Installation of moisture-resistant tongue-and-groove chipboard on the floor: Review + Video

Installation of moisture-resistant tongue-and-groove chipboard on the floor. All the latest building materials are quickly conquering the market, and laminates and various beautiful slabs will surprise few people. And chipboard is far from the newest popular material that can be used for flooring, but at the moment a new product has appeared on the construction market - tongue-and-groove chipboard, moisture resistant, and it is used for the floor as a leveling material.

Let's take a closer look at it and learn how to use it correctly, as well as how to work with it.

General information

Moisture-resistant and grooved chipboard for the floor

If deciphered, then chipboard is a wood particle board, and it is a material that has been used for construction for many decades.

It is also used to make furniture and is sometimes used for other purposes. For this reason, it cannot be called a completely new material on the construction market. But the standard chipboard has some drawbacks that limit the scope of application, because such a board does not like moisture very much, it can begin to swell under its influence, even despite its high strength and density. But progress and science are moving, they do not stand still, so now engineers are able to make this type of chipboard that is not afraid of moisture.

Tiled chipboard moisture resistant is a real find for those who want to level the floors quickly, without the appearance of gaps between individual elements, to get a base that will not be afraid of water.

The difference between this chipboard and the standard one is that during the manufacture of the raw materials, special components and compositions are added, which can provide that very protection from water. For example, it can be paraffin emulsions. In general, during production, waste from wood processing is used (shavings from inexpensive hardwood and coniferous wood), as well as resins that connect them to each other. The process of creating plates takes place under the influence of high temperature, as well as high pressure.

Good advice! To distinguish moisture resistant chipboard from standard, it will be enough to look at the color coating of the material.

The moisture-resistant material on the surface will have inclusions of green, even emerald color, but if you wet such a chipboard completely and leave it in the form for a long time, the plate will start to spoil and still swell.

Grooved chipboard has a special type of connectors - on one side such a plate has a thorn, and on the second a groove for a thorn. When several slabs are laid in a single row, they will be joined together and firmly connected precisely thanks to this technology, which is simply called "thorn-groove".

Take note, that usually moisture-resistant chipboard is tongue-and-groove on each side, that is, on each end there will be either a spike or a groove, and this will help ensure not only the connection of vertical, but also horizontal rows of plates among themselves.This will make it possible to simplify and speed up the entire installation process.

Usually such a board is marked as B, and this means "moisture resistant". Chipboard even has classes - P3 and P6, which are suitable for rooms where the humidity level is low or medium, but the P5 class is suitable for those rooms where the humidity level is very high. Chipboard can also be divided into several varieties, everything will depend on the number of layers - single-layer, three-layer or multi-layer. Most often, it is the last type of plates that are used, with a large number of layers. Small and coarse shavings will be used to create them, in addition, the outer layers are made from smaller components.

The dimensions of the slabs are usually 2.44 * 0.6 meters or 1.83 * 0. 6 meters.

In this case, the thickness of the products will be equal to either 1.6 cm or 2. 2 cm. Moisture-resistant grooved boards are made from wood chips, which are mixed with thermosetting resins.

Advantages of grooved slabs

Grooved chipboard moisture resistant for floor installation is not in vain so popular in the construction industry, as it has many advantages.

It makes it possible to use itself for various purposes, and laying the sub floor can also be attributed here. The advantages of moisture resistant chipboard with tongue and groove are described below.

1. To begin with, it is possible to resist the action of water. If we compare such material with OSB or plywood, then DP has the maximum resistance to moisture. Even if you leave such a tile in water for a day, it will increase in size, but to a maximum of 1/10 of the original volume.

   In addition, it does not deform or bend.

2. Sustainability . An additional and equally useful quality. Yes, the stove is made using polymer resins, but in general it is not a source of harmful substances if it is used correctly. Particleboard is allowed to be used even by an educational institution where children will be trained, or in places to which special sanitary requirements are imposed.

   Particleboard is recognized as the most environmentally friendly among all similar materials with the same characteristics.

3. Uncommon Durability . Moisture-resistant chipboard with tongue-and-groove piles will not break, will not bend, and can withstand great pressure without damage to itself. Even with the strongest point loads, the foundation will not be a problem.

