How to glue wood to metal?
Until the Second World War, there were no means to glue wood and metal together. For the first time, the British used rubber-based glue to glue wood and metal parts in their fighters. Now there are no problems gluing wood and metal.
In addition, silicone rods appeared, which, when heated, form an adhesive mass and tightly glue metal and wood products. These adhesives are convenient and so. that their excess can be easily cut off with a knife. Currently, many have come across Supergrip glue. You can also use epoxy
Permabond ET515 or POXIPOL, these two-component adhesives have long been known to many as " cold welding". This is what these adhesives look like.
Use rubber-based adhesives, such as, for example, "PATEX", "88N", "ELASTOSIL-2", "KR-1", "Zh-3" and others.
The most important thing is the preparation and the gluing process itself. It is important to understand that the metal surface is oxidized under the influence of moisture and the oxidation film exfoliates from the material along with the adhesive, so the whole process must be carried out in a dry room.
Treat both surfaces first:
- treat the wood with a solvent and dry the surface.
- work the metal first sandpaper, removing the oxides, then rinse with a solvent and dry, then wipe thoroughly with a solution of nitric or sulfuric acid and also dry.
Next, a layer of glue is applied to the surface of metal and wood and, without pressing the materials against each other, they withstand them for a specified time period, depending on the instructions. Basically it is about 10 hours, but no more.
Now glue is applied to both surfaces again and connected to each other, laying the connected parts under a press or pulling them together with a clamp - this is a must, otherwise it will not be a high-quality gluing.
Also, apart from rubber adhesive bases offer to glue these two materials with silicone rods, which belong to the hot-melt adhesive group, but I personally am not familiar with technological process, although I can assume that the silicone is first applied to the metal, and then the wood is pressed against the surface. But for hot melt adhesive, small surfaces are good, where you can maintain the temperature of the glue in one mode until the moment of gluing.
To glue wood to metal, of course, the wood must be dry, and the metal must be free of rust and dirt, you can use a heat gun.
The molten polymer in the thermal gun easily spreads well on wood and metal, and when solidified, it firmly fixes the details, look at the photo, wood, metal, anything you can stick to anything!
If, of course, a more aesthetic connection is needed, then I would recommend using two-component epoxy-based adhesives - Of course, the cost of gluing will be many times more expensive, and it will take longer to wait for the result, but the connection will look more aesthetic, probably the same in quality and strength!
Before gluing two surfaces: wood and metal, they must first be prepared, cleaned, degreased. Sand the metal surface with fine-grained sandpaper, rinse clean water. Do not wipe the surface, the water should dry naturally. Apply to wood and metal surfaces thin layer synthetic glue and leave for several hours to dry the glue. Then once again grease with glue, press against each other and leave under pressure for a day. Rubber glue is suitable for gluing, for example, KR-1, Patex, Elastosila-2.
wooden and metal surfaces can be glued together with double-sided adhesive tape.

Joinery is based on precise fitting and gluing of parts, and it is the last part that is responsible for the strength and durability of the product. There are quite a few varieties of wood adhesives, and today we will talk about the difference between them and the rules for use.
General classification of wood adhesives
The modern assortment of glue for carpentry includes more than a hundred items. Therefore, to begin with, let's briefly go over the types of glue, their properties and the most popular brands.
By origin, all types of glue can be divided into compositions of natural origin and synthetic. In turn, natural adhesives may include animal binders and plant origin, synthetic ones are divided according to the method of production into condensation (formaldehyde) and polymerization (PVA, polyamide). The list of natural adhesives includes compositions based on casein, collagen and albumin, chemical compositions include PVA, formaldehyde, PVC, epoxy, as well as most universal types of glue. As you might guess, adhesives of natural origin are most widely used, primarily due to their low cost and well-established production technology.
Wood is a material with high porosity, which means that almost any adhesive composition can be used for gluing. However, since most of the joinery is operated in household purposes, it is not customary to use adhesives based on volatile solvents for their bonding. This is the second advantage of natural glue - it provides sufficient strength despite the fact that it does not emit environment no toxic substances.
However, for a number of products it is required to provide resistance to different kind external influences. Mostly, the struggle is over increasing moisture resistance, because most varieties of natural glue lose strength when wet. Increased adhesion may also be required, mainly such a need arises when gluing parts made of hard and dense species of small-vessel wood. Here, the best performance is demonstrated by compounds on synthetic adhesives.
How to choose the right glue
If you are not a professional carpenter, do not be intimidated by such a variety of wood bonding compounds. You can go the easier way - use time-tested types of wood glue, environmentally friendly and with a certain set of special properties.
