I ALWAYS get just the tiniest bit of dust or something on my resin, no matter what I do. It will be PERFECT, then while it dries, something falls into it. Even if I check it every hour for a couple of hours, then finally decide it looks good enough to leave alone til dried, it always ends up with some kind of debris on top! And I keep them covered!  I see resin items all the time that are perfectly beautiful, and it frustrates me that I have not turned out ONE perfect resin item! And I have made over 100 items!

Is there any way to remove a dust particle or air bubble in cured resin? I know the only thing that really "melts" resin is acetone, so would pouring a little acetone on the top and letting just the very top melt work? or is that going to leave a gloppy mess?  What about pouring another layer of resin over it? Would that hide the debris? Or will it just show right through?

THANKS! Smiley

What are you covering your resin WITH, and HOW? 

Some things will be made from materials that can shed little bits which can get onto the resin.

Are you covering the entire mold and resin, or just covering the resin areas?

When are you covering?...right away, or later?

What kind of area are you using for curing?...and area with lots of dust or lots of air circulation?

Try covering the mold with something larger than it is (width, length, height), like a Tupperware bottom or large cardboard box, or even a dome of aluminum foil.
Do that right away, and preferably in a room that isn't in a drafty or dusty place (and where the temp is in the right range for curing resin).

(To remove any dust or other particles, you'd need to sand down far enough to remove them, then polish the resin and/or coat it with clear polyurethane or a coat of epoxy resin. Sanding cured resin isn't easy though.  If you just added a coat of polyurethane or epoxy resin over your original resin-with-particles, they'd still show up.)

I cover the whole item. Usually with a plastic cup. Always something bigger than the item.

I always cover it right away. Then I check on it once or twice during curing to make sure nothing has landed on it.

I have several places I do my resin. I have a small office, but there is not much ventilation there and I am overpowered by fumes.  Usually it is my basment. A large airy space so that I don't suffocate. It is not dusty at all. Not that you can see with the naked eye anyway.

What would I use to sand down the resin? Sandpaper? Or is there something specific for resin sanding? I have no problem doing the extra work to sand it down. It is a lot better than starting all over! Most of my projects have paper as the base, so when I soak the resin off the pendant, I also lose my paper or photo.

I don't know why you're getting "bits" on your resin, but here are some other things to consider:

...basements are often damp, and humidity level does matter when curing resins

...your plastic cup may not be large enough to allow enough air to assist with the curing process, or it may keep the temp in a not-good range, etc

..."checking on it" even once or twice could allow bits to be swirled in under the covering

...your paper on the bottom of the resin may contain moisture which could cause bubbling in the resin, especially if it's not sealed... even if it's totally dry or sealed, why wouldn't you "embed" the paper in the resin rather than just pouring the resin on top of it...that would encase the paper fully, and it's even possible I guess that the exposed paper is losing bits that end up in the air??

...not sure why/how you're "soaking the resin off the pendant"...or what the "pendant" part is

...the type and brand of resin you're using could be making a difference

As I said, cured resin is difficult to sand down (you'd often need more than sandpaper for some sanding chores), and it's also difficult to do that in just one area so you can polish or coat it back to fully glossiness.  You can get info on doing it though here:

There is no problem with the actual curing. It cures nice and hard and clear.  I usually do not get a lot of air bubbles. I let the freshly mixed resin sit a few minutes before pouring it in, then what air bubbles I do have I just work to the top and get rid of. I just mentioned the air bubble in my original post just to cover any aspect of what would need to be removed from a cured resin item.

There is really no way to embed the paper. I seal the paper with white glue. Let it dry. Glue it to the bottom of a silver bezel cup pendant, let that dry. Then resin on top. There is no exposed paper. The resin spreads to the walls of the pendant.

When I mess up, I soak the whole thing in acetone to disolve the resin so I can reuse the pendant.

I use the rain drop resin and doming resin from Rio Grande. I've used casting craft and some other stuff from craft stores, but I am the most pleased with the rio grande stuff.

I think my solution is to just not keep checking on it. But I started doing that because when I first got started with resin it didn't even occur to me to check on them. Just pour the resin, cover, let dry for a day. So I was shocked when I discovered tiny fuzz on them when I know there was not a spec on them when I covered them. So now I do spot checks. And I pretty much always find specs. I use a fairly large plastic cup to cover. Sometimes I use a large plastic container if I want to cover everything together. What do most people use?

I just leave my resin items somewhere in the kitchen (on the table or stove) where I know they will not be disturbed for a long period of time.

I haven't ever covered my resin projects while they were drying, and I'm wondering if that may be an issue with your projects.  I would think that the item would need air circulation around it in order to dry well.

I don't remember the name of the resin I use, but it's the measure/pour/mix/use type.  Although, I have recently purchased Mod-Podge's 'Dimensional Magic' (eight bucks for a small bottle) and it works just like resin, but without all the setup and nonsense.

Perhaps you may want to try that?

Does 'Dimensional Magic' work like resin? Waterproof and all? I know some of the stuff sold for pendant making is not waterproof.

Weird that maybe covering my items is causing the specks. Maybe I will do a test without the covering. But usually I get a spec or two before I even get to the covering stage. Maybe I am in an environment that has a lot of particles that can not be seen with the eye, but show up if landing in resin.

I don't know if its waterproof or not and I purchased it awhile ago, so I don't have the packaging.

But as far as working like resin, I used it to make a bottle cap pendant for a swap and it came out perfect!

So i have never used resin before... i was wondering if they have to be used with molds? or if there's a way you can make your own mold??? These may be stupid questions, but i literally know NOTHING about the stuff!!

There are different kinds of resin, and the 2 main kinds are intended either for deep molds or for shallow molds and coatings.  And one "tweaked" epoxy resin (Easy Cast) can be used for both but has some disadvantages after curing.

You can read a lot about the kinds and how they can/should be used, as well as molds you can use or molds you can make to use with resin, plus much more, in my previous YahooAnswers here (which also include a link to the page at my site on resins):
