Where to start repair

Any work begins with a preparation process. You need to purchase the material itself and related products, tools and accessories.

We have talked about the rules for choosing wallpaper on the pages of our site more than once.

From the tools you will need:

  • a mandrel for attaching an abrasive or a grinding block;
  • abrasive material;
  • sanding sponges for hard-to-reach areas.

You can use a sanding mesh as an abrasive material, but it is cheaper to use sandpaper. The quality of work will not suffer from this.

The use of a sanding mesh makes work more comfortable, since the mesh is not clogged with debris and dust during operation. But the correct paper also gives very good results. In addition, it is much cheaper than mesh.


The abrasive is marked on the back. Numbers 80 … 200 characterize the coarse-grained structure of the abrasive, and numbers 250 … 2500 indicate the fine-grained structure of the emery material.

Sanding pads are available with cut corners for easy handling of hard-to-reach areas.

Of the accessories you will need:

  • stepladder or sturdy table;
  • spotlight or lighting fixture;
  • spatulas;
  • rule or level.

A drywall surface requires a finishing putty and priming.

A more time-consuming process awaits you if you are going to re-glue the wallpaper or stick it on a painted or wooden surface.

Everything in order

Any surface is freed from the old coating, dried and primed. If the surface is very uneven, it is plastered.

After drying for a day, the surface is again primed. The primer is applied after each layer of plaster or putty.

Rule 1

To obtain a high quality surface that can last tens of years, be sure to use all consumables from the same manufacturer.

If you bought plaster from a certain manufacturer, then the putty and primer should preferably be from this manufacturer.

Once again about deleting old wallpaper

You can use different methods to remove old wallpaper.

The simplest and most reliable way is to moisten the surface with a warm detergent solution. The solution is applied to the wallpaper with a sponge, roller, sprayers. With a pause of 15 minutes, you can carefully remove the lagging and swollen wallpaper with a spatula.

This method is good for removing thin paper wallpapers.

Do not forget that you cannot remove multi-layered wallpaper in this way. They are removed by using a steam generator or by ironing them with a hot iron through a damp cloth.

Multilayer wallpaper includes non-woven, vinyl, washable wallpaper, since it has a top protective layer that prevents water from entering the surface.

The most important thing

To obtain a high-quality surface for gluing wallpaper, it is necessary to carry out finishing grinding.

To prepare the walls for wallpapering, perform the basic operations:

  1. Install the correct side lighting. The light source must remain in one place throughout the entire work.
  2. Sand the walls from top to bottom with a circular motion of the tool.
  3. Treat strips no wider than 1 meter. After going down the strip to the very bottom, sand the next strip of the same width.
  4. Control the surface for light with a level or rule applied to the surface to be treated.

Never try to sand pits or depressions. You will only spoil the surface. Better putty the detected defect. With subsequent surface cleaning

When preparing walls for wallpaper, small scratches are allowed on the sanded surface.


A few words about the mechanization of the process

The use of mechanical devices is advisable when removing old paint, plaster, rough sanding.

At the finishing stage, it is best for a beginner to use hand tools. It is both more reliable and cheaper, albeit longer in time. For more advanced builders, we recommend using eccentric or orbital sanders.
