Custom JS Waterproof Coating Manufacturers

JS Waterproof Coating: Definition and Classification

In the field of modern architectural waterproofing, JS Waterproof Coating (Polymer Cement Waterproof Coating) is highly regarded for its excellent performance. Zhejiang Bolei Coatings Co., Ltd., as a professional paint manufacturer based in China, is committed to developing high-performance waterproofing solutions. Our JS Waterproof Coating is a two-component waterproofing material composed of synthetic high-molecular polymer emulsion (liquid component) mixed with special cement and various inorganic fillers (powder component).

Through the physical and chemical reactions between the liquid and powder components, this coating forms a waterproofing membrane on the substrate that possesses both the durability of inorganic materials and the high elasticity of organic materials. As a core product of Zhejiang Bolei Coatings Co., Ltd., it is widely applied in both industrial and construction sectors.

According to national standards and practical engineering requirements, JS Waterproof Coating is generally divided into three types. The physical performance parameters are compared as follows:

Main Components of JS Waterproof Coating

Liquid Component: Zhejiang Bolei Coatings Co., Ltd. utilizes high-quality polymer emulsions such as acrylate and ethylene-vinyl acetate, refined with specific additives.

Powder Component: Selected high-grade Portland cement, graded quartz powder, and special active additives ensure a complete hydration reaction.

By precisely controlling the liquid-to-powder ratio, our JS Waterproof Coating exhibits superior film-forming effects in various complex construction environments, thanks to the strict quality control system and advanced production facilities of Zhejiang Bolei Coatings Co., Ltd.

Performance Advantages of JS Waterproof Coating

As a core architectural coating product of Zhejiang Bolei Coatings Co., Ltd., JS Waterproof Coating perfectly combines the flexibility of organic materials with the durability of inorganic materials. Our R&D team leverages the deep expertise of Zhejiang Bolei Coatings Co., Ltd. in new material development to ensure the product demonstrates multi-dimensional advantages in practical projects.

Excellent Physical and Mechanical Properties

The waterproofing membrane formed by JS Waterproof Coating possesses exceptional tensile strength and elongation at break. This means that even when the building structure undergoes subtle deformation or develops tiny cracks, the membrane produced by Zhejiang Bolei Coatings Co., Ltd. remains intact, serving as a long-term barrier.

Unique Construction Capability on Damp Substrates

Traditional waterproofing materials usually require a dry substrate, but JS Waterproof Coating can be applied directly to damp (but without standing water) surfaces. This feature significantly shortens the construction period, especially during rainy seasons or in underground projects, demonstrating the ability of Zhejiang Bolei Coatings Co., Ltd. to provide efficient engineering solutions to global clients.

Strong Adhesion

Thanks to a stable raw material supply chain and advanced formulas, the JS Waterproof Coating from Zhejiang Bolei Coatings Co., Ltd. features excellent adhesion to concrete, cement mortar, and other substrates. It is not just a waterproof skin but a protective layer integrated with the structural layer, effectively preventing coating detachment.

Green and Environmental Safety

As a responsible professional paint manufacturer, Zhejiang Bolei Coatings Co., Ltd. ensures that its JS Waterproof Coating is water-based, non-toxic, harmless, and pollution-free. It contains no solvents, produces no odor during construction, and complies with international environmental standards, making it suitable for high-safety projects such as drinking water tanks.

Convenience and Cost-effectiveness

The coating can be applied by brushing, rolling, or scraping, making the operation simple. Zhejiang Bolei Coatings Co., Ltd. ensures that JS Waterproof Coating maintains high quality while providing a competitive cost advantage through large-scale production and advanced facilities.

Performance Comparison: JS Waterproof Coating vs. Traditional Materials

Construction Process of JS Waterproof Coating

To ensure that JS Waterproof Coating achieves the best effect, Zhejiang Bolei Coatings Co., Ltd. recommends strictly following standard construction specifications.

Substrate Preparation

The substrate must be solid, level, clean, and free of dust, oil, and standing water. Any honeycombs, pitted surfaces, or cracks should be repaired first using repair materials compatible with Zhejiang Bolei Coatings Co., Ltd. products.

