How to glue wallpaper on old paper wallpaper. Is it possible to glue new wallpaper on the old canvas? What to do with liquid wallpaper

Wall wallpapers are widely used in our country and are the most commonly used wall coverings. Everyone at least once in their life was engaged in wallpapering and it seems that there are no difficulties. For some, this process is a creative pastime, during which you can have a pleasant conversation with a partner (at least two people glue the wallpaper). For some, wallpapering is a real torment, because it is necessary to remove the previous wallpaper, clean the walls, choose the right texture and pattern, stick it evenly and accurately - a rather long and tedious process. When preparing a surface for wallpapering, many people ask themselves the question: is it possible to glue wallpaper on old wallpaper?

Advantages and disadvantages

In order for the wallpaper to lie qualitatively on the surface of the walls, to hold for a long time and so that swelling does not begin to form on their surface over time, it is necessary to carefully prepare the working surface: you need to remove a layer of old wallpaper, if necessary, level the problem areas with a primer or putty, dry thoroughly and degrease. But if there is no way to remove the old wallpaper, or there is simply no desire to do it, then many will begin to glue new wallpapers on the old ones. What can happen in such cases? There are two options for the development of events - the wallpaper will either hold or not. But even sticking on an old layer of wallpaper has some advantages:

• If the previous layer of wallpaper is thin enough (these are not heavy vinyl or non-woven wallpapers) and firmly attached to the wall, then you can glue it directly on them - the new wallpaper will last long enough and there will be no problems.
• If, after removing the old layer of wallpaper on the wall, bumps and roughness are found that will be visible on the new wallpaper, and there is no way to eliminate them, then you can apply new wallpaper to the old one - the layer will create the appearance of a flat surface. In addition, the adhesive properties of old wallpaper are higher than that of an unprepared wall - the wallpaper will lie on the surface faster and fix better.
• Sticking new wallpaper on the old one will significantly save time and money that had to be spent on surface preparation.

But, despite several positive properties, the disadvantages of this method are much greater. Often such a nuisance occurs: the new wallpaper is already pasted, and the old wallpaper under them begins to peel off. And one fine day, you can find that both layers have practically peeled off. There is also a high probability of bubbles appearing under the wallpaper. Even if people tried very hard and carefully removed the air from under the wallpaper during gluing, the wet surface of the old wallpaper can begin to warp and affect the top new layer, which causes the appearance of a large number of bubbles. These air bubbles cannot be removed after the wallpaper has dried. The only rational way out in this case is to re-repair. Miser pays twice.

How to remove old wallpaper

Removing old wallpaper from walls is not that difficult if you use the right techniques and methods.

• To make old wallpaper easier to remove from the wall, you must first wet it. Previously, water was used for this, but at the moment there are special tools - Quelyd Dissoucol, Atlas Alpan and others. These products are absolutely harmless to humans, do not cause negative reactions and are environmentally friendly. The method of application is indicated on the package.
• If it is not possible to purchase special products, then you can use dishwashing detergent, which is diluted in hot water. This method is very effective for preparing wallpaper for removal.
• Remover is applied to the wallpaper with a spray gun, brush, or roller.
• After applying the liquid to the wall surface, you must wait 15-20 minutes so that the wallpaper is evenly and thoroughly saturated, and only after that you can try to remove it.
• In places where it is especially difficult to remove old wallpaper, you can use an electric steamer. Due to the small working surface, it has a low productivity, but it can easily cope with small areas of firmly glued wallpaper.
• When new wallpaper is glued, it is necessary to use special glue, but not PVA or other adhesives, because in a couple of years you will have to do the most difficult job of removing wallpaper.

The question “Is it possible to glue wallpaper on wallpaper” is asked quite often and this is understandable - people want to save their time and effort. In order to tear off old wallpaper, you need to apply, sometimes as much force as for pasting them. Sometimes you can spend a whole day or more to tear off old wallpaper and oh, how you don’t want to do it. Let's see what the desire to save in this way will lead to.

