First, clean the walls. Before cleaning, clean the dust and sundries on the wall with a vacuum cleaner, and then clean them with clean water. The wall should be coated with a layer of mildew inhibitor, and construction can only be carried out after it is completely dry.
Secondly, deal with the wall coating. The purpose is to enhance the adhesion and smoothness of the wall. Before treatment, it should be polished with sandpaper and then cleaned with wire brush. It is best to use sponge roller for wall paint, so that the surface is more uniform.
Third, patching and painting. Before wallpaper is laid, cracks and unevenness on the wall need to be repaired. The choice of caulking materials should be of good quality and durable. After the caulking material is dried, grind it with sandpaper until the surface is smooth.
Fourth, put up wallpaper. Leave a margin of 5- 10cm horizontal and 3cm vertical for the wallpaper as required. Spread the whole wallpaper on the desktop and wet the glue to make the paper spread easily. After the glue is dry, stick it on the dry and tidy wall, and then flatten and compact it from the middle to the outside in turn.
Finally, deal with the background and decoration. Cut the edge of the paper with a tool and cut off the wallpaper in the background according to the drawing. Finally, the wall is more beautiful by using proper wrapping and sealing.
In short, the correct wall treatment method is very important. Carefully following the precautions can make the tooling wallpaper more stereoscopic, beautiful and environmentally friendly.
