How to Make Resin

How do you know which Silicone Molds For Resin are right for you? In order to create beautiful, intricate jewelry or other resins with epoxy resin or other hard plastic polymers, it's important to have a good, strong negative mold. These come in many, various designs to purchase. When, however, you just want to build something for yourself or just want to try out special, individualized forms, then a silicone mold can be very simple to make. Here are some tips and tricks to follow when buying a mold for your own use.

First, you should decide on a good, sturdy wooden frame to support the entire unit. Most Silicone Molds For Resin bases are constructed using a hand-formed plastic core to secure the two pieces of board. This isn't necessary for all Silicone Molds, but it can be very handy for some models. Once the frame is prepared, the pieces are put together with dowels and secured with brad nails or wood glue. The thickness of the foam core will determine how stable the whole structure will be while it's being molded. A thick core will also make the mold more durable.

Next, check to be certain that the two pieces of board are leveled and attached tightly at the bottom. This allows the Silicone molds to dry at room temperature without any moisture, which is critical if you are planning to use the item in a humid area. Leave the wooden frame on the bottom of the blank resin tray while the foam is still relatively warm; this allows the resin to set quickly and properly.

Now it's time to add the desired amount of Resin to the bottom of the plastic mold. Apply as much silicone as possible using a spatula or brush. The more Resin you apply, the denser and more durable the finished piece will be. Once you're satisfied with the density of the resin, cover the plastic mold with clear plastic to keep it from drying out. Avoid allowing water to get into the Silicone Mold, as it will affect the final outcome.

Painting or applying a clear coat of finishing material to the silicone mold can help it last longer but is not always necessary. If no paint or primer is used, the easiest way to protect your new Resin sculpture is to line the bottom edge of the mold with a thin layer of clear polyurethane or other primers. This is best done while the item is still slightly cold, as the harder you allow the item to cool, the longer the primer will seal and protect the piece. Allow enough time for the primer to solidify before using. Using clear resin products will also help it reflect light, which creates a frosted look that is very attractive in fine art and furniture pieces.

Another way to protect the newly-made piece is to let the item dry completely in an open area, such as a kitchen sink. This will prevent the liquid from seeping inside the Silicone molds and affecting the finished product. While the Silicone molds are still warm, cover them loosely with a plastic sheet to keep the air out. Leave the items in their original packaging, but make sure it is completely sealed. Placing a hot pot of boiling water on the Silicone molds, though, is not recommended, as the Silicone may crack.

Before starting to pour the silicone molds and polymer mix, you should prepare the painting or glazing materials you will use. Paint mixing supplies such as acrylics and other pigments should be loaded into your paint mixing bags, and the mixing can start immediately. It's best to use a small paintbrush to mix the resins, so they will not pool on the sides of the molds. Once all the colors have been mixed well, place the molds and polymer mix inside and turn the knobs to get started. It's important to fill the molds with enough air so you don't have any air pockets in the final products.

The mixing process is pretty simple if you plan on making a small resin item such as a ball or star. You just have to change the liquid coat in the mixing bag one time, and then just follow the directions. For bigger objects, such as tree branches, arm ornaments, or figurines, the process gets a bit trickier. In order to get the right consistency, the professionals at Resin Art International use special hydrometers to measure the specific density or hardness of the resin. Once the proper hardness is established, the next step is to heat it up until it reaches the right consistency. Once the object has cooled down, it's ready for its first few coats of paint.