Glue of natural origin is supplied mainly in dry form and must be prepared before use. The main disadvantages of natural adhesives are a short lifetime (up to 2-3 days) and low strength of joints due to a low degree of chemical purity and errors made during preparation. Wherein natural glue — optimal choice for bonding non-critical parts with a large area of adjacent surfaces.
As a universal adhesive, most joiners use factory-prepared compositions based on PVA. Well-established manufacturers - Titebond, Kleiberit, "Moment", they are listed in order of decreasing cost of products and, accordingly, quality. Such types of glue are classified according to the reliability and quality of the connection by index D with four serial numbers. The higher the number, the more pronounced the moisture resistance and strength of the seam, and additional properties. So, Titebond III glue, aka D4 in general classification, allows contact with food products after drying, this glue is mainly used for assembling end cutting boards.
If the contact area of the parts to be bonded is low, high bonding accuracy or load resistance is required, it is better to use compounds based on synthetic resins. Even ordinary EAF epoxy resin in such cases will give odds to any water-soluble adhesive. It is especially advantageous to use it for gluing hardwoods, including thermally modified ones, as well as when joining wood with foreign materials.
Bonding wood to plastic with epoxy
Preparation of parts for gluing
When gluing wood, general rules fulfillment adhesive joints. The fixation will be the stronger, the smaller the thickness of the adhesive seam, deeper impregnation and below the content of foreign impurities. For these purposes, the surfaces to be bonded must be carefully prepared.
Gluing wooden parts carried out to final polishing. Pre-contact surfaces must be carefully sanded with abrasive paper with a grit of at least 300 grit to remove fine pile that interferes with the absorption of glue. It is important to remember that the cleaned surface is suitable for gluing only for a certain time: over time, the top layer of wood oxidizes, the vessels are clogged with dust and new portions of pile rise.
When using a water-soluble adhesive, degreasing is not necessary. However, when gluing on epoxy resin or polyurethane hot melt adhesive, it is desirable to remove residues of wood resins and natural secretions from the surface using concentrated technical acetone. The humidity of the parts to be glued should be mentioned separately: a moderately high moisture content (20-22%) when working with water-soluble adhesives slightly slows down the hardening process, but at the same time promotes deeper absorption and ultimately has a positive effect on the strength of the joint. But when using adhesives on liquid resins, an increased (more than 12-14%) moisture content is categorically unacceptable, therefore, the adjacent surfaces are pre-dried with hot air for 2-3 minutes.
Application of glue and curing
The adhesive is applied to the surfaces to be joined as evenly as possible. The thickness of the layer should be as small as possible, but at the same time sufficient to compensate for the curvature. The presence of air cavities in the adhesive seam affects the reliability of the connection extremely negatively. Particular attention is paid to seams with an uneven thickness, reaching a peak of several millimeters: in such joints, it is recommended to mix the glue with wood flour or cellulose fiber.
In certain cases, the adhesive does not have the main fastening function, but is used as a plastic filler. Such situations include the strengthening of the joints on the spikes and lamellas with glue, and the splicing of wood by the groove and micro-spike method also partly belongs to this category. In such cases, the glue is applied with a clear excess, after which quite painstaking work is carried out to remove the protruding residues.
It is convenient to apply glue on even and smooth surfaces with a small flexible spatula, which can be used as a regular plastic card. In the grooves and small holes, as well as on the spikes and folds, glue is applied with a brush with synthetic bristles. When gluing parts with a large contact area, it is required to apply a large number of glue as quickly as possible so that it is absorbed evenly. For example, you can take all the same end boards and furniture boards: to glue several dozen bars, the glue is quickly rolled out over them with a roller. The same applies to sticking veneer, and gluing flat parts of plywood.
Almost all types of glue require exposure after application in the open air. Upon contact with oxygen, the adhesive undergoes primary curing, which speeds up the drying process. assembled parts. For PVA-based adhesives, the exposure time can be up to 20-30 minutes, for natural ones - up to several hours. Manufacturers may give special recommendations, for example, polyurethane adhesive is aged until the viscosity is completely lost, after which it is activated by temperature.
Positioning, compression of parts
Holding parts helps to increase the viscosity of the adhesive, which is good for keeping the parts in the bonding position. However, this approach is used mainly in modeling and the implementation of irresponsible glue joints. In most carpentry adhesive joints, rigid fixation of parts using clamps and stops is required.
