TRUBUILD SEALMASTER FLEXI is a premium single-component, elastomeric joint sealant based on MS-Polymer (Modified Silane Polymer) technology. After application, it reacts with atmospheric moisture and cures into a strong, flexible, weather-resistant seal designed to accommodate movement while maintaining long-term adhesion. It is developed for both interior and exterior sealing applications where durability, elasticity, and reliable bonding are essential.

This sealant is especially suitable for construction and finishing applications requiring gap filling, movement accommodation, expansion/control joint sealing, and bonding of different building materials including metals, glass, ceramics, and similar substrates. Unlike conventional rigid fillers, it remains flexible after curing and resists environmental exposure over time.
