Screed floor with their hands: align yourself

Screed floor with their hands

Running is a floor screedrather costly procedure, especially if invited for its implementation professionals. Therefore, for most of us, the best option is a screed floor with his hands. Although, if a person is an amateur in this case, it is necessary to think carefully whether it will master such a task, because saving money, you can lose on quality.

But be that as it may, if there is confidence inown abilities and left enough free time then, of course, it makes sense to perform a self-tie. But first, we suggest to familiarize with the key stages and the details of this work, that is, learn some theory.

By and large, from a man who has decided to perform this work, required to comply with two things: the right solution for covering, as well as the ingenuity and dexterity when installing beacons.

Functional Purpose Ties

If we take the construction of multi-Houses, then for the separation of one floor from another, slabs are used, simultaneously serving for the lower apartment with a ceiling, and for the upper one, respectively, by the floor. It should be noted that these reinforced concrete products are "classics of the genre" and successfully perform their main (carrier) function.

floor screed, self-fulfillment

Screed floor with their hands

However, to further their full operationNeed quite a costly and troublesome finish. And if in the case of the ceiling the situation is more or less simple, the modern market of ceiling finishes offers a lot of options available, then in the case of sex, the matter is somewhat difficult.

Of course, the floorings for todayIt made just a huge amount, but the problem is that the usual slab or flooring, or tile or laminate or linoleum or other floor covering you will not put. This means that the owner of the premises will have to learn how to make a screed floor and to save money to fulfill her own.

The main function is leveling screedsbase. It is for this reason, it is often used in a professional environment phrase "leveling screeds." In addition, any screed must be sufficiently robust and capable of withstanding heavy loads.

So, regardless of the type and method of production, the screed is one of the main elements of the floor of the pie and is designed:

  • to align;
  • provide rigidity and strength gain characteristics of the surface;
  • to increase the thermal digestion;
  • to perform slopes on ceilings, in the process of laying the finishing flooring.

Types of ties and characteristics

Mix for styazhechnogo solution

Correctly select the material for floor screed

Features of certain types of ties to a large extent depend on the material from which it is produced. Couplers used in residential areas, are:

  • concrete;
  • cement-sandy.

The lightweight and lightweight concrete (cellular, expanded clay and so forth.) Are used as consumables. In some cases, they added reinforcing material - polypropylene fibers.

Just allocate these types of ties:

  • magnesite (magnesite);
  • dry (plaster);
  • epoxy;
  • anhydrite;
  • asphalt (mastic asphalt);
  • mosaic (terrazzo).

Also in this area in recent yearswidespread innovative technology of self-leveling floors, and more precisely, it is a question of the screed at the base which are used ready-packaged mixture by using unique recipes. However, they are in fact contain a proportion - sand, cement, fillers and plasticizers. This data is called leveling mixture.

In certain cases, in order to properlymake the floor screed allow the combination of compounds. That is, when overlaying the bottom, the underlying layer is applied with a mixture of coarse aggregate, and the upper alignment layer - fine.

Important! Choosing the mixture in order to avoid the acquisition of a fake is important to study the material for future ties. Qualitative mixture of different pure gray without reddishnesses color, but also unacceptable presence of lumps in it.

Concrete screed can be laid directlyon the plate itself, and can be on top of the thermal insulation and sound-proofing material (and may be a combination thereof). In the first case, the coupler is called "hard", while the second - "floating". Which meant to give preference, of course, solves the landlord. Although the experts in this case definitely advise if there is a bottom neighbors, it is necessary to use a sound-insulating material, and if the bottom of the basement - the heat insulator.

Screed floor with their hands in the details

Here I would like to emphasize the fact that, asknown better to see once than to hear many times. To that end, our step by step instructions - screed floor with your hands designed to illustrate the main points.

Initially, you need to prepare the ground. The surface is thoroughly cleaned of debris, should get rid of the loose concrete pieces or dust. Then run Priming work and all the cracks and crevices are sealed with thick cement mortar.

In the room where will be executed styazhechnyeworking temperature must be between -10 and + 25 0C. Also to avoid drafts therefore be kept in closed doors and windows.

If the plan is to organize a fluidthermal insulation, it is time to put the appropriate primed surface materials. At the same time you need to take care of the temporary waterproofing of walls and partitions, in order to avoid absorption of moisture from the screed. To perform this manipulation is fine strip of roofing material, which is adhered to the bottom edge of the enclosing structures in such a way that its upper edge is 15-20 centimeters above the top of the screed produced.

