Core tip: material selection, construction preparation, and how to construct are all important links of wall painting In these construction links, there are often some misunderstandings, which may be caused by habits or unfamiliar with materials and engineering Talk about the common mistakes of wall painting, let you smart decoration Myth 1: anti crack paint will definitely crack no matter new or old houses, there are many cracks on the wall Many people are trying to choose a good paint to solve the problem of cracking Once upon a time, I saw the words "crack resistance" on the famous brand paint package Many consumers think that they only need the oil Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: the choice of materials, construction preparation, how to construct and so on are the important links of wall painting In these construction links, there are often some misunderstandings, which may be caused by habits or unfamiliar with materials and engineering Talk about the common mistakes of wall painting, let you smart decoration Myth 1: anti crack paint will definitely crack no matter new or old houses, there are many cracks on the wall Many people are trying to choose a good paint to solve the problem of cracking Once upon a time, I saw the words "crack resistance" on the famous brand paint package Many consumers think that as long as the use of these paints can prevent wall cracking and other problems, in fact, this is not very effective Tips: a thin layer of paint film can even prevent the occurrence of wall cracking, which is unlikely Now the "elastic emulsion paint" on the market can only make up for the microcracks below 0.3mm If the wall has cracked, the best way to solve these problems is to use latex paint to make up, or cement to make up the cracks, and then 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 but afraid of decoration pollution When it comes to decoration pollution, many people immediately think of paint We all think that there are a lot of formaldehyde, benzene, VOC and other toxic substances in the paint Therefore, when selecting the paint, we are also very worried But in fact, this kind of worry is unnecessary Now the safety of many coatings has reached a better level, and consumers do not need to worry too much Tips: in fact, many consumers are blind about the environmental protection of coatings At present, most of the qualified interior wall coatings are safe They are generally water-based coatings Environmental friendly water-based coatings produce less formaldehyde, benzene and other harmful substances, which generally do little harm to human body As long as the indoor ventilation is paid attention to after decoration, these decoration pollution can be effectively avoided Misunderstanding 3: many owners who care too much about paint brands think that buying paint is good for buying famous brands Of course, products of famous brands have certain quality assurance, but they cannot blindly pursue brands In fact, many ordinary brand products and well-known brand products have little difference in quality and effect, but there is a gap in price Reasonable choice of coating is a wise choice Tips: when selecting coatings, you should first understand the quality, reputation and market of various brands of coatings through the Internet or other channels Paint with the same effect, try to choose the brand with reasonable price Myth 4: buying more materials means that many owners are afraid to buy less coatings Therefore, they buy a lot at the beginning In fact, this is a big mistake, which leads to waste of materials, thus affecting the cost of the project Too much coating in the construction site also has a certain impact on the construction safety Tips: before construction, it is necessary to look at the area of the construction area to estimate the amount of materials to be purchased Generally, the purchased materials should be 10% - 15% more than the budget, which can reduce the probability of purchasing materials again and minimize the waste opportunities Myth 5: the more dark paint is brushed, the darker many people think that the more times dark paint is brushed, the darker the color will be Therefore, when painting the wall, the owner who wants to deepen the color of the wall often requires the construction personnel to paint several times to make the wall look darker In fact, this approach is not correct Tips: even if the dark paint is brushed more than ten times, the color will not become deeper The content of titanium dioxide in the dark paint is low, and the coverage is not strong It can be brushed several times more than the light paint, but it is generally controlled within 5 to 6 times Too many times of painting, so that the thickness of the wall coating increases, but it is easy to cause surface cracking and other situations Myth 6: smooth wall is flat Some people think that when they see the smooth wall, they think that the paint is flat In fact, such a rough estimate is wrong, because the smooth wall is not easy to see with the naked eye Tips: use a hand lamp to check and accept Generally, connect a 200W bulb with a wire After the bulb is tied with a 80cm long fine wood square, you can take the bulb along the wall As long as the wall is uneven or particles can be seen, keep the distance between the bulb and the wall at about 10cm, and then use the naked eye to see whether the internal and external corners are straight Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