Fastening parts with additional pressure not only allows you to maintain their position during the drying of the glue, which is almost always accompanied by shrinkage and warping of wood from local moisture. As the adhesive becomes more viscous, the pressure helps to push the compound that has not yet set deep into the pores, which increases the strength of the adhesive line.
AT carpentry used great amount clamps of various types and sizes. For gluing flat parts, you can also use the usual oppression, pressing the product to the table with a load of 7-10 kg. But to connect linear elements, it is necessary not only to withstand the corners, but also to squeeze parts that can be very overall. Ordinary linear clamps do an excellent job of this task; with a lack of length, an emphasis can be attached to the parts, but only if the place of its fixation is blocked by another part of the product. It is also widely practiced to temporarily fasten the stops to the clamps.
For gluing parts at an angle, clamps of a special shape are used, having two pairs of clamps and fixed jaws, rigidly fixed to the frame in a given position. This tool can be replaced with a number of fixtures, which is often practiced when gluing at angles other than straight lines. For example, wedges cut according to a common pattern can serve as a temporary stop. With this method of positioning, it is important that the pressing force has a direction as close as possible to perpendicular to the adhesive line. For these purposes, the occipital parts of the clamps and stops can take a variety of forms.
In conclusion, we give a couple good advice about how to ensure the invisibility of adhesive seams. Most wood adhesives have a translucent color for a reason. White color: after drying, minor streaks are easy to hide under a layer of protective and decorative coating. But there are also a number of exceptional situations.
For example, initially imperceptible traces of glue getting on wood are clearly visible when impregnated with oil. If such a coating of the product is planned, it is necessary to work with glue as carefully as possible. Excess glue that has come out of the seam should not be wiped off immediately, it is better to wait for their preliminary setting, and then cut them off with a modeling knife. With streaks, the same story: attempts to wipe will only lead to deeper absorption, so it’s better to just blot the drop with a foam sponge, and after drying, clean the defective place with a cycle.
If it is necessary to remove small residues of adhesive that has come out, solvents can be used. Depending on the type of adhesive, these can be acetone (for most synthetic resin adhesives), isopropyl alcohol (for PVA-based adhesives), toluene (for universal rubber adhesives and epoxy resins), and ordinary soapy water (for natural reversible adhesives). Dried excess must be wiped off with an absolutely clean rag or cotton napkin strictly in the direction of the glue line.
Previously, the surface of both metal and wood must be well degreased. For degreasing metal, a solution of two parts sulfuric acid and one part nitric acid is best suited. Previously, the metal must be sanded with fine-grained sandpaper. The tree can be treated with a conventional solvent. Then the metal is well washed with clean water. You need to wait until the water dries without wiping the surface. After that, a thin layer of synthetic glue should be applied to metal and wood and dried. After ten hours, the surfaces are again smeared with glue, put under a press and kept for about a day. Usually, rubber adhesives of the type 88-HP, KR-1, Zh-3, 88-H, Elastosila-2 and Pateks are used in this case. Rubber adhesives are convenient because the excess is easily cut off - this gives the products a marketable appearance.
During the Second World War, the first result was obtained for gluing metal to wood, and the British released the first, which used wooden structures connected to metal with rubber glue.
You can also glue wood and metal with a silicone rod, which is sold in any hardware store. You should buy a rod, heat it up with a lighter, grease the metal surface and stick it to the tree.
Another popular method is gluing wood and metal with epoxy resin. For example, a two-component epoxy resin Permabond ET515 or POXIPOL, popularly known as "cold welding", is suitable. Another option is a two-component glue "Supergrip". In any major hardware store there is a wide range of adhesives that will help solve the problem of gluing metal and wood.
How to glue metal to wood with duct tape
Adhesive tapes are a new word in the construction industry. The very difficulty of gluing metal with plastic or wood lies in the fact that these materials have a different coefficient of expansion when heated. Therefore, the construction idea came up with double-sided foam-based adhesive tapes.The range of such tapes is quite high, allowing the client to choose exactly the one that suits his case, because metals and wood differ significantly in their characteristics. Adhesive tape does not present high demands to cleaning surfaces, and the quality of gluing here will be very high. Most popular in the market adhesive tapes MetalShelfTape, DUBLFIXHIGHBOND and DHB-04.
If necessary, such tapes can be easily removed from hard surfaces, metal and wood without leaving any traces behind.
When deciding to glue with any other surface, you must take into account several factors at once, on which the success of your venture will depend. Of course, you will need a special glue, but the structure of the materials to be glued and the sequence of your actions in the process will play an important role.
