Now there are many walls covered with water-based paint, and people renovating the interior have a natural question - is it possible to glue the wallpaper directly onto this layer. If possible, then how to do it correctly so that the wallpaper does not collapse and slide, the corners do not peel off ... Let's analyze in order all the features of this problematic issue, and find the best solution.
Before deciding how to glue the wallpaper onto the paint, you need to examine the wall and come to a certain conclusion regarding its strength. Information will help - how was the wall painted? - if there is no information on this, then you need to consider the wall itself.
You can determine the type of paint on the wall as follows.
Can wallpaper be pasted over oil and other durable paint?
But with water-based paint, not everything is clear. It can vary in quality.
More often the walls are painted with the cheapest water-based compositions that do not contain hardening binders. These are the so-called polyvinyl acetate or PVA paints. The simplest and cheapest of them, like chalk, are taken on objects easily and easily.
Those that are more expensive contain some polymers, which strengthen their layer, therefore looking more solid. Experts recommend the following.
There are also types of water-based paint with a different base and more expensive.
- acrylic, latex, silicate,
which form a more durable layer. On them, as well as with butter, - you can glue, - scratch, puncture, cover with PVA glue and putty holes, if any.
If you still have not come to an unambiguous conclusion - is it possible to glue wallpaper on the paint, then the wall covering can be tested for the strength of the layer.
Do the same on a small section of the wall as you would on the whole.
A layer of water-based paint, which was recognized as suitable for gluing, still needs to be properly prepared and the bonds between all particles should be maximally strengthened in it.
As a rule, painted walls were previously covered with a layer of plaster and finishing putty. By and large, in this whole design, the main issue is not at all about the paint, which is not difficult to wash off in one working day. And the question is in the reliability of the old plaster and putty layers. If the putty starts to soften and peel off when the paint is washed off, then the work on putting the wall in order will be ten times more. Therefore, together with the examination of the old water-based paint, it is necessary to check the layer of the old plaster. More information -
As you know, before pasting wallpaper, it is required to prepare the surface in order to ensure the necessary adhesion and avoid peeling of the coating. After all, it is the disruption of the working process and insufficiently high-quality preparation that most often serve as the reason that the wallpaper peels off after a short time.
In this review, we will consider whether it is possible to glue wallpaper on water-based paint, and what needs to be done for this.
We note right away that just leaving the paint is a rather risky undertaking. Many masters answer affirmatively to the question of whether it is possible to glue wallpaper on water-based paint, citing the fact that such a base is much better than a coating of oil or alkyd compounds.
And this is correct, but it is impossible to guarantee that the layer will behave stably - the finish can last a dozen years, or it can come off in a year along with the paint. necessary work according to the technology. It will take some time, but the result will be guaranteed reliable and durable.
Of course, it is best if your walls are covered with ordinary paint that is not resistant to moisture, the work is quite simple and should be carried out in the following sequence:
On the picture - different types scrapers, and the choice of a specific option depends on your preferences and volume of work
If your walls are covered with waterproof or washable compounds, then the process will be somewhat more complicated.
But anyway, any person can prepare the foundation with the right approach:
This method appeared relatively recently, but has become very popular among those who carry out repairs due to the simplicity of the process:
There are other methods that are used when preparing the surface with your own hands:
So, we figured out whether it is possible to stick wallpaper on water-based paint. As you can see, it is undesirable to leave the coating, so hold certain jobs you still have to, otherwise after a few months the layer may begin to peel off in whole sheets.
Advice!
Whichever method you choose, remember that before gluing the wallpaper, the walls must be primed, this significantly reduces the absorbency of the base and improves adhesion. wallpaper glue.
A rational solution - in parallel with the repair of the walls. If indoors high humidity, then electrically conductive paint Zinga is perfect, and in other rooms you can use fire-retardant paints for metal Polistil - they not only perfectly protect the metal, but are also completely fireproof.
We examined how wallpaper can be glued to water-based paint, and why the coating should not be left on the wall. If you still have any questions, the video in this article will help you understand some of the features of surface preparation better.