4. Easy to install and assemble .

   If necessary, it will not be difficult to cut the slab with a hacksaw or an electric jigsaw, which will be especially useful in those moments when it is necessary to carry out repairs or even replace the coating. Also, the presence of the "thorn-groove" system makes it possible to reliably connect individual plates into a single durable coating, since they will simply and reliably snap together, and there will not even be any gaps between them (provided that the installation is done correctly). Also, you will not need to use unusual and rare tools to complete all the work, since everything you need will be at hand at the zealous owners.In addition, chipboards are lightweight, which greatly helps to simplify the work process. The weight of one sheet, the thickness of which is 1.

   6 cm, is not more than 15 kg. If a moisture-resistant tongue-and-groove chipboard is used for the subfloor, then it will not be necessary to additionally level the floors with a cement screed, which will be a considerable savings.

5. Long service life is achieved due to the fact that moisture-resistant tongue-and-groove material is not afraid of rot and mold.
6. Low cost. Even if we compare it with ordinary plywood, then such material is several times cheaper, which means that it is more affordable.

7. Huge application possibilities. Moisture-resistant tongue-and-groove chipboard is perfect not only for making flooring, but also for most other purposes.
8. Sound and heat insulation performance is excellent. Particleboard will do an excellent job of blocking out noise and heat from neighbors. She will not let heat out of the house, and she will not let unnecessary sounds into the house.

9. Chipboard makes it possible to create a perfectly flat base without additional costs. In addition, no special coating is required for the installation of the finishing coat.
10. Chipboard can be easily dismantled and re-installed, and this makes it possible to carry out repair work on the base of the floor if necessary without unnecessary problems and even more attracting professionals.

Please note, that it is not at all necessary to cover the chipboard layer with finishing material, since this is not a residential area. If there are no special requirements for the interior decoration of the building, then the moisture-resistant tongue-and-groove chipboard for floor installation can simply be covered with a layer of paint, and there will be a finished floor.

Before making a final decision on buying a material such as moisture resistant chipboard, you should also find out about all the shortcomings of the material, namely:

• Do not use chipboard for assembly work on strongly curved surfaces.
• The sawn ends of the material must be treated with special agents that protect against moisture.
• It is undesirable to lay chipboard in those houses where people who suffer from allergies live, since the surface of the coating will still emit formaldehyde, even in small doses. Processing of ends with cuts is also required in order to reduce the amount of substances released into the environment, which can have a negative effect on the body as a whole.

Now it's worth talking about the functions of the material.

Multifunctionality of grooved boards

Chipboard boards - both standard and grooved, can be used for premises with different areas of purpose:

• Residential - in houses and apartments.
• Offices, administrative buildings.
• At enterprises.
• In buildings that are used for public purposes (shopping centers, complexes, galleries, etc.).

In apartments, however, moisture-resistant chipboard is used in any room - in the hall and bedroom, bathroom, toilet, in the kitchen, etc. Due to the fact that the material is able to perfectly transfer moisture, they are sometimes even laid on the balcony and loggias, which are often not particularly isolated from the effects of weather factors. Chipboard is able to feel great and not lose its quality even in a poorly heated room.

In general, tongue-and-groove chipboard boards are ideal for arranging a rough floor. They perfectly cope with the task of leveling the base, so that afterwards you can install any type of coating, be it parquet, tile or laminate.

Moisture-resistant chipboard is excellent for leveling walls and is installed under the finishing of the room. Various interior partitions are very often made from it.

Please note, that suspended ceilings, despite the fact that stretch ceilings are very fashionable, also remain in trend. And from chipboard, you can get excellent ceiling structures, which will be much easier to install than drywall sheets.

Another purpose of using such a material will be to create formwork during the pouring of the foundation for the house.

It can be easily mounted and removed as easy as installing.

The popularity of tongue-and-groove type joints

Not standard, namely, moisture-resistant tongue-and-groove chipboards for floor installation have been able to gain incredible popularity. This is due to the fact that it eats the "tenon-groove" system, which makes it possible to create the maximum solid and monolithic base. Due to the fact that there will be no gaps between the slabs, the subfloor is very durable. This is especially so if the joints of the slabs are glued with special glue - in this case, the structure will be as tight as possible and no waterproofing will be required.

