WP7-501 Basement + Wall Waterproof - Polymer cement coating - Tec7
The Tec7 WP7-501 Wall + Basement Waterproof is a high-performance polymer cement coating designed to provide 100% waterproofing for damp or wet basement walls and floors. This hard yet elastic coating is ideal for sealing areas affected by moisture, salt efflorescence, mold, or crumbling plaster. Once cured, it can be tiled, plastered, or painted over, offering versatility for various finishing options.
Features:
- Complete Waterproofing: Achieves 100% waterproofing from a minimum 2 mm layer.
- Salt Resistance: Resistant to salt efflorescence, making it suitable for areas prone to moisture-related issues.
- Crack Bridging: Offers crack-bridging capabilities, accommodating minor movements in the substrate.
- Vapor Permeable: Allows the substrate to breathe, reducing the risk of trapped moisture.
- Permanent Immersion Resistance: Suitable for areas that may be permanently submerged in water.
- Surface Compatibility: Can be tiled, plastered, or painted over once cured.
