Key features

Walkable in 4 Hours: Fast strength development enables foot traffic within 4 hours, dramatically shortening project timelines for flooring installation.

Laser-Grade Flatness for PVC: 2m straightedge deviation under 2mm, eliminating all substrate unevenness that causes seam gaps in elastic flooring.

Engineered for Elastic Flooring: Specifically formulated for PVC, linoleum and rubber flooring underlayment, preventing bulges, warping and joint issues.

Low Shrinkage and Anti-Cracking: Scientific formula ensures excellent volume stability during curing, fundamentally eliminating cracking and blistering risks on site.

Single-Component, Just Add Water: No separate liquid component needed. Simplifies logistics, reduces mixing errors and speeds up on-site construction.

High Compressive Strength: 28-day strength exceeds 30 MPa, delivering a dense and durable surface that resists long-term loads and heavy traffic.

Superior Moisture Barrier: Dense microstructure blocks upward moisture migration from substrate, protecting elastic flooring from bulging, warping and mold.

Zero VOC and Eco-Friendly: Non-toxic, odorless and non-radioactive formulation meets green building standards for schools, hospitals and residential spaces.

Pump-Compatible for Large Areas: Compatible with mechanical pumping systems for high-efficiency application on large-scale commercial projects with minimal labor.

Cost-Effective Coverage: Approximately 1.5 kg per m2 per mm delivers excellent material efficiency and competitive project cost per unit area.

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.

Product Q&A

Q:Is K50 a single-component or two-component product?

K50 is a single-component cement-based self-leveling compound. You only need to add clean water and mix : no separate liquid component required. This simplifies on-site logistics, reduces mixing errors, and speeds up construction.

Q:Can K50 be used under all types of elastic flooring?

Yes. K50 is specifically engineered as an underlayment for PVC flooring, linoleum, rubber flooring, and other elastic floor coverings. It provides the laser-grade flat surface these materials require.

Q:What is the difference between K50 and K18?

K50 is a single-component product specifically designed for PVC and elastic flooring underlayment (1-8mm), featuring laser-grade flatness and superior moisture resistance. K18 is a two-component high-strength product suitable for general-purpose floor leveling with higher compressive strength. For PVC flooring projects, K50 is the recommended choice.

Q:What is the water-to-material ratio for K50?

The water-to-material ratio is approximately 0.25:1, meaning about 6.25L of clean tap water per 25kg bag. Accurate measurement is required. Never exceed the recommended water ratio or add water to already-mixed slurry.

Q:What is the recommended thickness for K50?

YRecommended single-layer thickness is 2-5mm, with an overall range of 1-8mm. The thinnest part should not be less than 2mm. For applications exceeding 8mm, apply in multiple layers. For thickness below 2mm, ensure proper substrate preparation and use a notched trowel for precise control.
