Activity 51:  Cement Architecture

We have worked with cement before - it is an incredibly exciting medium to work with (I think) as you can make nearly anything with it, with a great look but above all; function!

Initially I wanted to make a cement house, by making a mould out of cardboard, pour in the cement and et voila you have yourself a bookstand.

But then I broke a table and thought I would use the cement to fix the table and show you the mould making process at the same time.

Cement art is a dirty process in which the setting up and tidying up takes more time than the actual art making.



  • Cement (quick dry or normal)

  • A bucket for mixing

  • A wooden ladle or anything sturdy to stir with

  • Gloves

  • A mask

  • Ideally safety glasses

  • A board to work on

  • Waterproof tape (electricity tape)

  • Scissors

  • Cardboard to sculpt mould with


  • A sink nearby

  • A big surface to work on and let everything dry on

  • Windows to open up and allow the air to circulate through



Step 1.


Start making your mould by bending the cardboard into the shape you need. Make sure the cardboard is straight at the bottom end, as it will have to match up to the cardboard you are attaching it onto – perfectly. Any gaps means the cement will go through it.


Step 2.


Tape down the cardboard into your mould shape. The tape is best on the outside as it can leave a marking on the cement art when it is left in the inside. It may also add to the effect- so think it through.


Step 3.

Once you are happy with your mould you can start mixing your cement. Read the instructions on the cement box.

I also think of it as pancake mix - not to thick, especially not to thin (if it looks watery, the cement will not be as strong).


Step 4.

Start pouring the cement into the mould. If you can lift it; gently shake it to get the airbubbles to come to the surface.


Step 5.


Always as a bit more cement than you think as the water will surface to the top and will not become a cemented part.



Step 6.


Leave to dry fully. The time of this depends on the size of project.

Tidy up your workspace immediately and never pour any cement down the drain.


Step 7.


Once dry, start cutting and peeling off the mould.


The video below will show you how Vanessa did this.

That’s it! 😉


If you make one of these, please send us a photo - we would love to see!
