Key features

Water-Resistant Formula: Stable in kitchens, bathrooms and balconies - resists softening and powdering under humid interior conditions.

Excellent Sanding: Dust-free, smooth sanding keeps the surface fine and ready for paint, improving worker efficiency and health.

Strong Adhesion: Bonds firmly to concrete, cement mortar and gypsum board, preventing hollowing and peeling under decorative layers.

Fine & Smooth Surface: Micron-grade fillers deliver a silky substrate that maximizes the final coating's flatness and gloss.

High Strength & Crack Resistance: Polymer-modified formula resists shrinkage cracking on interior walls and ceilings.

Smooth Application: Creamy, slip-resistant consistency spreads evenly with a trowel; friendly for pros and trained DIY users.

High Whiteness: Bright white reduces topcoat consumption and prevents colour show-through on light finishes.

Single Component, Just Add Water: Factory pre-blended for consistent quality; no on-site dosing errors.

Eco-Friendly: Mineral-based, low VOC, compliant with green building standards for healthy interior spaces

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:What is this wall putty used for?

This interior wall leveling and water-resistant putty is for preparing concrete, cement-plaster and gypsum-board substrates before latex paint or wallpaper. It delivers a smooth, strong, paint-ready surface on interior walls and ceilings.

Q:What makes this putty different from ordinary putty?

Most water-resistant putties are too hard to sand. This interior wall putty keeps good water resistance while remaining easy to sand - low-dust, smooth finish - which improves worker efficiency and the final coating result. It also bonds strongly and resists shrinkage cracking.

Q:Can this wall putty be used in bathrooms or kitchens?

Yes for the wall base in humid interior zones - this putty is water-resistant. However, for continuously wet areas (shower walls, floors), apply a dedicated waterproofing membrane such as LANGUAN G1/G11 first, then this putty as the leveling base.

Q:What are the key technical specs I should know?

Bond strength >= 0.40 MPa (standard) and >= 0.35 MPa after immersion; water resistance 96 h with no chalking or detachment; surface dry <= 4 h; suitable for manual sanding; flexible at 50 mm rod with no cracks; hazardous-substance limits meet or exceed national standards.

Q:What is the mixing ratio and how do I apply it?

Typical ratio is 25 kg powder to 9-10 L clean water (to be confirmed by final TDS). Pour water first, then add powder and mix 3-5 min at low speed; let stand 2-3 min and remix briefly. Apply as a 1-3 mm skim coat with a steel trowel; for deeper irregularities, apply in two passes. Never add water to set slurry.
