Quick Summary: Using the wrong floral glue can ruin hours of work - sometimes right before a big event. AIFD designer Sharon McGukin walks through the main types of floral adhesives, when to use each, and how to apply them correctly. Below, I’ve also added the glues we actually use in the shop every day, with affiliate links so you can grab what you need on Amazon.
Why the Right Floral Glue Matters (A Cautionary Tale)
I learned this lesson the hard way.
While prepping centerpieces for a wedding reception, we glued plastic floral foam anchor pins onto plastic dishes using a standard hot-melt glue gun - thinking it would save time. We greened the containers, then stored everything in the walk-in cooler overnight.
The next morning, the bonds had failed. The cold temperature caused “cold-cracking,” and the floral foam had separated from the containers. We had to redo all of it.
We caught it in time, but just barely. One day later, and it would have been a disaster.
The lesson: floral glue is not one-size-fits-all. The right adhesive depends on the materials you’re bonding, the temperature the design will be exposed to, and how long it needs to hold.
Watch: Which Glue Should I Use?
AIFD designer Sharon McGukin covers the main types of floral adhesives and the correct application technique for each, including a clever time-saving tip for working with Oasis floral foam.
Whether you’re a professional florist or a first-time DIYer, this is well worth 10 minutes of your time.
The 3 Floral Glues We Use In the Shop
After years of trial and error - and a few costly mistakes - these are the only adhesives we trust.
1. Pan Melt Glue
- Measures 16oz
- Use for any creative or decorative venture you can think of
- High quality design
Best for: All types of floral foam - wet foam, dry foam, and styrofoam.
This is the glue we use most often in the shop. Rather than a glue pot, we melt it in an old electric fry pan, which makes it much easier to coat larger foam blocks evenly.
Pan melt glue holds floral foam securely inside a container without taping. It saves time and gives a cleaner look. Once the glue has cured (usually within a few minutes), we soak the entire container in water with a floral preservative. The bond holds through the soaking with no issues.
Key benefits:
- Works on wet and dry foam
- No taping needed
- Much faster than frog pins for large arrangements
- Holds reliably through refrigeration
2. Oasis Floral Adhesive (Cold Glue)
Best for: Corsages, boutonnieres, and everyday fresh designs.
This is our go-to for wearable flowers and designs that will spend time in the cooler. Oasis cold glue is safe to use directly on fresh flowers and greens, dries quickly, and critically, it handles refrigeration without cold-cracking.
It bonds well to ceramic, glass, plastic, and fabric, so it’s versatile beyond just corsage work.
Bonus Tip: To avoid wasting corsage glue, use a tube squeezer (the kind made for toothpaste) to get every last bit out of the tube. It’s one of those small shop habits that adds up to real savings over time.
Key benefits:
- Safe on fresh flowers and foliage
- Refrigerator-safe - no cold-cracking
- Fast-drying and waterproof
- Works on multiple surfaces
3. Dual Temp Glue Gun
Best for: Decorative accents, ribbon, dried materials, and situations where you can’t bring the project to a glue pan.
We still keep a couple of dual-temp glue guns in the shop, even though we rely on them less than we used to. The dual-temp setting matters: low temp for delicate materials, high temp for heavier bonds on non-refrigerated work.
Important: Do not use a standard hot-melt glue gun to bond floral foam that will go into a cooler. That’s exactly what caused the cold-cracking disaster mentioned above. Use pan melt glue or Oasis adhesive for anything that will be refrigerated.
Key benefits:
- Portable - bring it to the project
- Dual-temp setting protects delicate materials
- Great for ribbon, dried botanicals, and decorative elements
- Widely available and inexpensive

Pro Tips for Using Floral Glue
1. Always read the instructions first.
Different formulas have different cure times, surface compatibility, and temperature tolerances. What works on plastic may fail on glass or in the cold.
2. Test before committing.
Before gluing 30 centerpiece containers, test one and leave it in the cooler overnight. Catching a problem with one is a minor inconvenience; catching it with all of them is a crisis.
3. Use a tube squeezer on cold glue.
Corsage glue tubes get wasted quickly when you can’t squeeze out the last third. A simple tube roller salvages a surprising amount of product.
4. Let the pan glue cure fully before soaking the foam.
Rushing this step causes bond failure when the foam swells with water. Wait at least 3–5 minutes before soaking.
5. Stick to floral-formulated brands.
Hot glue and generic adhesives sold at craft stores are not tested for use with flowers and foam. The brands with a consistent track record are Oasis, Lomey, and Atlantic - find them all on Amazon or through wholesale florist suppliers.

FAQ: Floral Glue 101
What is the difference between pan melt glue and hot glue?
Pan melt glue is a specialized formula melted in a low-heat pan, designed specifically for floral foam. Standard hot glue guns use a higher temperature that can damage foam and are not formulated for refrigeration. Pan melt glue bonds more reliably to foam and holds up in cold storage.
Can I use regular hot glue on floral foam?
It’s not recommended. Regular hot glue can melt or compress foam, resulting in a weak bond, and it cold-cracks when refrigerated. Use pan melt glue or Oasis floral adhesive instead.
What glue is safe to use directly on fresh flowers?
Oasis Floral Adhesive (cold glue) is the standard choice. It’s non-damaging to petals and greens, dries fast, and is safe to use on corsages and boutonnieres that will be refrigerated.
How long does floral glue take to dry?
Oasis cold glue typically dries within 1–2 minutes. Pan melt glue cures in about 3–5 minutes. Always wait for a full cure before the next step - especially before soaking foam in water.
What is cold-cracking, and how do I avoid it?
Cold-cracking occurs when a glue bond fails due to low temperatures, typically in a walk-in cooler. Standard hot-melt glues are the most prone to it. Avoid it by using pan melt glue or Oasis floral adhesive for any project that will be refrigerated.
Can I use floral glue on silk or artificial flowers?
Yes, a low-temp glue gun works well for silk and artificial materials. Oasis cold glue can also be used, but hot glue is usually faster and more practical for non-refrigerated decorative work.
How do I store floral glue between uses?
Keep tubes of cold glue capped tightly and stored at room temperature. For pan-melt glue, let unused glue solidify in the pan, and reheat as needed. It re-melts cleanly.
Where can I buy floral glue outside of Amazon?
Wholesale florist suppliers carry the full Oasis, Lomey, and Atlantic lines. Craft stores sometimes carry corsage glue, but selection is limited, and brands vary in quality.

Final Thoughts
Floral glue is one of those supplies that’s easy to take for granted until something goes wrong. The right adhesive makes your designs hold up through refrigeration, handling, and the full length of an event. The wrong one can undo hours of careful work.
Stick to floral-formulated brands (Oasis, Lomey, Atlantic), match the glue to the application using the chart above, and always test before committing to a full batch. That’s the shortcut that actually saves you time.
