Before making a screed floor, it is necessary to determine which of its existing species most suitable in a given situation:

  • classic concrete;
  • self-leveling;
  • dry;
  • semi-dry.

Each of these types has a different styling and technology involves the use of different materials.

Classical concrete

It refers to the wet form. When work uses a large amount of water, which obliges to provide waterproofing floors before starting work. To carry out all the steps needed tools: laser, hydraulic or normal levels, roulette, spatula or trowel, usually a knife, beacons drill with paddle to stir the solution.

Preliminary work include the following steps: dismantling the old coating and residues covering, cleaning and degreasing slabs, putty and smoothing of defects and cracks on the basis of gender, waterproofing with a tight sealing of the holes near the pipe engineering communications.

Concrete screed is used mainly for rough floor finishes

From the materials needed: Portland cement, sand, water and, preferably, a plasticizer. The solution is prepared at the rate of one part cement to 4 parts of sand. In places where it is planned to become the largest furniture, the amount of sand is reduced to 3 parts. The mixture was diluted with water to the desired consistency, after which the plasticizer is added to it. Stirring can be carried out in any way possible, but it's best to do this drill with a nozzle in a suitable container. Since the materials are used the most affordable, we get the lowest cost per meter of floor screed. The works can be carried out independently, which further saves budget. Especially because this is not so difficult.

Initially established lighthouses on the prepared base through the meter parallel to each other. At this stage it is necessary to use a level. Then, get a niche filled with a solution to a height of lighthouses. For convenience, this is done through a single niche. Rule and trowel solution aligned to the top edge of the guide beacons. After the full screed it is necessary to periodically moisten with water to cement is cracked. Once on the surface will be free to go, you need to overwrite the existing irregularities to obtain a completely smooth surface. Full cure is through 28-30 days.

Useful advice! RStarted on the device ties in the same room must be fully completed in a single day, in To prevent deformation and fracture of the cement of the monolith along the border, which would be obtained otherwise case.

Self-leveling screed

Produced "wet" method, like the previous one. However, makes it much easier and faster. The secret that plays a special role solution mixture in which the addition of cement and sand contains chemical additives, a solution of imparting plasticity and fluidity. Because of these properties, the solution was filled under gravity spreads itself around the room, filling all crevices and niches.

It supplied mixture in dry form and diluted with water according to the instructions. Then the solution was thoroughly mixed and poured without using beacons as long as it is hidden under the surface of the uppermost point in the relief of a base. Thus it is desirable to use a leveling or laser level. The thickness is adjusted using a roller or a special brushes. The advantages of this type of screed:

  • quick drying - people can walk on it after 10 hours;
  • no need to install beacons;
  • lower complexity of the process;
  • obtaining a perfectly smooth surface, practically does not require additional processing;
  • due to the fact that the layer of smallest thickness is obtained, the weight of the screed small, which reduces the load on the overlap.
Due to the thin layer, self-leveling screed does not create additional burdens on the floor

The only drawback of this type is a very high price for floor screed meter. Work on the device it can not be worth anything if you do them yourself.

Useful advice!While self-leveling screed dries out, we can not allow it from direct sunlight. She also fears temperature fluctuations, drafts and getting wet. Under these requirements will very firm, slightly absorbent surface.

Price semi floor screed less than wet

mix semi-dry screeds It is prepared with less water. The solution turns plastic but non-flowing. This circumstance makes it possible to save on the waterproofing. All materials are the same: cement, sand and water. Only the last 30% less. The only thing to add to this set - polypropylene fibers for reinforcement. All laying technology similar to that as is "wet" plate, but in this case the solution is poured off and fall asleep. Such a method provides the time gain, as semi-dry mixture is quickly solidified. Benefits include:

  • lack of possibility of leakage of fluid through the ceiling;
  • fast drying;
  • very smooth surface, with the ability to use the trowel;
  • fibers used reduce the weight of the screed.

Due to the economies of the waterproofing, as well as the timing of the production of semi-works price floor screed is much lower than at its unit in the traditional way.

Among the shortcomings can be noted that such a thick solution may be stirred only in a concrete mixer. In addition, it is difficult to determine the required amount of water, as specific instructions on this point, everything is done "by eye".

Useful advice!After laying the screed semi-dry method, it must be very well compacted. Otherwise, it can give a crack and start to crumble.

How does the video dry screed floor with their hands

When we see in the video, dry screed floor with his hands, it seems that everything is done very simply. In fact it is not. Dry screed involves a rather complicated process alignment and mounting structures of the lag and sheet materials. The spirit level set on the basis of the joists to which screws are fastened sheets of plywood, particle board or other similar materials. But this is the last century.

Modern dry screed - is a completely different, more simple and convenient method. Its essence lies in the fact that on the subfloor using the level set aluminum beacons for plasterboard. Between them backfilled dry expanded clay chips. It is very light and does not have a big load on the ceiling. Then, using the rules of concrete block is leveled flush with the beacons. After all this, beacons are fixed ready gipsovolokna sheets. They are very durable and can withstand heavy loads.

The use of aluminum for lighthouses ties help to achieve a strictly horizontal surface floor

Deficiencies in this type of screed is not revealed yet but sufficiently high materials prices.

Useful advice! If dry screed as topcoat planned stack soft materials (linoleum, carpet or PVC tiles), the seams between the sheets must overwrite gipsovolokna filler.

If you choose any of the methods of screed is necessary to follow the rules that are developed by builders.
