How to glue plastic film to wood. What kind of glue to glue foamed polyethylene with?

Greetings! In articles about insulation, the use of penofol is constantly recommended, but I had a question, how to glue penofol to concrete, for example, if I am using a non-self-adhesive option? Thank you.

Hello. We will try to answer your question.

Penofol is an energy-saving material with a layered structure. It combines the properties of foamed polyethylene and thin aluminum foil. The material is characterized by lightness and low thickness, and therefore is often used on various objects(including on the balcony) for insulation, ensuring tightness, thermal, noise, steam and waterproofing. However, to ensure high-quality protection, it is not enough to lean penofol against the insulated surface - you will need special glue for penofol.

Features of adhesive installation of penofol

Adhesive for foil foam foam allows you to quickly complete work on insulating surfaces. Besides, glue method installation is easy to implement and low-cost, since it does not require any special skills or specialized tools.

Usually, when choosing gluing as a method of installing insulating surfaces, you need to take into account bearing capacity adhesive layer - but when using penofol, this fact will not be decisive, since the material is incredibly light.

Rules for preparing surfaces before gluing

Correctly selected penofol adhesive is not a guarantee successful implementation works To ensure the integrity of the connection, the main thing is that the surfaces to be glued are prepared. All defects, chips, unevenness, cracks, as well as dust must be eliminated on them.

Important: Surfaces made of metal, concrete or wood can be additionally primed for better adhesion of the layers.

One of the most important conditions quality result - evenness and cleanliness of the surface. Thus, concrete floors and walls are leveled, cracks are eliminated, and metal elements treated with anti-corrosion coating.

What can be used as adhesive for penofol?

Penofol adhesive can be special or universal. For these purposes, professionals also allow the use of liquid nails, double-sided tape, thin layer polyurethane foam. The choice of the type of adhesive depends on both the purpose of the surface and its further design.

It is very important here that the characteristics of the adhesive composition correspond to the performance indicators of the insulation:

ability to withstand operating temperatures in the range of +100…-60°C;
permission for indoor use;
biological non-toxicity;
adhesion resistance.

If insulation is carried out outside, on the facade, then the adhesive composition must be resistant to water vapor and water. Non-toxicity requirements are also mandatory, since the balcony belongs to residential premises. Therefore, adhesive for foiled penofol must certainly have hygienic safety certificates.

How to properly glue penofol

To correctly glue penofol, you need the selected adhesive composition Apply to the side of the material that is not protected by foil. It is important to apply the glue evenly thin layer and so that all areas of the insulation are coated, without gaps.

When coating, special attention is given to the edges of the panel so that the penofol does not begin to peel off during operation. In order to fix the insulation, the material must be kept for 5-60 seconds so that the glue applied to it dries slightly. This will ensure better adhesion of the composition. Then the prepared canvas is pressed to the surface to be pasted, held and very carefully smoothed - until it is completely fixed.

If penofol is fixed in pieces with seams between them, then these same seams are additionally glued.

Required tools and materials

To get started, stock up on everything you need for work. You will need some double-sided tape, depending on the amount of polyethylene you need to glue. To weld, you will need a soldering iron, but if you don’t have one, you can use an iron. In this case, you need metal plates - 2 pieces, as well as a piece of cotton fabric.

In addition, you will need butyral phenolic and chromic anhydride glue. The latter should have a concentration of 25%. By the way, you can use chromium as a replacement.

Finally, be sure to stock up on funds personal protection, because working with chemicals may be harmful to your health.

The first and easiest way is to use double-sided tape.

If you need to connect the ends of the film and polyethylene, you can use tape. Be careful: this method does not imply further withstanding increased load.

Before gluing polyethylene double-sided tape Be sure to thoroughly clean the surface of the film. This is necessary so that the tape sticks most tightly to the surface and lasts long enough. Dust and dirt interfere with normal adhesion. Remember that the tape needs to be changed from time to time and try not to expose it to moisture.

Welding

This method is used most often because it is considered the least expensive, but at the same time very high quality and durable. Important: you must carry out the work with extreme caution, because there is a risk of not only spoiling the material itself, but also getting burned.

