If you grease the bowl with ordinary kitchen oil (applied thin with a brush) the concrete doesn't stick to the bowl and you can reuse the bowl for another lamp.
Very nice process and project! In architecture school I made a large plaster model of the Pantheon using a similar technique with two bowls. I remember even making the cassettes of the ceiling with styrofoam squares glued to the mold. Might try the same on a concrete lamp project. Thanks for the inspiration :)
You generally do a pretty good job describing each step anyway, but I think you were even more thorough than usual in this one! Very helpful! Thank you!
One thing that you could try for a lot of these concrete projects, is using a reciprocating saw without a blade for the vibrations. It works surprisingly well, although you do have to be careful not to break more delicate molds with them. They are commonly used when pouring concrete sidewalks and such, and they leave a nice finish on the edges.
Ben, for off-the-shelf, Quikrete Q-max mix would work way better than Quikrete 5000...I sent you a message a while back about the virtues of Q-max (sent via your website - not sure if you check this). It is like an inexpensive semi-GFRC mix. In fact, it might be better than the countertop mix since it has AR glass fibers in the mix. You'll get way less bugholes because it has a plasticizer, higher strength, and super quick demolding (a few hours for a project like this)....it really is an amazing product you should definitely check out. At $10/bag it is a great alternative to the countertop mix. I've used it for small countertop projects with success.
Hi Ben, Please could you advise on the countertop mix? We don't seem to have an equivalent in the UK and I'm finding a lot of your tutorials pretty hard to replicate perfectly without a flowable concrete mix that's still high in strength. I'd be grateful for any pointers on mixing this stuff from scratch.
Nice job! Try spreading a thin layer of vaseline on your molds or if you don't have it you can use some vegetable oil too.Makes the demolding a lot easier... If this method leaves any marks you can always sand it.
it will also be a lot stronger if you add fibres to the concrete; one way i can think of is perhaps lots of 2cm lengths of monofilament fishing line? or polyurethane thread if you want some colour.
Any recommendations on the concrete to water ratio when mixing? I tried to make some of these with Quickcrete 5,000 (with stones filtered out) a couple weeks ago and it didn't go well. My concrete was mixed thin enough to pour and I worked to get as much air out as possible. After curing for 24 + hours though the concrete crumbled as I was half finished removing the mold. Tips or advice?
Think an orbital sander without the sand paper against the outside of the 2-liter bottle example would work to vibrate the concrete? I'm kinda liking this but maybe make a couple as table top lamps.
I've made a few book ends out of concrete like this, but they have a concrete dust on them. No matter what I seem to do, I can stop them from producing this. How do I get "seal" them so to speak?
that section of pipe in the bowl could be mounted to a longer rod and positioned upside down (from the way you have it) as a lampshade, right? Is the cement surrounding the pipe strong enough for that? I don't want to hang it.
Exactly - I use a palm sander for all of my concrete projects (counter tops, table tops etc.). Works great - just move the side of the palm sander along the side of the form.
I had the same idea. since there are so many uses for a Palmsander or oscillating sander (diy rust removal bowls) beside the original purpose everyone should have one
Joef Clarin its a modern trend, and concrete is obviously very versatile as you could make all sorts of things out of it with the added benefit of it looking great.
add reinforcement? Concrete has fantastic compression strength but very little tensile strength. that's why you can squeeze it and it won't break, but bend it and it cracks really easy. so, you add metal. even wire (a little thick) can help. make a little mesh inside your mold. hell, make a loose coil that will fit the mold. it will give the concrete a LOT of strength and your stuff won't break. Also keep in mind if you make runny mix, the dried concrete will have even poorer strength. If you want you can add additives to concrete to improve its properties. There is an additive i remember using, it smells very strong of glue, and it makes the concrete a lot more resistant.
that method of vibrating is too violent and the wrong shape; it will add bubbles. you need to use a tube shaped object with a rounded end. It should also only be vibrating slightly i.e. not a lot of movement like the multi tool. I am thinking a phillips vibrating toothbrush would work using an old brush with the end cut off and silicone rubber surgical tubing over the shaft and sealed at the end with a round knob of gorilla glue or something similar.
Go make one then. Us north americans are craftmen. We're good with our hands and we know how to build well, wich makes it logic to see a lot of DIY channels from here. Again, if you want to see a DIY channel from where you are, go make one. I'll go and watch.
I'd like to see YOU make yourself a DIY channel. Listen, UA-cam is an American thing. Now you go make yourself a DIY channel, and its all good. I mean there are plenty of Russian DIY channels. Just because you guys don't have innovation in your country doesn't mean you have to tell other people not to innovate.
looks awesome, but you are doing too much just to make those concrete lamps. it's more easier than this, use oil to not break the big mold and reuse it and many other things
If you grease the bowl with ordinary kitchen oil (applied thin with a brush) the concrete doesn't stick to the bowl and you can reuse the bowl for another lamp.
thanks for the tip! :)
I love everything you make out of concrete, they always come out awesome!
it's always interesting to see which of my graphics UA-camrs watch my diy/woodworking youtubers.
This is such a great idea! I never would have thought it would be so easy to get such a smooth final product

thats awesome , seen you make these lamps before, glad you went into more depth ....looks great
You generally do a pretty good job describing each step anyway, but I think you were even more thorough than usual in this one! Very helpful! Thank you!
thanks for watching :)
So cleverness!!! Love the lights!!
the bottles came out great!
Love this idea! Thanks for sharing xx.
thanks for watching!
This was an awesome video and excellent tutorial! thanks a lot!
This is absolutely going on the list
YESSSSS
Ahh, another use for that neck massager!
Wow this looks great!
Whoa! Beautiful! Will having a more "watery" mix give me more working time?
amazing! love your DIYs 💕
thanks for watching :)
wow whoever marries you will be so lucky. That loft looks amazing.
Your chanel should be called everything made with concrete