Professionals unequivocally state that the most important thing is to initially properly prepare the walls for wallpapering - this is not even half, but most of the success. But you really want to do everything faster. It is absolutely unknown who came up with the idea of ​​​​not removing the old wallpaper and immediately sticking a new layer on top of them, but it is obvious that he was a very lazy person.

Those who were engaged in repairs in an old apartment, it was not uncommon to see a whole sandwich up to a centimeter thick covering all the walls. It is very difficult to deal with such disgrace - it usually turns out that the walls are not prepared at all and you have to start everything from the beginning. At this moment, I want to swear at entire generations of home craftsmen who left behind such a legacy. Although, maybe they had no other choice and they are not to blame for anything.

It is human laziness that makes people ask the question again and again: “Is it possible to glue the wallpaper right on top?”

It is impossible to answer this question unambiguously. Let's figure out what are the pros and cons of sticking wallpaper on wallpaper.

The advantages include:

• Significant savings in time and effort. Sometimes it is possible to reduce the duration of work by 2 times. True, if you make a mistake, then not only the repair time but also its cost will double, this option is quite likely.
• No surface preparation costs. The bottom layer of wallpaper levels the wall and it will not need to be primed. No wonder in the old days newspapers were first glued to the walls. But keep in mind that newspapers are newspapers, and wallpaper is a completely different matter. And in those days there were no such means that made it possible to level the walls quickly and efficiently. Again, in case of failure, the cost of repairs, on the contrary, will increase significantly.
• If the bottom wallpaper is smooth and papery, then the top layer sticks very well and for a long time. If this is your option, you can try, just remember that stains of grease or paint can ruin all your plans, be sure to check this before you start.
• It will be ideal if separating wallpaper has been pasted before. Their top layer is easily separated from the bottom, which remains on the wall and serves as an ideal basis for a new one, but very few can be so lucky and it is better not to count on such an option.

This is where the pros end and the cons begin:

• Nothing can be pasted on vinyl and embossed wallpapers. Vinyl does not absorb glue and the relief reduces the area of ​​​​the connection and, accordingly, the strength of gluing. If your wallpaper is vinyl, leave the idea of ​​sticking it on top, the same can be said about embossed wallpaper - rip it off without pity and don't experiment, spending your time and money on it.
• If the first layer of wallpaper is not firmly attached to the wall, you will get (at best) ugly bubbles and at worst everything will just fall off the walls. It is quite difficult to check - there can always be some kind of surprise and everything will go wrong. If you are not sure, play it safe - so you will be calm for the future result.
• On top of dark and contrasting old wallpapers, you should not stick light ones.- the pattern will shine through and you will have to re-glue everything. In this case, there are only two options to get out of the situation - peel off the junk and do it all over again (as we recommend) or buy thick wallpaper with a bright color, preferably not geometric.
• Joints between panels are usually uneven and will protrude through the new layer. If the predecessors glued the wallpaper with an overlap, do not try to glue it from above - nothing good will come of it.
• If the new wallpaper is vinyl, under the second layer the first one will get wet and fall off. The vinyl film does not allow the glue to dry out and the whole sandwich will get wet up to the wall, and then it can easily fall off.
• Old wallpaper has absorbed all the smells over the years and after a fairly short time, you will again have a musty unpleasant smell in your apartment. If you don't believe me, try it, but keep in mind that this warning is not taken from the ceiling, but is based on numerous observations. Smells penetrate through any, even the most dense paper, non-woven wallpaper. How this happens is not clear, but the fact is obvious.

Let's move from theory to practice.

