This highly flexible building silicone is ideal for sealing gaps that are prone to movement, such as expansion joints in concrete, movement joints in cladding, and around doors and windows. It offers excellent resistance to weather conditions, including UV light and rain, and is compatible with common building materials like aluminium, hardwood, and PVCu. The sealant adheres strongly to a variety of surfaces including painted wood, ceramic, glass, enamel, and many plastics. It dries quickly, forming a surface skin in nine minutes at +23°C/55% relative humidity. Key features include low modulus, waterproof neutral cure, bonding to most building surfaces, a cure rate of around 2mm per 24 hours, +/- 25% flexibility, and suitability for interior and exterior use without priming. It is designed to last up to 25 years.