I like the little lamp shown at the end very much.
beautiful as always!
Nice Design ...Lg from Germany ...i loveeee concrete
these turned out great 🤓
Very nice design!
I love your channel!❤
Great !!!! Congrats
WOW, this is such a great idea. thanks for making this video. Got some shopping to do.
thanks for watching! be sure the share photos with us when you're done :)
+HomeMadeModern a Concrete company should sponsor you
Super cool, keep up the good work👌
Great project.
You can use a dental lab vibrator to vibrate the concrete
these are nice. got to try it

That was a great project. Thanks. :)
Pretty cool
Nice Job. Thanks for sharing.
nice... just eager to see that stair tutorial :)
Beautiful!
Where do you find the fittings for the lamp? And I mean mostly the cables.
Thanks!
a tip to the molds come out more easily is to apply vaseline on them before placing the concrete.

Hi thanks for the video! I would like to ask - is the lamp heavy and for the inside mould, why not use foam instead for easier removal?
The lamp made from the Perrier bottle mold. Has a similar colour pattern to howlite crystals.
@HomeMadeModern what sort of tool would i use to smooth out the inner edge and bottom of a concrete bottle? will a normal sander do the job?
Nifty project. Could you use Portland Cement with some sand added or maybe some thinset or grout? Cheers! Chris.
you do love hot glue lol. Great vids keep them coming
it will also be a lot stronger if you add fibres to the concrete; one way i can think of is perhaps lots of 2cm lengths of monofilament fishing line? or polyurethane thread if you want some colour.
I still didn't dare to make a DIY for a hanging concrete lamp because I'm worried about the weight. Great project 👍
How heavy are these? I really love your cement diys but I'm nervous everything will be too heavy!
Thank you for the video,
may I ask you how heavy they are approx.?
Awesome
what was it you attached to the end of the oscillating tool to get the bubbles out?
puedes usar grasa para que no se pegue el concreto a los moldes
Great project !! But how much do they weight ?
You are very creative
thank you :)

Think about adding polystyrene beads to the concrete to make the lamps lighter.
Think an orbital sander without the sand paper against the outside of the 2-liter bottle example would work to vibrate the concrete? I'm kinda liking this but maybe make a couple as table top lamps.
Hey what is that drill you are using? is it good for drilling into concrete wall?
I've made a few book ends out of concrete like this, but they have a concrete dust on them. No matter what I seem to do, I can stop them from producing this. How do I get "seal" them so to speak?
Have you tried using a piping bag rather than pouring it in? Maybe a piping bag with some kind of straw contraption
that section of pipe in the bowl could be mounted to a longer rod and positioned upside down (from the way you have it) as a lampshade, right? Is the cement surrounding the pipe strong enough for that? I don't want to hang it.
👍😊
do they still light up a room?
Put cooking oil on the plastick?.
When you paint the plastic molds with olive oil the concert will get out easyer
Hey I want to make a normal lamp and stick local seashells to it then paint any ideas on that
Would it make a difference if say, I put in chicken coop wires in the mold to make it thinner?
can u make this out of plaster instead of concrete?
Why didn't we do things out of concrete at school?
hot glue forever!
i figure a palm sander would be good to get rid of the bubbles
Exactly - I use a palm sander for all of my concrete projects (counter tops, table tops etc.). Works great - just move the side of the palm sander along the side of the form.
got u!
I had the same idea. since there are so many uses for a Palmsander or oscillating sander (diy rust removal bowls) beside the original purpose everyone should have one
why didn't you use some kind terminal instead of insulating tape?
for lighting it does not matter whhhich cable goes where
The designs are vers nice, good ideas. But what are you doing with the wires. Please read up on that. 👍😀
Concrete with sand?
Home depot should sponsor your videos if they don't already
Quem esta aqui pelo canal diycore?
For the vibrating process men stay out of your wife's top draw!
Mats Turnings 😂
I got u
👏🏼🤓🇧🇷
sorry but I don't get it. why concrete?
Joef Clarin its a modern trend, and concrete is obviously very versatile as you could make all sorts of things out of it with the added benefit of it looking great.
concrete aka art stone
why not?
good question..lighter materials setting for minutes get the same look
no pesan como un chingo ?
me: *still trying to figure out how to do laundry*
i love it , what is your Instagram account ?
gosh my lamps keep breaking

I wish that when you are showing diy projects that you slow down the video.
Why does every DIY channel think everyone is from America :/ ..

there's a good amount of bullshit and american exceptionalism here. Fly low, you aren't better than anyone else.
I'd like to see YOU make yourself a DIY channel. Listen, UA-cam is an American thing. Now you go make yourself a DIY channel, and its all good. I mean there are plenty of Russian DIY channels.

use one of these next time bauhaus.bg/userfiles/productimages/product_7418.jpg
looks awesome, but you are doing too much just to make those concrete lamps.
it's more easier than this, use oil to not break the big mold and reuse it and many other things
Taking a picture of the wiring makes no sense. It wouldn't matter if you switched colours as it's AC current..
look at a product called hypertufa and see what happens