Instruction
Not every glue is suitable for bonding metals. Therefore, carefully read the attached instructions or consult with. If, for example, you need to glue metal to rubber, then look for an adhesive suitable for both of these materials, and not just one of them.

Colorpolychloroprene adhesives - tan.
By Areas of use Polychloroprene adhesives are divided into two groups:
2.1. for rigid gluing(hard adhesive seam);
2.2. for flexible bonding(flexible, elastic glue line).
2.1. Polychloroprene (neoprene) adhesives for hard glue line - these are adhesives with relatively short molecular chains, the adhesive seam of these adhesives is quite rigid and durable. Adhesives have good adhesion to metals, glass, wood, stone.
They are mainly used for fastening to hard surfaces, to metal (including painted), wood, concrete, brick, plastered surfaces) materials such as rubber, textiles, carpet, linoleum, decorative elements, skirting boards, platbands.
To improve the bonding strength, the adhesive seam can be thermally activated (heated).
Polychloroprene adhesives that you can buy on our website are "Boat", "Moment Classic universal", "88", "88+", "88 Moment extra strong", "Stealth", "Avto Niva", "317", "Neoprene", "Super Cement", "Super Monolith".
Glue "88"- one of the most famous adhesives of this group, was developed back in Soviet time Institute of Aviation Materials. "88" glue is waterproof. Water resistance is achieved due to the fact that the composition includes synthetic resin.
It is used for gluing such materials: metal, rubber, wood, veneer, stone, parquet, tile, mosaic, ceramics, glass. For fastening various kinds coatings (including flexible ones) to almost any surface. They are used for lining the interiors of cars, buses, wagons, for the manufacture of seats. Very good for gluing synthetic upholstery materials to metal.

2.2. Polychloroprene (neoprene) adhesives for flexible, elastic adhesive seam with long molecular chains designed specifically for shoes ( "Nairit", "Shoe Nairit", "Shoemaker", "Leather").
"Nairit" is a special type of neoprene rubber with long molecular chains, specially developed back in Soviet times in Armenia*. This brand of rubber was given the name "Nairit". Now "nairite" refers to all adhesives made on the basis of nairite rubber, i.e. rubber with long molecular chains. When these molecules are connected, the seam remains flexible, which is very good in the manufacture and repair of shoes. If you take glue "88" - it has a very hard glue line. And in "Nairit" the seam is soft, elastic, flexible, it does not tear under loads, vibrations, it retains gluing. For shoes - perfect option! On our website you can buy a kind of glue "Nairit" - "Shoe Nairit".
* "Nairit" plant − one of the oldest chemical enterprises in Armenia. "Nairit", as a plant of synthetic rubbers "Glavkauchuk" named after. CM. Kirov, was established in 1936. The enterprise produced the demanded national economy chemical composition− calcium carbide. Since 1940, the plant has become a monopoly producer of chloroprene rubber. Until the end of the 80s, the plant occupied 10-12% of the world synthetic rubber market.
"Shoe Marathon Moment" – designed for gluing shoes and shoe materials made of rubber, thermoplastic elastomer, leather, leather substitutes, fabric, felt, cork, plastic in various combinations.

Designed to connect upper parts shoes made of natural and synthetic leather with rubber and leather soles, as well as for connecting shoe elements made of artificial leather, plastic leather, textile materials. It is also used when gluing coverings, linings, gluing insoles, reinforcing elements of shoes.
"Leather" – glue of increased elasticity and heat resistance for highly absorbent materials. For the manufacture and repair of products made of genuine and artificial leather, shoe uppers, fabrics, felt, synthetic materials, for attaching unshaped soles to shoe uppers.
Glue "Professional" Shoes-Leather-Rubber used for repairing shoe uppers, natural and artificial leather, rubber, fabrics, as well as repairing inflatable boats made of rubberized fabric.
Glue "Sprinter" is a universal fast-setting elastic adhesive for repairing shoes, including soles, leather, suede, nubuck, fur, polyurethane, PVC, rubber, fabrics. Can be used to bond any combination of rubber, leather, textiles, wood, metal, glass, wall tiles, ceramics and porcelain.
3. rubber adhesive It is a solution of synthetic rubber in gasoline. Previously, only natural natural rubber, extracted from the sap of the South American hevea tree, was used to make this glue, but now its synthetic counterparts are used.
Rubber adhesives that you can buy on our website - "Rubber" and "Latka"- used for gluing products that do not experience heavy loads.
