Sika Everbuild Everflex 115 GP Building Mastic Grey 285ml

Summary

Sika Everbuild Everflex(R) 115 GP Building Mastic is a traditional oil-based pointing compound designed for general sealing and pointing of joints in conventional construction. Suitable for both internal and external applications, it delivers a reliable weatherproof seal for tradespeople working on door and window surrounds, composite panels, and low-movement vertical joints. Applied quickly and cleanly from a standard cartridge gun, it is an established site staple.

Features

• Oil-based formulation provides an effective and durable weatherproof seal for a wide range of building joints.
• Overpaintable using conventional decorative paints, helping to blend repairs and increase long-term durability.
• Adheres to concrete, brick, wood, metals, and glass without the need for a primer.
• Semi-drying compound - forms a surface skin while remaining permanently plastic beneath, accommodating minor joint movement.
• High solids formulation delivers excellent gap-filling performance on irregular or uneven joint faces.
• Good external weathering properties, with UV exposure causing no change to mechanical performance (surface discolouration possible).
• No slump at 70degC when tested in an 18 x 10 mm vertical aluminium channel, confirming stability in warm conditions.
• Suitable for perimeter pointing internally and externally around doors and windows.
• Rapidly and simply applied by extrusion from a standard cartridge gun.
