Product type
Liquid waterproof membranes are specialized coatings designed to create a seamless barrier against water infiltration. They are typically made from polymer-based materials, such as polyurethane or bitumen, which provide flexibility and durability. These membranes are applied in liquid form and cure to form a robust waterproof layer that adheres well to various substrates.
| Material | Polyurethane, bitumen, or acrylic |
| Application method | Brush, roller, or spray |
| Curing time | 1 to 24 hours, depending on conditions |
| Thickness | 1 to 3 mm after curing |
| Temperature range | Application between 5°C to 35°C |
| Coverage | 1 to 2 kg per square meter |
When selecting a liquid waterproof membrane, consider the specific application environment and the type of substrate. It's important to specify the required thickness, curing time, and any necessary certifications for your project. Additionally, inquire about the product's resistance to UV exposure and temperature variations, as these factors can impact performance. Quantities should be estimated based on the coverage rate provided by the manufacturer.
