesso the canvas first and then use it sparingly and not too heavy that it fall/flakes off. After it is all dry you can also spray protect it with eurathane

Tip:- Acrylic joint compound has all the same properties as any “Artist” Modeling paste. No problem as mixing in Acrylic paint to it as it is flexible and has the same adherence to your fine art support as the normal art acrylic mediums on the market....it is much cheaper to buy at hardware stores which is the big plus...just make sure is does say Acrylic joint compound on the package. Cheers.

Awesome tips! Thank you for sharing honey! Happy New Year! xoxo

JC will work on a board, but not on canvas or any flexible substrate. JC dries rock hard and will brake off if the canvas flexes for whatever reason like moving, too much of a chance to take. I use adhesive caulking compound which dries hard but does not become brittle.

Longevity is the key word. This is the answer to the question I have been searching for. Thank you.

There is an artist that uses joint compound mixed with glue and some cellulose, and it makes a really fine sculpture product over an armature for bigger projects, where a molding paste would not work and be way too expensive

I'm not just painting this stuff on, I'm making little decorative medallions with it for pastiglia e mucchi or stucco decorated late medieval-style boxes. Golden brand gesso and coarse molding paste are fun, but expensive. We have a lot of white acrylic paint we can mix with the drywall compound, and some waterproof wood glue, and plaster. I spent money on these things, and it would be great to use them up. I could make a ton of gesso decorations (a layer at a time) before running out and having to buy art supplies. The main thing I'm worried about is things being waterproof.

Thank you, I really needed this review :)

Haha...love the way you brought the bucket up with such such naughtiness

Awesome vid, informative. How can we make 'alternatives/DIY' pastes archival? I hope there's a book about DIY archival quality mediums.

Very helpful video. Thanks for sharing it!

Thank you for this demonstration!!! It was the best I’ve found!

Thanks for your thoughts. I make my own modeling paste out of baby powder and gesso (which I also make) and sometimes I switch up the powder with baking soda or plaster of paris with school glue and acrylic paint..

I would also add some 'Gum Arabic' which might help it to stick to the substrate.

Thank you ! I've been so confused for months 😁

I use joint compound all the time. I love it!

I've seen it mentioned already, amongst other additives but I feel like mixing in some pva (Elmers) alone would yield a good substitute. Maybe.

you can ad plaster of Paris for more strength and won't crack

I use Plaster of Paris, it's never failed me yet.. way cheaper then the products on the market..

LOVE this!!! What if you add white glue with the joint compound?

Appreciate any help I can get. bought what we call drywall paste (not sure if that is joint compound or sparkle ) in a premixed tub. Lovely and smooth but it does not hold shapes it droops. I want something I can sculpt with so I can make raised petals or birds wings or something that lifts off the canvas not just stencil etc. It also drowns out colour so that would be costly if working with colour unless applying on top. So after searching it suggests using plaster of paris which I did and added some to my drywall paste. Yes, it thickened it but was grainy and not buttery and also dried way too fast. I am at my wits end trying to find something that actually works that is not a fortune. I read add glue and add this that and the other but nothing seems to produce a good paste. Do I really have to pay for commercial paste?

I would think if you use joint compound, once you paint over it, it should hold up pretty well as long as the canvas doesn't flex much.

Your thoughts on lightweight wall spackle being used to build up form and texture underneath acrylic modeling paste?

Nice experiment thanks for sharing 👍🏼

This was very helpful thank you

joint compound will hold up you can prime it after then paint it with any kind of paint i use it all the time also you can do clear coat of resin as well the only thing that i would sugest is gessoing if you using it on canvas or any type of art work

Really helpful. Thank you.

Add a glob of Tacky glue to your drywall compound and it works great.

What if you were to mix equal parts or a 2 to 1 ratio etc etc, how will that work?

Thank you! Excellent explanàtions

I enjoyed this video 👍🏽

Thank you! for being honest🙂

Would either product work on patching a garden statue. My stone dragon is either painted or glazed with a terra cotta (clay pot colored) surface that has worn away and chipped in a few places. Not sure if it is stone or concrete underneath. I also have to reconstruct the top portion on one ear. Have you any suggestions on what kind of product to use, including a glue that adheres to stone surfaces. I have had good luck with acrylic paints for outdoor figures, but not much experience with repair work. Any help would be greatly appreciated.

can i use joint compound or silicone caulk or spackle in silicon molds to make embellishments?

