Pro Long-Barrel Spray Foam Applicator Gun – 1 m (39 in)

Pro Long-Barrel Spray Foam Applicator Gun

A professional-grade 1 metre (39 in) long-barrel foam gun built for the kind of sealing work radon mitigation, crawl-space, and air-sealing crews actually do. Reach deep into rim joists, slab edges, sump perimeters, and tight wall cavities without crawling into them.

Why we stock it

• Pro-grade performance at a working-man price. Comparable build and bead control to the high-end European brands that retail north of $600 — at a fraction of the cost.
• Long 1 m barrel reaches into rim joists, behind pipes, under decking, and along sub-slab membrane seams without acrobatics.
• All-metal body and threaded collar stand up to daily jobsite abuse and resist solvent cleaning between cans.
• Adjustable flow dial lets you lay a hairline bead for finish-grade sealing or open it up for cavity fill.
• Standard pro-can thread — fits any standard threaded gun-grade foam canister.

Built for radon & air-sealing work

• Sealing slab cracks, control joints, and floor-to-wall transitions before sub-slab depressurization.
• Air-sealing rim joists and top-plate penetrations where radon and conditioned air leak.
• Sealing the perimeter of sump-pit covers, pipe penetrations, and service entries.
• Tying off membrane seams and wall transitions in crawl-space encapsulations.
• General foam-and-fill on fence posts, framing gaps, and exterior penetrations.

Care & cleaning
