Once all epoxy is on the cup keep the cup spinning. Wait about 5-10 minutes and carefully (and with gloves still on) remove the tape from both the top and bottom. If you leave the tape on you’ll end up sealing it under the epoxy layer. Let the tumbler turner spin the cup slowly for 6-8 hours.
How long does an epoxy tumbler need to turn?
Once the entire surface has been evenly covered, allow it to turn until it is dry to the touch, within 18-24 hours. Once dry, remove the tape and allow it to finish curing. At 72 hours, it will have fully cured.
When can I stop spinning my tumbler?
Keep spinning until the resin left in your mixing cup seems set enough not to run. The Spin It is not designed to rotate more than 6 hours at a time, however. Once set up, you can stop the spinning but leave your epoxy tumbler on the machine. You will want it to continue to cure without touching the surface.
How long does epoxy have to turn?
Usually, it takes around 72 hours to fully cure the epoxy. Whatever the dry time, the resin should be allowed to fully cure before attempting to move or sand it. If the epoxy isn’t allowed to rest until fully cured, your project will be prone to surface contamination.
Does tacky epoxy ever cure?
You cannot leave the sticky resin, as it will not harden after time, it will remain sticky. You will have to either throw your item away or fix the problem. In order to avoid the problem all together make sure to do the following: You must measure out your resin and hardener precisely.
Do you have to sand between coats of epoxy on tumbler?
💡TIP: Remember: whenever your resin is dry, you need to sand before you apply a second coat to ensure the two layers bond together. If you don’t sand, you run the risk of the two layers eventually delaminating.
How many times do you epoxy a tumbler?
Our crafters wonder typically how many coats of epoxy is enough for their tumbler. It does depend on what you’re creating, but the average is 2-3 coats. To properly seal all the layers beneath, we recommend using a topcoat of your resin.
Why is my epoxy not sticking to my tumbler?
Mixing ratios can greatly affect how your piece will cure. If the mixing ratio is off or not completely mixed properly, this can cause the resin to remain tacky, or have soft spots. To ensure that you have the proper mixing ratios measured in measuring cups, and to ensure that you are mixing by volume.
Why is my epoxy separating on my tumbler?
This problem usually occurs in small spots, but it can happen to an entire piece too. It is caused by the resin and hardener not catalyzing properly, which means that the two parts were either not mixed thoroughly enough, or their mixing ratio was off. To avoid curing issues: Use fresh resin and hardener.
How do you know when epoxy is fully cured?
The epoxy resin and hardener mixture has cured to a solid state and you can dry sand it. You will no longer be able to dent it with your thumbnail. At this point, the epoxy has reached most of its ultimate strength, so it’s fine to remove any clamps.
How long should epoxy cure before sanding?
Tip: The epoxy resin must be really dry before sanding. You should therefore allow a waiting period of at least 48 hours before processing. Follow the manufacturer’s instructions, as there are resins that take even longer to harden completely.
Will epoxy set in cold weather?
Some resin/hardener combinations are formulated to cure in temperatures as low as 35°F. However, simply using a hardener that cures in colder temperatures does not guarantee dependable bonds. Epoxy can be used at cold temperatures but must be handled and applied with techniques adapted to cold temperatures.
Why isn’t my epoxy smooth?
The most common cause for uneven epoxy resin is often not using the correct mixing ratio, or even using hardener and resin that is too old. These problems can be prevented by ensuring your work area is well ventilated, not too humid, and using a torch to heat the epoxy and allow the air bubbles to escape.
How do you apply epoxy smoothly?
best results are achieved by applying the epoxy evenly. The ‘roll on and tip off’ method is a great way to do this – ‘roll on’ a thin layer of epoxy with a foam roller and then ‘tip off’ by dragging another roller, cut into sections, across it to leave the surface both level and free from air bubbles.
Why is my epoxy rubbery?
The main reasons your epoxy resin is flexible and soft boil down to not enough curing time, improper ratios of base resin and hardener, not mixing well, pouring too thin, expired or compromised resin, and moisture in your epoxy prior to cure- resulting in an epoxy resin that rubbery and flexible.
How do you fix tacky epoxy?
How to easily fix sticky Resin Recoat: Add another fresh layer of doming resin on top of the sticky spots. Move your artwork into a warmer spot for 24 and let it dry ( resin drying time 20-24 hours ). Sand the entiry sticky surface off with 80-grit sandpaper and pour another resin coat layer.
How do you remove tacky epoxy?
Scrape away any epoxy that is soft and sticky. Use a small paint scraper to remove most of it, and then use a small razor blade to cut off any small pieces that are left. Don’t push too hard with the paint scraper. Dents and scrapes in the bar top will be visible through the clear finish.
When can I apply a second coat of epoxy on a tumbler?

Is one coat of epoxy enough?
A durable floor will require at least two coats of epoxy, which must cure overnight between coats. “There is no such thing as a good one-coat job,” says Parker. Once the final coat is down, it’s best to wait at least three days before allowing a vehicle into the garage; full curing can take up to two weeks.
