First you need to prepare the wall surface for wallpapering. Remove the old coating with a spatula, wetting the wall if necessary. Then it is necessary to thoroughly putty all the pits and dents - the surface must be perfectly smooth, so that the result really makes you happy.
Glue sheet by sheet to the wall, joining the grooves together. Please note that these are not rolls of wallpaper, but smaller elements - this means that if one sheet is glued crookedly, then the entire coating will be curved. When the entire wall is covered with decorative sheets with special patterns, you can proceed to the next step.
Now begin to separate the material that will open the patterns cut out on the sheets. If you stuck everything evenly, then the patterns will turn out to be neat and beautiful. Such work needs to be done across the wall.
You can not peel off all the strips, but leave part of them so that the overall pattern looks more original. Remove all debris that has appeared after such work and arrange furniture. Agree that such wallpapers will look very original in any room. Are you ready to experiment with this result?
