Sikadur 31+

Sikadur 31+ is a 2-component, low-VOC, thixotropic structural adhesive, moisture-insensitive, with high adhesion to most construction materials. It has high mechanical strength and can also be used for structural concrete repair, joint filling, and crack sealing. Sikadur®-31+ can additionally be used in do-it-yourself (DIY) applications by non-professionals, beyond professional use.

Suitable for structural concrete repair (Principle 3, Method 3.1 of EN 1504-9). Repair of spalling and damaged concrete in buildings, bridges, infrastructure and superstructure works. Suitable for structural strengthening (Principle 4, Method 4.3 of EN 1504-9). Bonding plate reinforcement. Suitable for structural strengthening (Principle 4, Method 4.4 of EN 1504-9). Adding mortar. The Product can be used for interior and exterior use.
