Overview
Self-leveling compounds are polymer-modified cement mixes designed to create perfectly flat surfaces through gravity-driven flow. They revolutionized floor preparation by replacing traditional screeding methods with faster, more precise applications. These materials typically contain Portland cement, fine aggregates, and proprietary additives that control viscosity, curing time, and bonding strength. Modern formulations may include gypsum or calcium sulfate for specific substrate compatibility.
Physical and Chemical Properties
The compound's fluidity (150-300 mm flow diameter) allows it to seek its own level within minutes of pouring, then gradually thickens through hydration reactions. Final cured density provides excellent load distribution for floor coverings. Key performance metrics include compressive strength (20-35 MPa), abrasion resistance, and dimensional stability (<0.1% shrinkage). Advanced formulations feature low-dust properties and extended working times (up to 45 minutes) for large-area applications.
Main Applications
Commercial applications dominate 70% of usage, particularly in retail spaces, warehouses, and office buildings requiring flawless flooring substrates. The compound bridges cracks (up to 5mm) in concrete and compensates for minor elevation differences (3-50mm). Industrial facilities use heavy-duty versions with fiber reinforcement for high-traffic areas. Specialty formulations exist for radiant heating systems (improved thermal conductivity) and moisture-sensitive floorings (vapor barrier properties).
Safety and Storage
Unmixed powder requires protection from humidity to prevent premature clumping—store pallets on wooden boards with plastic wrapping. Shelf life typically ranges 6-12 months in original packaging. During application, ensure adequate ventilation as cement dust may contain crystalline silica. Wash tools immediately after use before material hardens. Cured product is chemically inert and non-hazardous.
B2B Procurement Guide
Industrial buyers should specify: 1) Required thickness range, 2) Substrate type (concrete/wood/anhydrite), 3) Desired walk-on time (4-24 hours), and 4) Special requirements like rapid drying or low-alkali formulas. Bulk purchases (20+ metric tons) often qualify for 10-15% discounts. Consider regional suppliers to minimize transportation costs—this product ships best in moisture-proof bulk bags rather than individual 25kg sacks.
