K11 General Purpose Waterproof Coating
Cementitious Polymer Modified Slurry, Hard & Strong Waterproof Layer, Suitable For Wet Areas Manufactured by Guangzhou Jiabaili Waterproof Engineering Co., Ltd.
Forms rigid, tough cement-based waterproof layer after curing. Good abrasion resistance, can be tiled directly on top without extra interface treatment.
Vapour permeable cementitious coating. Water vapour inside substrate can escape, preventing blistering. Works well on slightly damp cement substrates.
Universal for bathroom, kitchen, basement, swimming pool base, balcony. Easy mixing and simple construction, popular for residential waterproof projects.
It bonds chemically with cement substrates. Once cured, the surface can receive tile adhesive directly. It is breathable and suitable for indoor wet areas where substrate movement is minimal. It is very widely used in residential construction across Africa, thanks to simple mixing procedure and low material cost. Formulated to perform stably under tropical high-humidity environments. It is the standard choice for bathroom, kitchen and basement waterproofing in new buildings and renovation works.

- Bathroom & shower room waterproofing for residential buildings
- Kitchen wet area waterproof treatment
- Basement internal wall & slab waterproofing (no large structural cracks)
- Balcony waterproofing where slab movement is limited
- Swimming pool base and tank internal pretreatment
- Internal masonry wall waterproofing before tiling
K11 general coating is the most common waterproofing material for indoor wet rooms. Important limitation: it is rigid. If the concrete slab has active cracks or thermal movement, the K11 hard layer may crack. For those moving substrates, super-elastic coating or JS flexible coating should be selected instead. Contractors in Ghana, Nigeria and West Africa widely choose K11 for standard residential bathroom jobs because it is economical, easy to apply and tiles can be laid directly on top.
✅ We are a professional waterproof manufacturer in Guangzhou, producing stable K11 polymer cement slurry optimized for tropical construction markets. Our formula balances powder-liquid matching ratio, provides good workability without sagging on vertical walls.
- Factory direct bulk supply, competitive price for full container orders
- Good mix consistency, smooth brushing, low sagging on vertical walls
- Full document package: MSDS, TDS and third-party test reports for import clearance & tender bidding
- Technical guidance for site workers: mixing ratio, corner reinforcement & ponding test steps
- Samples available, customers can test mixing performance, hardness and waterproof effect locally before bulk purchase
We supply a complete waterproof material portfolio for distributors and building contractors across West Africa. K11 works together with flexible coatings, wall primer and floor primer to build one-stop waterproof solutions for residential and commercial construction projects.
- Surface prep: Substrate solid, clean, free of loose mortar, dust, oil. Repair holes and large cracks before waterproofing.
- Mixing: Pour liquid component first, slowly add powder, stir uniformly until lump-free. Follow recommended mixing ratio strictly.
- Apply by brush or roller. Apply minimum two coats. Second coat applied crosswise after the first coat is touch dry.
- Pay extra reinforcement at corners, pipe penetrations and wall-floor junctions.
- Protect fresh coating from rain and strong wind before curing completed.
- After full curing, carry out water ponding test. Pass ponding test before tiling work.
We can send construction tutorial videos and corner reinforcement drawings on request.
Q: What is the main difference between K11 and super-elastic waterproof coating?
A: K11 forms a rigid hard cement layer, breathable and tileable directly, suitable for static substrates without active cracks. Super-elastic coating is flexible rubber membrane, can bridge micro cracks, used when slab has thermal shrinkage movement.
Q: Can K11 be used on fully exposed roof?
A: Not recommended for fully exposed roof under continuous direct sunlight. UV and repeated thermal expansion may crack rigid K11 layer. For exposed roof, silicone waterproof coating is preferred.
Q: Can I tile directly over cured K11?
A: Yes. Once fully cured, tile adhesive can be applied directly on K11 surface, no extra primer needed normally.
Q: What is coverage consumption?
A: Around 1.2–1.8 kg per square meter for two coats, depends on substrate roughness. Our sales team calculates exact consumption after receiving project area.

K11 Universal waterproof coating
I.Core Functions
-
Penetration Crystallization Waterproofing: The active ingredients in the slurry can penetrate into the capillary pores and micro-cracks of the cement base to conduct chemical reaction, generating insoluble dendritic crystals to block water seepage channels from the inside, forming a dense integrated waterproof layer. It also has waterproof function on the negative water surface.
-
Available for Construction on Wet Base: It can be directly constructed on wet base without waiting for the base to be completely dry, effectively shortening the construction period.
-
Convenient Follow-up Processes: There is no need to build an additional mortar protection layer after construction. Follow-up operations such as tile pasting, plastering and finish construction can be carried out directly, greatly improving construction efficiency.
-
Environmental Protection & Safety: It is a water-based product, non-toxic, harmless and pollution-free, which is a green environmental protection material. It can be directly used in scenarios directly contacting with water such as drinking water tanks and fish ponds. Meanwhile, it can inhibit the growth of mold and prevent the pollution of moisture and salt to the finish.
-
Impermeability, Crack Resistance & Compression Resistance: The crystals penetrate into the base material, endowing the waterproof layer with high impermeability and compression resistance. It can cover micro-cracks less than 0.4mm and resist slight structural vibration.

Ⅳ.Construction Method
-
Base Treatment: The base surface shall be firm, flat, clean, free of looseness, sanding, oil stains and open water. Obvious pores and sand holes shall be blocked and smoothed with cement mortar, and sharp edges, internal and external corners shall be treated as rounded corners. If the base is dry, sprinkle water to wet it in advance until there is no open water.
-
Material Mixing: According to the ratio of liquid component : powder component = 1:1.25, pour the liquid component into the mixing container first, then slowly add the powder component, stir fully with an electric mixer for 3-5 minutes until uniform paste without particles and sediment is formed. Intermittent stirring can be carried out during the operation to prevent slurry sedimentation.
-
Node Reinforcement: For special node parts such as internal and external corners, pipe roots, construction joints and junctions of different materials, carry out additional layer reinforcement treatment first, apply the slurry thickly on the node parts with a brush for sealing and leakage stopping.
-
Layered Coating: Brush the slurry evenly with a brush or roller, do not miss any area. Generally, 2 coats are required, and the thickness of each coat shall not exceed 1mm. The coating directions of the two coats shall be vertical and cross. The interval time shall be subject to the coating drying and non-sticky to hands, usually 1-2 hours. If the interval exceeds 24 hours and the coating is cured, wet the base fully with clean water first before the next coat.
-
Curing & Acceptance: After the construction is completed, avoid disturbing the coating before it dries. After curing for 24 hours at normal temperature, the water closed test can be carried out to accept the waterproof effect.
V.Packaging & Storage
-
Packaging Specification: Three specifications are available: 5kg/barrel, 10kg/barrel and 20kg/barrel, with matched two-component packaging.
-
Storage Conditions: The liquid component shall be stored in a cool and dry place above 5℃, avoid sunlight and freezing. The powder component shall be stored in a dry and ventilated place to prevent moisture.
-
Shelf Life: For unopened products, the shelf life is 12 months under the above compliant storage conditions.
