It combines the performance of a sealant and adhesive, forming a dense, resilient barrier that expands under fire exposure to maintain compartment integrity.\u003c\/p\u003e\u003cp\u003eWater-based and solvent-free, it is simple to apply, non-flammable, and easily cleaned with water. It achieves up to five hours of fire resistance when tested to EN1366-4:2006, offering a 25% performance increase over standard fire-rated sealants. Once cured, it remains flexible and resistant to cracking, ensuring long-term acoustic and thermal stability in joint and panel systems.\u003c\/p\u003e\u003cp\u003eWith a density of approximately 1.6 – 1.65 g\/cm³ and a Shore A hardness of around 40, this sealant provides a stable, smooth seal with low slump characteristics, even on vertical joints. It performs reliably between –15 °C and +70 °C and maintains its integrity across various building materials including plasterboard, timber, metal, and blockwork.\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;\"\u003e900ml\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 resistance\u003c\/strong\u003e: Provides up to 5 hours of fire-rated sealing performance when tested to EN1366-4:2006.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic barrier\u003c\/strong\u003e: Seals joints to minimize sound transmission between plasterboard walls, ceilings, and floors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-purpose formulation\u003c\/strong\u003e: Functions as both an intumescent sealant and a strong bonding adhesive for plasterboard and insulation panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePermanent flexibility\u003c\/strong\u003e: Retains elasticity to accommodate minor movement and prevent cracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-based and solvent-free\u003c\/strong\u003e: Safe, non-flammable, and easy to clean up with water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent adhesion\u003c\/strong\u003e: Bonds to plasterboard, timber, metal, and blockwork without the need for primers on most substrates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMold resistant\u003c\/strong\u003e: Maintains a clean, durable finish in long-term installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow slump performance\u003c\/strong\u003e: No slumping in vertical joints up to 20 mm × 10 mm at 25 °C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature range\u003c\/strong\u003e: Suitable for application between +5 °C and +40 °C; serviceable from –15 °C to +70 °C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge size\u003c\/strong\u003e: 900ml capacity for large-area sealing and bonding applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQs\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eQ: How long does the sealant last?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA: The sealant provides long-term stability and remains effective for years when applied correctly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is this product suitable for exterior use?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA: It is designed primarily for interior applications, but consult the technical guidelines for specific exterior use cases.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can it be painted over?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA: Yes, once fully cured, the sealant can be painted to match the surrounding decor.\u003c\/p\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516401828225,"sku":"MM_LB1348","price":17.24,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/570967766023b98a362068aa7c19bb55.png?v=1775833613","url":"https:\/\/londonbricks-uk.co.uk\/products\/intumescent-fire-acoustic-sealant-900ml-1","provider":"London Bricks UK","version":"1.0","type":"link"}
