Material selection, construction preparation, and how to construct are all important parts of wall painting. In these construction links, there are often some misunderstandings, which may be caused by habits or unfamiliarity with materials and engineering. Here we talk about the common misunderstandings of wall painting, so that you can be smartly decorated.
Misunderstanding 1: Anti-cracking paint will definitely resist cracking
Regardless of the old house in the new house, the phenomenon of cracking the wall is very much. Many people have tried their best to choose a good paint to solve the cracking problem. I have seen a famous brand of paint packaging that says "anti-cracking". Many consumers think that as long as they use these paints, they can prevent wall cracking and other problems. In fact, this does not have much effect.
Weapons: A thin layer of paint film can prevent the cracking of the wall, which is unlikely. The "elastic latex paint" currently on the market generally only compensates for microcracks below 0.3 mm. If the wall has been cracked and you want to solve these problems, it is best to use latex paint to make up, or use cement to fill the cracks and paint.
Myth 2: Blindly worry about the environmental protection of paint
As people pay more and more attention to health, many people are not afraid of fake goods but are afraid of decoration pollution. When it comes to decoration pollution, many people immediately think of paint. Everyone thinks that the paint contains a lot of toxic substances such as formaldehyde, benzene, VOC, etc. Therefore, when choosing the paint, it is also very worried. But in fact, this kind of worry is not necessary. Nowadays, the safety of many coatings has reached a good level, and consumers do not have to worry too much.
Weapons: In fact, many consumers' concerns about the environmental protection of paint can be said to be blind. Most qualified indoor wall coatings are safe now. They are generally water-based paints. Environmentally-friendly water-based paints produce less harmful substances such as formaldehyde and benzene. Generally, they are less harmful to the human body. Effectively avoid these decoration pollution.
Myth 3: Over-conscious about the brand of paint
Many owners think that buying paints is good for buying well-known brands. Of course, well-known brands have certain quality guarantees, but they cannot blindly pursue brands. In fact, the quality and effect of many common brand products and well-known brand products are not much different, but the price has a gap. It is a wise choice to choose a paint.
Weapons: When selecting paints, you should first understand the quality, reputation and market of paints of various brands in the network or other channels. For coatings with the same effect, try to choose a brand with a reasonable price.
Myth 4: Buying more materials is good
Many owners are afraid to buy less paint. Therefore, they bought a large amount at the beginning. In fact, this is a big mistake. This has caused waste of materials, which has affected the cost of the project. The construction site has accumulated too much paint for construction safety. Have a certain impact.
Weapons: Before construction, we must look at the area of ​​the construction area to estimate the amount of materials purchased. Usually, the materials purchased should be 10%-15% more than the budget, which can reduce the chance of re-purchasing materials and waste opportunities. Can be reduced to a minimum.
Myth 5: The more dark paint brushes, the darker the color
Many people think that the more the number of dark paints is applied, the deeper the color will come out. Therefore, when painting the wall, the owner who wants to deepen the color of the wall often requires the builder to brush the paint several times to make the wall look darker. In fact, this practice is not correct.
Tips: Even if the dark paint is painted more than ten times, the color will not become deeper. Dark paints contain low levels of titanium dioxide and are not very strong. They can be brushed several times more than light-colored paints, but they are usually controlled at 5 to 6 times. Too many paintings increase the thickness of the wall coating, which may cause surface cracking.
Myth 6: The wall is smooth and flat.
Some people think that when the wall is smooth, they think that the wall painting is very flat. In fact, this rough estimate is wrong, because the smoothness of the wall is not simply visible to the naked eye.
Weapons: Take the lamp with your hand for acceptance. Generally, use a wire to connect a 200W bulb. After the bulb is tied with a square of 80 cm long, you can take the bulb along the wall as long as the wall is uneven. Or the particles can be seen, and then keep the distance between the bulb and the wall at about 10cm, and then see with the naked eye whether the yin and yang angles are straight.
