Concrete Casting For Beginners

[@KharaokeTube]

I was gonna skip video because I didn't think it would be for me. I only do small concrete sculputres, just getting into it and currently making molds from foam, cardboard, etc. But I learned so much!!! This was so easy to understand and the demonstration was easy to follow. Thank you!!

[@GlobMarble]

Glad I could help!

[@HowRay]

It’s obvious you’ve done this before. Nice video. BTW, that is a beautiful molded panel. Love that pattern !!

[@GlobMarble]

Yes! Thank you!

[@jimsimpson2393]

Thanks for your very clear, succinct descriptions and visually clarifying images. Excellent!

[@GlobMarble]

You're very welcome!

[@compubyte2010]

I don't have room for a vibrating table, But what I did was go out and purchase a double ball vibrator for backs and shoulders with a handle. I just put it under the item and on the sides. and run it along it and works like a charm !!! for molds and concrete pavers I make etc.

[@GlobMarble]

Awesome!! If you'd like to upgrade, you can create your own vibration table for not too much money. We have an old video on it- kzbin.info/www/bejne/jnmqn3qrjMtrqZo

[@tswhite7929]

You know your shit. Thank you. Insider tips always helpful. Great Job

[@GlobMarble]

Thanks!!

[@agomodern]

Literally, the only place I can find that says you don't need gravel is on this video. Just the answer I was looking for.

[@GlobMarble]

Glad I could help!

Beautiful thanks for you hamza from Algeria

[@GlobMarble]

My pleasure :)

Super interesting. Thanks...

[@r.jbirmingham9702]

you should try spraying the sealer on nice job

[@GlobMarble]

Sprayer is also a great option!

It looks like this technique would work pretty well for pavers. If I understood your technique adequately, it looks like you just use sand without and gravel or stone for aggregate. Would this approach be strong enough for pavers? If so, what would you consider to be a minimum thickness for a 12” or 24” square paver without any reinforcing?

[@GlobMarble]

It works great for pavers and stepping stones, check out some of our other videos like this one kzbin.info/www/bejne/oJe2e4JppKd4aMk

[@SVSunnyJim]

Thankyou, concise presentation.. 👍

[@GlobMarble]

Glad it was helpful!

[@correocarlosgarcia]

Can you add marle powder and white cement for a better looking appearance? How much of each one and sand?

[@MadMax-op8pl]

I was wanting to use cement in a slip cast mold, like for ceramics. can I use a similar method?

[@GlobMarble]

Yes you can!

[@sharonmitchell6296]

Looks good

How is it the concrete became black I did not see you adding pigmentation

[@GlobMarble]

That is what freshly casted concrete looks like. It gets lighter as it cures

[@kimberlysmith4997]

FANTASTIC!!!!

[@GlobMarble]

Glad you like it!

How do you make sure all your tiles are exactly the same thickness. 1 tile per 24hr per mold is very slow process. Is their a way to speed this up. Also how can you achieve very smooth surface. I can see dimples on the tiles. Which in this particular case is no issue. But in other tiles it might be an issue.

[@GlobMarble]

The tiles will all be the same thickness if they are poured on a level surface and screeded at the top of the mold. You can add CSA which is a fast setting additive for concrete to be able to produce 2 molds per day at best. Most large production facilities just use many molds to mass produce their stones. You could cast with plaster of Paris which will let you cast up to 10 a day but the stones will be much more brittle because they are not made of concrete. By dimples do you mean bubbles? Bubbles are removed by vibrating the concrete. We sell vibration tables, and also just the motors if you want to make your own table.

[@Z-add]

@@GlobMarble by dimples i meant holes on the stone surface.

[@GlobMarble]

Yes that is what I was talking about

[@airbornearchitect7062]

cool video ....

[@GlobMarble]

Thanks!

[@DarthLeopard]

I'm actually watching this because I got a job offer as a polymer concrete caster at a factory and had literally no idea what to expect. Would this be more or less what I should expect there?

[@GlobMarble]

Probably but with way more expensive machinery :)

[@ferencbekesi6197]

Very good video! How you calculate how much concrete need to use for the mold? This can be your next video subject ;) thank you

[@GlobMarble]

You don't need to calculate anything, we've already done that for you. The precise measurements will be in the description of the product on our website :)

[@prakashgprakash4681]

Nice....

[@GlobMarble]

Thanks!

[@danielbodily6087]

How do you make white concrete

[@GlobMarble]

Using white cement and white sand will give you the brightest white, or you can use titanium dioxide pigment. You can learn more about that here- kzbin.info/www/bejne/aKWqfWybmM13hNE

[@khanns2529]

Couldn't find next part of the video in playlists, videos & Description. Can you post the link for next part of the current process?

How many square feet is the mold?

How Can I Maintain The Original Color.. The Colors are fading each day after demolding

[@patglenn7762]

What did you stain them with?

[@seifalbeshti9497]

I add pigment to the mix 70 gram for each 1 kilo cement

[@GlobMarble]

The color always fades after demolding, because the concrete is losing its moisture. There are two ways of keeping the color dark. The first is demolding after one week, but the downside to this is you have to wait, it will be much harder to demold, and the mold will not last nearly as long as usual. The second option is adding a sealer which will give the concrete the same color as when you wet it. Here are our sealers- globmarble.com/decorative-concretes/concrete-sealers/

[@patglenn7762]

@@seifalbeshti9497 What Globmarble said.... A wet sealer will keep the colors looking bright.

[@upalinatureboy]

Hello sir, I am from srilanka, manufacturing wall claddings using concrete. Still having a problem to achieve black color only on the the surface of the claddings. Please give me a simple advice. Thanks

[@GlobMarble]

You should use our 8084 pigment and mix it at 2 lb of pigment per 94 lb bag of cement. If that is still not black enough, you can add a sealer to make it darker- globmarble.com/concrete-color-oxide-pigment.html

Where can I get those rubber

You can check the description of the vide, I listed all of the products I used here :)

very nice i like

[@ben9433]

Might try the washing machine, it vibrates the entire house when it spins

[@Sejo-writer]

😃😃😃💪

[@melanieaway]

if you soaked it in a water bath for a week to a month it would just get harder. This is gorgeous

[@GlobMarble]

The water bath is a common DIY method but for large scale production people create humidity rooms because they take up less space. A cheap one to do it get a shelf you can stack a lot of the castings on, spray a bunch of water all over it and cover it with a trash bag.

[@doczenith5491]

You can now buy additives that cure the cast in a week or two.
