*THIS PRODUCT HAS BEEN DISCONTINUED WE RECOMMEND USING THE IDEALSEAL AUTO-MARINE AS AN ALTERNATIVE* Siroflex Polysulphide Sealant is a one part polysulphide sealant designed to seal joints subject to movement where a tough, flexible, watertight seal is required. This sealant is easy to apply and has good adhesion to most building substrates. Has excellent durability and is paintable with alkydresin paints. Conforms to BS EN ISO 11.600 F20 HM
