Building Waterproof Renovation - Application Of Spray Polyurea Protective Coating

Project Background:

An old residential building located in a coastal city suffered severe water infiltration due to long-term exposure to sea breeze erosion and rainwash, leading to indoor wall mold and peeling, seriously affecting residents' living environment and structural safety of the building. Considering the historical value of the building and residents' living needs, the project team decided to use spray polyurea protective coating for waterproof renovation.

Solution:

The renovation project first cleaned the dirt and old coatings on the roof and exterior walls to ensure a clean and dry substrate. Subsequently, a professional spray equipment was used to uniformly spray the polyurea protective coating onto the roof and exterior walls, forming a continuous, seamless, and highly elastic waterproof layer. Polyurea coating not only exhibits excellent waterproof performance but also possesses outstanding weather resistance, corrosion resistance, and abrasion resistance, effectively withstanding the erosion of sea breeze, salt spray, and other harsh environments.

Outcome And Impact:

After the renovation, the residential building's roof and exterior walls were completely free of water infiltration issues, and the indoor environment was significantly improved, enhancing residents' quality of life. At the same time, the high elasticity and durability of the polyurea protective coating ensured long-term protection of the building from external environmental damage, extending its service life and providing an effective waterproof solution for the preservation of historic buildings in the city.
