The time interval from the surface of the steel pipe of the polyethylene film tape to the primer before painting should be controlled within 6 hours. The surface of the steel pipe must be dry and dust-free. The primer of the polyethylene film tape should be evenly stirred in the container. When the primer is thickened, the thinner matching with the primer should be added to dilute the proper viscosity. The primer can be applied using a clean brush, roller or some other mechanical means.
The polyethylene film tape needs to wait for the primer to dry before it can be wrapped. Special attention should be paid to the long drying time when the temperature is low or during the trench construction to ensure the dryness of the lower part of the steel pipe. The time interval from the application of the primer on the surface of the steel pipe to the wrapping tape should be controlled within 8 hours. The surface of the primer should be dry and dust-free (when the sand is large or the air humidity is high, it should be wrapped immediately). If it is more than 8 hours or overnight, the primer should be repainted before wrapping the tape.
When using the primer film, the polyethylene film tape should be safe to prevent splashing and should be kept away from fire. After the primer is used, the remaining primer should be poured back into the original iron container and the container should be sealed to prevent the evaporation of the primer.
