Over the years, many specialists use in construction the so-called semi-dry tie for filling the floor or other surfaces. This is a fairly specific technology that is based on the use of a minimum of water during the preparation of the solution.

Directly, the floor screed, created by the "semi-dry" technology, is actively used as a basic base of the construction structure, or as an industrial floor, if the surface has passed the corresponding grinding.

Create a screed on dry technology with your own hands is simple enough, and even newcomers will be cope with this task.

Features of the semi-dry tie of the floor do it yourself

As we said, the main "chip" of the floor alignment technology when conducting a semi-dry screed with their own hands is the use of minimum water volumes, so that the cement-sand mixture can dial the maximum strength during solidification. The bottom line is that with such a process begins the formation of strong crystalline bonds that are not formed if there are many water.

It is worth considering the main advantages of semi-dry alignment:

• High layer density, durability. It is important to remember that with such a technology is formed much less than the pores, therefore this fact confirms the high strength of the screed even with high humidity in the room.
• Short deadlines for creating a screed. Considering the fact that the long-term evaporation process of moisture is passed here, directly the main stage of the work turns out to be short, which is useful for construction, which requires full scope of work in the minimum time.
• "Clean" work. Given that water for construction work here is very little required, you can be confident in the purity and lack of dirt on the workspace. There will also be no dampness and other components of construction, which usually upsets newcomers.
• Parallel carrying out other works. Considering that the creation of a screed will not lead to high humidity in the room, you can study in parallel, for example, wall decoration or ceiling.

Interestingly, the dampness that is formed just during the creation of a screed, often turned out to be the main cause of damage erected structures.

The main materials for working on a semi-dry screed are limited to several positions, among which sand, cement, water, rule, self-tapping screws, metal profiles and grinding tools. In alternative options for creating a semi-dry screed, more fasteners and other components can be used to ensure optimal flights.

In addition, after creating a semi-drying coupler, only a week can be started to lay the linoleum. If the owners make a decision to lay the floor from laminate or parquet, it is worth waiting for about 40 days.

Negative sides of a semi-dry tie:

• High density of material sometimes creates problems. In the case of the lack of pores, some roundedness can be formed at the screed.
• Creating a semi-dry screed on large areas is a time-consuming process.
• The height of the screed should be at least 40 mm, otherwise the strength of the layer will be sufficiently low.

It is important to remember that the advantages and disadvantages when laying a semi-dry screed can be subjected to various dimensions depending on the room, the volume of work and other factors.

Preparation of semi-dry mixture for tie

You need to know about the following requirements for the material:

• The sand size module should be up to 2.5. The quality of the material should be high, we are talking about the absence of peat and plant residues.
• Cement should be purchased from proven manufacturers in intact packaging. It is desirable to be sure that the material was stored in conditions that meet the requirements.
• Water that is needed to prepare a mixture, it is better to take from the water pipeline. In other sources (from water bodies, well) may be impurities.

Cooking:

• It is necessary to prepare a plywood sheet, which is pouring 3 sand shovels and 1 shovel of cement. As a result, you need to create a kind of "volcano" with a deepening in the center. Gradually, we pour water into the center and begin to mix. Water needed exactly so much so that when compressed in the hand, clay sand sticking into a lump in a lump. It is important to note that when compressing the water should not be released, and the form will persist.
• The humidity of the sand can be completely different, so the water is added "to the eye". It is important to note that adding water more laid, more than easy, therefore it is worth referring to this case responsibly.

Creating a semi-dry floor screed

It is worth remembering that it is possible to equalize the cement-sand material for 45-50 minutes, so you need to prepare a small amount of material so that the mixture simply did not become unusable.

• The surface of the floor must be displayed with polyethylene, which must go a little on the walls. Instead of polyethylene, you can use more expensive materials, such as rubberoid or hydroizol. Also along the walls you need to position the Plipropylene cassetting tape. Materials and tools that are used to conduct a semi-dry screed with their own hands should be in the initial state, as it is about creating the most smooth surface and the absence of impurities.
• On the perimeter of the room, you need to screw the screws that will be a certain surface level indicator. It is necessary to apply the construction level, on the basis of which the self-adjustment will be adjusted to the desired height.
• Along the line that connects the screws, you need to arrange a bunch of solutions that are attached by the usual shovel. It is worth a clearly examine the recipe, which we talked about earlier and quickly fulfill the entire amount of work.
• Between the self-pressing, over a pile of solution, you need to position the metal profile used to fasten the plasterboard structures.
• We have a self-tapping screw in the same way, but a little further and parallel to the first piles. We also put the material, and then we do the same procedure with the rest of the small surface area already without self-tapping screws. The level is worth checking on the side two labels created using self-samples and profiles.
• With the help of the rule, the mixture is recompuling. It is necessary to carry out the procedure as quickly as possible and better, as the timing is limited. Next, the surface is grouped. After about a day, you can work on the correction of surface deformations.
• As a result, when everything is ready, you need to put on top of the surface of polyethylene and leave the room in this state for a week. With summer heat, it makes sense to wet the floor within 5 days after the arrangement.

Specialized equipment for holding a semi-dry screed is used extremely rarely, only if the scale is industrial. Moreover, in such cases it is advisable to use a simple screed with the usual amount of water. We are talking about mechanized creating and applying a semi-dry screed, and only specialists produce these events with their own hands.
