Polyurethane waterproof coating is premium elastomeric waterproof material. After curing, it forms a continuous, seamless, rubber-like waterproof membrane.

It features ultra-high elongation, high tensile strength, excellent crack bridging property. The dense membrane provides reliable waterproofing, anti-seepage and anti-corrosion performance. Good bonding to concrete, cement mortar, metal and many other substrates.
It is widely used for roof renovation, basement, reservoir and heavy-duty waterproof projects in tropical areas of West Africa.

• Concrete flat roof, terrace waterproofing and renovation
• Basement, underground structure anti-seepage waterproof
• Water tank, reservoir, swimming pool heavy duty waterproof
• Bridge, viaduct and industrial plant waterproof works
• Pipe roots, expansion joints, flashing node reinforcement
• Old roof leakage repair for residential & industrial buildings

Polyurethane coating creates dense, non-porous rubber membrane. It can stretch when substrate cracks, preventing recurring leaks. Good chemical resistance, suitable for heavy-duty waterproof projects. Popular for large commercial and industrial projects across tropical Africa.

✅ We are not a simple trading company — We are manufacturer + waterproof engineering contractor

Guangzhou Jiabaili Waterproof Engineering Co., Ltd. owns production factory in Baiyun District, Guangzhou. We integrate R&D, raw material compounding, mass production and construction technical service.

• Factory direct supply: Stable production, competitive pricing for full container bulk orders.
• Rich practical site experience. We fully understand the needs and difficulties of African contractors.
• Formula optimized for tropical high-temperature construction environment.
• Complete document package: MSDS, TDS and test reports for customs clearance & tender bidding.
• Free technical support: Our engineers share construction guides, area calculation and leak repair solutions.
• Sample service: Test kits available so buyers can test material performance locally before bulk purchase.

We cooperate with distributors, building contractors and project owners across Africa. We understand your market demand, shipping issues and on-site construction challenges.

1. Surface preparation: Substrate must be solid, clean and dry. Remove dust, loose mortar, oil and moss. Repair cracks and holes in advance.
2. Substrate moisture should be controlled. Standing water is not allowed. Wet surface will affect curing effect.
3. For two-component type: Mix component A & B fully as required ratio. Stir thoroughly, do NOT add extra water. For one-component, just stir evenly before use.
4. Apply first coat evenly, let it fully cure.
5. Apply second cross coat after first coat cures. Two coats are normally recommended.
6. Finish mixed material within pot life. Protect fresh coating from rain before complete curing.

We can send construction tutorial videos once you send inquiry.

Q: Can polyurethane coating bridge large roof cracks?
A: Yes. Thanks to ultra-high elongation. It can follow minor substrate movement and bridge micro cracks, solving recurring roof leakage caused by thermal expansion.

Q: Can polyurethane be used for water tank waterproof?
A: Yes, suitable for reservoir and water tank heavy-duty anti-seepage. Please choose proper grade for potable water if drinking water tank.

Q: Can I get samples for local testing?
A: Yes, sample kits are available. Contact us for sample cost and freight quotation.

Q: What is the coverage rate?
A: Around 1.0–1.5 kg per square meter for two coats. Actual consumption depends on substrate roughness. Our team can calculate total quantity once you provide your project area.

We can provide complete documentation set upon request:

• Material Safety Data Sheet (MSDS)
• TDS Technical Data Sheet
• Third-party performance test reports

These documents support import clearance and project tender bidding. Send inquiry and we will email all documents to you.
