The foam expands up to 50 times its original volume, filling irregular or wide cavities that conventional fillers cannot reach. It adheres excellently to building materials such as brick, concrete, plaster, metal, and timber. Its formulation allows cutting, sawing, or plastering just one hour after application, enhancing efficiency on job sites. The 750ml size provides optimal yield, expanding to approximately 40 litres when fully cured. The gun-grade format ensures precise control, reduced waste, and cleaner application.\u003c\/p\u003e\u003cdiv style=\"margin-top:30px;\"\u003e\n\u003ch2 style=\"font-size:22px;font-weight:700;color:#1a1a2e;margin-bottom:16px;\"\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #e0e0e0;border-radius:4px;overflow:hidden;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#1a1a2e;\"\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003e750ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSales Unit\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Fire Rating\u003c\/strong\u003e: Classified to DIN 4102 Part 1, achieving Class B1 performance for up to four hours when properly installed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Gap Filling\u003c\/strong\u003e: Expands up to 50 times its can volume for complete coverage in irregular voids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Curing\u003c\/strong\u003e: Cures rapidly, allowing trimming or plastering within one hour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong Adhesion\u003c\/strong\u003e: Bonds securely to most construction materials including masonry, metal, and timber.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Insulation\u003c\/strong\u003e: Provides sound dampening in addition to thermal and fire-resistant properties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGun-Grade Application\u003c\/strong\u003e: Offers greater accuracy and control compared to hand-held versions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize – 750ml Can\u003c\/strong\u003e: Expands to approximately 40 litres, providing extensive coverage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor and Window Installation\u003c\/strong\u003e: Creates a fire-rated seal around frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Penetrations\u003c\/strong\u003e: Fills gaps around pipes, conduits, and cable entries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Gaps and Cavities\u003c\/strong\u003e: Seals irregular joints in concrete, stone, brick, and plaster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal and Acoustic Insulation\u003c\/strong\u003e: Reduces heat loss and noise transmission.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Guidance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Preparation\u003c\/strong\u003e: Ensure surfaces are clean, sound, and lightly moistened.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Method\u003c\/strong\u003e: Attach to a foam applicator gun for best results.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eQ: How long does it take to cure?\u003c\/strong\u003e\u003cbr\u003eA: The foam cures rapidly, within one hour, allowing for immediate further processing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can it be used on metal surfaces?\u003c\/strong\u003e\u003cbr\u003eA: Yes, it bonds securely to metal, as well as other common construction materials.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is it suitable for acoustic insulation?\u003c\/strong\u003e\u003cbr\u003eA: Yes, its closed-cell structure provides effective sound dampening.\u003c\/p\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516401566081,"sku":"MM_LB1336","price":32.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/72c1afe317798e97c24dcac9f21c2f8e.png?v=1775833604","url":"https:\/\/londonbricks-uk.co.uk\/products\/fire-rated-expanding-foam-gun-grade-750ml","provider":"London Bricks UK","version":"1.0","type":"link"}
