Wall paint can be divided into different categories according to different standards. Specifically, it can be mainly classified according to the four dimensions of the substrate, the decorative effect, the use location, and the usage function. The four-dimensional arrangement produces a variety of coating categories. In general, the substrate and the area of ​​use are often combined to name the paint, such as solvent-based exterior wall paint, water-soluble interior wall paint, inorganic exterior wall paint, and so on. Next Xiaobian introduced the purchase of wall paints and wall paints.
Wall paint purchase considerations
1, heavy price and ignore the quality
When many people buy wall paints, it is very easy to go into price and ignore quality mistakes. Some think that the higher the price of the paint, the better, so when it comes to choosing the most expensive to buy, but the experimental results show that this is not the case. The other extreme consumer is to save money. The lower the price, the better the time of purchase. This saves a lot of money, but the quality of the wall and the indoor environment in the future is worrying. Therefore, it is recommended that everyone consider the price as much as possible to pay attention to the quality of the wall paint, generally choose a reputable big brand.
2, heavy packaging and ignore the inner
Consumers always look at its packaging when it comes to purchasing latex paint. This is very necessary. However, it should be noted that a good-looking coating does not necessarily have an inherently good quality. In order to attract customers, some manufacturers make a big issue on the packaging of products and deliberately exaggerate the performance of products. Therefore, it is recommended that consumers not only look at the product packaging, but also pay attention to other aspects, such as checking the product's detailed test list.
3, color card and wall color exactly the same
Many consumers think that the color of the paint on the color card is exactly the same as the color on the wall. This is a misunderstanding. Because of light reflections and other reasons, after the walls of the room are painted, the color of the wall looks darker than the color card. The color the consumer sees on the color card and the actual color behind the paint on the wall are usually different. Therefore, it is recommended that consumers choose the color number that they like to be slightly lighter when selecting colors in the color card. If you like dark walls, they can be adjusted to the color of the selected color card.
4, do not estimate the amount of paint in advance
Many consumers do not estimate the amount of paint in advance, and fear that they will buy less paint. This may cause waste of materials, increase the cost of home improvement, and the accumulation of too much paint will also have a certain impact on construction safety. Therefore, it is recommended that consumers must look at the area of ​​the construction area before construction to estimate the amount of material purchased. The simple method for estimating the amount of paint used is to coat the required amount of paint (L) = (wall area x 2.5)/paintable area per liter of paint.
5, odorless is environmentally friendly
Many people judge the safety of wall lacquer by smelling the odor. They think that low odor or odorless wall lacquer is environmentally friendly. This is a big mistake. Because odors can be achieved by adding flavors or using low-taste materials, odorless coatings are not all environmentally friendly and non-toxic. The most professional way of judging the environmental protection of wall paints is to see if their environmental indicators meet the standards. There are three key environmental indicators for wall paint: VOC, free formaldehyde, and heavy metals.
Classification of wall paint
According to the substrate: can be divided into organic coatings, inorganic coatings, organic-inorganic composite coatings. Among them, organic coatings include solvent-based, water-emulsifying, and water-soluble organic coatings. Inorganic coatings include traditional cement, lime, and the like.
According to the decorative effect: it can be divided into flat and smooth surface coating, sand-like coating with sand-like decoration effect, and multi-layer coating for forming embossed pattern three-dimensional decoration effect.
By use area: can be divided into interior wall paint, exterior wall paint.
According to the use of functions: can be divided into decorative coatings, special functional coatings (such as fire-retardant coatings, anti-mold coating, waterproof coating, elastic coating, etc.).
Wall paint features
1. High hiding power: refers to the minimum amount of paint that is used to uniformly apply the paint to the black and white grid so that the black and white grid is no longer present, expressed in g/m2. The greater the weight is, the weaker the hiding power is, and the stronger the hiding power is, the less the amount of paint per unit area is used.
2, good fineness: refers to the size of the paint particles and the uniformity of the dispersion. Fineness size directly affects the smoothness, gloss, and water permeability of the coating surface. In general, the finer the paint, the more expensive it is.
3, strong adhesion: that the adhesion of the coating and the grass-roots level, the coating and the surface being coated by the physical and chemical interaction between the degree of fastness, the surface can be painted bare wood can also be painted substrates. The wall paint with weak adhesion is easy to fall off, affecting the appearance of the wall.
4, strong viscosity: refers to the viscosity of the paint, you can use the paint viscosity measurement instrument measurement, viscosity is an important indicator of the performance of the coating, for the storage stability of the coating, construction performance and film performance can have a great impact. If the paint is too thick, it will not be easily painted, but it will be too thin and easy to fall. Therefore, the viscosity of the paint must be controlled within a certain range.
Editor's summary: The purchase notice for wall paint and the classification of wall paint are introduced here, and we hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
