The supplier reports 3D design, ODM, OEM, and multiple customization services, as well as new-product activity during the past year. It has stated tile-adhesive production information, in-stock capability, peak-season fulfillment within 15 working days, and export experience of five years, with exports representing 71%–90% of total sales. However, certification ownership, quality assurance status, raw-material traceability, valid manufacturing-capacity contracts, and fire-drill status are not established. After-sales complaint handling has a procedure but lacks written records. The supplier reports no overseas warehouse, showroom, agent or branch, or offline trade-show participation, and its overseas-service country count is stated as zero.

Supplier typeThe supplier is explicitly described as a manufacturer specializing in dry-mixed mortar, ceramic tile adhesive, and cement products. Its stated business scope also includes technology development, new-material research and development, environmental consulting, and related product sales, indicating a manufacturing-led materials supplier with supporting technical activities.

R&D capabilityThe supplier reports new products during the past year, technology development and new-material research activities, 3D software design services, ODM capability, and OEM service for well-known brands. It lacks an available SDK, but the broader evidence explicitly supports active product and technology development.

Production capacityThe supplier identifies annual tile-adhesive production of 1,000,000 tons, reports in-stock capability, and states that peak-season orders can be fulfilled within 15 working days. It is also described as a manufacturer, although the status of a valid manufacturing-capacity contract remains unknown.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, 3D software design services, and ODM services. These multiple stated service modes provide direct evidence of broad customization capability.

Product Q&A

Q:What is the difference between thin-layer and thick-layer polymer waterproof mortar? Which one should I use?

The main differences are application thickness and suitable areas. Thin-layer (within five millimeters) is for wall waterproofing, kitchen and bathroom tile substrates, and exterior wall seepage prevention ready for direct tiling after application. Thick-layer (above five millimeters) is for basements, water tanks, tunnels, and concrete defect repair where thickness and strength are needed. Simply put: thin-layer for walls, thick-layer for floors, pools, and repair.

Q:After applying polymer waterproof mortar on kitchen and bathroom walls, can I tile directly? Or do I need to apply JS waterproofing first?

You can tile directly. Polymer waterproof mortar has high bonding strength and its surface roughness is suitable for tile adhesive. Apply C1 or C2 tile adhesive directly for tiling eliminating the separate JS waterproof coating step. However, note: the final coat should be compacted and smoothed but not polished, maintaining some roughness for stronger tile bonding.

Q:Can I use this mortar for basement wall seepage from inside (negative side)?

Yes. Polymer waterproof mortar is suitable for both positive and negative water pressure applications. It is especially suitable for negative-side leak repair stop water from inside without excavation. However, if seepage is severe, treat obvious leak points with plugging material first, then apply the overall waterproof mortar layer.

Q:How thick can I apply in one go? Does it need layered application?

Do not apply too thick in one go. For thin-layer waterproofing, single-layer thickness of two to four millimeters is recommended. Total thickness exceeding five millimeters must be applied in layers, with alternating troweling directions between layers, and the next layer applied before the previous one sets to ensure tight interlayer bonding. For thick-layer waterproofing (e.g., basements), typically three coats of two to four millimeters each, with the final coat compacted and smoothed. Applyi

Q:How long after application can I proceed to the next step (tiling, protective layer)?

Generally, the next step can proceed after one day, depending on weather and thickness. Under normal dry conditions at room temperature, the waterproof mortar basically hardens within one to two days. However, before formal tiling, it is recommended to cure for at least seven days to ensure full hydration and stable strength. During curing, avoid rain, direct sunlight, and frost.
