Alignment of ceilings is a rule, absolutely any ceiling must be thoroughly leveled before applying building material to it. The fact is that today almost any ceilings require alignment, since builders during the construction of the house are far from always conscientious about this, as a result of which you can find any irregularities in almost any apartment. First of all, the ceiling must be primed. The fact is that the primer is well absorbed into concrete and provides good adhesion to the material. Next, putty is applied, which actually levels the surface. After the putty dries, you can proceed directly to the whitewashing or painting the ceiling.
