Frequently Asked Questions (FAQ)
What is a spray foam gun used for?
A spray foam gun dispenses polyurethane foam with controlled flow, ideal for insulation, sealing gaps, window and door applications, and precision gap-filling.
Are spray foam guns reusable?
Yes. Professional models with PTFE/Teflon coating, such as Stanley, Kraken Bond, Sprayman, and Akfix, are reusable when cleaned properly after each use.
How do I clean a spray foam gun?
Use a polyurethane foam cleaner immediately after application. Flush the cleaner through the gun until all uncured foam is removed.
Why choose a Teflon-coated spray foam gun?
Teflon coating prevents foam adhesion inside the barrel, reduces clogging, speeds up cleaning, and increases the lifespan of the tool.
Can I leave a foam can attached to the gun?
Many contractors do, but only if the can still contains pressure and has not hardened. For long-term storage, remove the can and clean the gun.
Are all spray foam guns compatible with standard PU cans?
Most professional guns work with standard screw-type polyurethane foam canisters. Check the product specs for brand-specific compatibility.
What’s the advantage of a long-barrel spray foam gun?
Extended 24" or 40" barrels allow users to reach behind cabinets, beams, crawl spaces, and other tight or deep areas that standard guns cannot access.
Why is my spray foam gun clogging and how can I fix it?
Clogging happens when uncured foam dries inside the barrel or nozzle. Clean after every use with foam cleaner and avoid leaving foam residue in the tip.
Can a spray foam gun improve foam usage efficiency?
Yes. Spray foam guns provide adjustable flow control, reducing waste, improving precision, and creating cleaner and more consistent insulation lines.
What’s the difference between a spray foam gun and straw-applied foam?
Spray foam guns offer better control, higher precision, adjustable flow, and less waste, while straw-applied foam is for occasional small jobs.
