Resin Molds Explained

You might wonder what the purpose of a silicone resin mold is, which we will explain here. We are all fond of random ornaments, but for many, Christmas is known for the little figurines and decorations that truly bring in the festive spirit. These little things that so many are dearly fond of, are made from resin, or resin plastic, and shaped with a resin mold, otherwise known as an epoxy mold. Molds are forms that can be placed in resin that are made out of two-part liquid polymers. Molds can come in all shapes and sizes, especially when it comes to resin art molds.

Best Resin Molds

You can choose from a variety of mold-putty when you make your own. Usually, silicone or latex rubber putties are used which can wrap around an existing object. Having captured the object’s shape with the putty, you can then remove it and fill it with the two-part epoxy resin mixture, which prepares a replica of the subject.

Molds and resin are used to make everything from toys to decorations to ornamental key chains, decorative covers for phones, and even tools and impact-resistant surfaces.


What to Look for When Buying Resin Molds

When purchasing the best silicone resin mold for the task you have in mind, there are a few variables to consider. There isn’t much to say about what the best resin mold is when there’s a variety of forms with different uses. It should be noted that you have the option of choosing between three types of resin molds, which are plastic molds that are already made, and do-it-yourself latex rubber and silicone rubber epoxy molds. We’ll analyze each of these molds to see which is best for your application so you can pick the one that’s right for you.

Resin Art Molds


Molds Purchased From a Store

Plastic is not necessarily used in all resin molds bought in a store, but it is most commonly used in beginner-level items. It would take quite a bit of time to cover all the shapes and sizes of these molds, so if you want to create some fun decorative pieces or a phone holder, visit the local craft store. You will end up with about 20 castings for about ten dollars.

It is not often necessary to coat these molds with something to prevent sticking before pouring casting resin into them because they are very smooth, durable, and promise smooth removal once the resin has been set.

Molds have only one disadvantage: they limit you to the forms that the manufacturer produces. Once you get bored with that design, it can be frustrating to have to work with a manufacturer’s design without considering having to buy another. Additionally, some molds are made from plastic that is not biodegradable or reusable, so they do contribute to the pollution of the planet, especially because they are mass-produced.


DIY Silicone Rubber Molds

Do-it-yourself resin molds or resin art molds allow for versatility and it takes away the possibility of boredom because you are able to create the mold that is perfect for your design, at any time. If you ever grow bored with the precast molds you purchased at the store, you can make your own molds for resin with silicone rubber, simply by creating a negative form of the object you wish to make the old off. You do this by adding layers on layers of silicone over the object and that makes the shape from the inside of the mold.

Silicone Resin Molds

You can remove the silicone coating as soon as it has become hard, and then fill this negative form with casting resin to recreate the object of your choice. You do not need expert skills for this product because it is simple enough for beginners. The application goes by pouring into a container that is soapy and then, wearing some rubber gloves, you must knead it until you feel it hardening. Once you are satisfied with the consistency, or per the instruction of the manufacturer, take the resin out of the water and then coat the object you wish to make the mold off with it.

The silicone resin molds must be allowed to set to the manufacturer’s recommendations before they can be used further. Furthermore, you can purchase silicone rubber molds in stores for a variety of niche designs, or order a custom design.

It is important to note that silicone putty molds can be used with foodstuffs, but silicone mold resin is not safe.


DIY Putty Molds of Latex Rubber

In the early days of silicone resin molds, latex molds were used more commonly, but they can still be found at most home improvement stores. Although it is more difficult to work with than the silicone rubber mold we discussed earlier, the experts will argue that it is more durable and requires less time. Create your Latex mold by coating an object, otherwise referred to as the master, with liquid latex and painting it. More than one coat is needed.

Silicone Molds for Resin

If you do not have a lot of time, we would suggest the silicone rubber mold material if your project is time-sensitive. Then, after the latex mold material has dried, you can add the non-sticking agent. Once the mold material has been covered, apply plaster of Paris and allow it to dry according to the manufacturer’s instructions. Removing the plaster from the replica object won’t require removing the mold itself once it has dried. Put the latex mold inside the negative you created with the paste, as soon as the plaster has been removed.

