Hi Marc,

I’m afraid your resin isn’t going to cure in an environment like this. It needs to be in the low 70’s F for curing.

HI Eva,

I’m sorry to hear your resin isn’t curing. This article will help: https://resinobsession.com/resin-frequently-asked-questions/how-to-fix-sticky-resin/

If it is a polyester resin, then yes, curing with a tacky surface is normal. I talk more about that here: https://resinobsession.com/resin-resin-resin/polyester-casting-resin/

Hi Lior,

You are on the right track. You have already mentioned the two ways you can get this done:

1. The mold. If the mold you use is made from a template with sharp edges, then those sharp edges will transfer into your casting.
2. Sanding. You can sand your pieces post-curing to give them the sharp edges you want.

Hi Douglas,

What a great question! While I appreciate that you want to prolong the life of your resin as much as possible, I’m afraid that freezing isn’t a good idea. When the kit comes back to room temperature, condensation will form inside the bottles that can keep your resin from curing.

Hi Samantha,

It sounds like the resin layers are curing before she applies the next layer. Try applying the next layer of resin when the previous layer is like ‘jelly’, which is probably about 30 minutes or so after you mix the resin.

Hi David,

I’m sorry to say, but the surface exposed to air will remain tacky after curing. I talk more about it here:

Here are some tips that have worked for me:

For a tacky piece, I leave it out in the sun for a few minutes after curing with the lamp. If that doesn’t work, I leave it in a bright window the next day.

For the swirls, I believe it’s caused by uneven lighting. The resin shrinks slightly and pulls away from the sides of the mold. The side that hasn’t cured enough usually gets the marks. Make sure your piece is centered under your lamp and that all sides are getting light at the same time. I have a small mirror under my light for this reason too.

I hope that helps!

Hi Tia,

When you say quick-curing, how quick were you hoping for?

I just started using uv resin for small projects like keychains and earrings. I am using a 36w uv light and curing for 2-3 minutes like bottle says. When I take the pieces out of the mold they are hard but tacky to the touch that it leaves finger prints. It also sometimes leaves rough swirling edges on the long crystal type molds. Any suggestions on how to avoid this?

Hello!
I am trying to add my uncles cremains to a resin pendant for my grandmother as a keepsake. Did anyone figure this out and have pictures to show how I could go about this? I have worked with beach sand inside shells, as the example showed above. In my experience, I just kept adding sand to the shell through the curing process for the sand to show. If you want, email me and I will send you pictures of how that turned out. But for my Uncles Ashes, they seem to be a bit thinner and finer than the beach sand. So I don’t want to add to muh along with my 3d printed filament lettering that I am throwing into the first layer. Any adivce and help, I wold greatly appreciate it.
Thank you!

After one month curing i have faced same problem with my resined coasters using cup of cold water…
No problem with mugs cold and hot neither with hot cup of coffee…

A vacuum chamber is doing exactly what I would expect it to. It tends to bring the bubbles to the top (like beer) where they don’t always pop. Pressure casting is a better choice. Leave it under pressure the entire curing time.

[Katherine Swift]

Hmm. I wouldn’t expect them to cause the resin to cure soft. How long has the bangle been curing?

Unfortunately, the two reusable molds I know of (Composimold and Amazing Remelt) appear to filter UV light just a little too much.

I’ve experimented a lot with Amazing Remelt, and it can never quite cure the resin all the way. I even tried using completely clear UV resin on something about the size and thickness of a key, and it was still only half formed after an HOUR under the UV lamp. A nearly identical sized mold cured prefectly in 3 minutes in a clear plastic mold.

I haven’t tried Composimold, but I’ve heard it has similar problems of not being quite translucent enough.

If you HAVE to use it… it CAN be done. you just have to do paper thin layers of the UV resin, curing for 2-3 minutes each layer.
