Can you correctly choose the right wall paint? The following is the welfare time, teach you how to choose the wall paint Let's have a look at the "little white" of home decoration! Classification and performance of wall paint 1 Four categories of wall paint Wall coating can be divided into different categories according to different standards Specifically, it can be classified according to the four dimensions of substrate, decoration effect, use position and use function According to the substrate: can be divided into organic coating, inorganic coating, organic-inorganic composite coating Among them, organic coatings include solvent, water emulsion and water-soluble organic coatings, while inorganic coatings include traditional cement, lime, etc According to decoration effect: it can be divided into flat and smooth surface coating, sand wall coating with sand like decoration effect on the surface, and multi-layer coating with three-dimensional decoration effect of concave convex pattern According to the use area: it can be divided into interior wall coating and exterior wall coating According to the use function: it can be divided into decorative coating, special functional coating (such as fireproof coating, mildew resistant coating, waterproof coating, elastic coating, etc.) A variety of coating categories are derived from the arrangement and combination of these four dimensions In general, the base material and application area are often combined to name the coating, such as solvent based exterior wall coating, water-soluble interior wall coating, inorganic exterior wall coating, etc PS: now the wall paint on the market is mainly latex paint Latex paint is one kind of organic coatings It is a kind of waterborne coating made of synthetic resin emulsion, which is made up of pigments, fillers and various auxiliaries Compared with other wall coatings, it is more environmentally friendly, and there is no danger of explosion and fire during transportation and storage At the same time, it has the advantages of convenient construction, fast drying, good air permeability and water resistance 2 The four major performance indicators of wall paint wall paint have a variety of indicators to determine its quality The following mainly lists the covering power, adhesion, viscosity and fineness, which have a great impact on the quality Through the understanding of these indicators of paint, there will be some basis for the inspection of paint quality Covering power: evenly coat the color paint on the black and white grid, and observe the minimum amount of paint used to cover the grid The larger the paint quantity is, the weaker the covering power is The stronger the covering power is, the less the paint quantity per unit area is Adhesion: the adhesion between the coating film and the base course, and the firmness of the combination of the coating film and the coated surface through physical and chemical action (the coated surface can be either the bare substrate or the painted substrate) The wall paint with weak adhesion is easy to fall off, affecting the appearance of the wall Viscosity: the viscosity of a coating, which can be measured with a paint viscosity measuring instrument Viscosity is an important index of coating performance, which has a great influence on the storage stability, construction performance and film-forming performance of coating Too thick paint is not easy to brush, too thin is easy to fall, so the viscosity of the paint should be controlled within a certain range Fineness: the size of particles in the coating and the degree of uniformity of dispersion Fineness directly affects the smoothness, luster and water permeability of the coating surface Generally speaking, the finer the coating, the more expensive it is There are five misunderstandings in the purchase of wall paint: pay attention to the price and ignore the quality Some consumers think that the higher the price of wall paint is, the better it is So when choosing the most expensive one, but the experimental results show that this is not the case In order to save money, the other extreme consumers feel that the lower the price is, the better Although they save a lot of money, the quality of the wall and the indoor environment will be worrying Therefore, we should pay more attention to the quality of wall paint when considering the price Generally, choosing a reputable brand can reduce the risk of being cheated Mistake 2: pay attention to packaging, ignore the wall paint with bad internal packaging, the quality may not be good, but the paint with good packaging may not be of good internal quality In order to attract customers, some manufacturers exaggerate the performance and efficacy of products on the packaging Therefore, consumers should pay attention to other aspects when looking at the product packaging, such as the detailed inspection sheet of the product Error 3: color card and wall paint color are exactly the same Many consumers think that the color of the paint on the color card is exactly the same as the color of the painted wall, which is actually a mistake Because of the reflection of light and other reasons, after the four walls of the room are painted, the color of the wall will look darker than the color card Therefore, it is suggested that when choosing colors through the color card, you should choose a color number that is a little lighter than your favorite color Myth 4: many consumers are not used to estimating the amount of paint in advance, and they are always afraid of less paint, so they are always better when purchasing This may cause waste of materials and increase the cost of home decoration At the same time, the accumulation of too much paint will also have a certain impact on the construction safety This requires us to look at the area of the construction area before construction, so as to estimate the amount of materials purchased Mistake 5: odorless wall paint is environmental protection Many people judge the safety of wall paint by smelling the odor, and think that low-quality or odorless wall paint is environmental protection But this is a big mistake, because odour can be achieved by adding flavors or using low flavor materials, so the odourless paint is 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 Decoration related knowledge recommendation: home decoration is very complex?
