Five tips for casting resin in silicone molds
by Tania of House of Molds
1. Wear gloves when handling molds and pouring resin. Not only do they keep you safe from resin, but they also prevent fingerprints inside the molds. Sometimes these fingerprints can show up on your resin castings. Note: The more glossy the mold surface, the easier it is to leave a visible fingerprint on the mold.
2. Be sure your mold is clean before casting. You do not want any dust or resin from a previous casting inside the cavity. These will cast onto your piece.
3. Take care when positioning your mold. If your casting table has a rough surface or a non level top, your resin piece could be uneven, despite using a perfect mold and top quality resin. You can best prepare a crafting surface for your molds by using a bubble level to check your table levelness.
4. Do not overfill the mold, as to prevent a lot of excess sanding once your piece is finished. In case of resin voids, you can make a second resin pouring anytime by following these rules
*make it when your resin is still at gel stage
*Use the same brand of resin
*pour the next layer before demolding
5. For help when demolding, gently press the mold then add a drop of soapy water inside. Press again and push the object out from the bottom of the mold. This will make resin extraction from the mold easy and quick.
