It is designed for use in dry lining, plasterboard installation, and insulation systems, providing an effective acoustic barrier that minimizes sound transmission through joints, gaps, and voids. This formulation offers strong initial grab with excellent adhesion to plasterboard, timber, metal studding, and blockwork. Once cured, it remains flexible to accommodate low to medium movement without cracking or loss of adhesion. The sealant’s white finish allows for direct overpainting once fully cured, ensuring a clean, professional appearance.\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 strength and flexibility\u003c\/strong\u003e: Forms a durable, permanently elastic joint resistant to cracking or movement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual performance\u003c\/strong\u003e: Functions effectively as both a sealant and adhesive, simplifying on-site installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent adhesion\u003c\/strong\u003e: Bonds securely to plasterboard, wood, metal studding, and masonry without primer on most substrates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic performance\u003c\/strong\u003e: Provides a reliable sound barrier for walls, floors, and ceilings in partition systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMould resistant\u003c\/strong\u003e: Resists biological growth in humid or internal environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-flammable\u003c\/strong\u003e: Safe for use in a wide range of construction and finishing applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverpaintable surface\u003c\/strong\u003e: Accepts most conventional paints after full cure for seamless finishing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy cleanup\u003c\/strong\u003e: Can be cleaned from tools and surfaces with water before curing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize 900ml\u003c\/strong\u003e: Supplied in a large-volume cartridge suitable for high-coverage professional use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrylining and partitioning\u003c\/strong\u003e: Seals perimeter and abutment gaps in plasterboard systems to enhance acoustic insulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoard bonding\u003c\/strong\u003e: Fixes plasterboard to blockwork, studding, and other common substrates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation installation\u003c\/strong\u003e: Bonds kraft-lined and other insulation boards where acoustic and adhesive performance are required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCeiling and floor joints\u003c\/strong\u003e: Seals junctions between boards and other building elements to reduce sound transfer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral interior sealing\u003c\/strong\u003e: Suitable for most internal gaps where flexibility and adhesion are needed.\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 all surfaces are clean, dry, and free from dust, oil, or loose coatings.
