Details

Sikaflex® 221 Black is a high-performance multi-purpose adhesive and sealant trusted throughout the caravan, motorhome, campervan, automotive, and marine industries. Designed to create strong, durable bonds while remaining permanently flexible, it is ideal for a wide range of installation, repair, and sealing applications.

Once cured, Sikaflex 221 forms a tough rubber-like seal with excellent adhesion to many common construction materials including metals, timber, painted surfaces, ceramics, and selected plastics. Its weather-resistant formulation makes it particularly suitable for external applications exposed to vibration, movement, and changing weather conditions.

Popular for fitting solar panels, rooflights, vents, rails, trims, and other vehicle accessories, Sikaflex 221 provides reliable long-term performance without becoming brittle. It can also be sanded and painted once cured, making it a versatile solution for both professional installers and DIY projects.
