Product Description
TDW-666 nano-permeation waterproofing agent is composed of inorganic silicate.
Enhances the density and impermeability grade of concrete, applicable to both the
water-facing and water-receiving surfaces.
Waterproof, anti-seepage, and moisture-resistant, effectively removes wall alkali
whitening and effortlessly solves the problem of slow seepage caused by wall sweating.
Scope of Application
It is suitable for waterproofing and anti-seepage of cement concrete or mortar on both the water-facing and water-receiving surfaces.
Technical Specifications

| 9 | Carbonization resistance value/% | 7d | ≥30 |
| 28d | ≥20 | ||
| 10 | hydrophilicity of concrete surface | cannot roll in a beaded manner | |
Construction Operations
- Confirm operation range: Ensure safety and verify the operation area. Note: Do not operate when temperatures are below 5°C or above 40°C.
- Waterproofing base repair: For cracks wider than 0.3mm, fill them with waterproof mortar.
- Note: Use cement-based repair materials;
- Base surface rinsing and wetting: Use high-pressure water gun to rinse the base surface;
- Remove the floating slurry and oil stains on the surface, and moisten the base surface;
- The base plane is in a state of saturated surface dryness;
- First coat application: When the substrate surface is dry, apply the first coat at a rate of 150ml/m².
- Watering: After the material has been absorbed (approximately 20–30 minutes), water should be applied to promote its penetration.
- Apply the second coating after water absorption (approximately 20-30 minutes), using 100ml/m².
- Water spray and surface cleaning: After the material has been fully absorbed and the surface is dry (about 30-40 minutes), spray water to clean the surface.
- Moisture maintenance: If the concrete interior is relatively dry, it should be watered and maintained for at least 3 days.
Reference dosage
The theoretical dosage of TDW-666 nano-penetration waterproofing agent is about 250ml/㎡.
Important Notes
Matters need attention
