Casting Resin Vs Table Top Epoxy Resin
Clear casting resin and table top epoxy are both very popular for encasing and suspending memorabilia, furniture, and more. They are quite similar in most ways; however, it is important to know how to use these two products properly for different projects. If they are used incorrectly, you risk ruining the item you wanted to preserve forever!
Many people use clear resin, such as EasyCast, when trying to encase a product or piece of memorabilia. Clear resin is a type of polyester resin which is perfectly, crystal clear. Clear resin can be dyed to another color in order to have a slight hue, but it will remain see-through. Make sure to only use dye specifically made for polyester casting resin. Often times, people use resin to encase things like coins, dried flowers, marbles, glitter and sequins, or insects. Fabric, wood, and photographs can also be sealed with resin, but first use a resin glue or sealant before applying the resin to ensure the color will not be distorted or tinted.

Is Deep Pour Epoxy Resin the Same As Casting Resin?
Yes, casting resin is often referred to as "Deep Pour Resin" as it can be used for thicker pours (as the name implies). You want to avoid using a coating epoxy (i.e. table top epoxy) for deep pours, such as river tables or encapsulating objects, because it will take many applications to build up the thickness you will need. Deep Pour Resins are slower to cure, therefore, allowing for a thicker "deep" pour. Speaking of coating epoxies...
So What's the Difference Between Casting Resin and Table Top Epoxy?
Table top epoxy resin can also be used for similar types of projects, but it is meant for thin pours. It is preferred for pouring over flat surfaces such as table tops, bars, or other flat items. Many people use table top epoxy to encase bottle caps or pennies in their bar. You can also use epoxy for making memorable chairs. Try painting a wooden box or other furniture with acrylic paints, then pour table top epoxy to protect it and seal it forever! Users often enjoy adding colors or glitter to their epoxy in order to create even more beautiful displays.
Clear casting resin needs a catalyst in order to properly harden. When the two are combined, they generate heat which then causes the resin to slowly harden. It is important to know how much catalyst to use with your resin. Increasing or decreasing the amount of catalyst, temperature, and dye can affect how long it takes for the resin to cure. Be sure not to add too much of your catalyst, this can cause the resin to generate too much heat leading to a misshapen or cracked cast. If you don’t use enough catalyst, your product may turn out slightly sticky. The curing process can take up to 24 hours, so be careful with your casting until it has completely hardened.
If you are using a table top epoxy, choose it wisely. You want to make sure you grab a good epoxy that will not bubble up badly or end up cloudy. Double check the epoxy you are using is a self-leveling epoxy as well in order to avoid having to level it yourself and risk ruining the project. Be sure to always pick a UV resistant epoxy as well. This will ensure you don’t have to worry about it turning a yellowish color over time. One of our favorite table top epoxies is this one as it is super easy to use, crystal clear, and great for beginners.
When using either of these products, you can use a variety of products as your mold such as oven-safe glass, rubber, silicone, or ceramic materials. Then, it’s time to start your project! Be sure to read the instructions for your epoxy or resin carefully and gathering everything you need before you begin. It is always recommended to cover the area you are working on with wax paper or another protectant. Also keep a rag and rubbing alcohol handy for any accidental leaks. For measuring and mixing, use a wax free paper cup. Do not use a cup you cannot throw away, because it will be ruined after your project! Do not use a Styrofoam cup either as that will melt away right in your hands from the heat of the mixture.
If you are using table top epoxy, you can pour the mixture over the entire creation after it is fully prepared for epoxy. If you have made a bottle cap bar or something similar, be sure they are glued tightly to the surface. If they are not, they will float up and the project will have to be completely done over again. Epoxy also needs plenty of curing time so be sure to wait a full 72 hours before using your creation! Also note that table top epoxy usually can only be applied in thin layers, so be sure to check with the manufacturer for recommended thickness.
If you are using the clear casting resin, then you will pour one layer of resin and allow it to dry into a gel. Then, lay your cast piece face down into your resin mold. If it is a flower or another item that doesn’t lay flat, dip it into the second batch of catalyzed resin before laying it on the surface of your gelled resin. Then, pour your next layers of resin over top. Check your product after about an hour or two for hardness and tackiness. Do not attempt to pull your piece from the mold until it is completely hard and no longer tacky. If there are any fingerprints or other marks on your piece, spray it with a few coats of a resin surface spray.

Should I Use Epoxy or Resin For My Project?
So, as you can see there are many similarities between clear casting resin and table top epoxy. However, they are definitely better suited for different types of projects, so it may be a good idea to consider which product will be easier to use for whatever project you have in mind. Some resins, such as Art N Glow, claim to be good for both coating and casting. However, we feel its better suited for casting as it is a very thin pour.
Epoxy and resin can definitely be finicky or difficult to work with. Be sure to do your research and watch a few YouTube videos (such as the one above) before attempting a new project. If your creation will be made of something important or valuable to you, I would definitely try giving a similar, unimportant job an epoxy coating and perfecting your skills before trying it on a sentimental or expensive item.
Epoxy and resin can be a fantastic DIY project as long as they are given the time and attention necessary for your project to turn out shiny and beautiful!
