Self-leveling floor with their hands

Sex - is the element of the interior of any room that catches the eye in the first place and, in many respects, determines the overall impression.Therefore, his finishing is always the highest requirements and use the highest quality coverage, the benefit of their choice today is very wide.But, you see, no matter how beautiful and modern any cover if it lay on an uneven foundation, the entire effect of "greased".Also, nothing good will come if the base coating is unstable - a floor starts to sag, creak, and as a result will not serve long.

Self-leveling floor with their hands

So, before you need to lay a coating to ensure that the base surface is perfectly aligned and have the necessary stability and strength. More recently virtually the only possible approach, this was a classic device for concrete screed its technology - with special training, setting a beacon system, carefully leveling, long full ripening.Errors, especially when placing the fill level, became fatal and subsequently de

manded large-scale work on the recast.At the moment everything can be solved much easier and faster - it is possible to pour self-leveling floor with your hands, even without special experience in carrying out similar work.The main thing - to observe the technological manufacturer's recommendations.

But above all, you must understand the types of liquid samorazravnivayuschihsya floors, with advantages and disadvantages.

Composition to fill samorazravnivayuschegosya floor is specially selected and balanced blend.In diluted to the desired consistency is the state, possessing the properties of a liquid substance, it can subject specific process conditions, independently under the force of gravity to create a perfectly flat surface. However , a special component formulation provides extremely fast setting of the solution, its freezing in the horizontal position with the creation of a flat surface, ready to carry out further construction and finishing works.

The semi-solid solution under the action of gravity itself needs to create perfect horizontal surface

semi-liquid solution under the action of gravity itself needs to create perfect horizontal surface

When this technology can be applied?

  • In order to create a thin leveling screed, directly on the concrete base, to eliminate defects (unevenness) of the old surface and the preparation for the flooring finish.Usually in this approach the filling layer thickness lies in the range 2 mm ÷ 30.
  • To fill leveling "floating" screed on separating layer, such as a roll of film or waterproofing (as an option - construction on oiled paper).This technology is justified in cases where sostyanii bases does not allow fill ties directly to it (for example, concrete is deeply impregnated with oil or butter).Another option - screed on wood base. Anyway , screed thickness varies from 30 to 60 mm (some formulations allow for Bole and thick screeds) ..
  • similar to the previous version - screed on insulation layer (eg extruded polystyrene) when floor require special insulation.The layer thickness is usually the same - from 30 to 60 mm.

  • Finally, well-suited for this kind of mixtures « warm floor", and water and electric.They enable reliable hide pipes (cables), and at the same time obtain a flat surface (usually set beacons on pipes or cables laid contours - just inconvenient).filling thickness in this case - depending on the diameter of the heating element - not less than 35 mm over its upper edge.But the overall thickness should not exceed 60 mm, otherwise it will unnecessary overspending of energy.

Now - about the varieties of bulk self-leveling floors in the main, the basic component.Once "taken out of the brackets" polymer flooring (acrylic, polyurethane, epoxy and the like .) - They have the specific scope of use or purpose of the target, and the other, more complex casting technology.The civil works are mainly used on the floors of cement or gypsum based.

An example of a mixture based on cement

Example mixes, cement-based

  • mixtures based on cement with optional polymer additives, plasticizers , provides good spreadability fresh mixture and fast its crystallization.

These floors are distinguished by good strength, they can fill in areas with high humidity levels.That cement mixtures made especially thin leveling pouring a thickness of only a few millimeters.

In some cases it would be advantageous to use a solution based on gypsum

In some cases more profitable to use a solution of gypsum-based

  • Gypsum (a more precisely - gypsum-cement) mixture ideal for leveling floors for any kind of surface finishes, but only in areas where the normal humidity createdconditions.They are often used in cases where a particularly thick fill layers (sometimes even reaching 100 mm) for leveling large differentials are required.Gypsum is a good conductor of heat, so such a mixture is very popular with installers warm floors.

More one criterion - the intended purpose of a particular type of mixture.

  • Rough rovniteli - are designed to leveling uneven grounds with large elevation changes or significant defects.Fill layer is usually not less than 10 mm (thinner coating fills strength will not be provided).As a general rule, require additional alignment before finishing flooring resilient flooring.They can be used under tile, laminate.
  • Mixes for fine alignment - are used in situations where you want to display an ideal floor surface without any appreciable increase in its level.casting thickness can be up to 5 mm.Usually used on the leveled screed, made by conventional technology of cement-sand mixture, and after equalization rougher from filling compositions.
  • Special - often called mixtures "for complex reasons."Thanks to the special component additives (such as reinforcing fibers) and plasticizers, they are given specific qualities, in particular, high compressive strength and flexural strength, increased hydrophobicity and etc .The cost of such construction mixtures, certainly much higher, but and opportunities - is much wider.So, it is used in the formulations pouring floors on the wooden base or separation layer.

