Properly selected glue for furniture significantly extends the life of the headset or its individual elements.
With this tool, you can restore damaged parts, improve appearance, to return the former functionality of cabinets, sofas, etc. In addition, the adhesive must meet the following requirements:
Another important parameter when buying an adhesive is its cost. For small jobs, you can purchase a more expensive option. However, high cost is not always a guarantee of adequate quality. V this case it is better to pay attention to the properties of the product, to choose the composition that is optimally suitable for a particular material.
quick-drying adhesive bonds wood surfaces instantly
There are several types of adhesive mixtures, which differ depending on the purpose. Each of them has high drying strength. A certain type of adhesive is selected, as a rule, by composition. Distinguish:
PVA glue is perfect for gluing foam rubber
When working with this type of material, you can not use any other type of adhesives, except for PVA. They can be not only ineffective, but also capable of damaging the surface. For example, liquid super glue instantly corrodes the fabric base.
uniform adhesive application on PVC sheet
According to the principle of hardening, all adhesives for furniture are divided into groups:
The last group of furniture adhesives according to the number of ingredients are divided into:
thermoplastic adhesive
Based on the origin of the main ingredient, there is:
Depending on the form of release on the market building materials The following types of adhesives are available:
Furniture adhesive containing a solvent (cyclohexane, acetone, hydrocarbon compounds, etc.) quickly hardens due to the evaporation of volatile substances. Water-based products require a longer bonding time.
for tight gluing of the surfaces of the bars, they are clamped with a clamp
To ensure maximum strength, reliability of joints, the adhesive seam must be made with a product with optimal composition. Ingredients should be selected taking into account the following parameters:
Technical parameters of thermoplastic adhesives for furniture:
Hot melt adhesive does not contain active (highly volatile) solvents. To firmly fix the surfaces, they must be pressed against each other, hold for some time (until the primary solidification of the adhesive joint). Reliability of pasting is provided with the resins which are a part, rosin, synthetic rubber. Some options contain a small amount of volatile solvents, which reduces the setting time of the mixture.
liquid glue in tubes for gluing fiberboard surfaces
Durable water-based adhesives sometimes require the treated surfaces to be placed under a press. This provides better bonding of the layers, increases the reliability of the adhesive seam.
The quality of bonding depends not only on the properties of the adhesive, but also on the correct preparation of the surface.
For example, porous materials such as plywood, wood, chipboard must be pre-dried and cleaned. A high percentage of moisture can increase the setting period of the furniture adhesive, reduce the strength of the adhesive joint.
Glue for furniture must be selected not only taking into account the type of material to be glued, the load exerted, external conditions. Do not forget about the ease of application.
applying adhesive to plywood boards
With development chemical industry the assortment, variety of adhesive mixtures is increasing. At the same time, the quality of popular and widely used furniture adhesives used for restoration and repair is improving.
when choosing glue for furniture, you should pay attention to the expiration date
You have probably noticed that furniture assembled from a thicker laminate looks more solid, in addition, thicker parts deform worse, which is especially important for countertops. But what if the plates desired thickness not on sale or you need only one part (for example, a tabletop) and buying a whole sheet for this is somehow unprofitable.
In such cases, they resort to fusion of chipboard in thickness. The essence of the method lies in gluing two or more sheets of laminate with cladding subsequently with a common edge.
For example, from 16 and 10 mm sheets it turns out 26 mm, from two 16 mm - 32. Please note that all sizes are standard (otherwise I once racked my brains - why exactly 32, and not 30)))
There are three main methods of fusion:
1. On self-tapping screws - it is used when one side of the resulting sheet is not visible or the heads of the self-tapping screws are masked, for example, by shelves. With it, two sheets, previously smeared with glue, are pulled together with self-tapping screws, twisted into countersunk holes drilled on one side. Because in this case, a slight displacement is very likely, then the parts are sawn 3-5 mm more required sizes and after the glue has dried, the milling cutter is brought to the right sizes and geometry.
2. The second option is to simply glue the blanks that are pulled together with clamps. In this case, the workpieces are sawn "to size", which means that it should be given Special attention prevent their displacement relative to each other.
3. The third option is economical and is usually used for. With it, strips of laminate left after sawing are glued to the lower (invisible) part of the table top. This method, along with increasing the strength of the product, makes it possible to make the most of the chipboard sheet.
After the glue dries (and, if necessary, refines the geometry of the ends), we select the groove for the edge, etc.
One of the most popular building materials is chipboard (chipboard). In practice, situations often occur when it is necessary to connect such plates to each other with planes using glue. This is done to increase strength. finished product or obtaining a part of the required thickness of small dimensions, without resorting to cutting a whole sheet of chipboard. How to glue chipboard ?, - it will certainly be interesting to know not only people involved in construction, furniture production or the manufacture of scenery, but also to any home master, in order to perform even better repair and restoration work.
The answer to the question "how to glue chipboard?" is not as simple as it might seem at first glance, because the boards to be glued can have different densities, surface treatments, humidity and moisture resistance. Of the variety of adhesives produced modern industry, glue is suitable for gluing chipboard:
For gluing chipboard, PVA glue, casein and other compounds of animal origin, resorcinol or urea-formaldehyde glues, as well as hot glue are suitable. But the most widely used in the performance of such work was PVA glue. For this purpose, the following types are best suited:
These adhesives can also be used to bond chipboard to wood, plywood, MDF or fiberboard. Their main advantages:
PVA glue forms a colorless seam when dried, which allows it to be used for surfaces of any color.
The most common case of gluing chipboard is the connection of sheets of this material or parts cut from it with planes. Most often, such a need arises, for example, when repairing furniture or making countertops. In order for the connection to be strong and reliable, you must adhere to the following rules:
To adhesive connection was durable, it is necessary to use only high-quality PVA glue, which you can order from our company ChMP "Concord"!
In this article, we will talk about how and with what to glue chipboard between themselves and other materials.
VIDEO INSTRUCTION
Never use modified PVA furniture or Titebond wood glue. Such types of glue are characterized by excessive capillary properties. They create voids inside uneven chipboard sheets, and this is fraught with poor bonding of materials.
Chipboard is often used to make kitchen worktops. Let's analyze the order of work.
For work you will need:
For the manufacture of countertops with a thickness of 28 millimeters or more, as a rule, several thin sheets of chipboard are glued together:
If you have a chipboard countertop ready and you just need to glue a few boards together:
All these details protect the countertop from mechanical damage, moisture and dirt. If the countertop is adjacent to the wall, you can glue a special skirting board that seals the joint and prevents debris from entering the cracks.
To securely fasten chipboard sheets for making furniture, glue must be applied in large quantities. Because of this, it very often protrudes from the seams and falls on the slabs.

