It accommodates joint expansion up to +100% and compression down to -50%, absorbing the thermal expansion and contraction common in precast concrete tilt-up panels, brickwork, metal cladding, and aluminium window frames. With an elongation at break exceeding 1000%, it stretches reliably over wide movement cycles without tearing or losing adhesion to the joint faces.\u003c\/p\u003e\n\n \u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e+100% \/ -50% joint movement:\u003c\/strong\u003e Absorbs high cyclic movement in external cladding joints, reducing the risk of adhesive failure under extreme thermal shifts.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e\u0026gt; 1000% elongation at break:\u003c\/strong\u003e High elasticity prevents the sealant from tearing internally when joints open to their maximum width.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e2.5-3mm per 24 hours cure rate:\u003c\/strong\u003e Standard moisture-curing window, reaching full cure in 7 days on porous substrates, and requiring more than 14 days for joints wider than 20mm.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e-30 to 80°C temperature resistance:\u003c\/strong\u003e Maintains its physical seal properties and elasticity in harsh external environments and high-exposure metal facades.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e2.8g\/L VOC:\u003c\/strong\u003e Low-emission formulation suitable for environmentally rated projects, conforming to Singapore Green Building Council standards.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhere to use it\u003c\/h3\u003e\n \u003cp\u003eThis sealant bonds to major construction substrates and panel systems, including:\u003c\/p\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eConcrete and masonry:\u003c\/strong\u003e Insitu concrete, render, precast and tilt-up panels, brickwork, block work, GRC, and natural stone such as granite, sandstone, and marble.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCladding and windows:\u003c\/strong\u003e Aluminium composite materials, metal cladding, fibre cement sheet, and aluminium windows.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePlasterboard:\u003c\/strong\u003e Plasterboard face and paper-lined recessed edges.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMetals and plastics:\u003c\/strong\u003e Aluminium, u-PVC, brass, copper, and stainless steel.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eApplication and priming rules\u003c\/h3\u003e\n \u003cp\u003eBostik Seal ‘N’ Flex One Plus P590 adheres to standard concrete, mortar, and bare aluminium without a primer.