Thank you!

Gr8! Thanks!

Hi I wanted to know if I wanted to put the joint compound on a mirror how could I get it to stick?

What if you added acrylic polymer to it?

Hi. Can you recommend please a joint compound in Italy or maybe analogue of it. I can't found it here🥲 Thanks😊

So, get either type of paste or just the regular?

Hey, they make an acrylic spackle, by red devil. Maybe you can make a vid comparing this with modeling paste and regular spackle

The joint compound shrinks after drying.. 😑.. I wanted to make sculpture flowers.. But this compound shrinks and cracks... 😒

Hi Nice Educational Video. I am one of your Subscriber. I have a question: Some Artist are doing their own Modeling Paste using this one example mixture of Baby Powder, Acrylic Paint and Wood Glue 1. Now in Jointing Compound - If I will add White Acrylic Paint Plus Wood Glue to the Jointing Compound does it will have the strength of the Regular Artist Modeling Paste? 2. I recently encountered in the internet the Sargeant Brand of "Sargeant Sculp It". Can I use this in replacement of the regular modeling paste? Hoping for your reply on thigh S matter. More Power

I actually something funny, I see that u have a cinder block there (Its for fire place fuel right?) You can actually make it out of a couple of bricks of wheet bix and about 3 tablespoons of raw oats, mix with it water, then dry it crack dry in the microwave, and it makes really tough cinder u cant break it by hand!! haha. needs to be varnished tho cause its water prone.

thank you.......

Thank you

Ok, scratch that one! Thanks.

thanks for the video. What is the verdict? Would joint compound crack on a large canvas?

Thanks ) Patreon is great if you can take it out of your Art Fees which mine tend to escalate!

Hi Ben . I prefer molding paste . but I use the joint compound or homemade molding paste on occasion . I add regular Elmers glue and white paint to it . What is your opinion of these additions . And no I dont do anything professional . Thanks

I saw your shirt! ❤️ From Wild and Wonderful West Virginia

What’s the difference between joint compound and plaster?

Thanks

Don't' think I would be trying to scrape an art piece like you are. ...And many layers of acrylic paint over the joint compound will render it stronger and dust free. Varnish adds extra protection and durability as well.

mixing my own home made modeling paste from early 1960s :)

Woke great in mow media work, stencils,

Definitive answer = maybe?

can you cast a sculpture with it?

I use joint compond for outline on my hardboard but it breaks? Why

In conversation is totally wrong we deal with mortar in the brick outside the mortar depending on the type does seal up solid but like anything if you hit it with a hammer it's going to break, why would you take an art picture and hit it with a hammer to see if it's going to break duh and taking joint compound and doing artwork has made it so artist can afford their medium, someone figured this out took joint compound added a little acrylic mixture put it in a small jar Walla to get 20 bucks a pop don't be naive you can use joint compound you can smooth it with a brush and water or even when you're done you can sand it lightly I smooth it with brush and water-oh, it's wonderful to work with on canvas don't get it too heavy because you're thin out the compound and then it will crack

As a homeowner, art teacher, and artist - if that is the conclusion what does that say about our walls?! And no one should be trying to damage artwork with texture!

Mix some PVA with it, It makes it less inclined to powder and makes it smoother. No, it may not last a 1000 years, but I'll settle for 995.

Could you help me how can mettalic it

Sorry, you are WRONG! I cover mine with gesso. After that it acceptes acrylic paint...And any other toppings I add.♥️

I found that joint compound cracks..its not smooth.

Definitely (pause)..... maybe hahaha ha definitely waiting for an answer hahahahaha

Why do people talk about longevity issues when they have no way to experiment such issues on joint compound. What do you do, wait twenty years and see what the results are? If you leave the joint compound by itself and it turns into powder when scratched, what happens if you add such things as PVS glue, acrylic paint and even some type of sealant? Anselm Kiefer uses dry twigs and straw for his work, for Christ's sake...

i would imagine , if your on a budget, that if you clear coated the final product, it would work out , but if you are selling the product, that's kinda left handed and dishonest

Very interresting point there ...but if you learn to master mixtures plaster will do the job most of the time in less your a rich Artist or have specifics to respect.... and enjoy keeping your money in your pocket...i hope i wont get Plastered for this comment...:)

joint compound will crack if you use on canvas as the canvas has flex in it.. If you use on a board surface it will do fine.

by the way, acrylic never really cures, it just dries

Thanks