Will PVA work or do you need something stronger?
Diamond Shark (2003-04-24 11:34)
Better than epoxy.
And even better in combination with mechanical fastening (screws, pins, etc.)

Yes, that's bad luck, the leg at the table broke - a chipboard board, thickness - 1.8 cm. I would like to connect it so that the fasteners are not noticeable.
MsGuns (2003-04-24 12:00)
If the chipboard is "torn out" at the point of breaking, then make an insert of wood ( beech is better- it has a texture without knots and is quite solid), and screw the leg to it with fasteners (not glue) such as corners. Then both metal and wood should be painted or sealed with a self-adhesive film "under the texture" of the table. The insert itself can be glued to a neatly processed recess in the chipboard with a simple PVA - a fairly strong glue. But for chipboard, wood glue or epoxy is generally better (the latter is expensive and somewhat difficult to use without special tools)

My cabinet maker uncle patched up potholes in chipboard like this.
Wetted the pothole with water for better adhesion.
Mixed PVA with sawdust thicker than this
porridge smeared voids. Fortress of the hardened mass
above the fortress of the chipboard itself. So next time
break down somewhere else.

Quite right, but not for areas where fasteners with a non-longitudinal load are located. For example, if chipboard with hinged loop for the door, then this method is enough to repair it, because the load is almost longitudinal, i.e. the force acts almost perpendicular to the chipboard surface or along the fastener (screw, bolt, nail). If, for example, a leg is attached to the plate, then the efforts will be somewhat or completely in a different direction (to the sides). Here the filler will quickly "break".
In any case, of course, at first it is desirable to see the "object" itself, or at least its schematic drawing.

