K11 General Purpose Waterproof Coating is a reliable two-component polymer cement-based waterproof slurry, composed of polymer emulsion liquid and special cement powder with functional fillers.

After mixing liquid and powder at specified ratio, apply on cementitious substrates. Once cured, it forms a rigid-slightly flexible waterproof film. It has excellent adhesive strength to concrete, cement mortar. Breathable coating allows substrate vapor to escape.
It is the most popular general waterproof material for wet rooms. Widely used by contractors across West Africa for residential and commercial indoor waterproofing.

K11 general purpose coating is the standard workhorse for indoor wet area waterproofing. It bonds firmly to cement base. Tiles can be tiled directly on cured K11 layer. Suitable for tropical indoor construction, simple mixing and easy training for local workers.

✅ 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.
• Stable formulation adapted to tropical climate construction.
• 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: Clean substrate thoroughly, remove dust, loose mortar, oil and moss. Repair cracks and holes before coating.
2. Substrate can be damp, but must have no standing water before application.
3. Mix liquid and powder strictly by recommended ratio. Stir fully until lump-free slurry. Do NOT add extra water.
4. Apply first coat evenly, let it fully cure.
5. Apply second cross coat after first coat cures. Two coats are normally recommended.
6. Use mixed slurry within pot life. Protect fresh coating from rain before complete curing.

We can send construction tutorial videos once you send inquiry.

Q: Can K11 general coating be used on damp cement walls/floors?
A: Yes, damp substrate without ponding is acceptable, which saves waiting time on construction sites.

Q: Can I tile directly over cured K11?
A: Yes. After full curing, you can apply tile adhesive and tile directly on the K11 waterproof membrane.

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 1.4–2.0 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
