I am going to introduce them briefly in this article. To get started with, you should check (if you have not already done it) what is the state of the wall. If that wall is uneven or cracked, the paint is not going to manage to hide these shortcomings. In consequence, the paint on the wall would look just badly. Choosing thick wallpaper (more on this site) would be much better and more effective solution in this case. Secondly, you should keep in mind the future revision of the design. Changing the color of paint is simpler to do. In the case of better paint, you wouldn’t even need to wipe the old color – it is enough to paint wall with the new one. Thus, if you plan to change color of the walls often, painting can be more comfortable for you. You should also ask yourself, what kind of pattern you want to have on your wall. If you are interested in simple colors or repetitive patterns, then you can use either paint or wallpaper – http://www.demural.co.uk/photo-wallpapers/world-maps (http://www.demural.co.uk/photo-wallpapers/world-maps). If you prefer to have on the wall a picture with a big, complex pattern, the wallpaper would be more useful. If you are real traveler, possibly you would enjoy map mural.
If your son is a football fan, he would absolutely like to receive stadium wallpaper. Nevertheless, the official living room will probably look better with simple colour. Another necessary factor is price of paint and wallpaper. Nevertheless, in that case it is almost impossible to generalize, since prices vary and significantly depend on the particular kind of wallpaper or paint. The simplest option for checking this is to compare different products from a price range that you are interested in. To sum up, the decision between paint and wallpaper hugely depends on the quality of your walls, your preferences, the type of space as well as on the financial resources you plan to spend on this.