Probably, all self-leveling samorazravnivayuschimsya sexes, compared to the conventional concrete screed, share common virtues:

  • Preparation of the solution to work is not particularly difficult: there is no need to accurately measure the ingredients, everything is arranged in the optimal composition and only leftdlish adhere to instructions.
  • To prepare the filling does not require a powerful technique (concrete mixer) - quite a building, or even a mixer nozzle to the usual drill.manual labor component also reduced to a minimum.

  • Because the process is completely eliminated complex and time-consuming operation - installation of beacons system for surface removal is strictly horizontal.In this case, gravity will make all.The main thing - to accurately calculate the flow mixture per square IU mp mp oschadi.To control you can use the portable tripods-frames.
  • Once beacon system is not, and the difficulties with the preparation of the solution and does not occur, then pouring the floor should be able to spend even a novice - of course, with its own appropriate level of accuracy and the unconditional adherence to technological recommendations.
  • Any concrete screed on the "traditional technology" - is not less than 25 - 30 mm thick, "stolen" from the total room height.When using thin leveling floors samorazravnivayuschihsya sometimes quite 2 ÷ 5 mm.
  • and a small thickness of the screed and its lower density - is to reduce the load on the floor plate, which is very important in high-rise developments.
Sometimes through two - three hours later permissible movement is drenched surface

Sometimes through two - three hours later permissible movement is drenched surface

  • Many mix after pouring allow you to move on on lu already after 2 ÷ 3 h.This can give a very significant gain in total time for completion of all repairs in the apartment (house).Bloodthirsty communicating room or corridor will not restrict movement around the house for a few days as a normal screed.Also, you can start much earlier and to the next processing step.

Among the shortcomings can be noted a higher price for the raw material.That is why there is often more advantageous ground, a rough alignment spend using tie, then pour samorazravnivayuschiysya thin-layer floor to get a perfectly flat surface.However, the choice is always - for the owner of property.

What kind of mixture and how much to buy?

What kind of mixture apply?A variety of them - is very large, and it is possible to select and rated producer, and target destination, and cost.

How not to get lost in the variety of self-leveling floors ?It is necessary to carefully read the instructions!

How not to get lost in the variety of self-leveling floors?It is necessary to carefully read the instructions!

no need to hurry - very carefully study the instructions, since the external similarity of compositions may be used for different purposes.As can be seen from the table, a very significant may be the range of prices (the room rate - according to the capital's online store, as of May 15, 2015 ):

and finally, in the selection and acquisition will need to onceto determine the required amount of material.The task is simple, if the ground - enough pre-aligned horizontally, and in addition, already premeditated , on which approximately the height of the layer will be poured samorazravnivayuschegosya composition.In any mortar similar purpose always specified average material consumption per square meter area with a thickness of filling 10 mm.Therefore, the mathematical calculation reduced to one formula:

M = S × h × m × 100

M - the required amount of drymortar, in kilograms.

S - The area of ​​the filling space (in square meters .)

h - The height of the filling layer, in meters (1 mm = 0. 001 m )

m - specified by the manufacturer as expenses in the area of ​​1 m² poured a layer thickness of 10 mm.

Next, the resulting value will need to be divided by the weight of the composition in a factory package to get the number of bags that must be purchased.It would be wise to take still about 5% of the stock.

simple example, on the information specified in the table.For example, in a room filled with floor area of ​​19 square meters, with the floor level rises by an average of 8 mm.composition « GLIMS-S-Level » chosen for the job.In his instructions specified rate - 16 kg per 1 m square.

M = 19 × 0.008 × 16 × 100 = 243,2 kg

us add once more 5%, we get: 243,2 + 12,6 = 255,36 kg

remains to find the number of bags. In this case the factory packing « GLIMS-S-Level » - 20 kg.

255,36 : 20 = 12,77 ≈ 13 bags

Economically, it is advisable to use self-leveling floors with small differences of level

economically advisable to use self-leveling floors with small differences of level

obvious that even at such a sufficiently thin layer of material need lot.It - still one argument to the fact how important carefully conducted training base for fill and pre-alignment of more cheaper methods.
