What you will need:

what you need

Step 1

Measure 30g of resin. It is important that you know exactly how much resin you use as you need to mix in the right percentage of catalyst later on.

Step 2

Mix in your Kulu white. This is a chalk powder that we use to not only strengthen the resin, but to also bulk the resin so that you can make your object cheaper to cast. You can use up to 80% in your resin. In this project I am going to use 20g.

Step 3

Now you need to mix in your Kulu chalk powder. Try not to get air bubbles in, so stir thoroughly without folding the mixture too much.

Step 4

Measure out a small quantity of red pigment (a little goes a long way!) and thoroughly mix this into your resin mixture.

Step 5

Let your mixture stand for at least half an hour, this will help reduce the amount of bubbles you have in your mixture.

Step 6

Take a little of the resin mix, less than 1tsp and scrape it onto the centre of the mould and add a drop of catalyst. Mix with spatula and leave it to set till it is tacky. The reason for doing this is so that you can add a screw to the mould in such a way that it will not be visible from the front.

Step 7

Place a screw onto the resin, which should now be firm but still tacky, approximately 15min, and leave for a further 15min to set. This will hold the screw in place when you finish filling the rest of the mould.

Step 8

Take the rest of your prepared resin and add 2% catalyst to the mixture. It is very hard to judge with this small amount, I'm going to use 1g. Mix slowly and thoroughly so as to minimize the amount of bubbles that will be created in the resin.


Step 9

Working quickly, pour a little resin into the mould. Using your spatula, smear it around the sides of the mould, making sure to work it in to the intricate points to help prevent air pockets from forming on the surface of the mould.

Step 10

Fill the mould to the top and leave to dry.

Step 11

After about 1 hour, the resin should have set and be touch dry. You can now remove the heart from the mould.

Step 12

While the resin is still soft, take a sharp knife and clean off the excess resin around the edge of the item you have moulded to complete your project.

Step 13

Leave for a further 24hrs to allow the resin to set to full strength before you try to use it - in this case we are using our item as a draw handle so it needs to have strength.
