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?
The fumes that glue guns can release are very rarely toxic but can sometimes be irritating for those who suffer from respiratory problems. Take care when using the glue guns as like most organic fumes, there is a possibility they could ignite depending on the environment they are used in.
Can I use any glue sticks with my glue gun?
No - using the wrong glue sticks could block and damage your Bostik glue gun. We have two variations of glue gun, HG3 Hot Melt Glue Gun and Mini Hot Melt Glue Gun and each of our glue guns have specific glue sticks that are available.
How can you remove a glue stick from a glue gun?
If you haven't used all of the glue stick that you inserted into the glue gun, do not try to remove it. Removing the glue stick could damage the internal components of the gun - regardless if the adhesive is runny or hard.
Simply leave the glue stick in the glue gun until you use it again. Surplus glue stick may be trimmed off using a sharp knife.
When the glue stick is almost gone, you can insert another stick and continue to use the glue gun as normal.
How long do glue guns last?
A glue gun’s lifespan can vary depending on its use. Sometimes, a glue gun can stop working due to a glue stick being jammed or stuck in the gun, causing a blockage in the nozzle. Ensure you are always using the right glue sticks for your glue gun to avoid this problem.
Is the glue from a glue gun waterproof?
Yes - adhesive from a glue gun is waterproof. It is extremely water resistant and can deal with varying temperatures, other solvents and even eroding, making it a long-lasting, ultra strong adhesive.
What is the difference between a hot melt glue gun and cool melt glue gun?
The Bostik HG3 Hot Melt Glue Gun and Mini Hot Melt Glue Gun operates at a high temperature and is great for providing an ultra strong, long-lasting bond for challenging materials such as polypropylene, plastics, ABS, acrylics and even metals.
Cool Melt Glue Guns operates at a lower temperature and is commonly used for bonding heat-sensitive materials such as styro-foam, ribbon and polystyrene, which a hot glue gun could melt. Plus, with being cooler, they can be safer to use, which is great for younger crafters or in school environments.
What is the operating temperature for a glue gun?
- Bostik HG3 Hot Melt Glue Gun operates between +175°C to +200°C.
- Bostik Mini Hot Melt Glue Gun operates between +175°C to +200°C.
