Advantages

The high-quality silicone formulation allows for easy application and smoothing, enabling efficient work on joints. With 25% movement accommodation, the sealant is suitable for high-stress expansion joints and provides long-lasting jointing. Very good adhesion on smooth surfaces helps prevent moisture ingress into the substrate, while high wear resistance and long-term mold protection maintain the integrity of the sealed surface during cleaning and regular use.

Suitable for

• Sealing corner and connection joints in bathrooms and kitchens
