Product type
Bituminous waterproof coatings are protective materials primarily used to create a waterproof barrier on various surfaces. These coatings are made from bitumen, a viscous, black, tar-like substance that is derived from petroleum. They are typically applied in liquid form and cure to form a durable, flexible membrane that effectively prevents water ingress. Commonly used in construction, they are ideal for roofs, foundations, and below-grade applications.
| Material | Bitumen-based compounds |
| Application method | Brush, roller, or spray |
| Cure time | 24 to 48 hours, depending on conditions |
| Temperature range for application | Above 5°C (41°F) |
| Thickness after curing | 1 to 3 mm |
| Water resistance | Excellent, withstanding hydrostatic pressure |
When selecting bituminous waterproof coatings, consider the specific application requirements, such as the surface type and exposure conditions. It is important to specify the desired thickness, curing time, and any necessary certifications for environmental compliance. Quantities should reflect the area to be covered, taking into account the manufacturer's coverage rates and any additional layers that may be required for optimal performance.
