Want to make your own silicone moulds for your Resin Art projects? Then you've come to the right place! In this article, we explain step by step how to make your own moulds with RESION silicone moulding rubber. We discuss the different types of silicone and provide tips for making the perfect Resin Art mould. Read on and discover the world of silicone moulds!
Silicone moulds are ideal for making Resin Art because they are flexible and reusable. In addition, epoxy and polyester do not adhere to silicone and they are resistant to high temperatures. Moreover, silicone moulds are easy to clean and maintain, so you can use them again and again for your creations.
At Polyestershoppen, you will find various types of casting rubber from the RESION brand. The range mainly consists of addition cure silicone in different shores: Shore 8, Shore 15, Shore 25 and Shore 40. The higher the shore, the stiffer the silicone. Shore 8 is therefore the most flexible casting rubber and Shore 40 the stiffest variant. Want to know more about the different types of silicone rubber? Then read the article "Types of flexibility in silicone casting rubber".
To make a silicone mould for Resin Art, we recommend using RESION Silicone casting rubber Shore 15. This flexible silicone features good tensile strength and elasticity. This makes the mould tear-resistant and very suitable for multiple use. The casting rubber is also resistant to heat and shrinks minimally.
Before you start making your silicone mould, make sure you have the following supplies to hand:

Thoroughly clean the object you want to use as a master and make sure it is free of dust and dirt. Then apply a thin layer of release agent to the object to prevent the silicone from sticking to it.
Place the master object in the mould shape, making sure there is enough space between the object and the edges of the mould. If you use a homemade mould, make sure it is sturdy and leak-proof.
Weigh out the required amount of silicone casting rubber and mix it according to the instructions on the packaging. RESION silicone rubber has a mixing ratio of 1:1. This makes the product super easy to use and you don't have to think about the correct mixing ratio. Pour component A and B into a mixing cup and mix the components well. Be careful not to mix too quickly to avoid an abundance of air bubbles. We recommend mixing for at least 3 minutes and also scraping the sides and bottom of the mixing cup well.
Pour the mixed silicone slowly and evenly into the mould. Start in a corner and then cover the object completely. Try to prevent air bubbles by pouring the silicone in a thin stream. Have you discovered that you haven't produced enough silicone? Then make some extra. Silicone also adheres excellently to old layers of silicone.
Do you have a gas burner at hand? Then use this carefully to remove the air bubbles from the silicone. Don't have a gas burner? No problem, just gently tap the sides of the mold to release any air bubbles to the surface.
Now let the silicone harden. RESION silicone rubber is tack-free after approximately 8 hours. However, this is highly dependent on the ambient temperature. At lower temperatures, curing can sometimes take a little longer. Has the silicone not completely hardened after a few days or are there still wet spots? Then something went wrong during processing. Unfortunately, in that case you will have to start over.
Once the silicone has fully cured, carefully remove the mould and take out the master object. Your silicone mould is now ready for use and you can now fill it with epoxy or acrylic, for example!