The owner of an apartment often has a desire to radically change the interior. There may be many reasons for this, but in a hardware store there is always something to replace whitewash or old tiles. But sometimes a novice finisher is stopped by the need to somehow decide the fate of the old coating. Do I have to take it off? Not always. We will now talk about whether it is possible to glue wallpaper on water-based paint on the wall.
The answer to the question, it is possible to glue wallpaper on water-based paint, it may turn out to be positive if the surface is sufficiently flat and has no noticeable flaws. But before starting work, it is very important to determine: is there really a water emulsion on your walls?
On oil or acrylic paint Wallpaper is definitely not worth glueing, they adhere very poorly to plaster or putty, while water-based paint holds them well. Therefore, it makes sense to conduct a simple study. It needs some kind of sharp object that can be used to pry off the paint - a spatula or a knife:
Important! Water-based paint is separated from the wall without much effort and in small pieces, or even simply crumbles, and most often - together with the plaster. For the treatment of walls, oil or nitro paints are often used. So they fall off the wall in large pieces or even whole layers.
If you come to the conclusion that you have a water-based emulsion on your walls, you can safely glue the wallpaper. True, not all of them will hold up equally well, so it makes sense to conduct another experiment. To do this, you will need:
A piece of wallpaper can be taken from the same roll you bought to decorate the room. You need quite a bit - even a cut edge is enough for you, but it's better to take a square 10x10 cm:
Important! Water-based dispersion paint has the same properties as water-based paint, so you can also glue wallpaper on it.
Before gluing wallpaper to water-based paint, you need to decide what exactly you want to see on the walls of your apartment. From thin paper wallpaper it is better to give up right away, as well as from not very high-quality vinyl.
You should be interested in wallpapers:
Important! Keep track of all fashion trends in the field finishing works very difficult, especially if you do not do it every day on a professional basis. Therefore, in order not to get confused in the store, we suggest that you study the basic design solutions:
This material dries amazingly quickly, so it is ideal for pasting over water-based paint. Why is it recommended to use non-woven fabrics? They have a wonderful property - they absorb almost all the glue before it penetrates the paint. That is, the water-based layer simply does not have time to fall off.
Non-woven fabric wallpaper is also very a good option... They look rich, while they differ in the same qualities as non-woven ones. Other two-layer canvases are also suitable. But paper base not good, because it dries slowly, as a result - the paint dissolves and leaves.
In essence, this is not really a wallpaper. You do not need to glue them. They adhere perfectly to any surface. If the wall is not perfect, this type of wallpaper works best. Their composition is such that they harden faster than they penetrate the paint layer and begin to dissolve it.
Important! Another advantage of them is that you can even finish an uneven surface, so you definitely won't have much trouble with the wall.
Water-based paint, as a rule, has high adhesion - that is, it provides reliable adhesion to putty or plaster, or to wallpaper. But this does not mean at all that it must be preserved. Nothing prevents you from removing this layer before proceeding with the pasting.
The water emulsion has its own characteristics that must be taken into account before proceeding with pasting:
Important! If the surface is not pre-treated, the wallpaper will lie unevenly, and in addition, it can crack and even tear.
If there are too many cracks and peels on the wall, it is best to remove the layer of water emulsion to the base. This is a rather dirty business, but not particularly difficult. You will need:
Prepared everything you need - start washing. A terry towel is the perfect rag, but in principle, you can use something else:
The process itself is extremely simple. The surface must be heavily wetted, and then washed off with a rag. It is only advisable to change the water as often as possible, and the rag should be thoroughly rinsed.
Important! But what if the plaster started to fall off? After the wall is dry, you will have to patch up the cracks well.
Having decided to leave a layer of paint, carefully examine the wall. It should not have:
Important! If you are lucky and there is no paint on your wall under the wallpaper, it's too early to rejoice, because cracked plaster can cause a lot of trouble, and therefore is of paramount importance.
If you see any of the above, you will have to arm yourself with a piece of coarse sandpaper and put everything in order. Remove any irregularities and then remove dirt and dust. Moreover, this should be done even when the wall looks perfect. If there are no noticeable flaws on it, this does not mean at all that the paint adheres firmly everywhere.
