How to glue wallpaper on isolon. Wallpaper backing, which one to choose? How to glue backing paper under wallpaper

Modern wallpaper underlays are designed to solve several problems - level the base, sound and heat insulate the room, and also extend the life of the wallpaper. Non-woven backing for wallpaper, also called repair, construction or painting non-woven, is now used quite often due to its environmental friendliness and durability.

Properties and characteristics of non-woven backing

Non-woven wallpaper is a non-woven, texture-free material with a base of long cellulose fibers. The top layer of the backing consists of polyester fibers. The function of the binding component is performed by acrylic polymer.

Thanks to the combination of all components, an unusually strong and reliable lining material is obtained, resistant to expansion and temperature influences.

Non-woven backing for wallpaper can replace the putty layer. Its uniqueness lies in its masking ability, which allows you to hide small irregularities or cracks.

It is worth noting that the material, like construction fiberglass web, reinforces microcracks. However, non-woven fabric is more elastic than gossamer, but this does not prevent it from maintaining its shape even with constant humidity.

Visually, the repair non-woven fabric resembles an ordinary Whatman paper. It is distinguished by a softer and more uniform structure.

Depending on the type of coating, construction interlining is distinguished:

1. With non-woven covering;
2. With fiberglass covering.

Non-woven backing for wallpaper costs from 900 to 10,000 rubles, has a width of 1.06 m, and the length can reach 25 and even 50 m.

This price range depends, firstly, on the length of the substrate, and, secondly, more expensive samples are covered with heavy-duty fiberglass, which increases the strength and density of the lining. Density indicators range from 160 g/m2.

It is impossible to argue with the fact that wallpaper is the most common type of material for decorating walls in apartments. But wallpaper is responsible for the appearance of the room and its design, and in order to make the room even warmer, a material such as a wallpaper backing is often used. Is it necessary? Let's try to figure it out.

Purpose

The day before pasting the walls, you need to cut the material into pieces according to the size of the walls, let it rest and level out. Smooth sheets should be coated with glue on the inside and allowed to stand for five to ten minutes. Glue is used for gluing polystyrene or heavy wallpaper. The process of gluing the backing is similar to wallpapering. The same technology, only the sheets must be glued end to end.

Removing air bubbles from under the surface is done with a rubber roller. The seams must be sealed with paper tape or narrow paper tape. The next step is to wallpaper the walls, but you need to let the backing dry for at least 1-2 days.

The practicality of the substrate lies in the fact that it does not change its properties for twenty years (some manufacturers guarantee fifty years). This allows the underlay to be used for multiple repairs. This insulating material will protect rooms from the effects of fungus and condensation for several decades, will increase soundproofing and heat transfer, and this will be especially noticeable in those rooms whose walls face the street or common corridors. In addition to all that has been said, the substrate also acts as a leveling material for uneven walls.

How to glue correctly

When gluing with a thick backing, use glue designed for heavy wallpaper. The underlay is used to insulate walls. It insulates concrete walls especially well, which do not have good thermal insulation, and adheres well to almost all building materials (plasterboard, wood, plywood, concrete), as many buyers say in their reviews.

Like wallpaper, the backing is sold in rolls fourteen meters long and half a meter wide.

Benefits of use

It is worth knowing some features of the use of the substrate and its advantages:

• Do not use the underlay in rooms with high humidity (bathroom, bathhouse).
• If there is already fungus on the walls, then you should not glue the substrate on it; first, ensure the complete destruction of fungal formations mechanically or with chemicals.
• Any gaps that appear between the sheets of backing can be sealed with paper strips adjusted to the size of the gap and PVA glue.
• Wallpaper underlay is not an ideal panacea for noise; there are more effective materials for sound insulation, but their installation requires special fastening, and they have a thickness of three to fifteen centimeters. This is where the substrate wins: it is an inexpensive material, easily sticks to the walls, and the work can be done by an unskilled person.
• Thanks to the materials used in the backing, it is easy to cut and the paper backing is easy to glue.
• The material is odorless, does not emit dust into the air, is environmentally friendly, can be used in children's rooms, and is absolutely harmless to human health.
• The ability to increase thermal insulation in places where the walls have low heat-insulating properties: dachas, block houses.

