Superior Blue PU Coating Formulated for Basements Tenacious Adhesive Shield
Product Description
| Product Name | Polyurethane Waterproofing Coating |
| Material | Polyurethane |
| Color | Red Black Blue |
This ready-to-use, single-component coating is created from a high-grade blend of isocyanates and polyols, resulting in a sag-resistant, self-leveling product fortified with key additives. It achieves a seamless film and uniform thickness in one spray coat, including on vertical surfaces. It offers flexible application via spraying, brushing, or rolling.



Application
- Proven performance for foundations, terraces, wet rooms, patios, reservoirs, underground parkings, and protected rooftops.
- Engineered for industrial & civil infrastructure: food silos, protective shelters, and various bridge decks.
- Upgrade and safeguard exposed metal roofing systems.
Advantages
- Engineered for spray, application is remarkably efficient; the atomized spray fills micro-imperfections to prevent pinholes, creating a superior waterproof barrier.
- Its non-sag formulation guarantees a consistent film build on vertical surfaces, eliminating drips and irregularities.
- The CAS waterborne epoxy primer enhances substrate adhesion, securing a tenacious bond for the PU layer even on damp or difficult surfaces.
- The flexible coating elongates to accommodate structural movement and effectively bridges cracks without splitting.
- It delivers an outstanding moisture barrier and is resistant to degradation from UV exposure or fungal growth.
- To create a secure mechanical key for final finishes, broadcast silica sand onto the surface while it is still tacky before tiling or plastering.
