partial wallpapers can be pasted by yourself

some walls are hopeless, but you don't want to spend a lot of time painting, so you might as well try to decorate some wallpapers by yourself. Now many building materials supermarkets sell starch glue, paving tools, etc. choose a roll of wallpaper DIY that you like, and the cost is very low

interviewed master Ma, the decorator. He and his wife worked together to build a background wall of nearly 7 square meters, which took about half an hour. Master Ma said that he bought a roll of wallpaper, a bag of imported potato starch glue, a roller brush and a scraper, which cost a total of more than 170 yuan

the specific steps of paving are as follows: first foam the starch glue according to the instructions for standby, and then cut the paper according to the measured wall area (the main attention in cutting is the problem of matching the flowers. The top and bottom, left and right colors of the two adjacent Wallpapers should match, which depends on your own calculation). Master Ma suggested that it is best to buy wallpaper with simpler design and color. It is easy to spend, and the loss is small. You can also leave a few centimeters more at the front and rear ends of the wallpaper, because the skirting line and the edge of the ceiling are not necessarily 100% flat. After the wallpaper is put on the wall, the excess part is cut directly by the wall line with a wallpaper knife, which looks more beautiful. Then use a roller brush to brush glue on the wall and the back of the wallpaper, and let it stand for a while (the specific time is according to the instructions of starch glue). Then it's time to go to the wall, stick wallpaper and scrape down with a scraper to drive away the air. If there are bubbles, puncture and scrape with a needle. Finally, cut the excess corners with a wallpaper knife. After closing the doors and windows for about 12 hours, the wallpaper will be firmly on the wall. Master Ma's wallpaper has been pasted for more than a year, and so far there is no sign of edge warping or falling off

found that self-adhesive wallpapers are sold on the market, which are simpler to lay and cheaper. Owners with partial decoration can have a try

tips: before you do it yourself, you should know the situation of the wall. Cover the wet towel on the wall. Wetherspoons, a major British bar chain, has also stopped using plastic straws for one time for more than a dozen minutes, and then gently rub the wall with your hand. If the paint doesn't fall off, you can paste the wallpaper directly; Otherwise, it means that the wall has begun to be powdered. Then you need to find a professional team to manage the wall before pasting wallpaper. If the wall is damp and moldy, we should first solve the root cause of the damp, then shovel off the old wall putty and redo it, and then paste the wallpaper to avoid moldy and warped edges

decontamination and cleaning of the wall need to be done properly

there are many stains on the wall, so it's not cost-effective to directly paste wallpaper and paint, so let's clean it. Insiders said that in order to remove the daily accumulated stains, we must first use the right method, otherwise it may cause the wall paint to fade or even "dirty and dirty until the sample has a penetrating crack"

first of all, the wall surface of the home should be regularly cleaned of dust, which can be cleaned with a feather duster. For general wall paint, erasers are very effective for pencil printing and transparent offset printing (if the wall is seriously dusty, there will be obvious color differences in the rubbed places); As for other stains, you can wipe them with a clean rag first (it is best to determine whether the rag fades first), and be careful not to add detergent. If it still fails, wipe it with a rag dipped in a small amount of toothpaste. Generally, stains will disappear. However, if this trick fails, it means that the stain has penetrated into the wall and needs to be repaired. The specific method is to polish the stain with sandpaper to increase the adhesion between new and old paint, and then paint it for coverage. However, remind the owner that it is best to retain some of the remaining wall paint during decoration for future repair of the wall. If you buy new paint, even if it is the same brand, the color will be greatly different from the original paint

as for the black mountain formed after heating, you can only repaint it if you want to completely remove it. I have personally tried to remove it with toothpaste. Although it is also effective, it will still leave scrubbing marks. The owners of construction type dissent will lay wallpaper on the back of the heater or cover the upper part of the heater when heating. This can be more effective. It is a widely used plastic packaging material such as carbonated drinks, beer, edible oil, etc; Electrical materials; Ground prevention. In addition, shoe prints, shoe polish, etc. often appear on the wall where you enter the door to change shoes. Here, you can cover it properly or lay some wallpaper to prevent it