Ecohit is one of the common options

With the development of energy-saving technologies, the use of this material allows saving heat, although not in large quantities. In any case, savings are felt throughout the heating season.

A paper backing for wallpaper can make your walls look perfect by hiding minor defects (we plaster large ones), protect the wallpaper from stains and greatly improve the adhesion of the finishing material to the wall, and contribute to better sound and heat insulation of the room.

The thickness of the paper, as a rule, is much thinner than the thickness of the wallpaper, so it sticks to any surface easier and more reliably. Previously, newspapers were used as a paper backing; today, in construction and finishing materials stores you can successfully purchase paper backing in rolls made from ordinary waste paper.

Manufacturers

The online store of construction and finishing materials of the Mercury Group of Companies recommends using a base for gluing walls from trusted manufacturers; The most popular brands of goods by customers:

• Polyfom, Globex, Echokit, Penolon.

The backing material Polifom, Globex, Echokit, Penolon is made of hygroscopic polyethylene foam, which on both sides has a special paper coating impregnated with a special composition that provides excellent adhesion to the wall. The thickness ranges from 4-5 millimeters.

The coating has different colors, textures, lengths, and is sold in rolls.

It is recommended to use a paper lining before gluing textile wallpaper, thin and light materials, as well as for heavy and vinyl wallpaper. It is ideal for both wall and ceiling work. There are several types of foundation, which we will now look at.

Types of paper backing for wallpaper

• For heavy wallpaper, a denser and thicker base is suitable, capable of supporting the weight of the main decorative coating.
• Thin ones may not be dense enough so that the base does not show through; it is recommended to choose a substrate of a suitable color.

How to glue backing paper under wallpaper

The waste paper backing is glued using a special glue for paper wallpaper. The surface of the wall is first lubricated with glue, and then the paper panel. To reduce glue consumption, thick paper can be pre-moistened with water. When gluing the base, you must follow the main rule:

• paper made from waste paper is glued not vertically, but horizontally from bottom to top. Remember this important nuance!

This method helps to avoid overlaps between the joints and the joints of decorative wallpaper. Thin paper is glued overlapping, and a thick base is glued end-to-end. It is also important to take into account that at least two days must pass for the paper to dry completely, only after that it will be possible to begin gluing the main wallpaper.

Waste paper does not exempt you from preliminary cleaning the walls from the old coating, leveling the surface of the walls, puttingtying them and priming them. All these operations must be performed with the same care as when gluing wallpaper without a backing.

Wallpaper backing is one of those materials that, at first glance, it would seem, is not as noticeable as some others. However, their role in interior design is no less important than that of any decorative coating.

What is it used for?

The backing for Ecohit wallpaper, as well as its analogues made by other manufacturers, is usually made on the basis of a special material - polyethylene foam. Usually it is covered with paper on both sides. However, many companies also sell cork and non-woven insulation backing. In addition, foam backing may sometimes be found. Regardless of the base material used, they all have very positive reviews from both professional craftsmen and ordinary people whose activities are not related to repair and construction. This soundproofing surface also has certain insulation characteristics, thus combining several useful functions at once.

As for the types of wallpaper that can be glued over the backing, they can be different: paper, non-woven, vinyl, textile. Speaking about the main advantages of such coatings, first of all I would like to mention the following:

• Eliminates the likelihood of microorganisms, mold and mildew (read more about).
• Provides additional sound insulation due to sound-absorbing properties.
• It has strength and a high level of durability.
• Absolutely harmless to human health.
• Acts as additional insulation.

Cork is an interesting option that can even be used instead of wallpaper

All this points to multitasking, which indicates the wide versatility of this kind of substrate. Another interesting quality is the ability to re-glue the wallpaper several times without causing damage to the substrate itself.

Some features

In addition to all of the above, we must not forget about the possibility of using it not only as a soundproofing and noise-insulating “lining” for wallpaper, but also for leveling walls. Of course, we are talking about leveling only minor mechanical damage, such as chips, scratches and cracks on the wall surface. If the wall is severely damaged, then in such cases you will have to take more serious measures.

By the way, its gluing is also associated with certain features that cannot be ignored. So, one of the most important conditions is that the wall surface should be pre-prepared. Preparation involves not only removing, but also getting rid of any remaining paint and glue. In addition, in cases where there is significant surface damage on the wall, it is advisable to level it using putty. After this, the wall must be coated with a layer of primer (using heavily diluted wallpaper glue is allowed).

