What thickness should be applied?

Recommended total thickness is 1.5-2.0 mm, applied in 2-3 thin coats. Each coat should be thin and uniform.

What primer should be used before G1?

For porous or weak substrates, LANGUAN-690 sealing primer or a suitable interface agent can improve adhesion and reduce suction. On dense concrete, proper cleaning and SSD pre-wetting are usually sufficient.

Key features

Single-Component, Just Add Water: G1 is a ready-to-use dry-mix mortar - simply add clean water and mix. No liquid-powder ratio to balance, reducing on-site error and labor cost.

>= 24 MPa Compressive Strength: the cured layer reaches >= 24 MPa compressive strength, providing rigid, load-bearing waterproof protection that integrates with the structural substrate.

>= 1.5 MPa Impermeability: passes impermeability at >= 1.5 MPa with zero leakage, able to withstand long-term hydrostatic pressure in tanks, pools, and basements.

>= 1.0 MPa Bond Strength: forms a strong monolithic bond with concrete and mortar substrates, with no hollowing or peeling under water pressure.

Positive-Side Integral Waterproofing: applied on the water-facing side, G1 penetrates and densifies the substrate into a seamless rigid waterproof body - ideal for stable, non-moving structures.

Durable Against Hydrostatic Pressure & Corrosion: resists long-term water pressure, weak acids/alkalis, and aging - far more durable than thin liquid coatings for buried and immersed structures.

Potable-Water Safe, Zero VOC: water-based, non-toxic, odorless, solvent-free and zero-added-VOC; certified as green building material, safe for drinking water tanks and indoor use.

Wide Application Range: basements, bathrooms, kitchens, swimming pools, water tanks, grain silos, subway structures, and below-grade walls where rigid waterproofing is required.

Simple Brush or Trowel Application: no spray machine or special tools needed - brush or trowel suits both large areas and complex details, lowering equipment 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.

Product Q&A

Q:What is the difference between G1 and G11?

G1 is a single-component rigid waterproof mortar with high compressive strength, designed for positive-side waterproofing of stable, non-moving substrates. G11 is a two-component highly flexible mortar with >= 120% elongation, designed for crack-prone substrates and negative-side (back-side) waterproofing.

Q:Does G1 require a liquid component?

No. G1 is a single-component dry-mix powder. Just add clean water and mix - no liquid-powder ratio to balance on site.

Q:What is the impermeability of G1?

G1 passes impermeability at >= 1.5 MPa with zero leakage, suitable for long-term water pressure in tanks, pools, and basements.

Q:Where can G1 be applied?

Basements, bathrooms, kitchens, swimming pools, water tanks, grain silos, subway structures, and below-grade walls where rigid, positive-side waterproofing is required.

Q:What is the application temperature?

Apply when ambient and substrate temperature is between 5C and 35C. Avoid rain, fog, or freezing conditions.
