Skeleton Guns for Sealant Cartridges – Heavy-Duty Caulking Guns for Professional Use
Skeleton guns are designed to deliver reliable, even flow of sealants, adhesives, and similar materials from single-use cartridges. Their open-frame body makes them lighter than barrel caulking guns, improving visibility of the cartridge and reducing hand strain during extended use. With trigger control and a spring-loaded release plate, users can stop and start application with minimal mess or wastage.
Different thrust ratios cater to various material viscosities - lower ratios are suited for standard silicone sealants, while high-ratio guns handle thicker, more resistant materials like construction adhesives. A rotating frame allows smooth application around corners or irregular joints, while features like dripless mechanisms or anti-drip release plates help ensure a clean finish every time.
Skeleton guns are commonly used in window fitting, sanitary sealing, skirting installation, glazing, and general construction. They are compatible with most standard 310ml cartridges and are available in both standard-duty and trade-quality options, depending on the intensity and frequency of use. Models with ergonomic grips, hardened trigger plates, or zinc-coated steel construction are available for added strength and comfort on site.
Whether you're sealing expansion joints or applying grab adhesives, these tools help control flow rate and minimise mess - making your work faster, neater, and more professional. They’re a staple in decorating kits, construction toolboxes, and maintenance departments for good reason: precision and performance with every squeeze.
Skeleton Gun FAQs
Can skeleton guns be used with all types of sealant?
They can be used with most standard 310ml cartridges, including silicone, acrylic, and polyurethane sealants. However, for thicker, high-viscosity materials such as grab adhesives or fire-rated sealants, a gun with a higher thrust ratio is recommended to reduce user effort and ensure smooth flow.
What does thrust ratio mean in a skeleton gun?
The thrust ratio measures the amount of pressure applied to the cartridge per squeeze of the trigger. A higher ratio (e.g. 18:1) provides more force, making it easier to dispense thicker materials. Lower ratios (e.g. 7:1 or 10:1) are generally used for lightweight sealants that flow easily.
How do I prevent sealant from continuing to flow after releasing the trigger?
Look for skeleton guns with a dripless mechanism or a manual release plate that instantly stops pressure on the cartridge when the trigger is released. This helps prevent excess product from oozing out and reduces cleanup time.
