Description
This product is a gypsum-based material made from high-strength gypsum andfast-drying cement (as main cementitious materials), combined with sulfates, alka-line activators, and various construction chemical additives. It exhibits excellentfluidity in the fresh state,enabling precise leveling of indoor floors. It is especially suitable for underfloor heating backfilling, old floor renovation, and as a cushion base for various decorative surface materials.
Advantages
- Precise Leveling: Fluidity reaches 13.5~14.5mm; flatness deviation within 3m afterself-leveling is <3mm.
- Excellent Strength: 1-day compressive strength up to2200psi; 28-day strength up to 3600psi (high load-bearing capacity).
- Efficient Construction: 90-minute construction window; accessible for traffic in 12 hours (supports continuous construction).
- Micro-expansion & Crack Prevention: Volume change rate ± 0.03%, fundamentallyavoiding cracking risks.
- Eco-Friendly & Safe: VOC=0g/L; Class A1 fire resistance; main raw material is high-strength gypsum (green & low-carbon).
- Compatible with Underfloor Heating: Excellent thermal stability; avoids cracking from cold-heat cycles; has certain insulation performance.
Applications
Suitable for indoor dry environments, e.g.:
- Underfloor Heating Backfilling: Excellent thermal stability; compatible with cold-heat cycles of underfloor heating systems.
- Thick-Layer Leveling: Provides a solid,flat base for wood flooring, tiles, PVC flooring,etc.
- Old Floor Renovation: Repairs depressions/cracks in concrete substrates; enables rapid transformation.
Usage Method
Suitable for indoor dry environments, such as:
- The substrate must be solid, free of dust, hollowing, oil, or loose material; cracks need pre-repair.
- Apply a dedicated interface agent (1l-2 coats) to seal substrate pores and enhance adhesion; construction can start only after the agent is fully dry (3-4 hours).
Product Preparation and Construction
- Water-Material Ratio: Add water strictly per the recommended ratio (powder:water=30%-33%o); mix uniformly with a machine until slurry consistency isachieved.
- Construction Window: Mixed mortar must be used within 90 minutes.
- Pouring & Defoaming: Pour the slurry onto the substrate to self-level; use spiked shoes and a T-bar to remove air bubbles.
- Curing Requirements: Cure for 12 hours after construction; keep indoor ventila-tion (avoid direct strong wind).
Properties
- Appearance:Gray-white powder
- Recommended Thickness:10-100mm (one-time construction feasible)
- Dry Bulk Density:1800kg/m
- Access Time: 12 hours
- Subsequent Decoration Construction Time: 4 days
- Eco-Indicator: VOC=0g/L (meets green building requirements)
Packaging & Storage
- Packaging: 25kg/bag(moisture-proof packaging)
- Storage: Store in a cool, dry place; shelf life is 12 months.
Construction Area
- Approx.16.5kg of material is required per 1cm thickness per square meter (calcu-lated at dry bulk density of 1600kg/m2).
Notes: This product must be used srietly in ccordance with construetion specfications,and avoid using itin damp areas The specfic performance may vany slightly dlue to differences in substrate conditions and environment. It is recommended to conduct on-site tests before construction
