Is Hot Glue Gun Effective On Glass?

Hot glue works remarkably on glass and gives a strong bond. Hot glue guns have the capacity to connect with glass instantaneously. It’s a low-cost and efficient approach for bonding glass and other materials. Glass is a difficult surface to bond, but a hot glue gun might come in handy. These tools are simple to use and very effective in immediately forming a strong, long-lasting adhesive bond.

The trick, of course, is to choose the appropriate glue gun for your needs and preferences. Temperature control and increased wattage may be useful for more experienced craftsmen with particular materials, but they aren’t necessary for a newbie. If you’re going to be doing a lot of precision work, go for a glue gun with a thinner glue stick for a slower flow.

Can You Use a Hot Glue Gun On Glass?

Yes, hot glue guns can be used on the surface of the glass. Standard hot glue can reach temperatures of roughly 380 degrees Fahrenheit, whereas low-temperature glue guns may reach temperatures of around 260 degrees Fahrenheit.

Glass is difficult to attach, however, we have discovered a hot melt glue stick that will readily bond the surface of the glass. This hot melt is often used in the manufacture of PE boxes and display units.

How To Use A Hot Glue Gun On Glass?

When used to connect glass to other glassware or substrates, hot glue guns work well. There are several formulas available to meet every purpose. Paying close attention to surface preparation and any manufacturer guidelines will assist to secure the finest possible results.

Clean the Glass 

  • To clean, wash the glass with soap, use a professional glass cleaner, or soak it in isopropyl alcohol.
  • Allow it to dry for a few minutes.
  • To reduce oil residue, avoid handling the artwork with your bare hands afterward.

Sand The surface of Glass

  • Use 120-200 grit sandpaper to roughen the surface of the glass so that glue may adhere to it.
    Steel wool or emery cloth will also help, but remember that it only needs to be rubbed briefly.

Using Hot Glue Gun On Glass

  • Apply adhesive to both sides of the glass where it will be joined.
  • Press them together to bind them and remove any air bubbles.
  • Push gently so that the adhesive does not seep out of the joint. If it happens, blot up any excess.
  • To keep them together, use a clamp, vise, masking tape, or rubber bands.
  • Many glass adhesives continue to “cure,” or form a stronger bond, for days or even weeks after they are applied.
  • Even if the connection appears solid, avoid adding force or heat to the bonded object for at least 24 hours following application.


  • To achieve a successful bonding, the glass bonding surfaces should be dry, clean, and free of grease, oil, or dust contamination.
    The temperature of the surrounding environment, as well as the materials used, can have an impact on the adhesive characteristics. At the proper temperature, the glue should be applied.
  • Too high a temperature slows the setting period, while too low temperature causes the adhesive to set before the materials are bonded.
    Applying too much or too little might have a bad effect on the bond.
    Inadequate amounts cause the glue to cool faster, resulting in poor bonding. Too much inhibits the bond from cooling down prior to compression completion, resulting in a weaker bond.

Things To Consider Before Buying Hot Glue Gun

Many crafts and even home repairs are considerably easier and faster to do using hot glue guns, giving professional-looking results with less effort. There are several hot glue guns on the market, which are excellent but may also cause confusion. It helps to think of hot glue guns as instruments that will assist you in achieving the desired outcomes for various tasks. Here are a few things to consider when purchasing a hot glue gun.

Size Of Gun

Hot glue guns are available in full and tiny sizes, with the size corresponding to the kind of glue stick that can be used. Narrow sticks are used in micro glue guns with a diameter of 0.27 inches, whereas wider sticks with a diameter of 0.44 inches are used in full-size glue guns.
Full-size guns release a bigger volume of hot glue with each press, but miniguns dispense a lesser amount, making them ideal for gift wrapping and kid-friendly projects.


Hot glue guns may be used at both low and high temperatures, and each offers its own set of advantages.

High Temperature: 

  • Heats glue around 380 degrees Fahrenheit.
  • It can melt multiple types of glue sticks, including acrylic ingredients that create a strong bond on glass, wood, and even metal.
  • More likely to burn or blister skin if touched while still hot. 
  • Ideal for bonding materials such as metal, rocks, wood, and glass together, 
  • Only adults should use them.

Low Temperature:

  • Low temperature guns heat glue to around 250 degrees Fahrenheit.
  • A low-temperature tool is less prone to produce unintentional burns than a high-temperature tool.
  • Only for use with low-temperature glue sticks, which feature a silicone base that quickly melts at reduced temperatures.
  • Suited for light-duty crafts such as paper chain crafting and scrapbooking
  • Tool for kid-friendly projects, although children must still be supervised while using any glue gun.

Dual Temp Glue Guns:

Most glue guns have a single temperature setting, however, a handful of them feature adjustable settings that allow for temperature change between high and low as needed. An adjustable-temperature gun may be the ideal choice for a wide range of craft and DIY tasks.

Pros & Cons Of Hot Glue Gun


  • Very strong bond for plastics
  • Accurate dispensing and measuring with the syringes
  • Resists water, impact, and most solvents
  • Can be drilled and sanded
  • Moldable and workable to cover cracks and holes
  • Leaves a surface that can be sanded or painted
  • No mixing and safe to use anywhere
  • Easy to use
  • Useful on a vast range of different materials
  • Very strong water-resistant bonds with a clear finish
  • Paintable


  • Takes a long time to bond and cure; can’t make quick fixes
  • Won’t adhere to all kinds of plastic
  • Harmful fumes during use, etc

Final Verdict

A hot glue gun is a crafter’s greatest buddy, but it’s also an underutilized tool for working with materials like wood, plastic, and glass. While glue guns come in a variety of sizes, from microscopic to industrial, they all have one thing in common: they work quickly. Hot melt adhesives bond in under a minute for a solid yet flexible grip, whereas other forms of glue adhesives may take minutes or hours to adequately cure.
