Faster, Neater Airtight Taping with a Foil Applicator Gun
Airtight taping is only as good as its application — and applying tape by hand over long runs is slow and prone to creases, bubbles and lifted edges, every one of which becomes an air-leak path on the test.

The problem with hand-taping
Hand-applying airtight tape across board joints, frames and junctions is fiddly and inconsistent. Creases trap air, edges lift, and adhesion suffers — so the seal you thought you had quietly fails when the building is pressure-tested to Approved Document L.
The solution: a foil applicator gun
The Foil Applicator Gun dispenses and presses IM Fleece Airtight Tape in one smooth pass, giving faster, neater, better-bonded seals on joints and junctions. Consistent pressure means consistent adhesion — which means a more reliable air-test result.
How it helps on site
- One-pass dispensing keeps the tape straight and crease-free
- Even pressure improves adhesion to the substrate
- Faster over long board-joint and frame runs
- Less waste and rework
Benefits
- Faster taping over long runs
- Neater, crease-free application
- Better adhesion means a better air test
Frequently asked questions
Does it work with any tape? It’s designed for use with IM Fleece Airtight Tape.
Is it worth it for a small job? On big taping runs the time saved is significant; for occasional details, hand-application is fine.