Another goal can be achieved due to the tongue-and-groove - even distribution of the load throughout the floor. And this type of connection is many times stronger and more reliable than between plywood sheets nailed to the floor.

How to make the right choice

When choosing a moisture-resistant tongue-and-groove chipboard, you should pay attention to the main characteristics of the material so that no mistakes are made. Otherwise, the coating will not be strong enough and will begin to deteriorate quickly.

What you should pay attention to:

• Flexural strength (should be from 10 to 25 MPa).

• Tensile strength (from 0.2 to 0.5 MPa).
• Propensity to swell when exposed to liquid (5 to 30%).

In addition, it is better to try to pick up thicker slabs - at least three-layer, and even better those that consist of five layers.

It is also important to pay attention to the selection of the manufacturing company (and to stop the choice is the one that will hold a strong position in the building materials market for many years), as well as the brand of products. For the floor, it is better to buy a moisture-resistant tongue-and-groove chipboard.

Variants of laying a floor made of grooved chipboard

Installation of a rough base made of grooved chipboard can be done in two ways - standard and floating. In the first case, various materials are first laid on the floor in order to provide waterproofing, and then logs can be installed, and a layer of heat-insulating material can be laid between them. Only after that it will be possible to carry out the installation of the plates themselves using an adhesive composition.

Also, the plates need to be additionally attached using self-tapping screws.

Chipboard can also be installed in the second way, floating, when the boards are simply not fixed to the surface of the base. They are laid on insulation or a layer of sand cushion, and then connected together. Such floors can be considered more durable and can be called a kind of dry screed.

Installation of a floor made of waterproof material.

For this type of work, you need the following:

• Insulation layer.
• Chipboard boards.
• Lag bar.
• Roulette.
• Waterproofing material.

• Mounting adhesive for chipboard.
• Building level.
• PVA construction waterproof.
• Self-tapping screws.
• Rotary hammer, screwdriver.

Now the instruction itself:

1. Moisture-resistant tongue-and-groove chipboards should be brought and placed in a room where they will be laid afterwards. They should be left for two days, since 48 hours in order for them to adapt to the microclimate of the room. This is especially important if the material was transported in the winter.
2. Next, on the rough covering, which is free of debris, we lay a layer of waterproofing film with an overlap on the walls. After that, the beams-lags should be installed, the step should be no more than 0.

   3-0. 4 meters, provided that you are using boards with a thickness of 1.6 cm. For thicker materials, you can take a step to install the logs of about 0.6 meters.

3. If, for some reason, the step between the lags is greater, then a crate of boards should be made perpendicular to the lags.
4. When everything is ready, fill the distance between the logs with a layer of insulation, for example, mineral wool (you can use another one of your choice). In this case, the layer of material for insulation should be 3 cm lower than we assume the level of the subfloor.
5. After that, apply assembly glue to the edge of the lag, and treat it with waterproof PVA D-3 building glue into the tongue of each plate. The latter procedure will help create excellent water resistance.

6. We lay the boards on the logs and press them so that the glue previously applied to the edges is neatly distributed over the surface of the log.The slab should be mounted with the long side perpendicular to the laid joists. Along the perimeter of the room, it should be fixed with self-tapping screws on the logs, and the step should be 0.2 meters. It is important that there is a gap of 1 cm between the walls and the slabs.

7. Next, lay the next slab. The connection of individual elements is carried out according to the same "tongue-and-groove" fastening system.
8. Remains of building PVA glue, which appeared at the junction of two boards, should be removed with a soft cloth. All joints of the slabs must necessarily be on the logs, but if the joint is located between the logs, then you will need to make an additional supporting jumper. It should be installed necessarily perpendicular to the lags.

9. The joints between the boards should be additionally hidden with a sealant or a special mastic that can be used for wood coverings.

To reduce the amount of waste, it will be enough to use large pieces of slabs to start the installation of a row. The main thing is that a piece of the slab rests on at least 3 logs, that is, it can cover 2 spans at a time. It will be possible to move on such a floor already after a day, since this is how much time is required for the glue to freeze.

Moisture-resistant tongue-and-groove chipboard for floor installation can become an excellent rough (and sometimes even finishing) base, so that after finishing the floor is laid.

Its installation is simple, but on the contrary, very easy and simple, does not require special skills from the master. Therefore, after studying the instructions, any person can install such a floor.
