Verified by manufacturer 3 months ago
A one part, high modulus, modified polymer sealant for floor joints, heavy trafficked areas and cladding. Prisons and secure units (supervised areas) forming anti-pick/anti-vandalism joints.
Application
Suitable for use in structural joints in heavy cladding, structural movement joints in floors, and floor joints in heavily trafficked areas. Prisons and secure units (supervised areas) forming anti-pick/anti-vandalism joints, or any area that could be subject to abuse and vandal attack.
Description
A one part, high modulus, modified polymer sealant which cures, on exposure to moisture vapour, to form a tough but elastic rubber.
Features and benefits:
- Not recommended for joints in lightweight cladding and swimming pools.
- Very good UV resistance.
- Anticipated service life in excess of 20 years.
