The semi-dry band screed is a modern progressive technology that allows you to solve all the tasks and to level the surface in the shortest possible time on various objects. Compared to the classic method of preparing the solution, it is most effective, providing high consumer qualities and significant savings.

The semi-dry band screed, the price of which varies from the used building materials used, creates a perfectly smooth and smooth surface by using a semi-dry rigid cement-sand solution. The lastness of the latter is achieved by impurities of the polypropylene fiber, or using a metal mesh.

Properties and composition of semi-dry tie

Surface alignment solution is prepared in place. It does not spread and has a short drying period.

The cement-sand composition for a device of a semi-dry band screed consists of:

• portland cement M-400, which is used as a binder;
• wash sand (measuring 0.16-5 mm with a density of 1.8 g / cube. cm);
• superplasticizers that increase mobility, frost resistance, strength and elasticity of the mixture;
• fibers that increases tensile strength and bending.

Due to this composition, corrosion is prevented, the formation of heights, shrinkage and the occurrence of cracks, and the wear resistance and water resistance of the surface also increases.

Advantages of semi-dry floor tie

• eliminates the leakage, the occurrence of cracks and the floor shrinkage;
• heat and noise insulation increases;
• easy to work;
• has a smooth and durable surface;
• excludes dust formation;
• works on the device of semi-drying floor screed suggest a low price;
• during installation, exceptionally high-quality building materials;
• drying rows is 12 hours;
• the finished solution is submitted continuously, which eliminates the docking of the drying composition with the new one;
• next surface treatment is not needed;
• a smooth monolithic basis is formed, resistant to mechanical effects;
• involves minimal water consumption and the possibility of mounting hidden communications;
• it is environmentally friendly and polyfunctional.

Semi-dry floor screed: disadvantages

It assumes the presence of a special burning machine and a pneumatic stepper, as well as team brigades that can handle this equipment.

Use of semi-dry tie

1. Used in the presence of thin overlaps.
2. With limited repair work.
3. With the existence of the probability of floors to the lower floors.
4. Applied to gravel and sandy or rammed sandy soil.
5. Used to align concrete and wooden floors.

Materials

A reinforced metal mesh is used to create a monolithic and durable screed, which is filled with half-demarious composition, and fibrovolok is also used.

For the device, a semi-drying band of the floor (the value of which you will justify several times) with the use of fibrovolock, the following building materials are needed:

• water;
• fibrovolok itself;
• cement;
• sandy sand;
• the edge special tape of foamizol.

The following building materials will be needed to create a semi-dry cement-sanding screed based on the mesh:

• elastifiers;
• harders;
• water;
• cement;
• sand;
• wire;
• net;
• edge tape.

The following building materials are usually used to fill the semi-dry meat on a floating-based basis:

• self-election composition or tile glue;
• rolled focusing building materials;
• minvatu, extruded or foamed polystyrene foam.

Preparation of solution

To create a solution with the use of fibrovolock in the pneumatic stepper, fall asleep:

• 50 kg of cement;
• 120 liters of sand;
• 0,150 kg fibrovolok.

All elements are prevented about 3 minutes, water is added. Measure a few more minutes.

When mounting the mesh for cooking takes:

• 3 pieces of sand;
• 1 part of Portland cement M400;
• elasticizer.

In the container first falls asleep sand, then cement. Water and elastifier are added to the dry mixture, as well as ceramisit reinforcing fibers and hardening accelerators. As a result, a plastic solution should be obtained.

Instruments

For the device dry tie, we need to be needed:

• wooden grater;
• putty knife;
• vibratinglitis;
• rule;
• workman;
• thermal and beams;
• level and grinding machine;
• bethemale cheerlee or other capacity;
• pneumatic pump with hose.

Technology device semi-dry tie

Semi-dry band screed, photos and stages of work:

Method number 1

1. We prepare the foundation under the screed (we remove the garbage and dust).

2. Ground the surface.

3. Mount the damper tape.

4. We put the finished solution:

• we swell the first layer to 2 cm;
• we are tamped and mounted on top of the grid;
• slices of mesh we associate with a wire;
• we embarrass over the grid another 3-4 cm of semi-dry composition.

5. Aligning the surface:

• we reveal using the level of the foundation of the base;
• montoy the lighthouses;
• less surface with the rule.

6. We produce grout with a grater or grinding machine.

7. Cover the screed with a film and provide optimal humidity.

Method number 2 (using reinforcement)

1. Prepare the room.

2. Eliminate irregularities with a linorrome, biket or technonic.

3. Create noise insulation using isolon or foamed polyethylene.

4. We lay the waterproofing layer.

5. Mount the floating screed (thermal insulation layer):

• we reveal with the help of the level of irregularities;
• we make labels on the walls;
• we pave an additional layer of expanded polystyrene.

6. Install lighthouses.

To expand well in places where lighthouses are installed, it is necessary to do in the holes of the hole. Stop material should be tightly without gaps.

7. Summary and mesh installation:

• we mix the composition using a mixer;
• we scatter the finished solution with a shovel layer 2 cm;
• mount the grid;
• on top of the grid poured, and then a new layer of screed is smoothed;
• align the surface using the rule.

8. Grouting and grinding.

When the screed hardens, it is necessary to knock off the metal spatula of the bugs, and the places of their formation to lure. To do this, it should be mixed with a frozen surface of the spray, put the cement-sandy solution from above (1: 1) and to lure it with a wooden grater.

Next, you can remove lighthouses and polish the surface with a special typewriter.
