Four major misunderstandings of paint construction: it is no longer difficult to get out of the wrong zone!
Many people think that the more times the paint on the wall is painted, the easier it is to paint. However, this is actually a big mistake. The wall will be lacquered, which is completely irrelevant to the thickness of the paint film and the number of times the paint is applied. It is only related to the degree of humidity in the room.
Going out of the misunderstanding: If the quality of the paint passes, the humidity in the room is suitable, then even if it is painted ten times or twenty times, it will not fall off the paint. On the other hand, if the wall is wet, even if you only brush the paint twice, the paint will fall off. Generally, the wall decoration is painted three times, and the primer is applied once and the top coat is applied twice.
Myth 2: The paint must be added with water to coat
Paint must be mixed with water, which is what most people think. Therefore, many people will mix water in the paint before painting on the wall, but in fact, any paint can be smeared with a roller brush without adding water. The water is added only to make the seal of the roller brush not stay in the wall. on.
Going out of the misunderstanding: whether the paint is mixed with water is mainly the color of the paint, and the light color needs to add water, because the light color of the wall will be more obvious if it leaves the roller. If you use dark paint, you don't need to mix water, because the coating itself is poorly covered. If you add water, the painted wall will be deep and shallow. This is why the amount of light-colored paint on the wall of the same area is less, and the amount of dark paint is almost double that of light-colored paint.
Myth 3: The more dark paint brushes, the darker the color
Many people think this way: the dark paint is painted a few times, then the color of the wall will be deeper and deeper. Therefore, some owners who like dark colors will ask them to brush the paint several times during the construction of the workers, and think that the color of the wall will be deeper. But this approach is very undesirable.
Going out of the misunderstanding: the color of the wall depends only on the color of the paint, not on the paint applied several times. Although the dark paint has a low content of titanium dioxide and poor coverage, it needs to be painted several times, but this number is controlled in five or six times. Too much coating will only increase the thickness of the wall, causing problems such as cracking.
Most people think that the painted film is much thinner than the roll-painted film, but this is just an unfounded guess. The thickness of the paint film is only related to the number of times of painting and the amount of water added, regardless of the way the brush is applied.
Out of the misunderstanding: there are two main ways of spraying, air spraying and high pressure airless spraying. The film thickness of air spray, high pressure airless spray and roll coating was measured using the same paint and the same number of times of painting. As a result, the air sprayed paint film was thinner than the roll paint film, but The high pressure airless spray paint film is thicker than the roll paint film.
