Frame Sealant – Brown – Interior & Exterior Applications

Product Overview

This high-performance acrylic-based sealant is designed for durable, flexible sealing around external and internal window and door frames. It cures to a long-lasting, permanently flexible joint that accommodates building movement and can be overpainted once fully set. The brown color provides a neat, complementary finish on timber, metal, or darker frame materials, blending cleanly with surrounding surfaces. Suitable for both decorative and protective sealing, it adheres well to common construction materials including wood, PVCu, brickwork, stone, and concrete. The 290ml capacity offers efficient coverage for detailed frame and façade sealing work.
