SEAL 'N' FLEX® ONE PLUS P590
Bostik Seal 'N' Flex® One Plus P590 is a low modulus, universal polyurethane sealant, proudly made in Australia, and built on New Generation Flex-iQ technology for construction and expansion joints. Once cured, it forms a tough, bubble-free and flexible seal capable of handling cyclic movement of +100%/-50%, making it a strong fit for joints that expand and contract with daily and seasonal temperature change.
Suitable for interior and exterior use, it is designed for high-movement joints across concrete, cladding and masonry construction, giving builders and façade contractors a dependable, high-performance sealant for expansion and construction joints.
Why choose Seal 'N' Flex® One Plus P590?
Its low modulus formula absorbs significant joint movement, up to +100%/-50%, without losing adhesion or cracking, making it well suited to expansion joints subject to constant thermal cycling. It handles joint widths from 5mm up to a generous 80mm, making it a strong fit for large-format panel and façade work where other sealants fall short. It cures to a tough, bubble-free finish and remains paintable after a minimum of 7 days, giving a clean, consistent look on visible joints. It adheres without primer to standard concrete, mortar and bare aluminium, cutting prep time on straightforward substrates, while porous or non-porous problem substrates can be primed with Bostik N49 or N40 Primer for maximum performance.
It's made in Australia, and is available in 7 colours to suit a range of façades and finishes.
Where to use it
Seal 'N' Flex® One Plus P590 suits in-situ concrete and render, precast and tilt-up panels, aluminium composite materials, brickwork and blockwork, metal cladding, plasterboard, fibre cement sheet, aluminium windows, granite, sandstone and marble, and GRC, fibreglass and specialty panel systems. It's rated for joint widths up to 80mm, well beyond the standard range.
Aluminium composite and metal cladding substrates should undergo Pre-Tested Adhesion to Substrate (P.A.T.S.) testing before use.
TIP: Working on a general-purpose construction joint rather than a high-movement expansion joint? Reach for Bostik Seal 'N' Flex® Construction H361 - Construction H361 suits everyday sealing jobs, One Plus P590 is built for joints with significant cyclic movement and wide joint widths up to 80mm.
