Best Glue Gun for Sealing Wax Beads (And Why a Craft Gun Ruins Them)
Using a glue gun for wax seals is faster than a spoon and a candle, and for anything over about twenty seals it is the only sensible method. But the gun matters, and a standard craft glue gun will actively ruin your wax.
Why a craft glue gun is the wrong tool
Craft glue guns run hot — typically 190°C or more — because hot-melt adhesive needs that temperature to flow. Sealing wax does not. Wax starts to scorch well below that, and scorched wax turns brown, smells burnt and loses its colour depth. Gold goes muddy, red goes brown, white goes cream.
Worse, hot wax left sitting in an over-hot nozzle degrades between seals, so the twentieth seal looks worse than the first.
What to look for
Low temperature, ideally adjustable
Look for a low-temperature gun, usually marketed around 110–130°C. Adjustable dual-temperature guns are better still — you can dial down further for pale colours, which scorch most visibly.
The right stick diameter
Sealing wax sticks come in two widths: 7mm and 11mm. Match your gun to your wax, not the other way round. Most sealing wax sold for guns is 7mm, so a mini gun is usually correct.
A dedicated gun
Do not alternate between glue and wax in the same gun. Residual adhesive contaminates the wax, and the mixture never sets cleanly. A second cheap gun costs less than the wax you will waste.
A drip guard and stand
Wax is runnier than glue and will drip. A gun that stands upright and has a nozzle guard saves your table.
How to use it properly
- Let it come fully to temperature — five minutes, not two. Half-melted wax gives a lumpy seal.
- Purge the first squeeze. The first bit out of the nozzle has been sitting and is always slightly darker.
- Dispense in one steady pull. Stopping and restarting creates visible layers in the seal.
- Wait five seconds before stamping. The most skipped step in wax sealing. Molten wax squeezes out into a thin halo.
- Cool the stamp between seals on a damp cloth, or it will start sticking.
- Unload the gun when you finish. Pull the remaining stick out while warm — wax left to solidify inside is a nuisance to clear.
Glue gun or traditional spoon and candle?
Use a gun for volume: wedding invitations, packaging, anything over twenty seals. Faster, more consistent, less mess.
Use a spoon and candle for small batches and when you want the softer, slightly irregular edge that a poured seal gives. It also lets you blend two wax colours in the spoon, which a gun cannot do.
Both are covered in our wax seal kits, and guns and spoons are stocked separately under glue guns and melting spoons.
If the seals are going in the post
Use a flexible wax blend regardless of method. Traditional shellac wax is brittle and cracks in sorting machinery. Full detail in how to add wax seals to wedding invitations.
Frequently asked questions
Can I use a normal glue gun for sealing wax?
Technically it works, but it runs too hot and scorches the wax, dulling the colour. Use a low-temperature gun.
What temperature should a wax seal glue gun be?
Around 110–130°C. Hot enough to flow, cool enough not to burn the pigment.
What size wax sticks fit a glue gun?
Most sealing wax sticks are 7mm and fit a mini gun. Check the diameter before buying either.
How many seals does one wax stick make?
Roughly eight to ten, depending on seal size.
How do I clean wax out of a glue gun?
You largely do not — which is why you keep a dedicated gun. Pull the remaining stick out while the gun is warm and run a scrap stick through to purge the nozzle.
