Soudal Butyrub Sealant 300ml | Grey

Soudal Butyrub is a professional-grade polybutene sealant developed for sealing static and low-movement joints in construction, roofing and maintenance applications.

Unlike conventional sealants, Butyrub forms a weatherproof, watertight skin while remaining semi-setting beneath the surface. This self-repairing characteristic helps maintain long-term performance and flexibility in demanding environments. It can also be painted after curing, making it suitable for visible construction joints and finishing work.

With excellent adhesion to many common construction materials and strong resistance to UV exposure, weathering and chemicals, Butyrub is widely used for sealing window frames, door frames, roof details, masonry joints, gutters and building penetrations.
