It is commonly used for sealing gaps, filling cavities, insulating around window and door frames, and securing pipes or conduits — delivering far more control and precision than a standard straw applicator.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What materials is this expanding foam gun made from?\u003c\/h4\u003e\n\u003cp\u003eA: This spray gun is constructed from a combination of durable plastic and alloy components, giving it a robust yet lightweight build. It measures 310 mm (12.2 inches) in length, making it easy to manoeuvre in tight spaces while maintaining a solid, professional feel.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I clean and maintain this PU foam gun?\u003c\/h4\u003e\n\u003cp\u003eA: After each use, it is recommended to purge any remaining foam from the gun using a PU foam gun cleaner solvent. Attach the cleaner canister to the gun and dispense until the nozzle and barrel run clear. Regular cleaning after every use is the best way to keep the gun working smoothly and extend its service life.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this foam gun compatible with standard PU foam canisters?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, this professional foam spray gun is designed to be compatible with standard PU (polyurethane) expanding foam canisters available from most hardware and building supply stores, making it a convenient and versatile tool for a wide range of sealing and insulation tasks.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a PU expanding foam spray gun and what is it used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A PU expanding foam spray gun is a professional-grade applicator tool designed to dispense polyurethane (PU) expanding foam from pressurised canisters.
