I plan to use a core to fill most of the hollow in the pot, lots less silicone and much easier to demould, just a bit trickier due to the core needing to be suspended above the pot.
Hi, yes, I've used oil based clay before, but wasn't sure it would be strong enough for this since it was so heavy. I also considered adding a foam core, but didn't want to have to figure out how to suspend it. But it's definitely a money saver.
Would it make sense to make a box for the mold to go in for strength, and cut the actual mold down one side as well to make it easier to remove the planter from the mold?
Hi, you can do that, but you will get a line mark on the concrete where the cut is and usually sanding won't remove it. But, just don't use rubbing alcohol to clean the glass like I did because that made it much harder to remove. It will be much easier than it was for me if you don't do that.
You'll either have to do a 2 part mold with the type of silicone I used here- linked in the description, or use a really flexible silicone like in this tutorial where I made a small sphere, but with an opening at the top. artsyprettyplants.com/silicone-sphere-mold/ I'm not completely sure you'd be able to make it in one piece and have the cement release, even with this flexible mold. the customer service at Alumilite is quite good, so I'd ask them.
I'm not sure. I would be hesitant to mess with the ingredients because the silicone may not cure properly. You may want to contact the manufacturer- Alumilite.
Hi, I have the product linked in this article, as well as a tutorial for how I seal them- and when you should and shouldn't. artsyprettyplants.com/seal-a-concrete-planter/
@@ArtsyPrettyPlants thank you! I have a concrete vessel that I want to use for leca/semi hydroponics, so searching for a safe sealer that is 100% waterproof. :)
I'm so glad I stumbled on you're videos. I want to start doing some cement work soon.
Thank you my future project... well explained and narrated Matthew
Wonderfully explained. exactly what I was looking for. Thanks a ton!
This was really useful!

@@ArtsyPrettyPlants I've found a 3D printer to be really helpful with making mould boxes, suspensions for cores and things like that.
@@GaryMcKinnonUFONice! I'll bet. As soon as I win one, I'll be using it for all kinds of things. 😁
WOW! Thanks. I'm exhausted
Thanks for this, just planning a bowl mould. Clay is good for sealing too, and reuseable unlike glue and caulk.
Ah, you mentioned the clay further in. I must stop commenting during watching!

Thank you!!
Can you use this for a resin bowl?
how many silicon did you use?
Great thanks

Thanks for sharing ,, can you please tell me what did u mix to creat the silicon ?
Hi, all the materials I used are linked to in the description.
Looks so great!
Do you have any tips on how to make a large sphere silicon mold for cement pots?
You'll either have to do a 2 part mold with the type of silicone I used here- linked in the description, or use a really flexible silicone like in this tutorial where I made a small sphere, but with an opening at the top. artsyprettyplants.com/silicone-sphere-mold/

@@ArtsyPrettyPlants Thank you so much 🙏
Can the silicone be coloured?
I'm not sure. I would be hesitant to mess with the ingredients because the silicone may not cure properly. You may want to contact the manufacturer- Alumilite.
Hiiii this is awesome! May I ask what product you use to seal the concrete planters?

Hi! What type of concrete mix are you using? Thank you!!
Hi, I used Cement All. Nice and smooth. You can always find more details on my website in the written tutorials linked in the descriptions.
Love it ! Beautiful presentation.Thanks for sharing
Thank you Ahmad!
That amount of silicone is for about 10 molds. Maybe 15.
Well done 👍✅
How durable is this mold? Can we make atleast 100 bowls with one mold?
Hi, it's really durable. I would think you could make over 1,000 if you take care of it.
Love your projects!
Super cool but I think the silicone is way too expensive
Like many things, GE Silicone 1 has doubled in price since 2020. 😒
Bladeless sawzall on a wood board, that'll cure ALL your woes 😉
Great tip! I'll try that on my next project, I do have one of those saws.
🙄
Well it’s true perception is everything. I don’t think this is Clickbait, but if that’s a large planter I’d hate to see what you consider small!! 😂
You call this a large planter ? Lol 😂
Look Superman, for DIY it’s hard to make larger silicone molds due to recourses. So yes, for a DIY concrette/silicone planter, it is a large planter.
