Foam Spray Gun 2-Pack - Professional Expanding Foam Applicators

In this review the Luft professional expanding foam spray gun 2-pack is examined for tradespeople and serious DIYers who use canned foam regularly. The bottom line: these metal-bodied applicators deliver precise control and easy maintenance, making them a good fit for window and door sealing, gap filling, and general insulation tasks where repeatable, neat application matters. The review focuses on build quality, control features and cleaning, and highlights where the guns excel and where users may encounter limitations.

Key Features

• Teflon coated inside and out: The PTFE coating reduces residue build-up so the gun is easier to clean and requires less foam cleaner between uses.
• Copper nozzle and spring trigger: The copper nozzle and trigger deliver precise flow control so the user can reduce over-application and the common problem of messy drips.
• Lock valve for residual discharge: The lock valve allows the barrel to be closed and residual sealant to be fully discharged for tidier storage and less waste.
• Wide compatibility: Designed to fit most 20-24 oz screw-on foam cans, the gun handles standard canisters used in commercial and home insulation work.
• Ergonomic metal body: The heavy duty metal construction and shaped handle provide a comfortable, stable grip during extended use.
• Includes extenders: The kit ships with additional extenders to reach tight gaps and awkward angles for versatile application.

Who It's For

This two-pack is aimed at contractors, handymen and experienced DIY users who apply polyurethane foam regularly and need reliable, reusable guns that reduce waste and speed up work. The precise trigger control and Teflon coating make it a practical choice for tasks such as sealing windows and doors, filling cracks in walls, and insulating around pipes and vents.

Users who rarely use foam or need a guaranteed leak-free connector every single time may want to consider single-use applicators or check connectors before purchase, since some customers report leakage at the can connector under heavy use. Those seeking a lightweight plastic option should look elsewhere; these are built as heavy duty metal tools.

Pros & Cons

• Teflon coating makes cleaning simpler and reduces the amount of foam cleaner required.

Cons

• Some users report leakage at the can connector, so careful attachment and occasional tightening may be needed.
• Heavy duty metal construction makes the gun heavier than plastic alternatives, which may matter for very long jobs.
