Hey everyone, it’s Mia here from the glitter glue crew, and this week I’ve gotten like, 17 DMs and 12 comments asking the same thing: “Can I use glitter glue on Styrofoam?” Glitter Glue
At first, I’ll admit, I was a little confused—you guys were hitting me with questions about Styrofoam (that’s the crumbly, light-as-air craft foam, right?) and glitter glue, like, left and right. We sell tons of our glitter glue for DIY projects, school crafts, holiday decor… but no one’s ever asked specifically about Styrofoam before. So I dug in, tested a bunch of stuff, talked to our lab guys, and even bugged a few craft shop regulars to get the real scoop. Spoiler: It’s not a straight “yes or no” answer. Let’s break it down.
First, let’s get the basics straight. What’s Styrofoam, anyway? Most people just call all lightweight foam “Styrofoam,” but the real deal is that white, rigid stuff used in packaging, coolers, and craft kits—usually made from expanded polystyrene (EPS). EPS is super porous, right? It’s full of tiny little air pockets, and it’s way softer than, say, a plastic cup or a piece of cardstock. That’s key, because what glitter glue is made of matters here too.
Our glitter glue, like most brands, is basically a mix of PVA glue (that’s the white craft glue base), water, and suspended glitter particles. Some of our specialty ones have a little extra pigment or a thicker formula for extra sparkle. But PVA glue is water-based, and here’s the thing: Styrofoam hates water.
I tested this last weekend. Took three different pieces of craft EPS foam, grabbed four different types of our glitter glue (regular silver, holographic blue, metallic gold, and our new “no-mess” kids glitter glue), and went to town. First, the regular silver glitter glue straight out the bottle. I squeezed a thick line on a corner of the foam, stepped back, and watched. Within 60 seconds, that spot started to bubble. The water in the glue was eating through the Styrofoam’s porous surface, melting that tiny EPS beads right into the glue. I tried wiping it off with a paper towel… and half the foam’s top layer came with it. Not ideal.
Then I tried the no-mess kids glitter glue, which has a little less water and a tiny bit more thickener to keep the glitter suspended. Same result, just a little slower. The melting was still there, just not as dramatic. The metallic gold one, which has a denser, more concentrated glitter load? Also melted, just a tiny bit less because the glue didn’t absorb as fast.
But wait—before you panic and ditch the idea entirely, there are workarounds. I found two that actually worked, and left the Styrofoam intact, no crumbles, no bubbles.
First trick: Prep the Styrofoam first. If you seal the surface, the water from the glitter glue can’t get in to melt it. I grabbed a can of clear acrylic sealer (the cheap craft kind, $3 at the dollar store) and sprayed a light, even coat on each piece of foam. Let it dry for 20 minutes, then went back in with the same silver glitter glue. This time? No bubbles, no melting. The glue dried clear, the glitter stuck exactly where I put it, and I didn’t have to worry about the foam turning into a soggy mess. I even tested it a week later—no peeling, no crumbling, the glitter still looked bright.
Second trick: Thin the glitter glue? Wait, no—thicken it. If you mix a little bit of cornstarch into our glitter glue, it cuts down on the water content, making the glue more like a paste instead of a liquid. I mixed one part cornstarch with three parts glitter glue, stirred it up, and tested it on un-sealed foam. Again, no melting, no crumbles. The paste was thick enough that it didn’t soak into the Styrofoam’s pores, and the glitter stayed suspended. I used this for a small Styrofoam pumpkin I was decorating for fall, and it turned out way better than I thought it would. It’s not for big projects, obviously, but for tiny, quick crafts? Total game changer.
Now, let’s talk about when you should NOT use glitter glue on Styrofoam. If you’re doing a large decor piece, like a big Styrofoam letter for a store window, sealing every inch with acrylic sealer might take too long. Or if you’re working with fragile, thin Styrofoam that can’t handle even a light spray of sealer? Then maybe our glitter glue isn’t the move. But for most small craft projects—like kids’ homework, holiday ornaments, mini centerpieces—you’re golden with the prep.
I also want to clear up a common myth here. Some people say “all glitter glue ruins Styrofoam, period.” No, that’s not true. The problem is the water content, not the glitter itself. The glitter is just stuck to the glue, so if you get rid of the water, you get the glitter on the foam without the melt. That’s why the prep works— it’s a barrier between the water in the glue and the Styrofoam.
A quick side note for anyone worried about mess: Our glitter glue is non-toxic, so it’s safe for kids to use, even if they make a small mess. But with Styrofoam, even if it melts a little, it’s not dangerous—just annoying, especially if you’re making something neat. The sealer trick is also kid-friendly, no harsh chemicals, just a spray that dries quick.
Now, let’s talk about why this matters for us, as glitter glue suppliers. We get tons of customers who are making holiday decor, school projects, and even event props with Styrofoam. A lot of them didn’t know about the water problem, so when their glitter glue ruined their foam, they thought the product was bad. That’s why I wanted to clear this up—no, our glitter glue isn’t defective, you just need to do a tiny prep step.
If you’re someone who’s planning a big project and needs a lot of glitter glue, our bulk packs are perfect for that. We’ve got 12-packs of all the popular colors, and we can even do custom blends if you need a specific glitter shade for a big order. I know a lot of small craft businesses use our products, and we’re here to help you figure out what works for your specific project—whether that’s Styrofoam, cardstock, wood, or even fabric.
Wait, I almost forgot another test: I tried our glitter glue on coated Styrofoam, like the kind that’s already got a thin plastic layer. No issues at all, even without sealer. That’s a good tip too—check your foam first. If it’s the kind that’s used for model making or has a glossy coating, you’re way less likely to have melting problems.
Let me wrap this up so it’s not too long. The short answer: Yes, you can use glitter glue on Styrofoam, but only if you prep the foam first. Seal it with a clear acrylic sealer, or thicken the glitter glue with a little cornstarch, and you’re good to go. No melting, no crumbles, just glittery fun.
