Hand Applied Polyurea Waterproofing

Hand-applied polyurea waterproofing is a liquid, two-component coating applied manually to create a seamless, flexible membrane. It offers rapid curing, superior chemical, abrasion, and temperature resistance. Ideal for detailed areas or smaller applications, it provides reliable protection against water infiltration and extreme conditions. It’s uses are expanding due to its seamless and fast-curing properties. Organizations like the Polyurea Development Association (PDA) provide valuable resources on formulation advancements and best application practices. This method is suitable for applications such as water tanks, basements, and roofs requiring precise, custom application.
