VELOSIT SL 502 is a cementitious self leveling underlayment for concrete substrates. It creates a very smooth surface for coatings and floor coverings.
Typical applications:
- Interior and exterior use
- Suitable for permanently water immersed applications
- Leveling of concrete slabs and floors
- Cosmetic repair of surface defects on concrete floors
- Structural repair of concrete
- Application thickness from 1/8” (3 mm) to 2“ (50 mm). 5″ (13 cm) when extended with aggregate
- Self leveling screed
- Floor heating systems
Properties:
- Minimal shrinkage/expansion under dry or wet curing conditions minimizing the risk of micro-cracking
- Excellent flow with long pot life
- Smooth surface profile
- Fast air release with minimal requirement for agitation
- Ready for covering with ceramic tiles after 4 hours, for moisture sensitive floor coverings after 12 hours.
- 30 – 40 min. working time and 2340 psi (16 MPa) compressive strength after 4 hours
