How to use
Preparation
Fit the metal stand onto the front of the hot melt glue gun in the slots by the nozzle. Load a Bostik HG3 Hot Melt Glue Stick through the grip ring at the rear of the gun and press the trigger several times until the stick is positioned firmly in the gun.
Plug in the gun and a light will come on at the rear to indicate that it is in operation. Then, rest the gun on its stand and allow to warm up for approximately 5 minutes. Ensure surfaces to be bonded are clean and dry.
Application
Press the trigger until adhesive flows from the nozzle. To ensure a continuous flow of glue, insert further glue sticks into the rear of the gun and wait a few minutes until the stick has heated to the correct temperature. DO NOT FORCE THE TRIGGER.
Apply adhesive to one surface. Press surfaces together within 15 seconds. Use of a clamp or other holding device is not necessary.
Unplug the hot melt gun when finished and allow to cool before storing. Surplus glue stick may be trimmed off using a sharp knife. Do not pull glue sticks from the back of the gun as damage may occur.
How to remove
The adhesive can only be removed mechanically once cured by scraping carefully with a blade edge.
A residual thin film will remain, which can then be removed using a solvent cleaner.
Sensitive surfaces may be damaged by the hot adhesive or by the solvents used in the cleaning process. Always carry out a test before attempting removal.
FAQs
Are hot glue sticks safe to use?
Yes, Bostik Hot Glue Sticks are non-toxic and are suitable for a variety of craft, hobby and DIY projects.
While the glue sticks themselves are non-toxic, care should be taken when using them with a glue gun because melted adhesive and the glue gun nozzle can become hot during use. Always follow the product instructions and allow the adhesive to cool before handling bonded items.
Can I use any glue sticks with my glue gun?
No, not all glue sticks are compatible with every glue gun. The glue stick must match the size and specifications recommended for your glue gun to ensure reliable feeding and application.
Before using a new glue stick, check that it is suitable for your glue gun model. Using the correct glue stick size can help achieve consistent adhesive flow and optimal performance.
Should you leave a glue stick in a glue gun?
No, you do not normally need to remove a Bostik Hot Glue Stick from a glue gun after use. Glue sticks are designed to remain in the tool between applications and can be used again the next time the glue gun is heated.
To help prevent feeding issues, use the correct glue stick size and avoid forcing sticks through the mechanism. If a glue stick becomes jammed, allow the glue gun to cool before investigating the blockage.
How long can a glue gun last?
The lifespan of a glue gun depends on how often it is used, how well it is maintained and how it is stored.
To help extend the life of a Bostik Glue Gun, use the recommended glue sticks, follow the operating instructions and store the tool properly when not in use.
What is the operating temperature for a glue gun?
- Bostik HG3 Hot Melt Glue Gun operates between +175°C to +200°C.
How do you prepare surfaces before gluing?
Before gluing, make sure both surfaces are clean, dry and free from dust, grease, oil, rust and other contaminants.
Removing dirt, loose material and old adhesive residues helps improve adhesion and gives the best chance of achieving a strong, durable bond.
Why is viscosity important in adhesives?
Viscosity refers to how easily an adhesive flows. Products with a lower viscosity are thinner and spread more easily, while higher-viscosity products are thicker and offer greater control during application.
In adhesive applications, viscosity can influence how a product spreads, fills gaps and performs on vertical surfaces, making it an important factor when selecting the right adhesive for a project.
What is the shelf life of the adhesive I have bought and where can I store it?
The shelf life of adhesives varies from product to product, but typically ranges between one and two years from the date of manufacture when unopened and stored correctly in dry conditions - usually between +5°C and +25°C. Once opened, the life of the product will be more limited – this is dictated by variables including the type of adhesive, how it is stored, and how much adhesive is left unused. For more information, refer to the product’s Technical Data Sheet.
How do you remove hot melt glue from your fingers?
If Bostik Hot Melt Glue gets on your fingers, allow the adhesive to cool completely before attempting to remove it.
Once cooled, gently peel away the hardened adhesive without forcing it. If the adhesive does not come away easily or if irritation occurs, seek appropriate assistance rather than pulling the skin aggressively.
For a step-by-step guidance, see the How to remove glue from your fingers article, which explains how to safely deal with adhesive on skin and minimise discomfort during removal.
