Floor screed is an integral attribute in the implementation of construction and repair work. Often, in order to save materials and increasing the performance of the process in the screed in addition to the cement-sand mixture, a filler from solid-state components is added. One of them is clay.

Prerequisites and advantages of using clay

Floor screed with clamzite belongs to one of the best ways to align the surface. The level of difficulty performance depends on the type and features of the room where the device will occur.

In some cases, without a clamping tie, just can not do. In particular, when:

• the thickness of the plug-in area exceeds 10 cm;
• there is a need to reduce the mass of the concrete surface;
• in the room floor consists of wooden overlap;
• it is necessary to save on the purchase of cement.

The use of clay for dry band screed has its advantages. This material is different:

• environmental purity;
• strength;
• ease;
• practicality;
• simplicity of transportation.

The clamping screed is characterized by:

• increased sound insulation and thermal insulation properties;
• resistant to the negative effects of frosty and hot weather;
• the possibility of aligning sharp surface drops;
• absolute failure and inconsistency of rotting;
• minimum drying period;
• improved surface smoothness indicators.

The price of the tie of the floor with the clamzite to significantly decrease if it is done with their own hands. Moreover, this process will not cause special difficulties even in people who did not engage in the pouring screed.

Preparatory work

According to the instructions, the floor screed with a clamisite provides for the implementation of the preliminary preparation of the foundation of the floor. Preparatory work include such serial steps:

• cleaning and surface marking;
• laying all wires in a corrugated pipe;
• surface markup;
• roofing waterproofing material;
• installation of lighthouses;
• preparation of the working solution.

To get a perfectly smooth screed, it is better to use a laser or water level. Application of marks with which the horizontal plane of the screed is determined, produced on the walls.

A polyethylene film can be used as a waterproofing material. Its minimum thickness should be 100 microns. The film is stacked with the walls on the walls. Film joints are fixed by scotch.

When installing beacons, the highest point of the base is taken into account. It is on it that the first lighthouse takes place, which will be a guide for the rest of the lighthouses. For their attachment, you can use both concrete solid and alabaster. The main thing is that the beacons are as stable as much as possible.

Installation of adjacent beacons is carried out on the basis of the length of the rules that the working solution will be resurrected. The distance between the beacons should be less than 5-10 cm of the size of the leveling tool.

When applying a screed in several rooms, the installation of beacons in them occurs at one level. To facilitate the subsequent laying of clay, on the walls you can draw horizontal lines that will correspond to the location of extreme lighthouses.

Preparation of the floor screed with a clamisite involves various proportions of materials. As a rule, there is no certain universal ratio of components. The most proper decision for residential premises will be a combination:

• 25 kg of clay;
• 30 kg of concrete mix.

Before making the solution, it is necessary to pour clairzite into a separate container and pour water. Since the material has a porous structure, it will absorb water. What will lead to an increase in its strength.

Creating a clamping tie

Floor screed technology with clay can be performed in one of two ways:

• by separating the clay and concrete mortar;
• by mixing and fillings.

The first option involves the implementation of the following works:

• dry claymzite fraction 10-20 mm is distributed over the entire floor area;
• the distance to the surface of the screed is 2-2.5 cm;
• ceramzite is covered with cement "milk";
• cement film dries during the day;
• a concrete mixture is poured.

The concrete mortar is made in small quantities. After his fill, the created surface is aligned. To do this, the rule is moving between the beacons. Excess concrete is removed. After 2-3 days, the beacons are pulled out, and the holes are closed under them with cement mortar.

According to numerous reviews of the floor screed with a clamzite by mixing it with a concrete mixture is a more acceptable option. The implementation of this process will need significantly less time. Although it also provides for the presence of two layers.

Ceramzite is poured into the container and poured with water. Waters should be plentiful for good wetting material. With the help of a construction mixer, the grainsite with water is thoroughly mixed. And only after that you can add sand and cement.

On the complete readiness of the solution indicates the presence:

• homogeneous thick mass without lumps;
• gray and wet clay.

Pouring and alignment of the first layer of concrete mix is \u200b\u200bcarried out at 2-2.5 cm to the location of the new floor. Unlike the first technology of creating a screed, when using a mixed solution of a clamzite with concrete, the upper layer can be poured, without waiting for drying the first.

When pouring the finish layer, you should not reach the extreme section of the previous layer of concrete. First, the solution is stacked below, then - on top. In the same sequence, a device of the subsequent layers occurs. So that there are no cracks in the concrete base, it is recommended to add a plasticizer in the finishing solution.

Alignment of the finish layer of concrete is made as carefully as possible. Often it is necessary to return to the decoration of some areas anew. On the surface of the new floor should not remain puddle, holes, bubbles or bumps. When the device is a screed with a solid thickness, you can use the metal mesh for the surface reinforcement.

For a month, the clamping tie dries. To prevent the appearance of cracks, the floor is regularly wetted with water. Check the readiness of the screed to laying the floor covering can be using a glass jar. It turns over and leave overnight. If the bank inside is covered with an exemplary, the screed has not dried to the end.