Recently, more and more popular in the manufacture of furniture are corner connections plate materials with a bevel "on the mustache". In this article, our friend-colleague Sergey Novikov will share the secrets of making such a non-standard bar joint. Unlike a joint with an acute angle, which, firstly, is quite traumatic, and secondly, it is itself prone to chipping and deformation with minimal impact, this option is devoid of the above disadvantages.
So, first, by means of a tire, we saw down the mating edges at an angle of 45 degrees. In principle, this can also be done on a sawing machine, but a plunge-cut saw with a tire (2 passes) with respect to chipboard gives better results.
So, we get two parts with sharp corners, let's go directly to their connection.
To enhance the strength of the joint, we need a lamellar router (I think that you can get by with the usual one, but with special devices(So far, only vague outlines in my head).
Such flat furniture dowels (lamellas) are inserted into the grooves selected by the lamella.
They do not allow the parts to move during the displacement, and also add strength to the final connection, significantly increasing the bonding surface.
We coat the mating surfaces with glue (any PVA-containing adhesives will do).
We connect the parts and clamp with clamps until the glue dries completely. After removing the clamps, glue streaks remain on the corner - they can not be removed, because. later they will fall off on their own.
The next step is ‘this is the smoothing of the corner. It is carried out either with an angle cutter (45 degrees) or with a cylindrical cutter, but for this the router must have an angle base.
After cutting the corner, such a trapezoidal profile is obtained. Now our task is to ennoble this corner. You can, of course, just paint it or stick an edge, but the edge will not hold, and when painting it will not be possible to get a neat, even surface.
The cut must be patched. In this case, an automotive putty with fiberglass (which was on hand) is used, but it is better to use more homogeneous mixtures.
Degrease the putty surface.
The solution for this should not contain water. We apply the composition with a spatula, rubbing it into the pores and leveling.
After final drying, finally smooth the surface with a sanding block with fine sandpaper. Now let's color it in. Cheap spray paint will work for this.
We glue the edges of the cut with masking tape to protect the surface and cover it with paint 2-3 times. For additional durability and shine, open it with a layer of acrylic varnish.
We cut off the varnish streaks remaining after its final drying with a clerical knife. It seems to be nothing complicated, but the result is very interesting.

Carpentry. Mastery lessons.
The connection of parts made of chipboard (chipboard) causes certain difficulties. Since this material crumbles easily at the edges, carpentry joints are not suitable here, and additional parts made of wood or metal have to be used to ensure a strong connection.
One of the ways to obtain a strong and tight non-separable connection of parts is based on the use of screws and epoxy glue.
Screws are screwed into the end of one of the parts to be joined at a distance of 30-50 mm from one another. Under the screws, holes are pre-drilled with a diameter of 1-1.5 mm smaller than the diameter of the screw. The thread of the screws is lubricated with epoxy glue before screwing. Holes of such a diameter and depth are drilled in the second part in appropriate places so that the heads of the screws of the first part can easily enter them.
Now it remains to fill the holes in the second part with epoxy glue, generously smear the surfaces to be joined with the same glue, fold and compress the parts, providing a right angle between them. Excess glue must be removed and the knot must be kept for a day at room temperature.
It is convenient to make boxes in this way (for example, for acoustic systems) from polished chipboard, as well as from thick plywood or boards, since the method is simpler than studded and does not violate the decorative integrity of the material.
Veneering - gluing a product or parts of a wood product with veneer - thin, slender sheets of valuable wood.
All tears, potholes, pinches and dents on the veneered surface must be sealed with inserts using glue. The smallest of these defects can be puttied with adhesive putty. After sealing, the surface must be leveled and sanded. So that after gluing cracks do not form in the veneer, it is necessary, even during the preparation of the product, to close up (cover) all spiked joints and end surfaces with the help of planks, stickers or “kerchiefs”.
For large veneered areas, veneer with a large pattern is chosen, for small ones - with a small one. The veneer is cut according to a paper pattern with a sharpened shoe knife using a metal ruler. The cut pieces are sanded from the inside with a coarse-grained sandpaper and the cracks are puttied with adhesive putty. The prepared veneer, after aligning the edges, which should converge at the joints, is folded edge to edge according to the size of the veneered part and glued with paper tape 20-25 mm wide. In order for the edges of the veneer to be pulled together, the paper is impregnated with water before sticking, and when sticking, it is carefully smoothed.
Veneering is carried out in a room with an air temperature of 25-30°C.
The surface of the veneered part and inside The veneer is smeared with carpentry glue, and after 8-10 minutes the veneer is applied to the veneered surface and rubbed with a smooth bar or a flat carpentry hammer. It is good to grind the veneer with an iron heated to 50-60 ° C. Lap along the lines of the veneer texture from the middle to the edges. Emerging bubbles must be immediately eliminated, for which the veneer in the defective place is moistened with water, cut and glue is injected under it with a pipette or syringe, and then this place is smoothed with an iron.
Chips and tear-outs are patched by color and texture.
Dents are moistened and ironed with a hot iron until a smooth surface is obtained. After one and a half to two hours of drying at a temperature of 25-30 ° C, the paper strips that connected the pieces of veneer should be removed.

