Why Choose Everflex 115 GP Building Mastic?
Unlike modern silicones, Everflex 115 is designed for traditional building applications, offering a semi-drying, flexible seal that moves with the structure while maintaining a weatherproof finish.
Its oil-based formulation and high solids content make it particularly effective for older buildings, external joints, and situations where a paintable finish is required.
