You will need:



  • cake of your choice covered in sugarpaste
  • cake board covered in sugarpaste
  • Rainbow Dust Metallic Food Paint in your colour of choice
  • Thick sable brush
  • Rainbow Dust EasyCover sponge
  • Paper towel
  • Ribbon to decorate


Shake the paint before use and pour out an adequate amount onto a pallet or plate (5 or 10ml should be plenty). We have also covered our cake board with sugar paste. Not everyone does this, but this step is also useful for painting the very base of your cakes edge. Taking a thick sable brush (either No.6 or a flat edge approx. 8mm) and dip it into the paint, soaking up a generous amount of paint. Apply this at the bottom of the cakes side, where it meets the cake board (fig. 1)


Continue all the way around the cake until you meet up with the point where you started.(fig. 2) Do not worry about being neat as this will be covered up by the sponging technique.


Take your EasyCover Sponge and soak it in water (under the tap). Squeeze dry and if possible make it even dryer by squeezing it in a paper towel. This will leave the sponge very soft but without any excess water that could dilute your paint.


Take hold of the sponge and dab it into the paint on your pallet/plate until the sponge absorbs a good amount of paint. (do not dab it until it is dripping, this is far too much) Then, simply use a gentle dabbing technique to apply the paint to the cakes surface. (fig. 3) Do not press too hard, simply apply the paint with many gentle touches. As you sponge over the edge that you initially brushed as paragraph 1, you will notice that the dabbing of the sponge hides any brush marks and creates a seamless covering.


Continue until the whole cake is covered (fig. 4).


Allow the paint to dry and then continue as per your design. We have added 2 pieces of ribbon to finish off the cake. This is then ready for the top decoration. (fig. 5)


You could skip paragraph 1, but there is a greater chance that you would not be able to push the sponge into the joining edge of the cake and the cake board. This could result in
white spaces in your paint.

Tip 1

To create a deeper covering, wait until the first coat is dry and apply a second coat of paint by repeating the dabbing process.

Tip 2

It can be a good idea to cover your cake with a complimenting colour to the paint. For example, if you are going to cover a cake in silver paint, then it is a good idea to use a grey sugar paste. (Yellow sugar paste for gold paint, Blue sugar paste for blue paint, etc etc). This is not essential as we have shown in our mini tutorial, however, it does reduce the need for 2 coats of paint.
