Get the job done right first time with a dependable, multi-purpose silicone sealant built for everyday sealing applications. The Evo-Stik All Purpose Flex Silicone Sealant White C20 delivers a durable, flexible and waterproof seal that stands up to moisture, movement and changing weather conditions.
Designed for both interior and exterior use, this versatile sealant is ideal for sealing around baths, showers, sinks, kitchen worktops, door frames and window installations. Its advanced formulation ensures strong adhesion to a wide range of non-porous surfaces including glass, ceramics, plastics and metal, giving you a clean, professional finish every time.
Thanks to its permanently flexible properties, it easily accommodates movement between surfaces without cracking or shrinking—perfect for areas exposed to temperature changes or structural movement. The built-in fungicide protection helps prevent mould and mildew growth, making it especially effective in high-moisture environments like bathrooms and kitchens.
Whether you're sealing joints, preventing draughts or completing finishing touches, this silicone offers long-lasting performance you can trust.
Each cartridge provides approximately 10–11 metres of coverage (based on a standard bead size), making it a cost-effective choice for both small jobs and larger projects.