When you can stick new wallpaper on top of the old:

1. You yourself glued the first layer and are sure that you did everything with high quality. In this case, the likelihood of trouble is much less - there will be no unexpected surprises from the predecessors.
2. Old wallpaper was paper or non-woven without vinyl coating and paint. Both paper and interlining are excellent bases, the main thing is that they are initially laid with high quality.
3. The first layer is not embossed. Everything is clear here, it is impossible to paste over a bumpy surface - it will still fall off, or irregularities will be visible the farther, the more
4. The new wallpapers are quite thick and darker or brighter than the first ones. e. Here, too, everything is clear, for example, linkrusta will close any irregularities. Only if you have the money for expensive linkrusta is it worth saving on proper surface preparation.
5. The old wallpaper is completely intact and there are no peeled places.. Any damage will be magnified or visible. Don't experiment with it.
6. In the first layer, all wallpaper joints are firmly glued s. This is one of the most important conditions - the joints are the weakest point and the ingress of moisture peels them off instantly, and if they are already moving away, expect trouble.

When you should not glue new wallpaper on top of the old.

• The first layer is glued loosely. Run your hand along the wall, if periodically there is emptiness at hand, then you will hear a characteristic rustling.
• First coat with vinyl or embossed
• The wallpaper is very old and smells bad
• Part of the wallpaper is peeled off or the joints are peeled off.

How to actually glue.

If you still decide on such an experiment, start by saying that wipe the entire surface of the wall with a slightly damp cloth. Actually this is important. So you will remove a layer of dust, soot, etc. You might be surprised how much good stuff there is. In addition to the strength of gluing, this will also affect the appearance. Less likely to get stains around the seams (dust can mix with wallpaper paste and give this effect).

The next step (especially if the pattern on the first layer is unstable) it is necessary to coat the wallpaper with a solution of glue. This is done in order to fix the paint a little and it does not wear off and does not smear a new layer at the joints. After the glue has dried, you can start gluing. Further action must be done in accordance with the instructions for gluing the appropriate type of wallpaper. We recommend using non-woven wallpaper for this, they will hold better.

We really hope that this information will help you avoid mistakes and save money and time. Whichever option you choose, remember that the best way is to peel off the old wallpaper and do it all over again.

The interior of the room is perfectly complemented by photo wallpapers on various topics. The process of pasting the room with wallpaper does not seem so complicated. But in reality, it is quite difficult to paste wallpaper without the necessary knowledge and experience. If other types of wallpaper do not always require compliance with the docking of the pattern, the photo wallpaper should be equipped with an orientation to this feature.

Wall murals are easily glued to the surface and they are resistant to mechanical stress.

As a rule, after deciding on gluing, the question arises: is it possible to glue photo wallpapers over old wallpapers? The answer is detailed below. In addition, all the nuances associated with this process are described, as well as the rules that must be followed in order to achieve the ideal result.

How to stick photo wallpaper on the wallpaper pasted before?

The most crucial moment is the stage of pre-treatment of the surface of the walls. If there are old wallpapers on the walls, then they need to be torn off. First of all, you should try to carefully remove them from the wall. If they are difficult to peel off, do not rush to tear them into small pieces.

There is an option for sticking photo wallpapers on old wallpapers, but this process is demanding on the following factors:

• the depth of the textured ornament is not more than 0.2-0.3 mm;
• the use of photo wallpaper with the simplest method of pasting;
• the density of the photo wallpaper must be at least 200 g/m 2 ;
• old wallpaper must be moisture resistant and in good condition.

First of all, you need to pay attention to the structural pattern. If its depth does not correspond to the above value, it is better to immediately refuse to stick photo wallpapers. This is due to the fact that such an ornament can easily show through the surface of new wallpaper.

Having previously found out that your old wallpaper fits these parameters, you need to buy a set of photo wallpapers, the characteristics of which meet the above requirements. Otherwise, the photo wallpaper will not be able to last for a long time.

When choosing photo wallpaper, it should be borne in mind that halftones and solid patterns with clearly defined figures, in all likelihood, will not be able to hide the old wallpaper under them. Therefore, you will need to focus on canvases with a small and non-contrasting image in order to minimize the appearance of previous wallpapers. It is recommended to take a closer look at the photo wallpapers depicting the forest and thick grass, the metropolis and numerous lights, orchards.

It is advisable to peel off the old wallpaper, then the photo wallpaper will stick more evenly.

