Using wallpaper is one of the most widely used interior design resources. Despite being designed to last for a long time, it is true that on certain occasions it is necessary to remove it. It may be because of a change of decoration to adapt it to current trends or due to other circumstances such as the transformation of a children's room into a youth room.

When removing wallpaper, it is normal to want to restore the wall to its original condition. The surface must be perfectly smooth to provide a flawless image. This will be necessary whether you choose to paint the room or to put up new wallpaper.

In either case, the wall needs to be smoothed so that it is even and has a quality finish. The idea is to achieve a true surface reset so that no signs are noticeable and it looks brand new. We are going to give you all the keys to achieve this.


It is important to check the state of the wall after removing the wallpaper

Right after removing the wallpaper, you may find yourself faced with several scenarios. The first is that the wallpaper you had installed was designed to be easily peeled off, so much of the work will already be done. Another possibility is that there may be traces of both the wallpaper and the glue you used to stick it down.

In these cases, the first thing to do is to remove everything to clear the wall of all materials. The most homemade option is to use a sponge with warm water and soap. Rub gently to avoid damaging the wall. This will soften the glue and paper, which will be easier to remove.

You can also use other materials such as white vinegar, which can be very useful in these cases. In the market you can find specific products for this task. With the help of a spatula and being very careful, you will be able to remove all those remains without any problems. This is the first step in smoothing the surface after removing the wallpaper.

It is likely that a lot of dust has been generated during the removal, so it is advisable to clean the wall thoroughly. A damp cloth will be enough to trap the particles and prevent them from spreading all over the room. It is very important to make sure that it dries well afterwards to prevent moisture from settling in. 


A good sanding is key to smoothing out a wall

Then you can move on to a mid-range sandpaper such as 180 to finish with a finer 220.

In other words, you should go from less to more in order to achieve a professional finish. Smoothing a wall after removing wallpaper is quite a painstaking and time-consuming job.
