Polyurethane waterproof is a liquid-applied coating used for sealing gaps and joints. It is resistant to water, chemicals, and UV rays, making it ideal for use in various environments. It is also known for its flexibility, allowing it to accommodate movement within building joints while providing a strong and durable seal. To select the right PU waterproofing for your project, consult its technical data sheet (TDS). It will indicate the scope of the application and other details, such as the temperature range and breathability.
In addition to the TDS, check the manufacturer’s website for specific instructions on applying the product. You will need to have the right tools, such as a mixer and sprayer, as well as a suitable surface to apply the product on. The substrate should be dry and clean to ensure the waterproofing membrane will bond properly. For concrete surfaces, a primer is recommended before the application of a PU waterproofing coating. The product should be mixed well before use and sprayed onto the concrete with a roller or brush, according to the manufacturer’s instructions.
Polyurethane Waterproofing: A Comprehensive Guide
Compared to polyurethane waterproof, thermoplastic membranes are not as flexible and may not be appropriate for structures that require great movement. Also, they are susceptible to deterioration when exposed to high temperatures over an extended period of time and certain chemicals. To overcome these disadvantages, you should consider using a hybrid or pure polyurea waterproofing membrane like Synthesia’s Urespray range. This is a liquid applied hybrid-polyurethane-based coating that can be applied to any surface with excellent performance, resistance and elasticity.
