The purchase of wall paints should focus on the actual use of wall paints, such as the quality of wall paints, environmental protection performance, and do not require any deliberate requirements for other functionalities.
1, the date of manufacture is also the key
Inferior wall paint not only has poor environmental performance, but also has poor light perception, obvious graininess, and rough feel. Although high-quality wall lacquer can greatly reduce these problems, if wall lacquer expires, odor will float and the color will change. After wall lacquer and water are mixed, it cannot be completely dissolved in water, which will affect its use.
The shelf life of high-grade wall paint is generally long, but in order to ensure the effectiveness of the wall paint, when purchasing the wall paint, in addition to checking the environmental protection test report, it is also necessary to pay attention to the delivery time and shelf life of the wall paint. In addition, not all expired wall paints cannot be used. If the wall paints are found to have only expired for three or five days when they are used, they can still be used at a watering rate of 30%, that is, for every 10 litres of wall paint, against 3 litres of water. Some high quality wall paints can also water 40%.
Consumers can choose the thickness of the wall paint according to their preferences. After brushing the inferior wall paint, the paint film is relatively thin, and it is difficult to cover the putty and sandpaper marks left when the wall base layer is treated. In general, after the wall paint is applied, the paint film must be smooth, uniform, and free from traces of grass.
2, true and false wall paint "tracked to follow"
Although some inferior wall paints can be confused on the packaging, they can still find loopholes through careful comparison. The barrels of real-world wall paints have bar codes on them, that is, anti-counterfeiting codes. Consumers can use the product-related websites to input barcodes to determine the quality. Fake and shoddy wall lacquer, in general, will be "exposed".
Once the bad wall paint is applied to the wall, it not only affects the appearance of the wall, but also directly affects human health. In particular, hazardous materials contained in wall paints, harmful substances in the inferior wall paints often exceed the standard, causing harm to the human body, such as excessive formaldehyde, can cause eye and throat irritation, cause skin allergies, and even cause asthma, lead, Excessive levels of heavy metals such as chromium and mercury are harmful to the nervous system, cardiovascular disease, and heredity.
Therefore, in the purchase of wall paint, be sure to buy environmentally-friendly wall paint, regular brand of wall paint must have environmental testing report, when buying, should require the business to produce test reports, it is best that the provincial level above the detection department to show the recent (In half a year) National inspection report to check whether the environmental protection data of wall paint meets the national limit index.
3, choose a wall paint light sense of stress
The color of the wall paint on the market is also varied. From the point of view of decorative effect, there are currently wall paints such as matt, matt, light, and semi-gloss. The price will also fluctuate slightly due to the different painting effects. The gap between the cost of artificial paint on the wall paint and the brush is very small. Generally speaking, the gap is about 2 yuan per square meter.
After the matt wall paint was applied, the wall surface had a low light sensation, while the bright wall paint was applied. The wall light was more noticeable. At present, some consumers prefer to choose bright light wall paint with high light sensitivity in order to pursue the brightness of the living room. When the sunlight and light are strong, the light wall paint will produce reflection, which will easily cause discomfort to human vision, matt, dull or semi-glossy. Wall paint is not easy to reflect, more suitable for indoor use.
In addition to the different light sensitivity of the wall paint itself, the difference in the brushing process can also result in different light sensitivity of the wall surface. If the wall paint is unevenly painted and the walls are uneven, the walls may have “shadows†or even “egg patterns†after painting. If a similar problem occurs, sand the wall and sand it evenly.
