In home furnishings, wall decoration is a key project that directly affects the decoration style of the entire home. Material selection, construction preparation, and how to construct are all important parts of wall painting. In these construction processes, there are often some misunderstandings. These misunderstandings may be caused by habits or caused by unfamiliar materials and engineering. In this issue, Xiao Bian asked everyone to understand the mistakes in wall decoration and to understand it together.
I. Misunderstandings in construction cannot be ignored
The construction process is the focus of the wall decoration, the construction details are done well, and the renovated wall looks beautiful and durable. However, there are many misunderstandings in the construction process. These misunderstandings are often committed by the owners and some inexperienced masters.
Myth # 1: The more paint times, the easier it is to paint off
Some people think that the more times the wall is painted, the thicker the wall paint is, the easier it is to paint off. In fact, there is no direct relationship between the situation of brushing and the number of times of brushing. It is only related to the degree of humidity in the room.
Xiao Bian Weapons: The general quality of the paint even after brushing 10 times, 20 times, will not appear out of paint. Only when the putty is wet and loose will cause the wall to lose paint. In this case, paint 1 - 2 times paint will fall. Brush the primer on the regular common wall again and paint it twice. If the dark paint can be brushed several times.
Myth 2: The paint must be filled with water to paint
Many people have the impression that the use of paint is that water must be added to brush off the paint. Therefore, many people add a lot of water before painting. This idea and practice are incorrect. In fact, any paint that does not add water can also be brushed off with a roller, but without adding water, it will leave a knurled print on the wall.
Xiao Bian Weapon: In the wall painting construction, the general light-colored paint can add some water to dilute and then brush. However, dark paint does not need to add more water, because its poor coverage, if you add water when rolling, it is easy to brush the wall. In this way, for the same area of ​​the wall, the amount of dark paint is double that of the light paint.
Myth #3: The darker the paint brush, the darker the paint
Many people think that the more times a dark paint is applied, the darker the color will be. Therefore, when painting a wall, owners who want to deepen the color of the wall often require construction workers to brush several times more paint to make the wall look darker. In fact, this approach is incorrect.
Xiao Bian Weapon: Dark paint even if it is painted more than 10 times, the color will not become deeper. Dark paint contains lower content of titanium dioxide, less covering power, and can be brushed several times more than light-colored paint, but generally it can be controlled in 5-6 times. Too many brushings increase the thickness of the wall paint, which in turn may cause surface cracking.
Myth 4: Spray is thinner than roller paint film
Many people believe that the spray paint film is thinner than the roll paint film. In fact, this view is not entirely correct. The thickness of the paint film depends on the number of times of construction and the amount of water added. There is no direct connection with the method of spraying or roller coating.
Xiao Bian Weapons: spray paint is divided into two methods of air spray and high pressure airless spray, in the case of the same number of spray times, air spray paint film is thinner than the paint film, but the high pressure airless spray The paint film is thicker than the roll paint film. Therefore, the thickness of the paint film is not directly related to the choice of spray or roll coating.
