Glue Guns

About Glue Guns

Glue guns are indispensable bonding tools that use heat to melt solid adhesive sticks, delivering fast, reliable bonds across an impressive range of materials. Whether you're a professional tradesperson working on electronics assembly, upholstery, flooring installation, or shop fitting, or a DIY enthusiast tackling craft projects, woodworking, or household repairs, a quality glue gun provides significant advantages over traditional liquid adhesives. Hot melt adhesive sets in seconds rather than hours, creates strong bonds between dissimilar materials, and the glue sticks themselves have virtually unlimited shelf life when stored correctly.

The selection at Tooled-Up.com encompasses corded electric models that connect directly to 240v mains power for continuous operation at your workbench, cord-free designs that heat whilst plugged in then disconnect for brief cordless convenience, and fully cordless battery-powered versions offering maximum mobility on construction sites. With trusted brands including Steinel, Bosch, Dremel, Rapid, Arrow, and Sealey represented across 34 models, there's a glue gun suited to everything from delicate hobby work to demanding industrial applications. Most guns accommodate either 7mm diameter sticks for precision tasks or 11mm sticks for general-purpose and heavy-duty bonding.

Modern glue guns have evolved considerably beyond basic heating elements. Contemporary models feature dual-temperature control for working with heat-sensitive materials, precision nozzles for detailed applications, integrated stands for safe placement between uses, and ergonomic grips that reduce hand fatigue during extended sessions. Battery-powered options from manufacturers like Bosch increasingly utilise the same lithium-ion platforms as their cordless power tool ranges, making them particularly convenient if you already own compatible batteries from that system.

Jargon Buster

• Hot Melt Adhesive: A thermoplastic adhesive that melts in the glue gun's heating chamber and solidifies as it cools, creating a permanent bond. Sets within seconds to minutes depending on application thickness and ambient temperature.
• Glue Stick Diameter: The width of adhesive sticks used by the gun, typically either 7mm (for light-duty and precision work) or 11mm (for general-purpose and heavy-duty applications). Always verify compatibility before purchasing glue sticks.
• Operating Temperature: The heat at which adhesive is dispensed. Low-temperature guns operate around 130°C (suitable for delicate materials like foam, fabric, and polystyrene), whilst high-temperature models reach 195°C or higher for stronger bonds on wood, metal, ceramics, and plastics.
• Heat-Up Time: The period required for the heating element to reach operating temperature after switching on. Typically ranges from 3-7 minutes for mains-powered units, though rapid-heat models like certain Steinel designs can be ready in under two minutes.
• Cord-Free vs Cordless: Cord-free guns heat up whilst connected to 240v mains power, then can be disconnected for limited cordless use (typically 10-15 minutes) until the element cools. Cordless guns use rechargeable batteries and maintain temperature as long as the battery holds charge.
• Trigger Feed: The mechanical mechanism that advances the glue stick through the heating chamber. Professional models feature smooth-flow triggers for controlled, precise dispensing, whilst basic designs use simple push-through operation.

How to Choose the Right Glue Guns

Power Source: Corded electric models like the Bosch PKP 18E offer unlimited runtime and consistent temperature control, making them ideal for workshop environments and extended sessions. Cord-free designs provide brief cordless convenience whilst maintaining mains-powered reliability. For genuine site mobility and working in locations without power access, opt for cordless battery-powered options such as the Bosch ADVANCEDGLUE P4A 18V, particularly if you already own compatible batteries from the same manufacturer's range.

Temperature Control: Dual-temperature guns like the Arrow Dual Temp or Dremel Hobby 930 offer versatility for different materials. High-temperature settings (around 195°C) suit wood, metal, plastic, and ceramics, creating stronger bonds for structural applications. Low-temperature settings (approximately 130°C) prevent damage to heat-sensitive materials such as foam, polystyrene, ribbon, and delicate fabrics. Single-temperature guns are more economical but less flexible.

Glue Stick Size: The 7mm format suits precision work, detailed crafts, and light-duty applications with minimal adhesive waste. The 11mm size delivers greater coverage and faster application for general construction work, upholstery, and heavy-duty bonding. Consider how much glue you'll typically need per application and the size of surfaces you'll be bonding.

Heat-Up Speed: Professional tradespeople benefit from rapid-heat models that reach operating temperature in under three minutes, reducing downtime between jobs. Budget models may require five to seven minutes, which is acceptable for occasional DIY use but frustrating for time-sensitive commercial work.

Ergonomics and Features: Look for comfortable grip designs with trigger guards if you'll use the tool extensively. Integrated stands prevent hot nozzles from damaging work surfaces between applications. Drip-resistant nozzles reduce mess and waste. Pen-style designs like the Bosch GLUEPEN offer exceptional precision for detailed work, whilst full-size models provide better handling for larger projects.

