Case Study
VELOSIT® SC 241
Light Weight Screed
Product Description
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.
VELOSIT SC 241 is a shrinkage compensated ready for use screed formulation with very quick strength development.
VELOSIT SC 241 is the result of many years in the field testing and research. VELOSIT SC 241 is ready to receive flooring systems within 24 hours.
