Application
The application of polyurethane liquid membrane waterproofing is quite simple and straightforward. First, the surface needs to be clean and dry. Second, the primer needs to be applied to ensure the adhesion of the liquid membrane. Third, the polyurethane membrane needs to be applied by using a brush, roller, or spray equipment. Fourth, it needs to be left to dry for a few hours, depending on the temperature and humidity. Finally, a topcoat can be applied to enhance the membrane's resistance and durability.
Advantage
One of the advantages of polyurethane liquid membrane waterproofing is that it does not have a significant impact on the environment. It is a solvent-free solution, which means it does not emit toxic gases or harmful substances. Furthermore, it is a low VOC (Volatile Organic Compound) product, which means it does not contribute significantly to air pollution. Therefore, it is an eco-friendly solution that can help you reduce your carbon footprint and contribute to a healthier environment.
