China is often called a construction powerhouse, and this real construction video shows exactly how sewage pool anti-corrosion is done on the ground in China.

Step 1:Substrate Preparation

Use high-pressure water jets to remove dust, oil, and debris

Grind or sandblast the concrete surface to enhance adhesion

Ensure complete drying; surface humidity must meet coating requirements Note: Surface preparation is the foundation of the entire system. Poor treatment will ruin everything that follows.

Step 2:Apply Concrete Sealer

Use a dedicated concrete sealer to block capillaries and prevent moisture rise

Apply evenly with rollers, 1-2 coats, avoiding missed spots or accumulation Proceed to the next step only after full penetration and drying

Step 3:Apply Mengneng Graphene Glass Flake Primer (Airless Spray)

Use Mengneng graphene glass flake primer with excellent impermeability and shielding performance

Applied via airless spray for uniform atomization, strong adhesion, and high efficiency

One-pass spraying forms a dry film thickness of 300–500μm

Allow 24 hours for natural curing to ensure a compact, pinhole-free film

Note: This primer layer provides adhesion, acid-alkali resistance, abrasion resistance, and impermeability—core to sewage pool protection.

Step 4:Quality Inspection

Check coating thickness, pinholes, adhesion, etc.

Record hidden works with images or reports

Final delivery must pass on-site acceptance and re-inspection

Every step—from base treatment to inspection—must be done thoroughly, with no shortcuts.

Proper coating ensures over 10 years of stable operation; neglect leads to repairs in just 1 year, with massive losses.

So—fast, solid, and impressive, right?

This workflow is based on years of project experience and applies to most municipal and industrial sewage pools.
