Hainan Zhongyu Aquatic Products 51,500㎡ Factory Waterproofing Renovation Case (Rust Converter + Waterproof Coating Perfect Solution)

In the 51,500㎡ factory renovation project of Hainan Zhongyu Aquatic Products, Nanjing KEZU successfully solved the roof rust and leakage problems that had long troubled customers with its innovative rust converter and high-elastic polyurethane waterproof coating. This project not only significantly improved the waterproof performance of the factory, but also saved customers 20% of the cost, becoming a benchmark case in the field of industrial waterproofing.

Customer pain point: the dual challenge of rust and leakage

The factory of Hainan Zhongyu Aquatic Products was built in the coastal area and was exposed to high humidity and high salt environment for a long time, resulting in severe rust on the color steel tile roof and leakage in many places. This not only affected the production environment of the factory, but also increased maintenance costs. The customer had tried a variety of traditional waterproofing solutions, but the results were not ideal, and an efficient and lasting solution was urgently needed.

KEZU solution: rust converter + waterproof coating

1. Rust converter: fast rust removal, long-term protection

Nanjing Kezu's rust converter can be directly sprayed on the rusted surface to convert rust into a dense black paint film as a solid base for the waterproof layer.

In the Hainan project, the construction team completed the rust treatment in just 3 days without manual polishing, which greatly shortened the construction period.

2. High-elastic polyurethane waterproof coating: elastic crack resistance, long-lasting waterproof

On the base surface treated with the rust converter, the construction team sprayed two layers of KEZU high-elastic polyurethane waterproof coating. The elongation of the coating is ≥300%, which can adapt to the thermal expansion and contraction of the color steel tile and effectively prevent cracking.

The environmentally friendly water-based formula of the coating is non-toxic and odorless, and the construction process does not cause any impact on the production of the factory.

Construction process and efficiency improvement

1.Surface treatment: Use a wire brush to clean the floating rust and dust to ensure that the base surface is clean.

2. Rust converter spraying: Spray the rust converter evenly and wait for 1 hour for the surface to dry.

3. Waterproof coating construction: spray two layers of high-elastic polyurethane waterproof coating, 24 hours apart.

4. Quality inspection: After the coating is completely cured, conduct a waterproof performance test to ensure no leakage.

The entire project took only 7 days, which shortened the construction period by 30% compared with the traditional solution, while reducing labor and material costs, saving customers 20% of the total cost.

Project effect comparison

Before the renovation: the roof was severely rusted, leaked in many places, the production environment was affected, and the annual maintenance cost was as high as 500,000 yuan.

After the renovation: the roof is brand new, without rust or leakage, and the service life is expected to be extended by more than 10 years, and the annual maintenance cost is reduced to 100,000 yuan.
