In each house, the walls are uneven initially. Who has at least once engaged in wall decoration familiar with this problem. Cavities, voids, waves on the surface of the walls give the impression that the builders did not really try when joining the plates. Now houses are most often sold in the form of a building version and are not spent on its finish.
In order for the apartment to meet the standards such an operation as wall alignment cannot be avoided. What the walls are covered in the future does not matter. Even if the owner of the apartment or house is going to finish them with panels of the walls to align them. The panels are mounted on horizontally located wooden rails. If the wall is not a flat panel, it cannot be fixed.
The walls in any case should be smooth and even.
To align the walls use putty. The more curve, the more you need. The most common type of putty today is vetonus. This is a dry powder, which after adding water turns into a paste. The vetonite is perfectly combined with the ratio of “price-quality”. There are more expensive types of putty. They are more plastic, which means it is more convenient and easier to work.
The amount of putty depends on how much walls are curves. You have to be prepared for the fact that it may need a lot.
