Reliable sealing with Soudal Butyrub

Practical benefits

Permanent plastic flexibility: The compound does not set fully in depth, accommodating low-movement joints up to 5% without cracking.
Weatherproof outer skin: It forms an elastic, watertight surface layer that shields your installations from moisture and UV degradation.
Paintable after 24 hours: You achieve a clean aesthetic finish by painting over the cured surface after 24 hours.

In a nutshell

The right choise for

With Soudal Butyrub, you achieve a reliable, permanently plastic seal for joints with limited movement up to 5%. This polybutylene sealant does not set fully beneath the surface, preventing cracking while absorbing minimal movement in masonry, window and door frames, sills, roofing, and caravan or bodywork construction. It quickly forms an elastic, watertight outer skin that effectively resists weathering and uv radiation. After 24 hours, you can paint over the joint with a sufficiently elastic coating to ensure a neat, durable finish.