If you are wondering how to stick photo wallpapers on vinyl canvases, you should keep in mind that their structure should be closer to paper. In this case, it is extremely important to choose a high-quality glue, otherwise the photo wallpaper will not adhere well to the surface of the vinyl sheets.

If old or new canvases do not meet the specified requirements, it is recommended to abandon this idea. It is best to try to peel off the old wallpaper, carefully clean the wall and level it. This can be done with hot water or special mixtures that are sold at any hardware store.

What kind of glue is required for gluing photo wallpapers on old canvases?

If the old wallpaper has a paper structure, you should focus on adhesive mixtures that are recommended by photo wallpaper manufacturers. Usually they are indicated on the packaging, since a separate type of glue is provided for each type of canvas. The main types of glue for gluing photo wallpapers:

• heavy (used for textile, non-woven, vinyl and textured fabrics);
• light (usually used only for paper webs).

The mixture must be diluted in strict accordance with the proportions indicated on the set of cloths. If this ratio is not observed, there is a risk of a decrease in adhesion and viscosity of the adhesive solution. As a result, the canvases can not only move away with the passage of time, but also not stick to the surface of old wallpaper.

Marking the wall surface for gluing canvases

An important point before sticking is the marking of the whole image, which is presented on the wallpaper. Depending on this factor, it is possible to determine in which parts of the wall it will be necessary to work on the uniformity of the old canvases so that they do not show through the new one at the end of the process.

Any set of such canvases contains a detailed description of the dimensions. Most often they are indicated in centimeters, so it would be advisable to use a simple tape measure. With its help, it is necessary to measure the distance, which is equal to the height of the entire pattern on the canvas, and mark this point with a pencil. This is required for the center of the image so that it fits correctly on the wall and is fully visible. The same should be done for the width of the canvas. After marking, you need to combine all the points with vertical and horizontal lines. In the future, you will be guided by this markup in order to place the drawing most accurately.

Photowall-paper how to glue correctly today we will analyze in detail. Here the procedure is not complicated, but has its own specifics. How to properly stick photo wallpapers should be disassembled from the very beginning. And it all starts with preparation.

If the preparation is not done correctly, then this will affect not only the durability, but also the appearance. After all, then there will be distortion along the plane. Also below will be offered step-by-step instructions for the work and a video will be given where you can see additional information you need.

A variety of materials for photo wallpapers

The world of photo wallpapers (see) in our time is so huge that when choosing, your eyes run wide! But before you follow them to the store, you need to clearly define for what period of time and in what room they will be used. Everything can be done with your own hands and without outside help, then the price of coverage will not be significant.

• For example, the bedroom, living room and hallway are universal. Photowall-paper from absolutely any material is perfect for them.
• But as for the choice of wallpaper for the children's room, here the most important criterion is the environmental friendliness and safety of the material for the health of the child. The resistance of the material to moisture, steam and high temperatures will be the main requirements for creating a design in a cozy bathroom. And the wallpaper, which is easily and quickly cleaned of all contaminants, will be an excellent choice for a kitchen or dining room.

According to the composition, photo wallpapers are divided into four main types: paper, vinyl, fabric and non-woven.

All types of photo wallpaper can be simplex (single-layer) and duplex (two-layer).

• Sometimes a duplex can include several materials at once, which undoubtedly affects their strength and service life.
• When sticking such wallpaper, special attention should be paid to applying glue. After all, the wallpaper should be sufficiently soaked and only then applied.

Attention: Many people ask whether it is possible to glue photo wallpapers on wallpapers and the answer here is unequivocal, of course not. After all, the previous coating gets wet and wrinkled and this will distort the coating.

How to choose a pattern

It is better to choose a drawing based on the color scheme of all interior items and furniture (see How to choose wallpaper to match the color of furniture: modern ideas). For example, if the room has rather colorful curtains, bright furniture and other textiles, then whether it is a photo wallpaper with a seascape or impenetrable jungle, a night city with quiet streets or a blooming juicy meadow, they will only be an irritant - ripples in the eyes.