Slugger zero

This zero level will serve as apoint to perform all subsequent operations. This step requires the utmost concentration and precision, because its accuracy depends on the evenness of the surface of the floor, as well as the amount of material that will ultimately expended to perform screed.

Laser level

Laser level for zero spacing floor screed

We live in an age of high technology, sofacilitate this process, it is best to use a laser level. It is this instrument offers maximum reliability and accuracy compared to the outdated gidrourovnya. After performing the first mark with the above notches are made at the level of the other walls of the room, which ultimately are joined via spacing construction. This results in a line along the perimeter of the entire room, and its accuracy is characterized by the ratio to horizon, rather than to the bottom floors.

measure distances from a tapedelineated lines to the floor and it is the highest point, or zero. It is from this point parameters will repel all subsequent calculations and as a consequence will be installed beacons.

floor screed thickness should be not less than 3centimeters (otherwise it will crack). Taking into account that now the cubic content of the solution can be calculated by the formula: layer thickness multiplied by the width and length of the room (in meters).

Solid filler (wet) tie

Before you begin the process of laying the screed itselfBeacons must be installed, which guides are mounted along the horizon. At present, very inexpensive, you can buy ready-made profiles beacons made of metal, they are the best option.

Set beacons

Properly install beacons

Lighthouses sits better on the plaster, it will carry out this important but routine work as soon as possible. A correct installation is to control them using a bubble level.

Mixing the solution should ideallyuse a small mixer. Practical experience proved that the resultant mixture will be much better, than when mixing by hand. If there is none, then the kneading is performed in 30-40 liter containers hands. Especially for beginners it is necessary to remember that in order to tie was a real need to spend quality prepared solution for 1.5-2 hours. It was during this time span concrete is characterized by the best technological qualities.

To make the screed can choose one of two subspecies of the sub-floor:

  1. concrete floor, characterized by using as filler krupnofraktsionnyh components (stones, gravel, large gravel);
  2. Cement-sand species thatconditioned by first preparing a dry mixture of cement, quartz sand in the ratio 1: 4. In this case illustrates the application of portland M 400. Water is worth to pour an amount such that the resulting solution had a doughy consistency, that is not flowed.

To begin with you need to fill always farflat angle. For leveling the cast aluminum solution applied rule that gently stretches between two adjacent rows of beacons. It is necessary to ensure that the rule was pressed tightly and removed the excess solution solely on the upper edge of the lighthouse.

Far corner - start pouring

Start the floor screed must be a far corner

The first strip is placed along the wall nearzero, when it is necessary to take into account the minimum thickness of the gap and it is 2-3 centimeters. The remaining rows sequentially overlap each other, and the pitch is determined in the process. Ultimately, such actions lead to the successive what rough floor will be filled.

During the first 7-10 days floodedthe surface is moistened with water. This is necessary for the proper transmission of the crystallization process of molecular lattice formed by concrete blocks. Also in any case it can not be forced to speed up the process of hardening of the solution, as it would adversely affect its strength.

Full hardening mixtures based on cement binder takes place no sooner than 28 days. Before this period, apply top coat is not recommended.

Quality assessment performed ties

Experienced professional quality of the work doneIt determines that called the "eye." If the theoretical knowledge and practical skills in this matter is lacking, it is necessary to perform such actions:

  1. Visual inspection - screed should appear homogeneous and have a smooth gray.
  2. Apply rule (about 2 meters) in order to identify gaps. In the case of size does not exceed 4 mm, you can be absolutely sure that everything is done correctly.
  3. Check hardness. By hammer on a tangent applied to a series of strikes, if the screed is made qualitatively, the trace of such mechanical impact will be virtually invisible. Properly define the material consumption

In order to verify the correctness of their ownThe calculations regarding the consumption of materials should seek the opinion of experts. In their unanimous opinion to carry out floor screed is necessary to take the material at the rate of 10 bags of ready mix for 7-8 square meters. As tools, they are all characterized by a general construction purposes and require very low cost.

Is it possible to save money?

There is no secret. By doing rough floor screed on the ground They use less expensive materials. But to make the surface of an ideal type is used more expensive finishing screed mixture. Just cost value depends on whether the screed reinforcement was carried out. Although it is worth recalling that the use in the production of screed flooring metal grid multiplies its strength characteristics, and therefore durability.

Important parameters that affect the value ofwork is carried out and the very type of screed. For example, in wooden houses and baths unacceptable pouring concrete solution directly on wooden beams, they first need to replace the metal and the base screed necessarily the case must be proarmirovat. As a more economical version using foam concrete screed, but she never laid on the ground, and in addition its surface is at the final stage is required to be coated with a protective layer.