The most commonly used method is bonding with plates. To do this, place the two edges of the polyethylene sheet that need to be glued on top of each other between the metal plates. The edges should protrude slightly. Gently press the plates and run the soldering iron along the very edge of the polyethylene. In this case, plates are necessary to ensure that the film simply does not curl under the influence of high temperature.

If you don't have a soldering iron, you will need an iron. Place the pieces of fabric to be glued slightly overlapping (1 cm). Lay strips of cotton fabric under the reverse side of the polyethylene and on it. After this, run the iron, heated to maximum temperature, over the fabric from above.

The stores have a large quantity of the most different glues for plastic. However, keep in mind that the vast majority of compounds are not suitable for polyethylene. But do not discard this method - you can use it for gluing polyethylene standard glue for plastics after careful preparation of the material.

In order to make the surface of polyethylene more active for adhesion, you will need chromic anhydride or chromium. Such products are sold in specialized chemical stores. If you have chemist friends, you can ask them for the composition. Chrome gently acts on the surface of polyethylene, making it receptive to glue.

Anhydride or chromium should be applied to the film, and only then the usual BF-2 glue, which is sold in every store. Such a simple method of gluing polyethylene would become very popular if the necessary chromium-based substances were easier to obtain.

Special glue

Finally, there is another method for gluing polyethylene. Currently, a special glue has appeared in stores that is intended only for this material. It can be an adhesive for plastics or a structural adhesive for materials such as polypropylene and polyethylene.

The glue is applied to the clean surface of the film. However, it does not need to be treated with any substances. The fact is that after applying the glue, polyethylene begins to change its structure, which makes gluing simple and reliable.

What you need to remember from chemistry and physics

Polyethylene is the most common polymer in the world. Its extraordinary popularity is explained by the excellent properties of the material - impact resistance, ductility, low gas and water permeability. Films are used for roofing mesh reinforced or fabric, which increases the strength of the material.

Despite the advantages, polyethylene films are very rarely glued together in industry. To understand why connecting parts is problematic, just remember your school chemistry lessons. The molecule of this polymer is a long chain of similar -CH2- units. The charges inside such a molecule are distributed evenly, it is non-polar. And the higher the polarity, the more suitable the polymer is for gluing.

This device is suitable for small parts

Connection methods without glue and solvent

The method of gluing with its own solution, which is common for many polymers, is also not suitable - polyethylene is practically insoluble in organic solvents. The answer to the question: how to glue polyethylene film is actually very simple: it is best to use welding.

Of the many methods for welding polyethylene film, two are worth highlighting:

Welding with a heated object.
Open flame welding.

Both methods are equally effective, but not industrial conditions it's still easier and safer to use the first one. However, everyone can choose the most suitable option for themselves, taking into account the availability necessary tools and your own skills. In any case, these methods make it possible to firmly connect parts together, creating reliable building elements, agrotechnical and protective structures.

Preparatory stages for work

Folk wisdom says: “Measure seven times, cut once.” And before starting to work with polyethylene, you need to not only carefully take measurements, but also think through every detail. First of all, answer the questions:

What loads will the finished structure be subject to?
What is its expected lifespan?
Do you need 100% hydro resistance?

Maybe after such questions the need to glue together many parts will disappear. For example, to insulate transported goods or preserve equipment, some parts of the plastic film can be secured with metal staples or twine. And for protection building structure to protect against moisture, it is recommended to overlap the polymer, covering individual parts.

But when the question arises about how to glue reinforced film for a greenhouse, you should not neglect reliability. After all, such a design, as a rule, should serve for a long time, perfectly protecting plants from all kinds of weather surprises. Connecting with staples and strong ropes will not work in this case, and welding (any of the proposed types) would be an ideal option.

Hot Welding Instructions

This method can be called the simplest, most effective and safe at the same time, especially when it comes to welding at home. An ordinary iron can be found in every home, and seams created using heated objects are usually the smoothest and neatest.

Universal roller for gluing polyethylene

Most convenient tool For this method, a roller with a built-in electric heating device can serve. This tool is ideal in cases where a large amount of work needs to be done - for example, in large agro-industrial enterprises. As a rule, such devices have to be made independently. And for them to work well, you must at least have a qualification as an electrician.

However, when it comes to how to glue plastic film for a greenhouse at home, the roller method is not very suitable. After all, not everyone has the time, patience and necessary skills to create such a device, especially when the need for welding rarely arises. Then you should resort to the help of improvised means. And in everyday life there are a lot of devices that can be heated to the required temperature – approximately 250°C.