"Rubber" glue- this is an inexpensive adhesive for non-critical joints. It is used for gluing rubber products that do not experience heavy loads. “Rubber” glue is very popular with tanners: the details of leather jackets and other products are first baited with rubber glue before stitching, and then stitched. It is elastic and can be easily torn. Residues of glue from the material are removed simply with gasoline.
Glue "Latka" for bicycle patches, it is used to “bait” the patches, which then still need to be vulcanized.
Also rubber adhesives are applied to pasting of products from a cardboard, paper, photos.
Gluing method these three groups are almost the same. Before gluing, almost any surface to be bonded must be sanded and degreased. First you need to apply glue, wait until the solvent evaporates so that only the rubber layer remains, and then press the surfaces to be glued and hold for some time under load.
Mode of application:
Apply an even layer of glue to the cleaned and degreased surface, dry to complete disappearance stickiness.
For responsible gluing, it is recommended to apply a second layer of glue after 10-15 minutes. after the first, also dry. The strength of the joint will increase by 1.5–2 times if the 2nd layer is heated to t ° \u003d 50–60 ° C.
Press firmly for 30 seconds. Crucial has the force, not the duration of the pressure. The product can be used after 1 hour. Final strength is achieved after 24 hours.
For polychloroprene adhesives, it is recommended to apply as much pressure as possible to the parts to be bonded. This is due to the fact that these adhesives are based on short molecules, and the stronger mechanical impact on the bonding surface, the better these molecules adhere to each other, i.e. better adhesion. There is also a recommendation - heat the seam, or thermally activate it. This is also done to improve the adhesion of the surfaces to be bonded.
In the composition of adhesiveswhich you can buy on our website, substances harmful to the body are not included, called precursors, which is confirmed by certificates of adhesive manufacturers. At the request of wholesale buyers, we enclose a photocopy of these certificates in the product packaging.
4. Cyanoacrylate adhesives, or "super glues"
Cyanoacrylate is organic matter, the molecules of which have the ability to very quickly combine with each other (polymerize). Super glues, or cyanoacrylate glues, cure within 1-2 minutes and provide a very strong bond.
Cyanoacrylate polymerizes under the influence of moisture, which is in the air. Therefore, if you want the glue to harden faster and the air is very dry, it is recommended to breathe on the gluing site.
Also, cyanoacrylate-based adhesive polymerizes rapidly under pressure. If, for example, cyanoacrylate glue is dropped on any surface, then the drop will remain liquid for a long time.
General instructions for use cyanoacrylate adhesives:
1. The surfaces to be bonded must be dry and clean. If necessary, clean from paint, dust, degrease.
2. Apply glue to one of the surfaces to be glued.
3. Press the surfaces firmly and hold for 1-2 minutes.
Colorcyanoacrylate adhesives - transparent.
Super glues are suitable for gluing the most various materials: metals, ceramics, porcelain, glass, precious stones, rubber, rubber, most plastics, elastomers, cardboard, paper, porous materials, PVC. Used for bonding any wooden materials. Suitable for MDF, chipboard, wood, plywood. They are used in the manufacture and repair of furniture.
By consistency super glues, which you will find on our website, can be divided into 2 groups:
Ordinary, liquid cyanoacrylate adhesives
"Super Moment", "Akfix 702", "Elephant",
"505", "Cyanopan E", "Cyanopan ME",
"Alteco 110", "Retainer 505"
· Super glues - " gel", "slow", thick cyanoacrylate adhesives. They do not spread, do not absorb as quickly as conventional super glues, they are convenient to apply on vertical, uneven, porous surfaces.
"Akfix 705", "Akfix 705 with activator",
"Super Moment Gel", "Alteco Gel", "Fixator Gel"
Special precautions must be taken when working with these adhesives. precautionary measures:
1. If in the process of working with glue your fingers accidentally stuck together - do not try to break them! Carefully and slowly separate them with a round object (such as a pen). After a while, the sebum itself will reject the remnants of the glue.
2. If the glue gets into your eyes, you need to immediately rinse them large quantity water and see a doctor. If glue gets inside, make sure that the airways are clear. Cyanoacrylate polymerizes (hardens) instantly in the mouth, making it nearly impossible to swallow. Saliva will gradually separate all the solid product.
4. Keep glue out of the reach of children!
5. Epoxy adhesives
On our website you can find two-component epoxy adhesives, creating a super-strong, hard surface, which, after hardening, does not shrink, does not deform. After hardening, it can be drilled, sharpened. Adhesives are waterproof, non-flammable.
