Instructions in 9 steps Paint the concrete star with the acrylic marker and hang it up with organza ribbon.
Besides the articles listed below, you also need: Cooking oil, sieve, support out of Crepla or cardboard
And this is how it works: 1
Step 1
To start the preparation, put the star-shaped casting mould on a solid and even surface, so that it doesn’t wiggle and coat its inside with cooking oil.2
Step 2
In order to remove the larger pebbles from the cement, you should sieve about 120 g of the cement powder before mixing with water, through an ordinary household sieve.3
Step 3
Pour about 13 ml of water (once the cement is sieved, the mixing ratio is changing according to the instructions on the package) in a plastic bucket and then gradually add approx. 80 g of the sieved creative-cement powder. Stir this mixture with a craft wooden stick until an uniform and castable mass is obtained.4
Step 4
Fill the prepared big star-shaped casting mould with the casting compound up to the desired height. Let the mixture rest for about 1-2 minutes. Thereby tap repeatedly and slightly onto the mould to release any air bubbles from the cement mixture.5
Step 5
Let it dry out overnight.6
Step 6
Now, you can demould the cured object by removing the scotch tape and upturning the wooden skewer. Turn the star-shaped casting mould around and lay it onto support out of Crepla or cardboard. Tap the star-shaped casting mould carefully on your support, so that the star out of cement becomes entirely detached from the mould.7
Step 7
Allow it to harden. The curing time varies depending on the size and the temperature (one to several days).8
Step 8
Small burrs and irregularities can be quickly & easily grinded with sandpaper. The hanging up hole can be reworked as required with the bead reamer.9
