- Ready-to-Use Product Features
- Features
- This is a flexible stiff / creamy polysulphide joint sealant.
- When fully cured, this product is a rubbery elastic sealant with a high mechanical load capacity, good resistance to water, sea water, salt solutions, benzenes, and mineral oils.
- It is root resistant, does not rot, and it has very good retraction properties.
- High mechanical load capacity
- Good chemical resistance
- Resistant against sea water
- Resistant to mineral oils and petroleum
- Suitable for horizontal joints
Applications & Uses
- Markets
- Applications
- Cleaning
Clean tools immediately after use with KÖSTER Universal Cleaner.
- Fields of Application
- This product can be used to permanently and elastically seal horizontal joints in below grade construction, cracks in basements, foundations of buildings, joints in sewage treatment plants, garages, tunnels, etc.
- It is also suited for application on horizontal joints.
- Substrate
- The flanks of the joints have to be clean, solid, and free of grease and dust.
- Substrates must be primed with KÖSTER FS-Primer 2C.
- Application
- Mix both components thoroughly using a slow speed mixer until a homogeneous consistency is reached, (at least 3 minutes).
- The joint is filled approx. 2 hours after priming by pouring or with a caulking gun and is smoothed with a trowel or spatula or straight edge.
- Observe the DIN 18540.
