Sika Sikafloor CureHard-24 205L Concrete Surface Hardener
Sikafloor CureHard-24
Sikafloor CureHard-24 is a one part, clear sodium silicate based liquid to harden and provide an impregnating seal for fresh or hardened concrete.
Uses
- Horizontal old or new concrete surfaces, where a hard surface with light to moderate abrasion resistance is required e.g. warehouses, industrial plants, stores, shopping malls, parking structures, service stations, hangars
- As an impregnating sealer on concrete slabs where no specific curing efficiency or standards are required
- Suitable for interior or exterior applications as an impregnating sealer
- As a densifier in the process of grinding and polishing concrete
- Dust-proofing of prefabricated concrete elements
- Suitable for protection against ingress (Principle 1, method 1.2 of EN 1504-9)
- Suitable for physical resistance (Principle 5, method 5.2 of EN 1504-9)
Characteristics and Advantages
- Ready to use
- Easy to apply
- Improved chemical and abrasion resistance compared to untreated concrete
- Reduced dusting of concrete floors
- Very low VOC
- Non-yellowing
- Good penetration - designed to penetrate, not provide a surface seal
- Solvent free
- Colourless and odourless