How to work with an electric iron and analogues

To glue polyethylene using an iron, you just need to lay the edges of the material on a wooden strip, and then iron the parts through a newspaper or fluoroplastic film folded in half. By the way, these same safety elements will not be superfluous when gluing with other hot objects. Depending on the area of the surface to be joined, you can use a narrow edge, spout or flat iron. A wooden slats will help create an even and neat connection.

To what temperature should the iron be heated? Unfortunately, there are no clear recommendations on this issue, and 250°C is rather a relative indicator. The melting point depends primarily on the brand of polyethylene. Therefore, you need to be very careful while working. If the material does not connect and does not change at all, it means that the iron needs to be heated more strongly. If the seam is barely noticeable, and the film near it has lost its strength, the temperature is already too high.

There is always a risk of burning through the film. To avoid this, you need to reduce the contact between the iron and the parts being glued to one second. To prevent polyethylene from sticking to the iron, instead of newspaper, you can cover the surface of the polymer with thin cellophane before work. To check how effective polyethylene soldering is, you need to pull the connected parts in different directions. If the seam has come apart– the process will have to start again.

Soldering iron with a special nozzle

If the iron method is not suitable for some reason, you can use other tools. For example, a hot knife and a soldering iron tip will make it possible to create smooth and thin seam lines. Some craftsmen manage to connect polyethylene parts with a hot needle. However, you can use other available means. Auxiliary tools are the same as for joining with an iron - wooden frame, newspaper or cellophane.

Homemade soldering iron for gluing polyethylene

Open flame welding of film

You will need:

one of possible adaptations with open fire: gas-burner, alcohol lamp, blowtorch, match, torch;
bars made of ceramic or metal.

First, the edges of the film are fixed with bars so that a narrow strip of polyethylene several millimeters thick is visible at the welding site. The bars should be made of metal or ceramics, but in no case from wood - after all, their function is not only to keep the polyethylene immobile, but also to remove some of the heat so that the parts being connected do not burn out.

After this, the tool selected for welding must be conditional line along the edge of the polyethylene parts. As a result, a dense connecting bead should form at the point where the films come into contact with the open fire. For the welding process to be successful, it is advisable to first empirically, select the optimal tool speed. It depends on the device used and on the brand of polyethylene.

It is better to use the device on the roof

Is it possible to glue the film with glue?

Some craftsmen tried to use BF-4 or BF-2 to glue plastic film at home. After treating the parts with a 25% solution of chromic anhydride, they applied glue to the surface, but subsequently the seams plastic film I still had to handle it with an iron heated to 50-60 °C. As a result, this method differed little from joining with hot objects, even if the temperature was much lower.

Using super glue: a cutting-edge approach

The surface roughness contributes to the successful joining of parts with glue. But the properties of the polymer in question are opposite - it is characterized by ideal smoothness. And yet, how to glue plastic film for a greenhouse using only one of the ordinary factory adhesives? Until recently it was thought that this was impossible.

However, recently varieties of superglues specifically designed for working with polyethylene film have appeared on the market. Among the advantages of such products:

no odor;
water resistance;
elasticity;
strength of connections.

When dry, they can be diluted with acetone. However, they must be used with caution, avoid contact with skin and household surfaces, because they contain strong solvents.

Also worthy of attention are products based on ethyl 2-cyanoacrylate, which were developed by chemist Harry Coover during military experiments in the United States back in the middle of the last century. These types of glue are available today thanks to mass production, create fairly strong connections, and are also suitable for working with rubber and metal.

Is the choice of adhesive for joining parts justified?

Is it worth using glue for polyethylene at home, including for roofing works? One of the main problems when used in everyday life can be its toxicity. In addition, not all products on the market are of sufficient quality. And it is simply impossible to check the effectiveness of glue upon purchase. At the same time, when using one of the types of welding, there is a greater chance of getting excellent result.

Using glue for polyethylene

As you can see, there are many ways to glue plastic film at home, and everyone can choose the most suitable one for themselves. In addition, there is always the opportunity to turn to professionals who will not only give useful advice, but can also provide practical assistance.

