In this article we will consider the question of how to glue wood to concrete. Sooner or later, many people who start repairs in an apartment or in a house face the problem of connecting these materials.

The need for gluing such materials occurs when a wooden floor covering is laid on a bare concrete screed or skirting boards are installed with their own hands, wooden fillets are mounted, etc. However, sometimes fasteners are needed for more solid and weighty items, and this turns into additional difficulties.

Fixing Methods

Over the long history of construction works has been tested a large number of ways of fastening wood to concrete. Among the actual and widely used methods, we note the use of specialized mounting adhesives and the use of fasteners.

Consider the features of the implementation of these methods and find out what materials are optimal for such work.

Application of specialized adhesives

If reinforced concrete was cut with diamond wheels, and now it is necessary to mount wooden parts that are small in size and weight, you can use special mounting adhesives.

Properly selected adhesive composition allows you to securely fix not only baguettes or skirting boards, but also linings on stair steps. However, you need to understand that the range of adhesives is wide, and therefore you should count on the best result only if correct selection funds.

If you need glue for concrete and wood, pay attention to the following compositions:

• Construction adhesive "Liquid nails" It is relatively inexpensive and at the same time effective solution to work with materials of interest to us. "Liquid nails" and are presented on the market in several modifications, namely, "Universal", "Express", "Super strong", "Especially strong", "For panels", etc.

If the question is how to attach wooden block against a concrete wall the best choice will become a particularly vicious and universal modification.

The universal type of glue "Liquid Nails" is an excellent choice for interior applications. For example, with this tool, you can successfully glue lumber wall panels to pre-fabricated.

But if you are interested, then how to glue wood to concrete with sub-zero temperatures, you will need "Liquid Nails" especially strong with a setting force of up to 70 kg per 1 m². This adhesive will hold wood even on uneven concrete at temperatures down to -17°C.

• Glue "Moment"- This is a wide range of different compositions with different technical and operational properties.

In the photo - the two-component composition "Epoxilin Duo"

Of particular interest is the Epoxylin modification, which is a two-component composition that works with a wide range of materials including concrete and wood.

After drying, the composition not only reliably holds the glued surfaces, but can also be sanded or subjected to other machining without compromising the adhesion strength.

Another modification of the Moment glue, through which concrete can be connected to wood, is Moment Joiner. This tool has found wide application in the process of laying floor coverings made using lumber.

Mounting foam is a good option for simple and effective gluing

In the photo - the use of mounting foam

If necessary, as an adhesive, you can apply mounting foam increased strength. It is a good solution for flooring flooring. wood flooring, installation of window sills, wall panels, etc.

This method of connecting two surfaces is characterized by a number of advantages, including:

• affordable price, in comparison with other adhesives;
• high bond strength after complete drying of the composition;
• low degree of thermal conductivity, which is important when finishing floors and walls;
• excellent soundproof qualities;
• hydrophobicity;
• biological stability;
• simple instructions for use.

However, there is also a significant drawback, namely the long drying of the foam. Therefore, within 5 minutes, the glued part will have to be held in the desired position so that it does not move away from the surface.

Important: In order to ensure optimal contact between the surfaces to be bonded and the foam, they must be lightly moistened with water.

Surface preparation is the key to success

Whichever of the above compositions you choose, before attaching wood to concrete, both surfaces must be properly prepared. In order for the result of the installation work to be a strong and durable connection, both surfaces must be as smooth as possible, free of dust and grease.

The main problem is the porous structure of the material, especially if diamond drilling has been carried out in concrete. This property is the cause of excessive absorption of adhesives, and therefore the connection does not have time to gain proper strength.

It is not difficult to make a coating prone to gluing from concrete, for this you need to reduce the number of pores. For this, deep penetration primers are used, which seep into the porous structure of the material and solidify there. As a result, the micropores are closed, and the density of the concrete allows the application of adhesive.

Important: Glue wooden parts to pre-prepared concrete bases in strict accordance with the instructions of the manufacturer of adhesives.

Fasteners using dowels

If you need high-quality and durable fastening of a wooden pole to concrete, ordinary glue or foam is indispensable. In this case, you can use fasteners hardware designed for high mechanical loads.

Heavy wooden parts can be attached using dowel-nails and anchor bolts. The principle of operation of these fasteners is similar, since after they enter the concrete, their working part begins to burst. As a result, the fastening of wooden poles to a concrete base is very strong.

Conclusion

There are many ways to reliably connect concrete surfaces with wooden details, but maximum strength will be guaranteed if pre-treatment is carried out. There is no need for a connection using dowels.

To date, there are many floor coverings, however, the tree that has been tested for centuries has not lost its relevance, and is still very popular. As a result, many homeowners decide to mount wood planks over concrete screed. This procedure is not too complicated, but requires certain knowledge, therefore, below we will take a closer look at how a wooden floor is installed over concrete.