Mixing

JS Waterproof Coating is a two-component material. During construction, the liquid should be poured into the mixing bucket first, then the powder added slowly while stirring at low speed. Strictly follow the specific ratio provided by Zhejiang Bolei Coatings Co., Ltd. for Type I, II, or III. Use an electric mixer for 3-5 minutes until a uniform slurry without lumps or particles is formed. Let it stand for 2-3 minutes to eliminate bubbles.

Reinforcement of Key Nodes

Before large-scale application, reinforce corners, pipe roots, and floor drains with an extra layer of coating and reinforcement fabric. This is a vital experience summarized by Zhejiang Bolei Coatings Co., Ltd. over years of engineering practice.

Multi-layer Application

JS Waterproof Coating should be applied in 2-3 layers. Apply the first layer evenly with a thickness of 0.5 mm - 0.8 mm. After the previous layer is dry to the touch (usually 2-4 hours), apply the next layer in a cross-directional manner.

Quality Inspection (Water Test)

After the membrane is completely cured (usually 48 hours), a 24-48 hour water storage test must be conducted to ensure no leakage.

Main Application Scenarios for JS Waterproof Coating

Zhejiang Bolei Coatings Co., Ltd. utilizes its professional advantages to ensure JS Waterproof Coating covers all waterproofing needs from underground to roofs.

Indoor Waterproofing

Due to its eco-friendly nature, it is ideal for kitchens, bathrooms, balconies, and floors. Its film-forming ability effectively seals pores to prevent water vapor penetration.

Underground Engineering

Basements and garages require high water resistance. The Type II JS Waterproof Coating produced by Zhejiang Bolei Coatings Co., Ltd. has high-strength characteristics and can withstand long-term immersion.

Roofs and External Walls

In exposed environments, this liquid-applied coating offers seamless coverage, eliminating the leakage risks associated with the joints of traditional membranes.

Water Facilities

Including water tanks, swimming pools, and landscape ponds. Zhejiang Bolei Coatings Co., Ltd. ensures that JS Waterproof Coating maintains stable properties under long-term water pressure.

Core Precautions During Construction

To ensure the efficiency of JS Waterproof Coating, Zhejiang Bolei Coatings Co., Ltd. summarizes the following precautions:

Environmental Control

Maintain temperature between 5 and 35 degrees C. Do not apply outdoors during rain, snow, or high winds.

Prohibition of Unauthorized Mixing

The ratios of products from Zhejiang Bolei Coatings Co., Ltd. are optimized through experiments. Workers must not add extra water to increase coverage, as this reduces the tensile strength of the JS Waterproof Coating.

Thickness Control

Do not exceed 0.8 mm per layer. Cross the direction of each layer to ensure a dense waterproofing network.

Mechanical Stirring

An electric mixer at 300 - 500 r/min must be used until the JS Waterproof Coating slurry appears smooth like paint.

FAQ

Q1: Can tiles be applied directly after JS Waterproof Coating?
A: Yes. JS Waterproof Coating has great affinity with tile adhesives. Zhejiang Bolei Coatings Co., Ltd. suggests creating a rough surface during the final coat to increase bonding.

Q2: Why does the coating crack?
A: Usually caused by applying too thick a layer at once, a substrate that is too dry, adding unauthorized water, or exposure to intense sun immediately after application.

Q3: What are the differences between Type I, II, and III?
A: The core difference lies in the liquid-to-powder ratio and flexibility. The types produced by Zhejiang Bolei Coatings Co., Ltd. compare as follows:

Q4: How to tell if the coating is fully cured?
A: Press with a finger; there should be no obvious mark. Usually, at 25 degrees C, JS Waterproof Coating requires 24 hours to dry and 48 hours for full curing.

Q5: How to store leftover material?
A: Liquid should be stored in a cool place above 5 degrees C; powder should be kept away from moisture. Mixed slurry must be used within 2 hours. Zhejiang Bolei Coatings Co., Ltd. reminds customers that cured slurry cannot be reused by adding water.
