When it comes to resin, you’ll need to let your resin sit for 12-24 hours before pouring. The resin will need to be stirred for at least 2-3 minutes before it is ready to be poured.
How do you know when resin is ready to pour?
You’ll know the resin is ready to pour when it has turned completely clear and all of the bubbles have popped. If you find yourself with a few small bubbles remaining, that’s okay! Just be sure they don’t interfere with pouring your glassware into the mold.
It can also help to let your resin sit for an extra day or two before pouring if you live in an extremely humid climate. Humid air causes some resins to set too quickly, so if this is happening to you and other DIYers in your area report similar experiences online, consider letting it sit longer before pouring.

How long should I let my resin sit?
The answer depends on a few factors. The most important thing to consider is the temperature of your room, as it can affect how quickly or slowly the resin will cure at room temperature.
For example, if you’re working in a cooler environment (below 70° F) and mixing up a large amount of resin, you may want to let it sit for several hours before pouring it into molds so that it has time to completely harden up.
On the other hand, if you live in an area where temperatures are warmer than 70° F and plan on working with a small amount of resin (like 1 ounce), then waiting just 15 minutes should be plenty!
In addition to taking temperature into account when deciding how long to let your mixture sit before pouring it into molds, remember that some resins have different curing times than others—you’ll need more time with thicker or less viscous resins such as CastinCraft Clear Cast Liquid Plastic Resin than with thinner ones like EnvisionTEC Satin Smooth-Cast Resin.
Also, keep in mind that there are many other factors besides these two things that determine how long it will take for any given batch of polyester-based epoxy putty material called “resin”: The consistency (thickness) of this substance varies widely depending on its manufacturer; therefore not only does curing time vary but also viscosity itself can vary greatly depending upon manufacturer preferences alone!
When can I take my resin out of the mold?
Once you have poured the resin and let it sit, the next step is to take your mold out of the container. If you are using a UV light, make sure to cure your resin for about 4 minutes, or until it is no longer tacky.

How long should resin sit After stirring?
- You should allow the resin to sit for at least a minute or two after stirring.
- If it is not mixed thoroughly, bubbles will form inside the resin and can cause issues during curing. This can result in small air bubbles trapped in your piece that are noticeable once cured.
- If you don’t stir properly after adding the hardener to your base resin, there may be an uneven mix of hardener and base resin. This could lead to slower than normal curing times for some areas of your piece!
How can you tell if resin is mixed?
You can tell that your resin is mixed when you see a uniform color; it should be clear, or at least translucent like water.
Small bubbles in the resin are also usually a good sign that it’s ready to pour. If your resin is still cloudy or has streaks, keep stirring until those are gone, and then try again!
What can I use to stir resin?
Now that you’ve got the resin ready, it’s time to start pouring. After you’ve poured your first layer, be sure to wait until it dries completely before adding another layer.
This can take anywhere from two hours up to 12 hours depending on how much resin you’re using and how thick each layer is.
During this waiting period, it’s best not to touch or disturb any part of your project—it’ll make things easier later if everything stays in place and looks clean when we finally pour our topcoat!
To keep yourself occupied while waiting for everything to dry out (and also so we don’t have an accident), why not get some more materials ready for your next steps?
How long does it take for epoxy to harden?
The curing time for epoxy is important in determining when you can pour the resin. The best way to find out how long it will take for your epoxide to cure is to read the instructions on the container. If you don’t have access to that information, there are some things you can do to estimate the amount of time it will take before pouring:
- Check your resin’s temperature and make sure it’s at room temperature. This will help speed up the curing process by allowing heat from within your body or a hot room to escape more quickly, thus cooling down faster as well.
- Use a mold that has been preheated with warm water; this also helps speed up curing times because the heat has already been introduced into both objects being joined together (mold + resin).
How do you know when epoxy is fully cured?
You can tell when epoxy is fully cured by looking for the following:
- Time. Epoxy will take roughly 24 hours to cure, depending on the temperature of your workspace and how many catalysts you added. If you’re not sure whether or not your epoxy has fully cured yet, check it after 24 hours.
- Color change. After 24 hours, if your epoxy turns from a clear liquid into something that looks like an amber or honey (depending on the type of resin), then it is ready to pour and use!
- Bubbles. As they say in cooking: “If something bubbles up while cooling, do that again before using.” Bubbles mean there was still some uncured resin in there—and if you pour this out onto your project and try to use it later down the line, chances are those bubbles will cause problems with adhesion or durability once they’ve been exposed to heat during curing again. So don’t just let bubbles sit around until they disappear; instead, make sure they’re completely gone before pouring!
Your resin is ready to pour when it has reached the appropriate temperature. This can take anywhere from 30 minutes to an hour, depending on how large your resin is and how much time you want to give it before pouring.
Once your resin has reached this state, use a stirring rod or other implements that won’t contaminate your resin with air bubbles to stir it well.
Pour the resin evenly into a mold and allow it to cure for several hours or overnight until it’s completely hardened.
Once you’re done with all of that, feel free to go back over any points that you think need more explanation or clarity!
