During the renovation, when its main part is completed, the moment of finishing comes. Obviously, when applying a new finishing material, you must first remove the old coating. It often happens that the old paint on the walls of the premises has eaten into the surface so strongly over the years that it is not possible to clean it. Then the idea comes to stick wallpaper on the painted walls. Not in all cases it is recommended to do this procedure, but in order to do it correctly, you need to know the basic nuances of the work.

Determining the type of paint

In order to understand whether it is possible to glue wallpaper on painted walls, you first need to find out the type of paint that was previously applied to the wall surface. It is very good if you personally painted the walls, then there will be no difficulties. However, if this information is unknown, you should refer to this verification method:

• Take a damp cloth and run it along the wall, and then observe the result.
• If a small amount of foam appears, as well as if there is paint on the used fabric material, it can be concluded that water-based paint has been used on the surface. This means that you can glue wallpaper on walls painted with water-based paint, but first you need to remove it. This is easy to do: just rinse it off with plenty of warm water.
• It so happens that outdated paint does not lend itself to water, then you need to use a spatula. To do this, take the tool and tuck the cover a little. If the material begins to fall off in pieces, then the walls were painted with oil paint, if on the contrary - the finish falls off in small pieces - then an acrylic compound was used.

After the composition of the old paintwork has been determined, it is necessary to carry out preparations in order to glue the wallpaper on the painted walls.

Also, do not forget about the adhesion of the coating. This criterion is checked by the following method: a piece of building masking tape is glued to the painted surface. With a sharp movement, tearing off the tape, you need to pay attention to its adhesive side: if there are pieces of paint there, then the old coating will need to be removed from the wall. If there is nothing on the tape, then you can safely start preparing the surface for future wallpapering on painted walls.

Preparing a wall with oil paint or enamel

With good adhesion of oil paint and enamel to the base, you can not think about how to glue the wallpaper on the painted walls: in this case, you just need to properly prepare the surface.

1. The wall must be carefully sanded to a matt state. This is done for better material tenacity;

   

2. The surface must be thoroughly washed and dried. In order to stick high-quality wallpaper, painted walls must be thoroughly cleaned of dust;
3. Treating the wall with a primer is also important: it will not only provide improved adhesion, but also prevent mold. This stage is done in two approaches until completely dry;
4. There is a recommendation from the masters: before gluing the wallpaper on the painted walls, add PVA to the wallpaper glue. This will help the material to grip faster and stronger.

Preparation for wallpapering is carried out in the same way as with oil paint. Detail how to putty on paint.

The whole question of how to stick wallpaper on a wall painted with enamel is technologically correct surface preparation.

Surface preparation with acrylic painting

Acrylic paint previously applied to the walls does not imply further sanding of the surface, because it is initially matte. Do not be puzzled by the problem of whether it is possible to glue the wallpaper on painted walls if they already had acrylic paint on them: all that is needed is high-quality preparation for gluing.

1. Rinse the wall surface thoroughly from dirt and dust;
2. Apply a primer in two layers, waiting for the first to dry;
3. Thin the glue strongly and cover the walls with it;
4. When the surface is completely dry, you can start gluing wallpaper.

Preparation of walls with water-based paint

Wall preparation begins by checking the coating to see if paint remains on a wet rag. If the rag is clean, start the process. Before gluing the wallpaper, the walls painted with paint must be primed and dried each layer. A day later, you can already glue the wallpaper.

If it was found that the paint can be removed with a rag, it is necessary to clean the walls from the old coating. If you start gluing wallpaper on walls painted with water-based paint, it will not work to get the desired grip and the new finishing material will simply deteriorate.

The water-based paint material is removed with a spatula and water or using special washes and reagents.

There are other mechanical methods for cleaning paint from walls.

Tips for pasting painted walls

If you decide to glue wallpaper in a lighter tone than the paint that was already on the wall, a problem arises: how to paint the walls before gluing light wallpaper. In this case, the best option would be to cover the wall with white latex paint. Such a mass is rather a kind of primer than paint. It will help the walls adhere well to the wallpaper that you want to stick.

In addition to checking the painted wall for adhesion, it is important that the surface under the wallpaper is flat. If the paint was also applied to an uneven layer of plaster or putty, you will have to redo everything before gluing the wallpaper on the painted walls. Initially, an uneven base will entail a number of problems: the wallpaper will not fit beautifully on the wall and may come off at the joints of the seams. In this case, remove all old paint and level the wall surface.

Each room in an apartment or house should have its own design, so do not neglect the advice received and carefully consider the selection of wallpaper and their sticker. Although the procedure for preparing a painted wall is not a pleasant experience, it is extremely important and the result and the overall appearance of the room will depend on it. Therefore, it will be useful to putty the walls.