IN construction work, often using foamed polyethylene material Izolon, the problem arises of how to attach it. One solution is to glue it. Almost all insulating materials, such as alufom, penofol and others can be glued, if appropriate.

For example, as in the photo, it is foil-coated for insulation and is additionally attached with glue.

How and with what to glue.

Usually, the balcony is first insulated with polystyrene foam boards, onto which foil polyethylene is glued.

To do this, you can use the following glue:

QUICK-BOND
88-NP
Akrol contact
spray "Neoprene 2136"

The joints are sealed or overlapped.

You can glue the foam to the foam or to another surface using the following glue:

CEREZIT ST83
ANSERGLOB BCX 39
AQUALIT SK-106 P (polymer cement mixture)
MASTER SUPER
POLYMIN P-20
STOLIT PC and TYTAN STYRO 753 O2 (aerosol polyurethane)

How to glue foamed polyethylene to the wall

For example, to insulate a home, you need to glue the screen behind the radiator.

Cut out right size foil Penofol with polished aluminum foil 3-5 mm is usually used.

The screen can be fixed double-sided tape or stick it on.

Today, it is the most popular adhesive on the market due to its versatility and wide application. Retains its properties in the range from -30C to +90C, and is used both in everyday life and on an industrial scale.

To use it correctly, carefully study the instructions for using the glue; it has a large number of varieties.

For large volumes of work, glue is available in packages starting from 25 kg.

Such as for example:

adhesive mixture "Facade"
BOLARS

Although polyethylene foam is recognized by many foremen as universal insulation, but to secure it to the surface of a building structure or gluing sheets, heat insulating material between each other, you need to use a special glue for foamed polyethylene.

The main advantages of foamed polyethylene

Despite being on sale thermal insulation materials, the production of which began later than foamed polyethylene, insulation of the brands Izolon, Temaflex, Polifom, Penofol are in consumer demand because:

the material has low thermal conductivity;
the air-bubble structure of the insulating material prevents the spread of water vapor and the penetration of precipitation;
the small thickness and high flexibility of the material facilitates installation, and the adhesive for polyethylene foam ensures its reliable fixation on the surface of building structures;
if foamed self-adhesive polyethylene is used, installation of the heat-insulating layer is greatly simplified; it is carried out at the joint, over which aluminum tape is glued;
if foil-foamed self-adhesive polyethylene is used, then after insulating the surface of the building structure with Penofol, it even acquires a certain beauty.

Adhesive mixtures for polyethylene foam

Experts, when recommending how to glue foamed polyethylene, suggest two-component mixtures based on methyl acrylate. For example, the well-known mixture from the Weicon company - “Easy-Mix PE-PP”, which demonstrates high adhesion, allowing you to work even with polypropylene and simple polyethylene.

“Quick-Bond” or “88-NP” (universal adhesive for this material;
Akrol contact;
spray "Neoprene 2136".

If you need to glue foamed polyethylene together, you can use:

Cerezit CT83;
Anserglob BCX 39;
polymer cement mixture called “Aqualit SK-106 P”;
"Master Super";
"Polymin P-20";
polyurethane aerosols “Stolit PC” or “Tytan Styro 753 O₂”.

The wall must be pre-cleaned, treated with an antiseptic, dried, and, if necessary, leveled. When fixing insulating material over large areas, we recommend using the adhesive mixture “Facade” or “Bolars” (packaged in 25 kg), pre-preparing the working solution in accordance with the manufacturer’s instructions.

Foamed polyethylene is often used for insulation and waterproofing, but for an effective and high-quality result, special glue must be used in tandem with polyethylene.

There are several types of glue:

For exterior finishing and insulation, mounting adhesive for exterior use or liquid nails, which have high degree strength, resistant to temperature changes and adverse weather conditions;

In a room with a high degree of humidity, in baths or a bathroom, you will need MV-40 glue, which does not lose its adhesive qualities in a damp environment and has water-repellent properties;

When insulating the inside of houses, apartments and other residential premises, you should choose a non-toxic adhesive labeled “universal” or “express”.

There are also professional adhesive-based mixtures that have high performance and perform their functions perfectly. When dry, this mixture acquires a similar structure to the material, which gives solidity to the bonded surfaces. Right choice an adhesive composition will help make the insulation of the room not only effective, but also durable.