Attention! It is better to use adhesive for gluing the backing that is intended for gluing so-called “heavy wallpaper”.

Sticking

Be that as it may, let's take a closer look at how to properly glue this roll material. At the same time, you will be able to stick it on with your own hands, doing all the work yourself. In fact, in essence, the work is practically no different from gluing other roll wall coverings, with the only difference being that a lining is used instead of wallpaper. However, the general technology remains the same. In any case, both according to the reviews of craftsmen and the testimony of ordinary buyers, this approach (using glue or thick wallpaper) is completely justified, and the results are quite good.

So, first of all, you will need to cut the canvas into separate sections, the size of the height of the wall. Then they will need to be straightened. To do this, you can use small weights or any small objects at hand, but with sufficient weight to level the sheets.

Helpful advice! After gluing, it is advisable to additionally glue the seams with masking tape or ordinary tape. It is desirable, however, that they be transparent (this applies to adhesive tape, since masking tape cannot be transparent) or at least light-colored. Something darker may appear during subsequent wallpapering in white, beige, light green and pastel colors.

Another useful piece of advice from experts in their field is that, both during gluing and after completing all the work, you should make sure that there are no “bubbles” left under the backing. Otherwise, you risk getting unevenly pasted wallpaper and all the work will be in vain: you will have to redo everything again. Wallpaper backing with Polif:

As noted above, it will be enough for you to stick the backing only once, and after that re-glue the wallpaper many times. As for the preparation before gluing, you need to remember to fulfill the following conditions:

1. Apply a layer of wallpaper paste or primer in advance.
2. After applying the glue to the substrate, you should not stick it on immediately after that. First, wait 10-12 minutes, and only then glue.
3. When air humidity is more than 70%, as well as at room temperature less than +10C, it is better to temporarily abandon gluing. So, it’s better for you to either reschedule the work or use a heater, which will raise the room temperature and lower the humidity.
4. And finally, one more useful tip: Try to avoid drafts after applying the sticker.

Popular brands

Among the most common manufacturers on the Russian market, as well as other CIS countries, the following brands can be mentioned:

• Polyf (also known as Poliform).
• Ecoheat, from the manufacturer Isolon
• Penolon.
• Globex (Globex).
• Penohome.

Many buyers, considering popular brands, wonder which is better? In fact, it is difficult to draw clear conclusions and choose just one of them, since the products of all major manufacturers are of a high level of quality. As for the form of release, most of them (polyethylene foam, cork, and so on) are produced in rolls, thus reminiscent of more traditional and familiar wallpaper to all of us.

Ecohit is one of the market leaders

Main advantages

We have already briefly listed the main advantages of using such materials. Let's take a closer look at the advantages that using wallpaper underlay can provide. However, in addition to them, there are also points that can hardly be called exclusively a plus, since we are talking more about features or technical/operational characteristics. So here's what to take into account:

1. The use of such materials can be extremely useful in the case of residential (and not only) buildings and premises that do not have high thermal insulation characteristics. Thus, the substrate is a kind of “supplement” for the insulation, if any. What buildings are we talking about? First of all, these are country houses, “panel” buildings built in the 1960s and 70s, and other similar “cold” buildings.
2. It is better to avoid using it in places where there is a constant presence of moisture. We are talking about baths, bathrooms and other similar premises.
3. On the other hand, it is quite acceptable to use it in such places of the apartment as the kitchen, living room (hall), hallway (corridor), bedroom and even.
4. In cases where fungus and mold have already formed on the surface of the wall, it is necessary, first of all, to get rid of them, and only after that glue the backing.
5. You should also realize that putting cork on the wall instead of wallpaper is, of course, a possible option. However, in such cases it must be glued very carefully to avoid the appearance of joints between the individual panels.
6. Despite providing some level of additional sound insulation, this material cannot completely rid you of excess noise that comes from the street or from overly loud neighbors. So, don’t expect complete silence to reign in your room.
7. At the same time, circumstances such as complete safety for human health (including children), which allows it to be used in any room of the apartment, including.
8. The ease of gluing, which can be done by almost anyone without relevant experience, is complemented by an affordable cost.

