LIGHT WEIGHT SCREED
VELOSIT SC 241 is a cementitious light weight screed mix. It is mixed on site creating a rapid hardening overlayment with significantly lower weight than regular screeds. It is ready to receive flooring systems within 24 hours.
Typical applications:
- Interior and exterior use
- Bonded screeds
- De-coupled screeds on insulation or membranes
- Restoration of structures with limited static loads
Properties:
- Minimal shrinkage/expansion under dry or wet curing conditions minimizing the risk of micro-cracking
- Excellent workability
- Fiber reinforced
- Ready for covering with ceramic tiles after 6 hours, for moisture sensitive floor coverings after 24 hours.
- 45 min. working time and 1450 psi (10 MPa) compressive strength after 6 hours
- Final strength of more than 5940 psi (41 MPa) after 28 days*
- Open to foot traffic after 4 hours
- Very good adhesion to properly prepared concrete
- Excellent water resistance, no strength loss under water
- High tensile strength allowing thin applications on de-coupled screed applications
