Faithfull FAIMGHD Heavy-Duty Mastic Gun 425ml

The Faithfull Heavy-Duty Mastic Gun is designed for professional and DIY sealing and adhesive tasks, offering robust construction and precise control. It accepts standard 425ml cartridges, making it compatible with a wide range of sealants and bonding products. A 285mm barrel length supports versatile application, while a high 10:1 thrust ratio and up to 2000Nm of max pressure deliver smooth, even flow with reduced hand strain. Ergonomic ribbed finger grips on a large handle, a 360° rotating barrel, a double spring ratchet, and a thumb pressure release provide precise feed and instant return, enabling accurate bead formation even in awkward angles or tight spaces. The gun includes a nozzle cleaning pin for maintenance and a built-in hook for hands-free storage when working at height or on the move. Built with a heavier gauge steel skeleton, it is designed for lasting performance and reliability, backed by a 5-year manufacturer guarantee.