Important! It is best to remove sanding marks with a vacuum cleaner, not with a broom or rag.
No matter how diligent you are with sanding, it is still difficult to make sure that not a single centimeter of the surface is left untreated. There are always gaps. This means that there may be places where the paint does not hold well. Is there a way out? Undoubtedly.
If you gave a positive answer to the question whether it is possible to glue wallpaper on water-based paint, the next step will be
You should not neglect the primer, even if you are going to glue thick wallpaper - two-layer vinyl, non-woven or fabric:
Important! Dry the wall thoroughly before applying the primer.
If you've chosen fabric wallpaper, get ready to tinker with the wall. Such a coating itself is quite heavy, so the wall should be as flat as possible, moreover, to provide good adhesion. Nothing can be done, you have to look for a way out.
There are only two of them:
In both cases, you will need to check how smooth the surface will turn out. For this there is building rule... Its length in this case can range from half a meter to one and a half meters.
Important! If you chose the facing paper option, keep in mind that the seams should not line up with the wallpaper. To avoid overlap, it is better to start gluing the facing layer at half the width.
Despite the fact that this situation can be regarded as critical, it occurs quite often. Previously, the walls were covered with oil paint mainly in non-residential premises:
Important! Removing oil paint is a thankless task. Rubbing the wall with a solvent is unpleasant and will not bring much result. If there is even the slightest opportunity, separate the paint in stripes, and then clean, sand and plaster the wall in the same way as in the case of a water-based emulsion.
Many apartment owners prefer to paint the walls with water-based paint - this is a quick and relatively cheap way of finishing. However, with the next repair and the desire to change something, you have to decide what to do with the previous finish. This is especially true if you are going to change the color of the wallpaper. Let's see if it is possible to glue wallpaper on water-based paint and how best to do it. Let's say right away that this option is acceptable, but with strict adherence to the gluing technology.
In order to properly stick the wallpaper on the water-based paint, it is recommended to make sure that you have correctly identified the type of old paint on the wall before starting work. This is especially true if you purchased an apartment on the secondary market and the previous owners did the repairs. If you stick wallpaper on improperly prepared painted walls, over time this will lead to flaking of the material, the formation of air voids and irregularities.
The composition of the paints can vary significantly, so it is not so easy to determine what the walls are painted with. For internal works most often two types of paints are used - water and oil.
If the walls were painted with oil-based paint, it is characterized by a noticeable chemical odor, high water resistance and the formation of a dense solid layer.
If the walls are painted with water-based paint, such a coating is odorless, has a high penetrating ability, and forms a thin film layer when applied.
To determine the type of paint composition on the wall, it is necessary to remove a small area of the coating with a spatula. If the paint peels off in layers, it is oily, if the composition holds well or is removed in small pieces, it is water-based.
If the paint adheres firmly to the surface, additional testing can be done. It will allow you to determine how the painted walls will behave after gluing.
To do this, a small section of the wall is pasted over with newspapers or old wallpaper. After drying, the material is dismantled. If it can be easily removed along with the paint, in this case it is not recommended to stick to such a coating. If only the paper base is removed and the paint remains on the surface, then it is a water-based paint and wallpapering is allowed.
An important step when deciding to stick wallpaper on a water emulsion is right choice material.
Wallpapers differ in type and thickness, which in turn requires the application of different amounts of glue. If a lot of glue is required and the adhesive dries for a long time, this can lead to swelling and soaking of the water-based paint under the wallpaper.
Surface preparation is an important and crucial stage that will allow you to get a decent result.
Important! You can work only with those surfaces on which the paint layer adheres firmly and does not flake off.
In some cases, paint requires immediate removal:
To carry out the work, it is required to prepare working materials and tools:
The working algorithm includes:
Take a closer look at each step.
The working space is freed from furniture and interior items for free access to the walls. Surface cleaning is carried out with a stiff brush, dust is removed with a vacuum cleaner. The stains on the walls are removed with special solvents.
