Is there any impact on laying solid wood floors after ground leveling and desertification with self

First of all. You have to determine whether your rough floor needs to be paved with wooden keels, and if not, the ground needs to be leveled. But only the mason master is needed to level with cement mortar, and a layer of film will be laid on the ground before the floor is laid, as long as there is no sand and gravel on the ground.

There is basically no impact, because the installation of solid wood floor is to play the ground grille, it is to the ground level, there is no big requirement for the leveling material, when installing the floor grille, to play a percussion drill, install the floor nail, the floor nail is directly nailed into the floor, and it has nothing to do with the leveling layer. At most, the screed layer is uneven, and the workers add wood chips, and it doesn't matter if the sand rises! (As long as the overall surface layer is flat, and the leveling layer is not thick, it has no effect on the installation of floor nails).