Conclusion

Despite the fact that some people are not very familiar with this material, and some do not even know what a wallpaper backing is, reviews from craftsmen, as well as some ordinary buyers who have had experience in repairs using it, indicate that this is an excellent auxiliary material that will be very useful when working with wallpaper of any type (paper, vinyl, non-woven, textile, fiberglass, and so on). Wallpaper substrate Ecohit, Polifom, Penolon - reviews of these coatings, in most cases, are very positive, since many of those who have tried to use it advise others to do so.

Today, more and more attention is being paid to energy saving technologies. So, the use of such materials is very appropriate in this context. As for where to buy a lining of a particular brand, as well as questions about price, what can safely be said is that there is a wide variety of options on the market, from the most inexpensive to quite expensive. If you are already thinking about purchasing, we can recommend both large construction hypermarkets (and others) and small companies that often offer goods at very attractive prices. In addition, we cannot help but mention specialized online stores.

The walls in the house should not only be beautifully finished, but also perform their function - reliable noise and heat insulation. So it’s not enough to choose beautiful wallpaper and think through the design of the room. First you need to prepare the walls themselves. This is done using a wallpaper backing. The use of such material will significantly improve living conditions in an apartment or house.

Functions

The substrate consists of several layers. In the middle, as a rule, there is foamed polyethylene, enclosed between layers of paper.

The wallpaper backing is a reliable insulator, which can be an important advantage in houses or apartments with cold walls.

Many multi-apartment “anthills”, both old and new, do not have good sound insulation. Residents hear other people's conversations, and not only in raised voices, but also music and harsh sounds from their neighbors. All this is unnerving and does not allow you to live in peace. Sound insulation is ensured by using a wallpaper backing. This material also allows you to overcome the problem of indoor humidity.

It is an excellent lining for any wallpaper. Using it, the outer decorative layer is easier to glue and it will look better on the walls.

Using a backing allows you to achieve maximum adherence of the finishing layer, even in problem areas such as corners and joints.

As a result, the finish will last longer and the problem of new repairs, as well as the material costs associated with it, will be postponed. Once upon a time, old newspapers were used as a backing. It was easier to glue wallpaper on them. Technology has come very far since then. Taking into account all the possibilities of modern substrates, their use cannot be considered a whim.

Types and composition

The buyer can choose from several varieties of this roll material:

Paper

The backing base consists of paper. Its use is especially useful in cases where it is problematic to get rid of traces of the old finish. It sticks to the wall surface better than wallpaper. Its disadvantage is that it does not hide obvious flaws in the wall. In addition, this particular substrate is not particularly strong.

Non-woven

Externally similar to non-woven wallpaper, just as durable and easy to glue. At the same time, it is an expensive substrate. Not everyone will decide to buy it.

Cork

It is created on the basis of technical cork, and not decorative, so it is cheaper than finishing material made from cork. Its great advantage is its excellent sound absorption, which is indispensable if the house has thin walls and everything can be heard. But it needs to be installed skillfully and using special glue.

Polyethylene

This is a sandwich in which there is foamed polyethylene between two layers of paper. This material perfectly masks imperfections on the wall surface, and thanks to the inner layer it acts as a sound and heat insulator. It turns out to be an improved version of polystyrene foam, which is traditionally used to ensure silence in the room.

Benefits of use

In addition to the sound and heat insulation function, this material has many advantageous characteristics. The advantages of its use lie in the fact that it is environmentally friendly and therefore applicable in any home. The surface of most substrates does not absorb liquid. Accordingly, condensation does not form on it, and it will be able to protect the house from fungus for decades.

This coating partially levels the base on which it is located. Small cracks and chips on the surface can be successfully hidden using this material.

Its properties do not change for at least twenty years. Some manufacturers give it a half-century guarantee. Therefore, having once spent money and time on the purchase and installation of such a substrate, you can make your life easier with subsequent repairs, when you have to change the wallpaper again and again. The soundproofing feature of this material will be especially noticeable where walls separate the interior space from the street and common corridors. Good thermal insulation in these cases will also demonstrate itself successfully.

How to glue correctly?

Practice shows that wallpaper backing adheres remarkably well to concrete, wood, plywood, and drywall. In order to firmly glue it to the surface, you need to prepare the walls themselves for this: tear off the old wallpaper, remove any remaining paint, level out the depressions and seal the cracks with putty or cement mortar. Then you need to prime the surface. PVA glue or some other similar composition will do for this.

