Does it need a primer?

Dense concrete usually receives K32 directly without primer; porous/dusty base should be lightly pre-wetted to SSD.

How is it different from K31?

K31 uses EPS beads (organic); K32 uses vitrified microsphere (inorganic, closed-cell >95%) -lighter (600 vs 1200-1300 kg/m3), lower thermal conductivity, cleaner A-class fire.

Key features

Ultra-Lightweight Floor Leveling: At just ~600 kg/m3 dry density, it reduces structural dead load by 50-60% compared to conventional self-leveling compounds, making it ideal for elevated slabs and ret

Integrated Thermal Insulation: Thermal conductivity as low as 0.08-0.14 W/(m*K) turns the leveling layer into an energy-saving insulation barrier for underfloor heating systems.

Sound-Proof Floor Base: Impact sound improvement of 15-20 dB solves airborne and impact noise issues in apartments, hotels, and multi-story commercial buildings.

60% Weight Reduction: A 30 mm thick layer weighs only ~18 kg/m2 versus ~45 kg/m2 for standard self-leveling, dramatically cutting transport and handling costs on site.

Rapid Work Progress: Pumpable application up to 50 m distance and 3-30 mm single-pass thickness saves 40%+ labor time on large-area projects.

Underfloor Heating Ready: The low thermal resistance maximizes heat-up speed and energy efficiency in residential and commercial radiant floor systems.

Heritage Building Retrofit: Ultra-low added load makes it safe for old buildings, lofts, and mezzanines where structural capacity is limited.

Crack-Free Lightweight Screed: The closed-cell vitrified microsphere structure eliminates the shrinkage cracks common in lightweight cement mortars, ensuring a stable base for resilient flooring.

True Inorganic Fire Safety: Unlike EPS foam concrete, the all-inorganic vitrified microsphere composition achieves non-combustible Class A rating with no toxic smoke risk.

All-in-One Thermal-Leveling: Replaces separate insulation board + screed + self-leveling into one pour, cutting material layers and total installed cost.

AI-Powered supplier vetting

SummaryShanghai Languan New Building Materials Co., Ltd. is described as a developer, manufacturer, and seller of environmentally friendly building decoration materials. Its stated scope covers building materials, floor-related solutions, machinery and equipment, hardware, chemical products, communication equipment, and import/export and technical services. The supplier reports OEM service for well-known brands, quality assurance, documented complaint-handling and corrective-action procedures, and facilities including mixing, self-leveling, and automatic packaging lines. However, it has no available SDK, no stated AI-based decision-management practice, no inventory capability, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial information is limited to years identified as 2021–2023 without performance values. Certification, customer cases, and detailed customization evidence are not sufficiently documented.

Supplier typeThe supplier is presented as Shanghai Languan New Building Materials Co., Ltd., focused on R&D, production, and sales of environmentally friendly building decoration materials. Its business scope includes building materials, insulation materials, sealing fillers, cement products, machinery, hardware, chemical products, and related sales and import/export activities, supporting classification as a building-material manufacturer and supplier.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaint handling, and describes providing technical guidance and comprehensive customer services. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.

R&D capabilityThe company describes R&D activity and the ability to develop new materials using existing technology, and its culture emphasizes innovation. However, it explicitly has no available SDK and has not established an AI model for big-data decision support; these limitations prevent a broad conclusion that its innovation capability exceeds requirements.

Production capacityThe supplier states that it conducts production and lists processing and manufacturing activities, with a mixing line, self-leveling production line, and automatic packaging robot. Quality assurance and documented corrective-action procedures are also reported, although there is no valid contract with affiliated subcontractors and no in-stock capability.

Customization capabilityThe supplier reports OEM services for well-known brands and says it provides solutions for difficult floors, technical guidance, and development of various new materials using existing technology. This directly supports some customization and OEM capability, although the slices do not specify product scope, minimum quantities, lead times, or engineering resources.
