Roof & Gutter
Match the product to your substrate and job. The guide shows which Soudal silicone, hybrid polymer sealant or adhesive suits each application, and the surface prep that makes it last.
Roof & Gutter silicone is the exterior-grade silicone for direct UV and weather exposure. Used for downpipe joins, gutter join sealing, valley flashing, roof penetration sealing and exterior cladding gap sealing. The formulation is UV-stabilised so it doesn't degrade or yellow in direct sun over the silicone's service life.
Also known as: Roofing Silicone, Gutter Silicone, Downpipe Sealant, Flashing Silicone, Exterior Silicone.
Soudal Roof & Gutter silicone 290ml cartridges in Translucent / Clear (127779). Bremick Roof & Gutter silicone 310ml cartridges in Translucent / Clear. Plus grey, black and colour-matched variants in the wider range.
CHEMISTRY AND PROPERTIES
Acetic-cure silicone with UV stabilisers. Service temperature -40°C to 150°C. UV-stable over the silicone's design life (15-20 years typical in direct exposure). Not for use on marble, granite, copper or zinc.
APPLICATION AND CURE
Clean substrate, apply continuous bead at the join, tool within 10 minutes. For gutter joins, apply a generous bead and seat the joining piece firmly so the silicone squeezes out evenly - this is the watertight seal. Cure 24 hours before exposing to rain or running water.
FORMAT AND SIZE
Soudal 290ml cartridge or Bremick 310ml cartridge - the small difference in volume reflects the two manufacturers' standards. Both fit standard adhesive guns.