Mounting wooden planks

General information

Often, before performing repairs, people think about which floors are better - wooden or concrete?

At first glance, concrete floors may seem more practical for the following reasons:

• They do not rot, resulting in more durable;
• Over time, they do not begin to creak, unlike a wooden floor;
• They have good durability.
• Moisture resistant, etc.

However, it is no secret that a concrete floor is colder than a wooden one and, of course, less comfortable. As for the disadvantages of the boardwalk, such as the tendency to rot or loosen and creak, then, subject to modern technologies installation, they cease to be a problem.

Therefore, when deciding which floor to lay - concrete or wood, you should take into account the conditions of its operation. For example, in the bathroom or in the kitchen it is more appropriate to use a concrete screed covered, for example, tiles. But in the hall or bedroom, where comfort and coziness come first, it is more expedient to cover the floor with wood.

Technology of laying a wooden floor on concrete

Now let's take a closer look at how to lay a wooden floor on a concrete base.

It should be said right away that there are several installation technologies:

• Bonding boards to concrete;
• Laying on logs;
• Laying on plywood;

To choose the right technology, you should familiarize yourself with each, what would we do next.

Leveling concrete with self-leveling mortar

Foundation preparation

Before laying a wooden floor on concrete, you need to prepare the base, regardless of which installation technology will be used. Preparation consists in drying the screed, if the floor was recently poured, and leveling. If the surface of the base has bumps, then they can be removed by grinding, if there are “pits”, then such a flaw is easiest to eliminate with a self-leveling mixture.

Note! Proceed to installation work only possible if the moisture content of the screed does not exceed 3 percent.

At this stage, it is also necessary to make holes in the concrete for conducting communications, for example, sewer or water pipes, cables, etc. Most effective way is diamond drilling of holes in concrete.

If the area of ​​\u200b\u200bthe room is large, then in a freshly poured screed, expansion joints. For these purposes, reinforced concrete is cut with diamond wheels. The final step in preparing the base is to coat the surface with a primer.

The impregnation will serve as a waterproofing, and will also prevent the occurrence of fungus and mold under the wooden floor. As a primer, a polyurethane one-component primer mixture is usually used. After the primer dries, you can proceed with the installation of the floor with your own hands.

Bonding boards to concrete floor

Adhesive laying

This technology consists in mounting the boards directly on the concrete base. Recently, it is the most common way of laying wooden boards on a screed.

True, installation can only be started if the base complies with SNiP 3.04.01-87. If the concrete is friable or contains cracks, it is necessary to use special reinforcing soils or cover it with a separating substrate, for example - Multimoll Vlies.

If laying wide massive board, then a modified elastic one-component polyurethane adhesive is used for gluing the boards. The installation of a narrow solid or engineered board is carried out using a two-component polyurethane adhesive.

Polyurethane adhesive

The device of a wooden floor on concrete in this case is as follows:

• First of all, you need to measure the room and cut the boards of the required length.
• Then, starting from the wall opposite from the entrance, glue is applied to the surface of the base and leveled with a notched trowel. The layer thickness should be no more than 3 mm.
• Next, a board is laid on the surface covered with glue and pressed over the entire area.. In this way, 2-3 rows of boards are mounted. When laying boards, they must be tightly joined in the longitudinal and transverse directions, for this you can use tie-down straps or wedges.
• After polymerization of the glue, the rest of the boards are laid.. In this case, the boards of the last row must be cut in width.

Note! A gap of at least 15 mm must be left between the walls and the coating.

Installation of the floor on the logs

This technology involves the installation of boards to wooden lags(rectangular bars). It can be used for boards with a thickness of 20 mm. Thinner boards should only be mounted on plywood.

The installation instructions are as follows:

• Logs are attached to the concrete floor with dowels and screws. At the same time, their hats should be recessed a few millimeters below the surface level. The axial distance between the lags should be 25-30 cm.

I must say that there is another way of attaching the lag - to adhesive and bitumen-containing mastics. This technology is justified if, when drilling concrete, there is a possibility of damaging communications.

• After installing the lag, it is necessary to align them according to the level. Places that protrude above the level must be removed with a planer. As a result, the deviation from the level should be no more than 2 mm per two meters.

Scheme of mounting a wooden floor on logs

• Further along the walls you need to lay soft fiber boards, which will serve as a soundproof gasket between the floor and the wall.
• It is desirable to fill the space between the lags heat-insulating material, for example, expanded clay or mineral mats.
• After that, the installation of boards is carried out, which are attached to the logs with self-tapping screws. Of course, nails can also be used for these purposes, but over time, such a mount begins to loosen, as a result of which a characteristic creak appears when moving across the floor.

