Is it possible to glue wallpaper on the water-based paint and how to do it correctly?

After buying an apartment from the new owners, the first thing arises is the desire to refresh, make repairs in your new home. It is a costly and very troublesome business, but it is simply impossible to avoid or postpone it sometimes. Often, the taste preferences of former owners are not at all in touch with the perception of the home comfort of new owners. And even more often the reason for this is the quick and cheap cleaning of the square meters by the former owners before the sale. At such moments, few people are puzzled by the gluing of expensive and high-quality wallpapers, where it is easier and cheaper to simply paint the walls.

In the process of preparing yourself for the upcoming repair, a lot of questions arise, and the most frequent of them is whether it is possible to glue wallpapers on water-based paint. If you seek help from craftsmen, then you will not get an unambiguous answer. Some masters recommend removing this cover clean, but others advise not to bother and just cover the walls with a primer. So which of them is right? Today we will understand all the subtleties of gluing different types of wallpaper on the painted surface and answer the question: "Is it possible to glue wallpapers on water-based paint, yes or no?"

Define coverage

Water-emulsion compounds are not so simple, as it seems at first glance, their composition can differ significantly. In order to find out whether the paint can stay on the surface of the walls under the weight of the wallpaper, you need to determine the presence and amount of film-forming substances in it. These are polyvinyl acetates and acrylates, which are part of the adhesives, they are responsible for the coupling of the coloring composition to the surface. If there were enough of them, then the coating should be strong, and gluing the wallpaper on it after a certain processing is completely acceptable. Often these are expensive and high-quality paints, but cheap can not boast of it.

Paint quality

How to determine whether it is possible to glue wallpaper on the water-based paint, gotten from the previous owners? To do this, you need to conduct a small test.

Inspect the walls carefully. If there is a cracking, peeling and shedding of the paint, then its quality is most likely not the best. Alas, but from it it is necessary to get rid.

If the paint is adhered to the wall flawlessly, it is worth checking how it behaves under a layer of paper. Use a piece of unnecessary wallpaper or newspaper. Pour a small area and after completely drying try to tear off the paper. If it easily lags behind the wall along with the water-emulsion, then you can not glue the wallpaper on such a cover. If it keeps firmly, only the paper layer is removed, and the paint is held on the wall - you are lucky, you can glue wallpaper on top of such a paint.

Choose wallpaper

You can not paste wallpaper on water-based paint. They differ in the quality and thickness of the material, and therefore the time for the glue to dry under them will be different. The longer the glue will remain moist, the greater the chance of soaking and peeling the water-based emulsion together with the wallpaper.

• Ordinary, thin paper (cheap) wallpaper can be glued, they are light and the glue will dry quickly.
• Flizeline wallpaper on water-based paint can be glued after a certain preparation, their structure allows the glue to dry quickly.
• Washable wallpaper or any other thick is better not to choose. They are heavy and will dry for a long time, so the risk of peeling is very high.
• The best option - a liquid wallpaper. On water-based paint, they are applied well, will be well retained, and even hide the unevenness of the walls.

If the paint is unreliable

If the paint on your walls does not pass the test, you need to get rid of it. The surface should be thoroughly cleaned with water-based emulsion.

When the paint layer is thin, it can simply be washed off with water. The process will take time, but there is nothing complicated in it. You will need a bucket of hot water, a detergent and a cloth. Flush the paint carefully so that even small particles do not remain on the surface. In the water, add a little detergent and wash the walls with this solution. Try to change the water as often as possible, your task is to wash off the paint, and not smudge the wall. After washing, the surfaces should dry completely, and only after that you can continue working with them.

If the layer is thick, then a spatula can not be avoided. They need to remove the water emulsion as much as possible, and then wash off the residues with hot water and soap.

There is another option: to paste unnecessary wallpaper, cheap or even plain paper, to a painted wall. After the adhesive dries completely, they are removed, and with them, water-based paint.

If the paint is strong

It is important that the adhesive composition penetrates as deeply as possible into the paint and thus provides the best bundle. If your walls are perfectly smooth, then you need to walk on them with rough sandpaper. Roughness will provide better absorbency.

Primer

Now go to the next step - primer. Compositions today are sold a lot, give preference to those who have high adhesion properties. With this composition, the walls are covered in several layers with an interval of 1-2 hours, you can use brushes or a roller. Each layer should dry well before subsequent application.

In the primer contains a solvent that helps it penetrate into the deep layers of the paint and thereby increases the strength of the joint. Sites on which the paint does not hold well must be cleaned. These places should be puttied and dried well.

After the walls have been carefully prepared, you can proceed to further repair stages.