An examination of the grounds is carried out to detect damaged areas, which are carefully cleaned.
The cleaned surface is checked with a building level in the horizontal and vertical direction. This will allow you to identify differences in planes that need to be eliminated by filling.
All defects and irregularities on the surface are carefully treated with a putty mixture. The putty is applied with a rubber tipped trowel.
After the filler layer has set, the surface is leveled. Medium-grit sandpaper or a fine-grained abrasive mesh is suitable for this job. Thorough sanding of the walls will allow you to get a smooth surface with high adhesive characteristics.
After sanding is completed, the base is cleaned of construction dust vacuum cleaner.
Finally, the prepared surface is carefully primed. Apply the primer with a soft roller or brush, evenly spreading over the entire substrate. Re-processing is carried out only after the previous layer has dried.
After surface preparation, you can prepare for gluing.
For work, you will need the following tools:
First of all, you need to prepare a comfortable workplace where you can lay out rolls, cut strips and prepare glue. Before gluing, the corresponding markings are made on the walls using building level and a pencil. The markings are vertical lines across the width of the finished canvases.
Important! If the wallpaper contains a decorative pattern, print or pattern, the cutting of the canvases is carried out taking into account the joining.
The glue is prepared in accordance with the instructions attached to it in a special container.
To avoid falling wallpaper, during the gluing process and after its completion, you must not open windows and create drafts.
Brief conclusion: wallpaper can be glued to water-based paint, subject to preliminary preparation of the walls. The gluing technology itself is accessible and understandable even for novice craftsmen, so all work can be done independently or with the assistance of an assistant.
If we talk about whether it is possible to glue wallpaper on water-based paint, then it is worth noting that much will depend on the condition of the paintwork and on how long ago it was applied. Pasting a painted surface with wallpaper can really be done, but only if it is of high-quality painting, there are no flaws and any shortcomings.
Important! It is not recommended to glue the wallpaper onto an old painted surface, even if it is in a satisfactory condition. Chances are good that the old coating will not last as long as the new glued canvases.
Not all types of paint can be pasted on wallpaper.
For example, if the coating is made using oil compounds, then you should immediately get rid of them, because they are not different durability.
You can easily determine which paint the surface was painted with.
Usually, two types of composition are used for painting walls:
Important! You can glue wallpaper only on those painted surfaces that are free of defects and are relatively new (for example, the painting took place several years ago, and not several decades ago).
To accurately determine the type of paint and varnish composition, you can take a spatula and scrape off a small part of the coating in the most inconspicuous place.
Removal of the water emulsion is carried out using a soap solution (water + soap). The removal process is quite lengthy, so many people decide to glue the canvases directly onto the paint.
Important! Do not glue canvases on walls painted with oil paint. Such a decision would be a big mistake, because a paint and varnish composition of this type, under the load of the adhesive mixture and the sheets, will simply peel off after a few weeks or months.
Wallpaper on a water-based emulsion can indeed be glued, but this should be preceded by a full-fledged preparatory process.
Many people want to glue the canvases directly onto the paint just because it is very problematic to remove the water-based composition from the wall. The preparation process includes several main stages.
The surface, which is painted with water-based paint, is smooth and even, therefore, it is not suitable for gluing canvases. Roughing is required. This is done with sandpaper or small scrapers.
With their help, you can remove excess paint and varnish composition and create a roughness, thereby improving the adhesive characteristics. The treated surface must be washed with soap and water and allowed to dry naturally.
Important! It is necessary to know the approximate thickness of the previously applied paint and varnish composition. If the paint was applied in several layers and was constantly updated, then gluing wallpaper on such a surface is not worth it. Optimally - no more than 2-3 layers of paint and varnish composition.
Before gluing the wallpaper, you can treat the surface with primers. You need to choose a high-quality primer that will adhere well to the paint and varnish surface and provide good adhesion for gluing wallpaper.
The best option is to purchase a primer with antiseptic properties (it will provide protection against mold and fungal infections).
