Preparation of concrete floor for laminate flooring - stages, video

Laminate is often used as a floorcover. Externally, these are narrow panels that are made on the basis of wood residues, a decorative layer and a protective coating are applied on top, which gives the material unique properties. Laying laminate flooring is simple, almost everyone can handle the job. The most responsible process is the right one. Layout of the laminate. What are the preparatory works? Laminate is a board, for laying which is important an even and solid base, otherwise it will start to crack, locks are deformed. All this will lead to the fact that individual lamellas have to be changed, the floor itself will creak when walking, claps will be heard. The service life of the coating will be reduced, and the use of special pleasure will not deliver. To exclude all the incidents, without the preparation of a foundation under the laminate is indispensable. It includes the dismantling of the old coating, the alignment of the base base and the laying of a special substrate in the form of an amortization material. Preparation of the base can not be neglected, otherwise the floor covering will lose all its positive characteristics.

Alignment of concrete base

Preparation of a concrete floor for a laminate includesfilling the screed. This "wet" construction process, which will take a long time, for the final drying of the foundation will take about a month. To perform the work you need to prepare: Scheme of cement floor screed.

• cement-sand mixture in dry form;
• water for pouring the mixture;
• mixing tank;
• drill, nozzle mixer;
• lighthouses;
• rule;
• building level.

The alignment process itself includes the following steps:

First you need to remove the old floor covering, inspect the condition of the floor. All cracks and potholes are filled with cement or putty, and the protruding parts are grinded by the Bulgarian.

The surface is primed and primed. The mixture is kneaded in small portions, the pouring is performed from the far corner of the room, distributed by the rule according to predetermined beacons.

Attention should be given to the joints between the individual sections, they must be carefully leveled.

When the floor is completely filled, it is necessary to leave it for about 28 days to dry. The next step is laying the substrate, the most laminate coating.

Aligning the wooden base

Preparing the wooden base is donemuch easier than concrete floors. So-called wet processes are not used here. For alignment, sheets of plywood, particle board, and OSB are used. The base is prepared in this way: The scheme of leveling the floor with a moisture-proof plywood.

First remove the old coating, after which the surface should be carefully inspected. If there are cracks, rotten boards and other damage, the floor should be repaired.

After that, plywood slabs (namely they are used most often) are to be cut into small squares and laid on the floor.

The plywood is laid with millimetric gaps in a staggered order, it is fixed to the base with self-tapping screws.

If the floor is very uneven,to establish logs, and plywood will be laid on them. During the preparation, the base can be insulated, for this purpose, lime is poured between the lags, or mineral wool is laid. To do this work, you should prepare:

• plywood plates;
• beams for logs;
• self-tapping screws;
• building level;
• electric jigsaw;
• heater;
• screwdriver.

Use of leveling mixtures

Floor preparation for laminate can be carried out withusing special leveling, i.e. self-leveling mixtures. For laying, beacons are necessarily used, they are made from a regular rail or rule. Lighthouses can be easily made by yourself, although there are ready-made slats for working with floors on sale. To complete, you need to prepare: Scheme of leveling the floor with a self-leveling mixture.

• leveling mixture;
• capacity of 20 liters;
• rule;
• special needle roller;
• a mixer and a drill;
• beacons of the chosen type;
• shoes with thorns.

The technology of preparation of the base is simple. First, remove the old coating and inspect the surface. Cracks and potholes fill with a solution based on cement or putty. When the substrate dries, you can proceed with the alignment of the substrate. For this, a dry mixture is filled in the container, it is filled with water strictly according to the instructions. Mix the mass with a mixer until uniform. Further, beacons are exposed to the floor and a fill is made from the far corner of the room. The mixture is rolled with a needle roller, it is possible to walk on the surface of the base only in special studded shoes. After pouring, it should take about an hour and a half. If there are unevennesses, then they are removed by the rule. When the substrate is primed with a self-leveling compound, the following conditions must be observed:

The technology of preparation of the leveling mixture must exactly correspond to the recommendations of the manufacturer, it can not be made too thick or liquid.

To avoid pits after the pouring, it is necessary to roll out each section in addition, since the composition is rather fluid.

During the pouring of individual areas, irregularities may appear, but they are easily removed by the rule, do not neglect such a step.

If beacons are made from a solution, then all their protruding parts are ground after casting. Metal profiles are removed, the cavities are filled with a mixture.

Laying of the substrate under the laminate

Laying the film floor under the laminate. During the preparation of the substrate, one should not forget about the use of a cushioning substrate. This is a special thin material that allows you to extend the life of the coating. It acts as a soundproofing pad, allowing the load to be properly distributed to the surface of the board. Today, there are a lot of such substrates, but experts identify 3 main ones:

• cork floors;
• foamed polyethylene substrates;
• expanded polystyrene.

Cork substrates are a natural material withexcellent characteristics. It has a preventive and even curative effect, it is shown to be used if people with diseases of the musculoskeletal system live in the house. The cork of the cork is expensive, although its quality is the best. It is made in the form of plates or coils, in some cases this material is combined with bitumen or rubber. During the load, the web does not lose its shape, it makes it possible to disguise small irregularities. Layout of the substrate under the laminate. But the cork is afraid of humidity, therefore, waterproofing films should be used. The laying is simple, the floor is glued to the floor or the building scotch is used to fix the individual elements. Foam-polyethylene substrates are a foamed material that has many advantages, including resistance to mold, fungi, moisture, chemicals. The base must be carefully leveled, and the durability of this material is not too high. Laying the substrate of foam polyethylene is simple, it comes in convenient rolls. On the base it is applied with an overlap, individual strips are glued together with adhesive tape. After laying the laminate, all the excess that will protrude on the wall surface is cut off. Styrofoam provides proper sound insulation, fits very simply, but eventually loses its shape. Experts believe that this substrate is universal, can be used for any occasion. Its laying is similar to the previous version. Preparing the foundation for the laminate is an important and responsible process. This concerns not only the leveling of the floor, but also the use of a special cushioning substrate. In this case, the alignment is carried out depending on the type of base, its general state. </ ul>