This technology is good because it allows you to conduct communications under the floor, as well as use insulation. However, the price of the structure increases, since in addition to the boards it is necessary to purchase more bars.

Laying on plywood

wooden floor on concrete base can be laid with moisture resistant plywood 12-18 mm thick.

In this case, the procedure is as follows:

• Standard sheets of plywood need to be cut into squares measuring 40x40 cm or 80x80 cm.
• The resulting fragments are stacked diagonally towards the future coating. Moreover, the gap between them should be about 4 mm. Plywood is first glued, and then shot with dowels.

A distance of about 10 mm must be left between the edges of the plywood and the walls. The sheets are stacked with an offset according to the principle of brick luggage, while the screw heads must be sunk by 3-4 mm.

• Before laying plywood on a concrete floor, it is rough sanded.
• The leveled base should be free of dust.
• Then the boards are attached to the plywood using self-tapping screws.

That's all the highlights of installing a wooden floor over a screed. It must be said that in some cases it is necessary to perform the operation in reverse, i.e. pour concrete over wood floor. Most often, in this case, a concrete screed is performed on wooden logs.

Sanding plywood

To do this, metal corners are attached to the side walls of the log, on which a reinforcing mesh is laid, while the space between the logs is covered with expanded clay. After that, the concrete mixture is poured, which should be above the lag level.

This technology is used in old apartments, in which the floors between floors are wooden beams.

Laying a wooden floor over a screed is an affordable operation that anyone can perform. House master. The only thing is that it is necessary to strictly observe the installation technology, and do the work very carefully and accurately. In this case, the floor will turn out to be strong, even and durable (see also the article “Fastening wood to concrete: the main methods and features of their implementation”).

See the video in this article for more information on this topic.

You can glue materials of various compositions, you just need to choose the right adhesive base. It would seem that it is possible to connect concrete and metal, or attach glass to it, but this is done with the help of special adhesive solutions and tools. During the construction of houses and their subsequent finishing, it is supposed to be glued to concrete various surfaces, including concrete to concrete, and sometimes not only the decorative part, but also the stability of the walls of the room depends on the reliability of their adhesion.

How to glue concrete together

During the construction process, there are moments at which it becomes necessary to glue together concrete structures. Concrete - fake diamond, which can be glued with epoxy or furyl adhesives.

For structural rigidity, it is knocked down from old concrete upper layer, and then carefully cleaned, also small particles of dust and debris are removed from its surface and a portion of the composition containing glue and hardener is applied. It is distributed over the bonding surface with a spatula or brush and a new concrete structure is immediately laid on it. For its bonding, resin compounds are used, which are used in the cold method.

Choice of binder with plastic as well as plastic and PVC panels

For gluing the latter to a concrete surface, the multi-purpose Moment Germent is well suited, which can glue these two surfaces with high quality.

Plastic with concrete is connected with the usual construction adhesive "Titan", which has excellent adhesion and moisture resistance.

Also, Liquid Nails are well suited for gluing plastic surfaces with cement. This adhesive can be purchased as a dry mix, which consists of cement and polymers.

For a secure connection between two different designs it is necessary to clean the concrete surface, putty and level it, otherwise smooth plastic surface won't come. PVC panels are pressed against the concrete plane with building level and aligned along the entire length, the adjustment of their location can be carried out within an hour. The glue will fully harden in only three days.

In construction, it will not be superfluous to know about

Wood, laminate, plywood, parquet and sandwich panels

Modern adhesive materials allow bonding with concrete even wooden surfaces. Before carrying out this work, it is necessary to prepare the cement surface and walk on it with a special primer, which will protect the joints from the accumulation of dirt and moisture in the future.

To parquet board was securely fixed to the floor using epoxy or polyurethane adhesive. The latter consists of a hardener, solvent and filler. It comes in both solid and liquid state. It is most often used in the form of a liquid quick-setting mastic. It has good hermetic and electrical insulating properties, but with sudden changes in the air in the room, it is better to replace it with epoxy glue.

Ruberoid

At the beginning of construction, literally at the final stage of foundation construction, the question arises of its sealing, which roofing material can provide. It is attached to concrete with bituminous mastic. It is applied with a roller on the cement surface. Then, together with the roofing material, it is heated for better adhesion and glued, placing improvised loads on top.

metal with stone

Even such incompatible materials can be glued. A two-component epoxy composition can act as their reliable binder. It contains:

• mixture epoxy resin with filler and plasticizer;
• combination of thixotropic additive and hardener.

New technologies make it possible to fasten seemingly incompatible materials. When carrying out the gluing process, it is necessary to carefully prepare the working surfaces and choose the adhesive that is suitable in composition. Some of its types can only be used for internal works while others serve well in hostile environments. Compliance with the order of work and right choice materials will guarantee excellent results.
