Js Waterproof Coating

Our js waterproof coating is a polymer-cement waterproofing system developed for concrete, cement render, masonry and other mineral substrates. The system normally combines a polymer liquid component with a specially graded cementitious powder component. After mixing, it forms a workable slurry that can be applied by brush, roller or trowel. Once cured, the coating creates a continuous protective layer with good adhesion to the base surface. Compared with a completely rigid cement coating, a properly formulated js waterproof coating can accommodate limited fine cracking and minor substrate movement while maintaining close contact with the underlying structure. Two-component polymer-modified cementitious coatings are widely used for interior and exterior waterproofing and damp-proofing applications.

A reliable waterproofing project depends on details rather than coating the large flat area alone. Corners, pipe penetrations, floor drains, construction joints and wall-to-floor transitions are common risk points. Our js waterproof coating is designed to become part of a systematic application process that includes substrate repair, corner reinforcement, controlled coating thickness and adequate curing. The finished surface can receive compatible tile adhesive or other protective finishes after the required curing period. For distributors, the product provides a practical waterproofing solution for residential renovation, new construction and general commercial projects. For contractors, its cement-based character makes it familiar to apply while the polymer component improves adhesion, workability and continuity.

Repair waterproofing in renovation projects

Our company has focused on solving construction-related problems since 2003. Its research covers building materials, external-wall insulation structures, old-wall renovation systems, dry mortar and construction equipment. The company possesses more than 60 patented technologies and has been recognized as a National High-Tech Enterprise, a Zhejiang Provincial Technology-Based SME and a municipal R&D center.

The liquid and powder components of js waterproof coating must work together at the specified mixing ratio. Our quality-control focus therefore covers liquid-component stability, powder fineness, mixing uniformity, slurry workability and cured-film integrity. Production samples may be checked for appearance, consistency and application behavior. Substrate moisture, temperature and local construction conditions must also be considered before site application.

Our pre-sales service includes system explanation, product selection and application instructions. During construction, we support technical communication concerning substrate preparation, detail reinforcement and coating sequence. After delivery, we provide quality assurance and technical assistance for distributors and contractors. This service structure is based on the company's established pre-sales, in-sales and after-sales support system.
