Key Features
Combining rigidity and flexibility, it balances structural stability and adaptability to micro-cracks in the substrate.
High adhesion, excellent water and weather resistance.
Multi-layer Coating creates a monolithic waterproof membrane.
Water-based, environmentally friendly, low odor, and safe to apply.
Suitable for waterproofing projects such as roofs, walls, underground structures, and bathrooms.
Applications
Roof, balcony, and terrace waterproofing
Bathroom, kitchen, and basement waterproofing
Pool, water tank, and reservoir waterproofing
Concrete, mortar, and other building substrates waterproofing
Application Instructions
1. The substrate should be firm, flat, dry, and free of loose dust, oil, or loose materials.
2. Mix components A and B thoroughly and evenly before application.
3. It is recommended to apply in two or more coats of paint, each approximately 0.5mm thick. Allow the previous Paint to dry before applying the next.
4. Application temperature: 5–35°C, relative humidity <85%, and avoid erosion by rain. Apply at 5–35°C, RH <85%, avoid rain washing.
5. After application, the waterproof membrane requires curing for at least 7 days. Keeping it moist improves performance.
Applications
Suitable for waterproofing roofs, balconies, basements, bathrooms, pools, and various building structures. It is particularly suitable for areas subject to minor structural deformation.
