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 silicone moulding rubber from RESION. We discuss the different types of silicone and give tips on how to make 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 stick to silicone and are resistant to high temperatures. Moreover, silicone moulds are easy to clean and maintain, allowing you to use them again and again for your creations.
At Polyestershoppen, you will find various types of casting rubber from the RESION brand. The range consists mainly 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. 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 heat-resistant and has minimal shrinkage.
Before you start making your silicone mould, make sure you have the following supplies to hand:

Clean the object you want to use as a master thoroughly 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 form, making sure there is enough space between the object and the edges of the mould. If you use a homemade mould form, make sure it is sturdy and leak-proof.
Weigh the required amount of silicone moulding rubber and mix it according to the instructions on the packaging. RESION's 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. Make sure not to mix too quickly to avoid an abundance of air bubbles. We recommend mixing for at least 3 minutes and also scrape well along the side and bottom of the mixing cup.
Pour the mixed silicone into the mould slowly and evenly. Start in one corner and then cover the object completely. Try to avoid air bubbles by pouring the silicone in a thin stream. Find out that you haven't made enough silicone? Then make some extra. This is because silicone also adheres excellently to old layers of silicone.
Do you have a gas burner handy? Then use it carefully to remove the air bubbles from the silicone. Don't have a gas burner? No problem, tap the sides of the mould gently to allow any air bubbles to rise to the surface.
Now let the silicone cure. RESION silicone rubber is tack-free after about 8 hours. However, this is highly dependent on the ambient temperature. At lower temperatures, curing may take slightly longer. Is the silicone still not fully cured after a few days or are there still wet spots? Then unfortunately something went wrong during processing. Unfortunately, in that case you will have to start all over again.
Once the silicone has fully cured, carefully remove the mould from 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 Acrystal, for example!
