Practical benefits

Soudal prevents edge corrosion: You protect raw cut edges of aluminium profiles against moisture and oxidative wear.
Invisible and flexible seal: The crystal-clear synthetic rubber formulation cures flexibly to seal joints without harming painted surfaces.
Reliable weather and UV resistance: High resistance to water and outdoor exposure ensures your seams remain permanently sealed against the elements.

In a nutshell

The right choise for

With Soudal Aluseal 310 ml, you effectively protect cut edges and mitre joints of aluminium profiles against corrosion, moisture, and air infiltration. This elastic sealant based on synthetic rubber cures completely clear, providing an invisible, professional finish across your window and door assemblies without damaging lacquers or powder coatings. Thanks to its high resistance to weather and uv exposure, joints stay permanently sealed under harsh outdoor conditions. You can apply it smoothly and precisely with a standard manual or pneumatic caulking gun onto clean, dry, and grease-free surfaces. Once cured, this flexible sealant is easy to paint over with most common paint systems.
