Everbuild Sikaflex Silicone (300ml, White) is a high-performance, one-component neutral-cure silicone sealant suitable for a wide range of internal and external sealing applications. Formulated for durability and flexibility, it maintains a strong, watertight seal even under movement and temperature variation — making it a reliable choice for both professional tradespeople and demanding DIY projects.

The neutral-cure formulation makes it safe for use on sensitive substrates including natural stone, marble, and mirrors, where acetoxy-cure silicones can cause staining or corrosion. Once cured, it is resistant to UV, weathering, and most common cleaning agents.
