Soudal Roof & Gutter Silicone in a 300 ml translucent cartridge is engineered for demanding exterior sealing, waterproofing and bonding tasks. Ideal for roofs, gutters, flashings and any area exposed to harsh weather, it forms a durable, flexible seal that resists UV, temperature extremes and water ingress. The silicone adheres strongly to aluminium (including powder‑coated and anodised), PVC, roof tiles, stainless steel, zinc and galvanized surfaces, making it a versatile choice for both professional contractors and DIY enthusiasts. For optimal results, clean non‑porous substrates with Soudal Cleaner & Degreaser before application.
