Self-Leveling Cement Underlayment for Vinyl Flooring | High Strength Floor Preparation Compound
K50 Self-Leveling Cement is a cement-based floor leveling compound designed for PVC vinyl flooring, LVT flooring, rubber flooring, and other resilient floor coverings. It is formulated with cement, graded aggregates, polymer dry powder resin, and imported additives to create a smooth, strong, stable substrate for professional installation. After mixing with water, it offers good flow and automatic leveling, forming a dense, high-strength base layer that helps prevent uneven surfaces, joint refle
Excellent self-levelling flow performance helps create a highly flat substrate.
Achieves laser-level surface accuracy with a deviation of ≤2 mm within a 2-meter straight edge.
Prevents visible joints, waves, and other surface imperfections after vinyl flooring installation.
Rapid strength development shortens construction timelines.
Enables foot traffic approximately 4 hours after application.
Supports faster subsequent flooring installation processes.
