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 glue gun sticks toxic?
Glue gun sticks are generally not considered toxic during normal use. However, when heated, glue gun adhesives may release fumes that can be irritating for some people, particularly those with respiratory sensitivities.
To help ensure safe use, work in a well-ventilated area and follow the instructions provided with the glue gun and adhesive sticks. As with many heated products, avoid using them near potential ignition sources.
Do you need specific glue sticks for a glue gun?
No, not all glue sticks are suitable for every glue gun. Bostik Handy Hot Melt Glue Gun, Bostik DIY Hot Melt Glue Gun and Bostik Craft Cool Melt Glue Gun are designed to be used with compatible glue sticks that match the requirements of each tool.
Using the correct glue stick size and type helps ensure smooth feeding, consistent adhesive flow and reliable performance. Before using a new glue stick, check that it is suitable for your glue gun model.
How should surfaces be prepared before using BL 50?
Before applying Bostik BL 50, clean and degrease the surface you want to treat. Once the surface is prepared, spray the product from a distance of approximately 20-30 cm and work it into the surface using a soft cloth.
Proper preparation helps Bostik BL 50 lubricate, protect and penetrate more effectively on metal parts and mechanical components.
Is Glue Gun glue waterproof?
Yes, Bostik Glue Gun Glue is highly water resistant and can provide a long-lasting bond in many DIY and repair applications. Once the adhesive has cooled and fully set, it can withstand moisture, temperature fluctuations and general wear.
To achieve the best performance, apply Bostik Glue Gun Glue to clean, dry surfaces and allow the adhesive to set fully before exposing the bond to demanding conditions.
Should you remove a Glue Stick from a glue gun?
No, it is generally recommended to leave a partially used Glue Stick inside the glue gun. Removing it may put unnecessary strain on the feeding mechanism and could affect how the tool operates.
If excess Glue Stick extends from the back of the gun, it can be trimmed carefully. Once the remaining Glue Stick becomes too short to feed properly, simply insert a new Glue Stick and continue using the glue gun as normal.
What is the difference between a hot melt glue gun and cool melt glue gun?
The main difference between hot melt and cool melt glue guns is the temperature at which the adhesive is applied.
Hot melt glue guns use higher temperatures and are commonly used for general DIY, repair and craft applications where a strong bond is required. Cool melt glue guns operate at a lower temperature, making them suitable for temperature-sensitive materials and applications where a lower application temperature is preferred.
Always use glue sticks that are designed for your specific glue gun to help achieve the best results
What is the lifespan of a glue gun?
The lifespan of a glue gun can vary depending on how often it is used, how it is stored and how well it is maintained.
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?
The operating temperature of a glue gun depends on the model.
Bostik Handy Hot Melt Glue Gun and Bostik DIY Hot Melt Glue Gun operate between 175°C and 200°C, while the Bostik Craft Cool Melt Glue Gun operates between 125°C and 135°C.
Using the correct glue gun and compatible glue sticks helps ensure reliable adhesive performance and safe operation.
What does viscosity mean?
Viscosity describes how easily a liquid flows. A low-viscosity adhesive is thinner and flows more easily, while a high-viscosity adhesive is thicker and is less likely to run or drip.
In adhesives and sealants, viscosity can affect application, spreadability and how the product performs on vertical or horizontal surfaces.
When should you use a Hot Melt Glue Gun instead of Super Glue?
Use the Bostik HG3 Hot Melt Glue Gun when you need to assemble, position or bond craft materials, decorative items or larger components using hot melt glue sticks. It is often a practical choice for hobby, craft and general DIY projects where a larger adhesive bead is required.
Choose Bostik Super Glue when you need a fast-curing cyanoacrylate adhesive for quick repairs and precision bonding. Bostik Super Glue bonds many non-porous materials in seconds, making it more suitable for small repairs where accuracy and speed are important.
