Pour silicone with the right tips - this is how it works

You can make very beautiful and practical shapes from silicone. In order for the molds to achieve their desired look, you need to pour the silicone. Read on to find out which tips will help you:

  • Material: The material you need to cast silicone is silicone rubber. The silicone is prepared in such a way that it is already liquid and can therefore be poured into molds. Be sure to buy the rubber in two parts. The two components together make up the finished silicone.
  • Mixing: The mixing ratios are indicated on the packaging, you should orient yourself towards this. Make sure that you adhere to the mixtures as closely as possible, otherwise you will get a poorer quality. You can use kitchen scales, for example, to weigh the quantity.
  • Preparation: You have to pour silicone into a negative mold, which is the later shape. This shape can be made of wood, plaster of paris or stone. Since the materials for the negative form are very absorbent, you should treat the surface beforehand with a release agent spray. This prevents the silicone from being drawn too much into the material of the negative mold.
  • Casting: You should only cast your silicone parts at room temperature or at temperatures around 20 degrees Celsius. If it is too warm, the material becomes too fluid, if it is too cold it can clump together. Once you've poured the silicone into the mold, let it harden. Depending on the manufacturer's information, this can take up to 24 hours or longer. Tip: Let the mold rest in a place that is as warm and dry as possible.
  • Demoulding: Only take your silicone mold out of the negative mold when it is absolutely dry. Otherwise, it may stick to the edges and damage your shape. You can try it for the first time after 24 hours of drying time. If you then cannot easily remove the silicone, you should wait a little longer.
  • Tip: start with small and simple shapes. Because preparing the form in particular requires a lot of practice and experience. You will also succeed in demolding significantly better after several attempts.
