It's not just expensive labor. People's walls are better painted and the paint is more environmentally friendly, so they can do whatever they like.
Foreigners always like to upload some videos of their own house renovation. The most colorful one is to paint the wall by themselves, change the color of the wall, and make some small changes to the wall. If we want to change the color of the wall in a few years after the decoration, can we do the same?
The answer is yes, of course, but we need to solve some practical problems that we need to face at home according to our national conditions. After reading this article, you can get:
What kind of paint can be brushed to remember that you don't need to move the whole family to avoid smell after brushing?
How to restore and change the color of different damaged walls?
Apart from the VOC in the paint, what is the APEO in the color paste?
NO.01
To grade the difficulty of wall painting, which level can be painted by yourself?
In European and American apartments, plasterboard is often pasted on the wall, which saves many steps of wall treatment, so it is easy to brush the wall. In China, only when the trunk line process is applied on the rough wall surface, can the painting be started until it is restored to an extremely flat level. Therefore, our construction period is longer and depends more on the craftsmanship of the workers. The materials and labor for the five processes are not as expensive as plasterboard for the whole house
The cheapest and most suitable wall surface for DIY painting should be intact without cracks or hollows. After sanding once, you can brush two finishing coats.
NO.01-1
There's something wrong with the wall. Please shovel the wall
After a long time on the wall, there will be various problems, such as peeling, hollowing, cracks, mildew and so on. When encountering these problems, we can't simply cover them by painting, but we need to do "surgery" on the wall.
The complexity of "operation" depends on the damage degree of the wall surface. It is decided whether to shovel the putty, to the cement mortar layer, or to the wall base with concrete and red brick leaking out.
In the above three cases, respectively, the standard renewal (removing putty), depth renewal (shovel to plastering layer) and extreme renewal (shovel to base layer) in the assembly model product system are corresponding.
Is there a wall without "surgery"?
Yes, the intact wall can be painted directly by sandpaper polishing.
No.01-2 dark color to light color, cement wall to color, also shovel the wall skin
Take white as an example. Generally, there are four or five grids for each color system of color card from light color to dark color. White paint can only cover the lightest grid. Some brands have good coating coverage, but how deep can they cover? You need to consult the manufacturer or dealer.
▲ take white as an example, only the first grid can be covered,
Other colors don't hold.
Dark wall wants to change light color, cannot cover how to do? Then we can only ask the worker's master to shovel to the putty layer and re apply the putty and paint.
No.01-3 the wall is intact. Try it yourself?
The painting of intact wall is much simpler than that of damaged wall. If you polish it with sandpaper once to increase the adhesion, you can directly paint with roller.
The one who consumes the most physical energy,
It should be sanding before painting.
The walls are well preserved, but in case of mildew, it is necessary to use some cleaning agents to remove the mildew on the walls, clean the mildew, and brush the primer and two finishing coats after drying thoroughly.
However, wall painting is still a physical work. If you want to change the color in a large area, you'd better ask the worker's master.
Make small changes on your own.
Great changes, workers.
No.02 what kind of paint can be applied immediately?
Europe and the United States are relatively strict in the environmental protection identification of coatings, so people can brush at ease. At present, many paints with a series of environmental protection standards can be bought in China. As long as there are corresponding environmental protection standards, it doesn't matter where the paint is produced.
Environmental protection standard of no.02-1 coating
Just look at a few
There are two kinds of VOC detection methods for coating, i.e. VOC content in the tank or VOC release in the air after the paint is brushed on the wall.
China's ten ring certification, German blue angel certification and European flower certification test the VOC content in the tank; Finland M1, France a +, IAC and other standards test the VOC release in the air after painting the wall.
Among the well-known imported paint brands on the market, the brands that adopt the VOC content detection method in the tank are: Dufang adopts the German blue angel certification, libon and Dulux have the green guard certification, and Frege has the EU flower certification.
