Delightfully waffle-free, clear and succinct explanation, thank you!

@polysil5999 4 года назад

That's so kind! Thank you for your feedback

@GaryMcKinnonUFO 3 года назад

Thanks for this, i'd not heard of Jesmonite before.

@polysil5999 2 года назад

It's fantastic stuff!

@damianevans2321 3 года назад

Hi Paul. Thanks for the question. The material is gypsum or plaster based , so is not transparent ( or even translucent ). It cures a solid creamy colour. I doubt very much if it would transmit much light. Sorry.

@AntonAeonEder 4 года назад

Can the moulding be done with ice in a fridge? Anyone tried an ice mould? Will it harden in a fridge as well?

@utmrxxxx 4 года назад

Very clear video, im gonna try it, but I need one of terrazzo please!!

@polysil5999 4 года назад

we are busy editing a video showing how to do terrazzo, so watch this space for its release when finished.

@polysil5999 4 года назад

The terrazzo video is finished and will be released on Monday 16/03.

Can you add glitter/gold mica to the power portion before mixing?

@rubenstrange 3 года назад

Yup

@lydiahall6410 4 года назад

Hey, thanks for this tutorial. Quick question, when washing the pieces is it safe for the product to go down the sink? I know to avoid this with resin as a comparison. Thank you :)

@cindyliciousXD 3 года назад

Use a sand box to pour the excess and then throw it

@michaelpearson1272 7 месяцев назад

@@cindyliciousXDwhen using a plastic containers to mix jesmonite. Say you cut an old fairy liquid bottle in half to keep for mixing. Then when you've finished poring. And what's left will set in your mixing vessel don't throw it away. I never have. Squeeze your vessel and brake all the stuff left over. It comes of easy. Now you can use all the broken bits to mix with some wet jesmonite and fill your moulds again. So nothing goes to waist. I do this with plaster. Concrete or resin. I've never thrown waste away. It's not landfill

@michaelpearson1272 7 месяцев назад

No. Let it dry in your container. Use flexible plastic. Washing up liquid bottle cut in half to use for mixing when what's left sets. Brake it up and use it in another mix.

@michaelpearson1272 7 месяцев назад

Never pore any chemicals down the sink. Always dispose of them properly. Or find another thing you can do with them. Resins when hard can be recycled into another wet mix. Of plaster. Concrete. Or more resin.

@andyk7967 3 года назад

Can Jesmonite be sealed to make it waterproof? I was thinking of using it to make some soap dishes. Also, can you use micas to colour it?

@powerfulstateofmind Год назад

Yes. There is acrylic sealer. Matt or gloss. And yes, you can use mica too. It just needs a lot more than jesmonite pigment. 😁

@JK-ed3lm 2 года назад

Hello, what PPE is needed using Jesmonite? Just gloves? I'm excited to try this!

@powerfulstateofmind Год назад

As far as I know, yes. Is eco-friendly, non-toxic, water based. You can you a mask as well if you want when you mix the powder...

@hbell1811 4 года назад

do you have any advice if you do need to thin it out? i have a mould with a thinner part and i am worried about the jesmonite not fully getting into it at the double cream thickness

@michaelpearson1272 7 месяцев назад

You don't need to thin it out. Use a wooden kebab scure or cocktail stick to poke your material into all the crevices and then just keep you sticks clean. I do that all the time. I've used jesmonite since it was first invented hear in the UK.

@sarahwoods388 3 года назад

Hi, do you need to seal it with anything to be heat proof/waterproof? Thanks

@damianevans2321 3 года назад

Hi Sarah. There is an acrylic sealer available on our website which helps. However, it is a decorative product that is plaster based. This means it is not designed to be subjected to excessive heat or moisture and would likely degrade over time.

@Lupfield08 3 года назад

I’m having some trouble when I colour my jesmonite mix before pouring. I mix together a colour but once I take it out of the mould it seems like the pigment settles in the bottom of the mould and creates a clear line where it’s settled. How can I fix this? Thank you so much!

@michaelpearson1272 7 месяцев назад

Mix any colour thoroughly with the jesmonite then when you mix the jesmonite plaster make sure you mix all of it properly before filling your mould. I suspect you are not mixing it thoroughly

@Stephh1896 2 года назад

What can I use to seal the product to protect it overtime?

@polysil5999 2 года назад

You can use the Jesmonite Acrylic Sealer. It won't completely waterproof it, but will protect against stains and splashes 🙂

@Stephh1896 2 года назад

What happens if I let it set for longer than 40mins? I’ve read that you’re meant to leave it for 3 hours?

@polysil5999 2 года назад

If left for too long, the Jesmonite can get watermarked. After 40 minutes it is usually hard enough to demould, but be aware it is still brittle at this stage, so handle carefully!

@MrKrukko 2 года назад

the brush can be washed with simple water?

@polysil5999 2 года назад

Yes, Jesmonite is water-based, so you don't need any special chemicals to clean up. Best to clean it fast before it starts to cure though!

@WalkingSideways 3 года назад

This might be a silly question but does anyone know if it can be cast without any pigment? If yes, does it set white?

It's like an off white. 🙂

@MrKrukko 2 года назад

few questions: what's the mass of the final product? (it's needed to convert the volume to cover to the grammes of material to prepare)

@polysil5999 2 года назад

Good question. You'll need 1.75g of Jesmonite for each gram of volume. We measure the volume by filling the mould with water.

@MrKrukko 2 года назад

@@polysil5999 thanks for the answer. Can you pls specify if you mean 1.75g of final JM (includes the water) or 1.75g of JM powder (water to be added as prescribed)

@polysil5999 2 года назад

@@MrKrukko That's total Jesmonite. It comes as a base powder and a liquid, rather than water.

@michaelpearson1272 7 месяцев назад

If you have gram scales it's 50.grams liquid. And 125 of powder. No mater if you mix large or small. Jesmonite is mixed at 2.5 of powder to 1 of jesmonite liquid. By volume

How much jesmonite do you get in the starter kit?

@polysil5999 4 года назад

You get 0.65kg of Jesmonite powder base, 0.26kg of Jesmonite liquid, and 3 Jesmonite pigments each 0.04kg. It is enough so you can use the moulds you get supplied with it, to try it out. Hope that helps?

@dianerevelle3860 2 года назад

Your ‘wash it or chuck it’ doesn’t make it clear that it shouldn’t go down the sink as it could cause blockage/environmental pollution. I love working with Jesmonite, but I often wonder why cleaning precautions are not emphasised. Apart from that, lovely vid:-)

@polysil5999 2 года назад

Hi Diane, really good point. We'll be creating some content with advice on that in the future.

@bemccune7671 3 года назад

Explanation is good, but in future videos please have close up shots on the entire process rather than just the parts where it actually isn't necessary. We don't need to see you talking, much better to focus on the process you're working on so we know what to expect.