Chipboard tabletop
The modern furniture industry is gaining momentum. Many individual entrepreneurs try not to make kitchen sets, but to conclude contracts with the manufacturer and assemble ready-made modules. During the assembly process, there is a high probability of fitting the countertop in place and you have to resort to glue.
In order to understand the diversity, we will carry out short review varieties of adhesive edges and glue for various countertops.
This is the most common material in furniture production. In the process of cutting, the edges of chipboard require additional processing to give them an aesthetic appearance and protection from moisture. There are several types edging tape with an adhesive base, intended for finishing the ends of the table top:
Acrylic edge 3D
Laminated chipboard has a different thickness, according to its dimensions, and the edge with glue for the countertop is selected. The most popular is PVC strip, which is available in the same color as chipboard.
Gluing tabletops artificial stone
Quartz composite is considered the most durable and strong material. From small crumbs natural stone and polymer resin are made durable wear-resistant countertops. They are resistant to moisture, high temperatures and various aggressive substances.
Thanks to the application modern technologies the performance of artificial and natural stone is equal. Beautiful appearance retains the natural pattern of quartz. The surface is resistant to mechanical damage and UV rays. long time retains its original shape and color.
For installation on a prefabricated kitchen unit, the countertops are supplied as a full size slab, which is fitted in place and secured with adhesive. For reliable and high-quality gluing, adhesive compositions are used on acrylic base.
The main advantages of the acrylic component are:
Acrylic adhesive for stone is widely used in restoration work. With its help, chips and small potholes are poured on stone slabs. After full rise and polishing, these places become invisible and acquire their original appearance.
artificial countertop
Good strength and magnificent appearance of artificial stone were the reason for widespread use it in the manufacture of countertops. However, they do not have sufficient strength and are subject to mechanical damage. To carry out restoration work, first of all, you will need glue to repair artificial stone countertops.
Depending on the composition of the countertop, be it concrete, lime mortars or clay brick, a restoration adhesive mixture is selected. When choosing, first of all pay attention to tinting. The color of the work surface and the glue must be identical, otherwise the restored stains will be striking and the aesthetics of the countertop will be disturbed.
Diversity color palette adhesive composition will not provide difficulty in choosing.
Most repair adhesives artificial countertops in their composition have white cement with polymeric additives. They have good strength characteristics and high moisture resistance. White color the mixture is well tinted, therefore, you can easily choose the desired tone. You can see the restoration methods in the video.
For gluing countertops made of artificial stone, an adhesive consisting of two components is used: an acrylic-based polymer and a hardener. Before application, the components are mixed in a certain proportion indicated on the instructions for use. The main thing is that it is necessary to breed not the entire volume, but only required amount, as the unused mixture will dry quickly and will be unsuitable for further use.