How to paste new wallpaper on old

All the pros and cons of sticking new wallpaper on the old

Basically, the masters of the wallpaper business insist on the importance of the process of preparing the wall before gluing.

That is, you need to remove the obsolete layer of wallpaper, remove the remnants of the spent glue, level the surface, treat the wall with a primer, and only then proceed with applying new ones.

If you have a wall in front of you with wallpaper that was pasted using the technology described above, and they have been perfectly preserved to this day, then you can still apply a little trick and paste the wallpaper without removing the old one.

Technology Benefits

1. As a result, the process is greatly simplified.
2. The time and labor input is even incomparable.
3. The economic benefit is also undeniable.

But the disadvantage can be attributed

Comparing the positive and negative points, we can conclude that such an experiment is quite risky and it is better not to apply it to expensive wallpapers.

Attention! The method is not applicable to wallpapers of the type: non-woven, vinyl, and wallpaper with an embossed pattern.

You can only glue wallpaper on a paper basis in this way.

Test for the possibility of sticking new wallpaper on the old

First, check the surface for bubbles. To do this, you just need to run your palm with a little pressure along the entire wall.

If there are unglued cavities on it, you will immediately feel it, and in this case, the idea of ​​​​gluing old wallpaper on new ones will have to be postponed.

If the wall passes the test, then evenly wipe it with a damp sponge. We wait a few hours, and then we look to see if the swelling of the old glue from moisture has occurred. If the result is successful, we move on to the next test.

We apply a couple of layers on a small section of the wall and wait for it to dry. If after a day there are no places of deformation of the base, you can safely get to work.

Wall preparation

The surface is cleaned of dust with a rag or vacuum cleaner. Two coats of primer are applied, which in this case will be a mixture of white acrylic paint. You can add building chalk if the composition lacks density.

Important! Primer coats are applied with a minimum of one hour drying between them.

After the primer has completely dried, the surface is sanded.

Adhesion strength test

Do not immediately paste over all the walls. It is better to try to put on glue one strip in the corners of the room and see what happens tomorrow. If after a day the sheets of wallpaper will firmly adhere to the walls, feel free to proceed to the remaining surface.

Important! Sticking paper wallpaper on vinyl is possible if the covering film is removed from the latter. To do this, the surface pass needle roller and moisturize. After soaking the substrate with a spatula, remove the entire film. As a result, only a paper base remains on the wall.

From the foregoing, it is clear that new wallpaper for the old one is quite acceptable, but it greatly limits the design options for the room, and after all, changing the coating on the walls is done precisely in order to improve the appearance of the room. And here this technology fundamentally cannot satisfy you.

How to quickly and easily remove wallpaper from the walls

If you are in doubt and cannot decide how you feel, opt for the correct and complete technology. So you definitely won't get a pig in a poke. You can also look for a specialized forum and ask craftsmen who have experience in life with such an update. Or watch video reviews.

Performing a high-quality wallpapering process is not so difficult, especially if you know a few secrets for removing the previous layer.

To simplify the work you will need:

The first step is to scratch the old wallpaper. The fact is that modern wallpapers are quite well protected from the effects of moisture on them, and it is possible to simplify their removal only by first thoroughly moistening them.

Therefore, by creating scratches and various damages on the surface of the coating, we allow water to penetrate deep into the material and destroy their structure.

Advice! Don't forget to cover your furniture and floor before wetting the wallpaper. Take care to protect sockets and electrical appliances from moisture.

The solution for destroying the old wallpaper coating can be supplemented with any detergent, even crushed pieces of soap. In addition, there are a huge number of specialized compounds on sale that are directly intended for peeling off a boring coating.

The solution should be applied two to three times at intervals of 15 minutes. As a result, the old wallpaper will come off with a slight movement of the hand and you will not have to scrub hard with a spatula.

If you have a coating in front of you that was not glued to wallpaper glue, then you can remove it only by sanding a dry canvas.
