Wallpaper can be pasted on a flat and dry wall. The base surface of wallpaper must be clean and smooth, and the treatment method is to batch putty and then polish it. The standard of polishing is the same as that of preparing to brush latex paint.

Two days before the wallpaper is laid, the wallpaper basement membrane or varnish should be painted on the wall (nitrocellulose paint or alkyd paint is enough, there is no need to use polyester paint). Note that some paint spots will splash on the wall when painting the top; When painting the wall, the brush may also bring some hair. After brushing, it is best to simply polish the basement membrane.

Daily cleaning of wallpaper:

1, PVC plastic wallpaper

The surface of PVC wallpaper is mainly PVC resin, and PVC plastic wallpaper is layered. If the indoor temperature difference is large, PVC plastic wallpaper may expand with heat and contract with cold, resulting in warping.

If the PVC plastic wallpaper is curly, you can apply wallpaper glue to the edge, smooth the edge, blow it with a hair dryer for 10 second, press it hard against the edge by hand until it sticks firmly, and then dry it.

2. Foam wallpaper

Foamed wallpaper is soft and thick, with elastic concave-convex or decorative patterns on the surface, such as relief and wood grain. The concave-convex surface of foamed wallpaper is easy to accumulate dust, so it should be cleaned regularly to avoid affecting the appearance. Generally, it should be cleaned once every 3-6 months, and it can be cleaned with a vacuum cleaner or brush dipped in clean water. Be careful not to let water penetrate into the splice.