After pouring in your casting resin, you can begin replicating your chosen object.



Instructions for Using Your Resin Mold

Using silicone resin molds for the first time may seem like a heavy task at hand if you are completely unfamiliar with them. However, we’ve included a short, yet descriptive tutorial for you to follow if you get stuck.

Large Resin Molds


Mold Preparation

Wear tight-fitting gloves before you start working and make sure there is sufficient airflow. In order to create the mold and the resin, you need to take the following steps. The best way to start cleaning out mold is to use some soapy water and thoroughly wash the mold off. The silicone molds that are used for large castings tend to gather a lot of dust, which can affect the overall quality of the casting if not taken care of. Make sure that your workspace is cleared and clean, and lay down a protective covering over the surface.

It is always wise to prepare for the possibility of resin getting stuck, so it is better to be prepared. Feel free to spend a little extra on some anti-adhesive coating.


Resin Preparation

There are two parts to every resin product, or most of them anyway. These two parts are the hardener and the resin itself. Make sure that you meticulously follow the instructions provided on the availability of the product, by the manufacturer themselves. That way you will know how long to wait for the rein to set in the mold so that it can be extracted safely without ruining the shape that you are making.

Top Molds for Resin

You can always personalize the item that you are molding by adding bits of glitter, dye, or even flower petals to the resin so it can be seen through.  Stir thoroughly once everything has been placed in the mixing container until you are satisfied with the consistency of the design you create before moving on to the next step.


Pouring Resin Into Your Mold

While large silicone molds require more resin to mix on than small silicone molds, the resin can be poured straight into the silicone mold. The resin might have an odd consistency compared to most liquids, so you might need to use a small spoon to get it into the mold if the mold is smaller.

In order to lock up the mold, you must be sure no air bubbles remain in it after the mold has been filled.

As much as you might want to include decorative objects in the mold at this point, you will need to be prepared for the different effects that these decorative items will have on the resin, as the last thing you want is for the resin to leak from the mold at this point. For drying the resin, follow the instructions given by the manufacturer.


Removing Your Casting

You can save yourself hours of frustration and frustration-inducing frustration by removing the resin casting correctly from your workpiece. In order to avoid accidentally puncturing the casting, you should slowly remove it from the mold once you are sure the resin is dry.

Best Epoxy Molds

When you use an anti-adhesive spray on the mold beforehand, removing the larger objects from the mold should be much easier, while removing smaller objects should be much easier. If your casting has been removed, ensure that both your mixing cup and mold are thoroughly rinsed and cleaned before storing them.


With the knowledge of what resin molds are, how to create them, what type of resin molds are available (for any purpose), and how to create resin castings with silicone molds, you’re now ready to put your new skills to use.



Is Mold Release Spray Necessary for a hustle-free release?

Many resin artists often use mold release spray, but its necessity largely depends on the quality of the silicone mold you have. High-quality silicone molds typically don’t require the use of mold release spray.

While silicone molds generally release resin easily, some molds made from other materials may not. Proper care and handling can extend the lifespan of your epoxy molds.


How to Clean Your Silicone Mold

Cleaning a resin silicone mold is a straightforward process. Simply wipe it down gently with a damp paper towel. It’s essential to ensure the mold is completely dry before pouring resin or any other material into it.

After demolding a resin piece, remove any cured resin drips, wipe the mold clean, and store it in a cool, dark place.


What Can You Create with Silicone Molds and Resin?

Silicone molds offer versatility for resin art. You can craft various items, including epoxy resin jewelry, bookmarks, keychains, pendants, bracelets, geode resin art, hair accessories, resin tables, pyramids, paperweights, river tables, book or binder covers, resin coasters, and more. To maintain crystal-clear and bubble-free results, consider using a pressure pot for your resin projects. It can significantly improve the quality of your finished pieces.
