When repairing exposed concrete, the following precautions should be taken:
During construction, the environmental temperature should comply with relevant specifications and regulations to ensure the quality of the repair.
2. Repairs should continue until the repair material reaches the initial setting state, without any interruptions. For larger repair areas, layered construction is required, with each layer being tightly bonded together.
Before repairing, brush or chisel around the concave defects to expose the base material thoroughly. Additionally, clean the surface of the plain concrete and keep it moist before repair.
During the repair process, always observe and ensure the repair material matches the original color of the base material. If color discrepancies arise, conduct a secondary repair immediately.
5. The choice of repair materials should be determined based on the specific repair area and location. If the repair area is large, consider adding expanders or other additives to ensure the quality of the repair.
After the repair is completed, the surface should be thoroughly cleaned and then coated with maintenance agent or covered with a protective film to ensure proper curing of the repaired area.
Employees must strictly adhere to safety operation procedures and wear protective gear to ensure the safe execution of repair work.
In summary, the repair process for exposed concrete requires strict control over construction procedures to ensure the quality of the repair meets requirements, while also paying attention to safe operation.
