The invention relates to a wall surface leveling track and an installation method thereof. The wall surface leveling track comprises a wall surface fixed part fixed on a building wall surface, a wallboard fixed part and wallboard fasteners, wherein the wallboard fixed part is detachably fixedly connected with a wallboard base material layer by virtue of a wallboard clamping member; the wallboard fasteners are fixed at the end part of the wallboard fixed part and locked at the side end of a wallboard fixed plate in the length direction; the wallboard fixed part can slide back and forth along the length direction of the wallboard fixed part by virtue of the wallboard fastener; by virtue of the wall surface leveling track, the leveling be carried out on the building wall surface so as to improve the quality of the base material layer for installing a wallboard; moreover, by virtue of the wall leveling track, the wallboard base material layer can also be directly loaded and unloaded on thebuilding wall surface, thereby simplifying the loading and unloading process of the wallboard base material layer; and furthermore, since the wallboard base material layer is detachably mounted on the building wall surface by virtue of the wall surface leveling track, the wallboard base material layer is prevented from being damaged in the loading and unloading process, so that the wallboard basematerial layer can be reused.
