How to use a hot glue gun: step-by-step guide

Glue guns are a handy tool for craft projects, hobbies, and quick household repairs. From DIY decorations to fixing broken items and tackling everyday projects, our step-by-step guide will help you use the Bostik Hot Melt Glue Gun.

Getting the best results from your hot glue gun starts with proper preparation and correct application. 

Step 1: Prepare your surfaces 

Before using your hot glue gun, make sure both surfaces are clean, dry, and free from dust, grease, or debris. For best adhesion, surfaces should be at room temperature, as cold materials can cause the hot melt adhesive to cool too quickly and reduce bond strength. 

Step 2: Apply the hot glue 

Press the trigger gently until glue begins flowing from the nozzle. Apply the adhesive to the surface that is typically harder to bond smooth materials such as metal, ceramics, and some plastics often require adhesive first, while rough or porous surfaces usually bond more easily. 

There’s no need to spread the glue manually. For foam materials, apply the adhesive in an “S” pattern to the surface rather than directly onto the foam. For fabric projects, use a smaller “S” pattern to improve hold. 

Step 3: Join materials quickly 

Once the adhesive has been applied, press the surfaces together as quickly as possible for the strongest bond. Hot melt glue begins cooling immediately, so working quickly helps deliver better adhesion. Apply firm pressure while the glue sets. 

Step 4: Reload your glue gun 

To maintain a continuous flow of adhesive, insert another glue stick into the back of the gun when needed. Allow a few minutes for the new stick to heat properly before continuing. Avoid forcing the trigger, as this may clog the gun.