If the surface on which it is planned to glue the wallpaper has minor chips, cracks and other defects, then they can be removed with a putty solution. If there are serious defects on the surface, then the idea of gluing wallpaper canvases on it should be abandoned (it is better to completely remove the paint and apply a new finish on a clean rough surface).
The application of a plaster composition will allow you to qualitatively level the rough base. And the finished surface will serve as an excellent basis - textile, paper, vinyl, non-woven wallpaper can be glued to it.
Important! You do not need to apply plaster if you intend to glue liquid, textured or other types of heavy and thick wallpaper, which by themselves can hide minor irregularities in the black base.
To do this, a regular piece of newspaper is glued to the painted wall with wallpaper glue, leave it in the glued state for a day, and then tear it off the surface. If the newspaper is difficult to tear off and it adheres well to the base, then there are no obstacles to gluing paper or vinyl wallpaper.
In order to be able to qualitatively wallpaper a wall painted with water-based paint, you will need the following inventory:
Glue application must be done with a brush or roller (depending on the width of the canvases and ease of work).
If it was decided that the canvases can be glued to dispersion or water-based paint, then the work should be carried out in a certain sequence.
If the painted surface, as a whole, is in good condition and suitable for gluing wallpaper on it, but there are several questionable areas, then you just need to get rid of them. If the wallpaper is glued to them, there is a possibility that the stripes will come off over time, because the paint itself will not withstand the weight of the glue and applied canvases.
With caution, you need to look closely at the places where there are traces of swelling and chips. All defects of the rough surface must be removed in advance using a putty or paint and varnish composition.
If the painted base is clean, even and free of flaws, then any kind of lightweight wallpaper can be glued to it.
If the painted base is in an unsatisfactory condition, then it is best to get rid of it right away. This can be done using plain water and soap (you will need to prepare a soap solution). After removing all paint, the walls need to be washed clean water from the tap.
After removing the paint and varnish composition, the rough base should be primed. Before gluing the wallpaper, the base must naturally dry completely.
If the painted surface is in good condition, but the wall itself is uneven, then work will need to be done to level it. Aligning painted walls can be done with a putty.
In difficult cases, a special mesh is applied, which is necessary for adhesion of the solution and preventing the subsequent deformation of the wallpaper.
Important! If the irregularities are minor, then it is best to process them with regular coarse sandpaper. It will not only remove irregularities, but also allow you to create the necessary roughness.
When choosing a primer, it is necessary to clarify its main performance characteristics. The selected primer should work with concrete surfaces and have a light color.
The application of the primer is carried out with a roller or brush, in several layers (each subsequent layer is applied after the previous one has dried).
You can glue the wallpaper on the painted wall after full preparation rough base: leveling, roughing, applying a primer.
The features of the gluing process will largely depend on the type of wallpaper selected. It is recommended to glue lightweight types of canvases on water-based paint: paper, vinyl, textile, non-woven, etc.
The principle of the work is approximately the following:
2. It is recommended to apply the prepared adhesive composition on the wall and on the canvas, treating the entire area of the strip, paying special attention to the edges. Do not apply glue too abundantly - a thin layer will be enough (especially if specialized adhesives are used for vinyl or non-woven wallpaper, with which you can easily glue the canvases even for those who have never done this).
3. Do not allow the adhesive composition to get on the wallpaper pattern. Before gluing the wallpaper to the painted wall, you need to wait a few minutes for the canvas to be saturated with glue.
4. You can start gluing wallpaper from the window or from the most noticeable corner of the room, gradually moving towards the least noticeable areas of the room.
Gluing wallpaper on water-based paint is performed in exactly the same way as on a rough concrete plastered surface.
In the video: Is it possible to glue wallpaper on whitewash.
The main ones are:
You can glue wallpaper on water-based paint. But professional repairmen and builders do not recommend doing this, because gluing the wallpaper on a clean, leveled and properly prepared rough surface is a guarantee that the finish will last as long as possible.
If you glue wallpaper on a painted wall, then they can also last more than one year, but in this case there is a possibility that under the wallpaper, the paint and varnish composition will gradually begin to lose its characteristics and collapse, which ultimately will lead to the wallpaper peeling off the wall.
