Wallpaper: 3 mistakes you should never make when you change it

2) You do not take the time to prepare the wall before installation.

By doing so, you will not save time. Reality is opposite to it, remember to remove the spikes from the wall and fill the holes and cracks with a filler. Then dust and wash your wall well and repaint it if necessary. Indeed, a wall of bright or dark color could appear under the tapestry. It will also be necessary to cut with sandpaper a satin or shiny paint to which the glue may not adhere. The last thing, it is always important to check the porosity and absorption of the wall, because an absorbent wall will help the glue to adhere. To do this, press a damp sponge against the wall and observe the drops. If they sink quickly on the wall, it is not very absorbent and will require an underlay. In addition, it will make it easier to remove when changing the wallpaper. On the contrary, if the drops bead slowly and are absorbed by the wall, the glue should adhere to it without a problem.
