Sika Everbuild 115 Grey General Purpose Building Mastic (285ml) is a versatile, oil-based sealant designed for effective weatherproofing and sealing tasks in traditional construction projects.

Ideal for both internal and external perimeter pointing around doors and windows, this building mastic adheres seamlessly to common materials such as concrete, brick, wood, metals, and glass without needing a primer. Its high solids formulation provides excellent gap-filling properties, making it perfect for sealing composite sectional panels and low movement vertical joints. The mastic's semi-drying nature allows it to remain permanently flexible beneath its surface skin, while its Overpaintable finish and resistance to external weathering ensure long-lasting durability and ease of integration into any construction project.
