18L K11 Single-Component Flexible Waterproof Coating
Product Description
Product Name
K11 Single-Component Flexible Waterproof Coating
Brief Introduction
A ready-to-use, water-based waterproof coating designed for indoor and outdoor construction. After application, it forms a continuous, flexible, and seamless waterproof membrane on properly prepared concrete, cement render, masonry, and other compatible substrates.
Its low-VOC formula and convenient single-component design make it suitable for residential decoration and commercial waterproofing projects.
Core Advantages
- Single-component formula with no separate powder mixing required
- Flexible membrane bridges substrate cracks up to 2 mm
- Strong adhesion to cement, concrete, masonry, and compatible boards
- Good water and immersion resistance for wet and underground areas
- Low-VOC, low-odor formula suitable for indoor applications
- Weather-resistant performance for balconies and localized roof waterproofing
Applications
Suitable for waterproofing:
- Bathrooms and toilets
- Kitchens and utility rooms
- Balconies and terraces
- Basements and underground areas
- Swimming pools and water-retaining structures
- Localized rooftop areas
- Interior and exterior concrete or masonry substrates
For swimming pools, rooftops, and continuously immersed areas, application must follow the specified system design, coating thickness, reinforcement, and protective-layer requirements.
Mixing and Dilution
Ready to use after thorough stirring. If required for the first coat or a highly absorbent substrate, dilute with no more than 10% clean water by volume.
Do not exceed the recommended dilution ratio, as excessive water may reduce membrane thickness and waterproofing performance.
Storage and Shelf Life
Keep the bucket tightly sealed with its leak-proof inner plug. Store in a cool, dry, and well-ventilated place at 5°C–35°C. Protect from freezing, direct sunlight, and prolonged exposure to high temperatures.
Shelf life: 12 months when stored unopened under recommended conditions.

Application Instructions
1. Substrate Preparation
Ensure that the substrate is solid, flat, clean, and free from standing water. Remove dust, oil, laitance, loose particles, and other contaminants. Repair cracks, holes, and uneven areas with suitable repair mortar.
Reinforce internal corners, pipe penetrations, floor drains, joints, and other vulnerable areas before full-area application.
2. Stir Thoroughly
Stir the coating thoroughly until uniform. If necessary, add no more than 10% clean water by volume and mix completely.
3. Apply the First Coat
Apply an even coat using a roller, brush, or suitable spraying equipment. Maintain consistent coverage and avoid missed areas, pinholes, sagging, or excessive accumulation.
4. Apply the Second Coat
After the first coat has dried, apply the second coat in a direction perpendicular to the first. Additional coats or reinforcement fabric may be required at corners, joints, cracks, and pipe penetrations.
5. Curing and Water Testing
Protect the completed membrane from rain, water, impact, and foot traffic during curing. Allow approximately seven days of curing under normal conditions before conducting a water-retention test or applying subsequent protective and finishing layers.
