It's time to get back to a routine and school! Nope, not another mask pattern,…
Once you really start to look around there are so many ways you can make things, especially concrete things! This project can’t be much easier; it’s probably easier than making pancakes! Soda cans are everywhere, and can make cool shapes when wrinkled. (lightbulb-over-head-moment) Why not use them as a disposable mold?! Ta-da! Anyone can do this! Ok, I’ll soon have to join ‘concreters-anonymous’…
I am using a quick setting concrete again and using the same concept as my other slush poured heads.
To make the Simple Soda Can Concrete:
You will need:
- soda cans (I make a few at a time)
- RapidSet Cementall
- Rubber gloves & Dust mask, gloves for hand protection
- Mixing container, utensil, water
- strong scissors or tin snips
- pliers of some sort
- stick or broom handle (will not be destroyed)
- acrylic paints to finish
Step #1: Get the cans ready
There is something about the engineering of the bottom of the can that makes it so strong. To make removal easier later on I found that pushing the bottom to bow outwards helped. Force a broom stick or other stick into the can bottom until it ‘bumps’ out the bottom.
Tin cans are quite thin and can be cut quite easily with some scissors (just don’t use your best ones) Protect your hand with some gloves as the edges become sharp. Cut the top off just after the top ‘neck’.
With gloved hands, manipulate the can til it has a nice amount of dents. Have fun with it, it will hold it’s shape.
You can cut some small slits into the top rim to make pealing back later easier as well.
I get a few ready to do at a time.
Step #2: Mix the concrete
This mix is quite fast setting so you want to be ready. It also mixes a bit differently than most mixes at about 1 : 4 ratio of water to mix. I add the water first, not adding too much since it readily absorbs more mix than you’d think. (like working with icing sugar)
The consistency should be on the thin side, so that it will pour and flow. It does also tend to just thicker after a half minute. Mix again until flowing.
Pour some into a can and rotate to coat the insides. Slightly tap to keep it flowing. If you had mixed a lot you can pour some into another can. It will stop running after a few minutes so slowly rotating will help stop it all from gathering at the bottom. It isn’t that difficult as you can see inside. The top edge can be irregular as well so don’t be fussy.
Being an artisan isn’t about perfection, it’s about managing media to work with you. You’ll be much happier of you just let it have it’s characteristics.
Turn slowly, it will set, I promise you. (10 minutes, tops)
There you go… Wasn’t that hard was it?! It may be quite thin depending on the consistency of the pour. Within the hour you can add another layer of pour to strengthen. Since this is a high strength mix it can be as thin as 3/32″.
Step #3: Taking it out of the Soda Can
So, you didn’t have to make a mold, but now you will sacrifice it. Rip some strips down the sides.
My bad! No gloves, but I was using the pliers with that hand.
It is easiest if you make some slits in the top edge to tear strips downward. Work to the bottom as it is the most stubborn part. Tear across the bottom to finish the removal. (the dented out bottom has made it easier)
Since the surface inside is shiny, it casts very shiny as well. It is also very strong for a thin pour. They are quite lovely already. Imagine some marbeling with colour mixing…
Step #4: Finishing your Simple Soda Can Concrete
If you know me by now, you know that I think part of the charm of concrete is the natural finish. So, by all means, just leave it natural… Or give it a slight finish.
Yes, you guessed it; I dry brushed with some metallics. That adds a new metal look and is subtle. It will have everyone scratching their heads wondering; ‘what the heck?’
Ok, so how cool is that?! Made from what you throw away (I mean recyle)
The details that it picks up is great.
Make a few, so quick and cheap. I bet this could be developed into something even more elaborate (there goes my ‘concreting brain’ again…)
