Wrong choice of paint 1: anti crack paint must be anti crack
No matter new house or old house, the phenomenon of wall cracking is very much. 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.
It is impossible that a thin film of paint can prevent the wall from cracking. 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.
Wrong choice of coating 2: blindly worrying about environmental protection of coating
As people pay more and more attention to health, many people are not afraid of fakes but 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.
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.
Wrong choice of coating 3: too much attention to the brand of coating
Many owners think that buying paint is good for buying famous brands. Of course, the products of famous brands have certain quality assurance, but they cannot blindly pursue the brand. 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.
When choosing coatings, we should first understand the quality, reputation and market of various brands of coatings on the Internet or other channels. Paint with the same effect, try to choose the brand with reasonable price.
Wrong choice of coating 4: more materials is better
Many owners are afraid to buy less paint, so 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 paint in the construction site also has a certain impact on the construction safety.
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.
Five mistakes in coating selection: no smell is environmental protection
Many people judge the safety of the wall paint by smelling the smell, and think that the wall paint with low odor or no smell is environmental protection. This is a big mistake. Because odors can be achieved by adding flavors or using low flavor materials, so odorless coatings are not environmentally friendly and non-toxic. The most professional way to judge the environmental protection of wall paint is to see whether its environmental protection indicators meet the standards. There are three key environmental indicators of wall paint: VOC, free formaldehyde and heavy metal.
No matter what kind of decoration, coating is one of the indispensable decoration materials, and with the progress of decoration construction technology, the innovation of decoration materials, the choice of decoration materials is more and more important, especially the choice of coating is the most important. Owners and friends in the choice of decoration paint must be clear about the above five mistakes, so as to ensure the quality of paint and family health.
