About this item

The Faithfull Heavy-Duty Metal Frame Mastic Gun is built for professionals and DIYers who demand maximum performance, comfort and precision in sealant application. Constructed from heavier gauge steel, this high-strength skeleton gun ensures long-lasting durability under demanding site conditions while still accepting both C20 and C30 adhesive and sealant cartridges up to 425ml, making it ideal for a wide range of jobs, from construction and glazing to bathroom sealing and general repairs. The 10:1 thrust ratio combined with 2000Nm max pressure delivers powerful, smooth and controlled dispensing, even with thick adhesives or sealants, reducing hand strain and providing professional-quality bead lines every time. The 360° rotating barrel allows flexible positioning, making it easier to work at awkward angles, corners or in tight spaces. Comfort is enhanced with ribbed finger grips on the larger handle, minimizing fatigue during repetitive use. A double-spring ratchet mechanism ensures positive, precise feed when the trigger is pulled and instant return on release. The built-in pressure release thumb lever provides instant pressure control and prevents unwanted drips for cleaner bead lines, ensuring ease of use and smooth results. Practical features like a ladder / belt hook centre rod for convenient storage and easy accessibility between uses and an integrated nozzle cleaning pin to keep nozzles clear of dried sealant or adhesive help you work faster, cleaner and more precisely.