The backing strips themselves must be prepared for sticking to the walls in advance. They cut very easily. They must be divided into sheets taking into account the height of the walls and these sheets must be allowed to align.

So that they have time to straighten out, it is better to carry out the cutting a day before the start of pasting the walls.

Smooth sheets of material are coated on the inside with PVA glue or glue that is used for heavy wallpaper or under polystyrene. If there is a high level of humidity in the room, use baguette glue or liquid nails. (This, of course, will be more expensive, but you can be sure of the quality of the repair).

Considering all this, you need to act so that the glue does not get on the joints. Otherwise, the pieces of the backing will stick together and the seam between them will be uneven. The canvases with the applied glue are left for five to ten minutes, and then they are glued to the walls joint to joint - just like most modern wallpaper. In this case, the wall must also be coated with the same glue before this. Note that if the outer layer of the backing is non-woven and not paper, then only the wall itself needs to be coated with glue.

To ensure maximum adhesion to the wall surface, use a rubber roller, with which you squeeze out all the air from under the substrate and carefully roll it along the wall.

The gaps between the canvases must be sealed with paper tape or paper tape. To ensure that the result does not disappoint, just as in the case of wallpapering, drafts should be avoided. Experienced people advise carrying out the work itself at temperatures above +10 degrees and humidity less than 70 percent. If the room is cold, the glue will not set, but if, on the contrary, it is too hot, it will dry very quickly, and you may not have time to fix the entire substrate on the wall. Some areas will not be glued. Taking these features into account, it is recommended not to undertake such repairs in the spring or autumn, when there is high humidity and strong temperature changes.

After the job is done, you need to wait two days and only after that start decorating the walls with wallpaper.

Offers from manufacturers

To choose the right backing for wallpaper, you need to keep in mind the experience of finishing professionals. The market offers wallpaper substrates of both foreign and domestic production. They can be found both in building materials stores and specialized wallpaper stores. Substrates from different brands may not be the same in thickness and material composition. So their cost sometimes varies greatly when compared.

“Ecohit”, “Penohome”, “Globex”, “Penolon”, “Polifom”- These are the most famous manufacturers of wallpaper substrates. Among all the brands under which such materials are produced, experts highlight domestically produced Penolon and Polifom. "Penolon" has good thermal insulation properties. This is achieved due to air cells in its structure. The thickness of the material is only 5 millimeters. Roll width – 50 centimeters. A total of 14 meters per roll. At its core, Penolon is a chemically cross-linked polymer.

There are several varieties of such polymers - non-cross-linked gas foam, physically and chemically cross-linked. The cheapest among all is non-cross-linked polyethylene. In terms of strength and thermal insulation capabilities, it is 25% worse than physically and chemically cross-linked polymers. The last two, despite the fact that their manufacturing technology is different, are very similar in their characteristics. "Penolon" is hygienic. It is light and elastic. Resistant to alkali, acid, alcohol and gasoline. Easily straightens before sticking. Has low vapor permeability. Suitable for leveling surfaces, suppresses noise, eliminates cold coming from the walls, allows you to properly glue wallpaper, and eliminates the effect of “crying” walls.

“Polif” (sometimes also called “Poliform”) has the same geometric parameters as “Penolon”. It is also 14 meters long with a canvas width of 50 centimeters and a thickness of 5 millimeters. This is an environmentally friendly material that does not absorb moisture and prevents the spread of fungus and mold. This is a reliable heat insulator.

When choosing a material experts advise paying attention to the color of the roll - it should be white or light gray. It also matters how firmly the paper layer is attached to the base. High-quality material is odorless and has a certain elasticity - after pressing with a finger, its surface should quickly return to its shape.

• When choosing a backing for wallpaper, it is better to focus on the reviews of craftsmen who have already gained experience in handling such materials, know all their pros and cons and how to use them correctly.
• You also need to keep in mind that before using such materials, if there is even the slightest hint of the presence of fungus, the wall surface must be treated with special chemicals. The underlay should not be used in baths and bathrooms.
• In rooms where the humidity is quite high, it is preferable not to use paper backings, since the paper itself does not tolerate dampness well. In these cases, it is better to use products made from non-woven fabric or cork.
