- Features
- This is a polysulphide based elastic, pourable joint sealant in accordance with DIN 18540 for sealing joints in horizontal areas.
- 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.
- Application
- 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.
- 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.
