Sealing partitions and constructions of wood or metal.
Sealing ventilation ducts.
Joints in pedestrian areas.
Features a bubble-free curing and a movement capability of up to 25%.

Uses as a Multi-Purpose Adhesive

Window frames, thresholds, and stair treads.
Baseboards, skirting boards, and protective plates.
Prefabricated elements.

📦 Available Formats: Cartridge vs. Sausage

We offer the product in different formats to optimize your work and budget:

Format	Type of Packaging	Recommended Use	Key Advantages
Cartridge	Rigid plastic packaging.	Spot jobs, small sealings or applications that require more precise handling in hard-to-reach areas.	Convenient, clean, and easy to dispose of.
Sausage	Flexible wrapping (Foil Pack).	Filling joints and large volumes. It is the preferred format for intensive professional use.	More economical and ecological (less plastic waste) and allows for greater product capacity for filling tasks.

Both formats ensure the same Sikaflex quality and a very good adhesion to most construction materials.
