A construction method of a fiber lining surface of an ethylene cracking furnace includes the following steps: S1, leveling the fiber lining surface; S2, wetting the leveled fiber lining surface; S3, rooting the wetted fiber lining surface; and S4, coating, before the fiber lining surface is dried, high-temperature paint to the fiber lining surface that has been rooted; and reserving multiple expansion sews on the fiber lining surface during the coating process. According to the construction method of the high-temperature paint for full fiber lining structure of the ethylene cracking furnace, the high-temperature paint is firmly bonded with the lining, and will not crack or fall off during use, protecting the full fiber lining by the coating and greatly extending the service life of the lining.