Among the brands that adopt the method of VOC emission detection in the air, Finland's local M1 certification is used by Finn and France's a + certification is used by Dulux.
There are many product lines of each brand, some of which may be certified, some of which are not. When purchasing, the certification on the coating package shall prevail.
Paint, especially what you remember to brush, according to these standards, it's almost the same. It doesn't matter whether it's imported or not.
NO.02-2
Do you want APEO free?
For most consumers, color paste mainly depends on the accuracy of color mixing. Careful consumers may notice that some color pastes will also play the environmental protection card and have a small APEO free logo. Is this detail important?
There are many stories behind APEO, and European and American markets have very different attitudes towards it.
APEO is a kind of surfactant and environmental hormone. It is widely used in washing and textile printing and dyeing. Compared with other surfactants of the same type, the natural metabolites of APEO discharged into rivers are very toxic to fish.
The EPA has tested the concentrations in 30 rivers that meet various test conditions. It is found that the concentration of the metabolites of APEO is far from the level of causing biological poisoning, so it is judged as safe, so it is still in normal use up to now.
Europeans believe that APEO remains in the water and will gather in the body of fish, while humans eat fish, emmm It's too dangerous. It's better to limit this thing before human beings suffer from APEO. So many European paint brands' pastes have been treated with APEO free.
The fear of human abuse of environmental hormones,
It began as an American writer,
Rachel Carson's silent spring.
In the domestic market, there are no standards and restrictions for APEO. But you don't have to worry too much, because APEO can only enter the human body through the food chain. If you use APEO free products, very good, at least you can reduce the environmental hormones in the food chain.
If not, there are many ways to reduce the probability of environmental hormones disorderly entering the food chain, such as using less disposable tableware, using less indoor pesticides, avoiding the use of over packaged products and so on. These environmental protection measures are also immediate.
What color is No.03 suitable for home?
When decorating at the beginning, I found that the color of the brush was not suitable for my home after living for several years. It didn't match with the furniture and skirting line. What color would I choose if I changed it again?
The big white wall painted in the past few years, now I find that there can be more changes at home. What changes can be made to the wall?
No.03-1 corridor and bedroom with poor lighting,
It's better to change the color wall back to the white wall
I always feel that I can't support the popular color.
For example, all the bedrooms are blue, the living room and dining room are gray. After living for some time, we will find that the lighting of this place is not very good all the time, and the wall color looks dark.
So don't hesitate to change back to white. It's not unreasonable for so many people to use white.
The typical dark corridor without windows is still suitable for the wall with white tone.
Or the children's room, in the decoration of the time too hard, the children themselves can not see those childish colors. It's better to directly change back to white, give the baby a space to think calmly.
No.03-2 is not a wall color easy to see,
It's because it doesn't match the furniture.
Sometimes feel the effect of the living room is not good enough, often is the order of the decoration problem.
Ordinary people decorate the steps is to collect a lot of good-looking pictures on the Internet, and then choose a picture on the effect of looking at a particularly good color to paint the wall.
But when buying furniture, there is no purchase according to the effect of picture guidance, so the overall effect will deviate a lot.
▲ take these two pictures for example, from the wall, furniture, floor, curtain to lamps and lanterns, they are all colors with yellow in the gray and gray in the white, which are controlled very precisely. If the wall is painted with gray that is blue or black, or the color saturation of the sofa is too high, the effect will be greatly reduced.
At this time, you can measure the cost performance. If the wall area is small or the furniture is too expensive, it is more cost-effective to change the wall color, otherwise, it is more cost-effective to change the furniture.
Taking the home of a designer and home blogger as an example, she changed the floor and part of the wall surface into a very bold dark color after moving. She thought that the retro leather sofa that she loved for many years would match the new home very well, and it would not match at all.
So she pointed out that the cost of changing the dark wall into the white wall was too high, or it was convenient to change the furniture. Anyway, she was a designer and had a lot of resources. Finally, she changed to the fashionable family in after.