Brand and Build Quality: Professional brands such as Steinel, Bosch, Dremel, Rapid, and Arrow typically offer superior reliability, consistent temperature control, and longer service life compared to budget alternatives. For tradespeople using glue guns daily, investing in proven brands available from Tooled-Up reduces downtime and replacement costs.

Safety Information

Burn Prevention: The nozzle and freshly dispensed adhesive can reach temperatures exceeding 195°C – sufficient to cause immediate serious skin burns on contact. Always assume the nozzle is hot during use and for at least 10 minutes after switching off. Never touch the metal nozzle or freshly applied glue. If hot adhesive contacts skin, cool immediately under cold running water for at least 10 minutes and seek medical attention for serious burns.

Electrical Safety: Corded models must be used with properly earthed 240v UK mains sockets. Inspect power leads regularly for damage, particularly where they enter the tool body. Never use damaged tools or leads. On construction sites, consider using a 110V transformer or battery-powered models to reduce electrical risk in accordance with HSE guidance for power tools in potentially hazardous environments.

Work Area: Always place hot glue guns on their integrated stands or heat-resistant surfaces – never lay them on their side where hot adhesive can pool or nozzles can contact flammable materials. Ensure adequate ventilation, as some glue formulations emit fumes during heating. Keep the work area clear of combustible materials, particularly when working with high-temperature settings.

Storage: Allow glue guns to cool completely before storage. Do not leave plugged in and unattended. Store glue sticks in a cool, dry location away from direct heat sources, which can cause them to soften, deform, or become unusable.

Eye Protection: Safety glasses are advisable when working overhead or in situations where hot adhesive could splash, particularly during upholstery work or ceiling installations.

Frequently Asked Questions

What's the difference between 7mm and 11mm glue sticks?
The measurement refers to the diameter of the glue stick. 7mm sticks suit compact glue guns designed for precision work, detailed crafts, and light-duty applications. They produce less adhesive per trigger pull, offering greater control but requiring more frequent stick changes. 11mm sticks fit standard-sized glue guns and deliver more adhesive per application, making them ideal for general construction, woodworking, flooring work, and heavy-duty bonding where coverage and speed matter. Always check your glue gun's specification – most accept only one size and using the wrong diameter will prevent proper feeding and may damage the mechanism.

How long does a glue gun take to heat up?
Heat-up time varies by model and power source. Mains-powered professional models typically reach operating temperature in 3-5 minutes, whilst budget versions may require 5-7 minutes. Rapid-heat designs from brands like Steinel can be ready in under 2 minutes. Cordless battery-powered glue guns generally heat more slowly, taking 4-8 minutes depending on battery charge level and ambient temperature. Always wait until the manufacturer's specified heat-up time has elapsed before attempting to dispense adhesive – using the gun before it's fully heated results in poor flow, incomplete melting, and weak bonds that may fail under stress.

Can I use any brand of glue stick in my glue gun?
Provided the diameter matches your gun (7mm or 11mm), different brands of glue sticks are generally interchangeable. However, the quality and formulation vary considerably between manufacturers. Premium sticks from established brands typically offer more consistent melting, stronger bonds, less stringing, and better gap-filling properties than budget alternatives. Some specialist applications benefit from specific formulations – for example, flexible glue sticks for fabric and leather, ultra-strong varieties for structural bonds, low-melt options for heat-sensitive materials like polystyrene, or coloured sticks for decorative applications. Always check compatibility information if using specialised formulations.

Are cordless glue guns as powerful as corded models?
Modern cordless glue guns using lithium-ion batteries, such as those in Bosch's 18V range, deliver comparable performance to corded equivalents in terms of temperature and bonding strength. The primary consideration is runtime rather than power – cordless models operate until the battery depletes, typically 30-60 minutes of continuous use depending on battery capacity and ambient temperature. For workshop-based applications with unlimited time and access to mains power, corded models remain more convenient and cost-effective. For site work, installations in occupied buildings, or locations without power access, cordless guns offer essential mobility. Cord-free designs (which heat whilst plugged in, then disconnect) provide a middle ground but only work cordlessly for 10-15 minutes before the element cools below operating temperature.

What materials can I bond with a glue gun?
Hot melt adhesive bonds effectively with wood, many plastics, textiles, leather, rubber, paper, cardboard, ceramics, and some metals. It excels at joining dissimilar materials that traditional adhesives struggle with, such as fabric to wood or plastic to metal. However, glue guns work poorly on certain surfaces: very smooth materials like glass or glossy plastics may not provide sufficient mechanical grip; highly flexible materials that undergo significant movement may break the rigid bond; and substrates like polyethylene, polypropylene, and silicone resist hot melt adhesive due to their chemical properties. For best results, surfaces should be clean, dry, and slightly rough. Test bond strength on scrap material before committing to critical applications, and remember that whilst hot melt creates quick, strong bonds suitable for most applications, specialist adhesives may outperform it for specific demanding structural or outdoor applications.
