Repair has a few goals - update the dwelling, change its appearance and create something new. The best way to achieve the desired is to redecessing the house. At the same time, it is possible not only to aesthetically transform the dwelling, but also to create an additional room. Sometimes this factor is decisive when deciding on redevelopment. Increasingly, consumers create inner partitions from foam blocks - the material allows you to quickly and efficiently build a interior wall with your own hands.

What is foam block?
Foam block consists of a mixture of concrete and a synthetic or organic foaming agent. With mechanical mixing of components, air bubbles are evenly distributed in the solution, and after it is frozen, it turns out durable, but relatively lightweight building material. Partition from foam blocks, the price of which depends on the class of strength, in any case it will cost cheaper structures from the brick.
Foam concrete composition:
- cement;
- sand;
- water;
- foaming agent.
Advantages of foam concrete blocks:
- high sound and thermal insulation properties;
- environmental friendliness;
- fire resistance;
- large size - the parameters of the foam block allow you to quickly lay out the interroom wall and reduce the costs of the binding solution;
- small volumetric weight;
- the porous structure of the material - due to this property of the septum from foam blocks "Breathe" and there is no effect of foaming;
- ease of processing - the material is cut into both power tools and a simple hacksaw, which allows you to create partitions of various shapes and without much effort to lay engineering communications;
- uncomplicated installation;
- wear resistance;
- available cost.
Disadvantages of foam block:
- the fragility of the material - with improper transportation, its damage is possible;
- the need for waterproofing walls - porous concrete has a high degree of vapor permeability and water absorption;
- limitations on the load of partitions - problems may occur when massive, heavy items on it.
Preparation for work
Focoblocks for internal partitions - Material selection
When choosing a material for interior walls, pay attention to the following factors:
- the thickness of the foam blocks is 10-15 cm;
- the density of the material - for the internal partitions, the D600 brand is usually used;
- uniformity of the structure;
- the form of bubbles - they must be round and small (diameter up to 1 mm);
- no differences in foam block sizes - it happens that the difference reaches several centimeters;
- packing material - it should be covered with a film to protect against moisture;
- lack of cracks and damage.
Calculation of the number of foam blocks
To calculate the number of foam blocks, the parameters of the future wall are measured. For example:
- its length is 4 m;
- height - 2.5 m;
- thickness - 0.1 m.
It takes into account the area of \u200b\u200bwindow or door openings - in this case it will be 2.0x0.7 \u003d 1.4 m². The length of the standard septum foam block is 0.6 m, the height is 0.3 m. Its area is 0.18 m².
Directly the calculation itself:
- it calculated the total area of \u200b\u200bthe wall - 2,5h4 \u003d 10 m²;
- from the result obtained, the area of \u200b\u200bthe doorway is taken - 10-1.4 \u003d 8.6 m²;
- calculated the amount of foam blocks: 8.6: 0.18 \u003d 47.8 units.
So, for the erection of the partition area of \u200b\u200b8.6 m² will need 48-49 of foam blocks.
Tools and materials
For masonry walls of the foam blocks used a mixture of two types:
1. Classic solution - a mixture of sand and cement in proportion of 1/4. By minuses of such a masonry method refers to the thickness of the seam and, as a result, an increase in the "cold bridges". The pluses are low cost of such a solution.
2. Special glue - optimal material for laying wall. His advantages:
- thin seams;
- ease of preparation;
- excellent clutching properties;
- smooth, smooth wall surface.
For mounting to the wall, mortgage pins are used - steel plates with welded reinforcement. On the floor, the partition is fixed with the help of pins-screws.
The following tools will need to work with foam block:
- hacksaw, planer and grater;
- drill with nozzles for kneading the solution and creating holes for the outlet;
- rubber hammer;
- level;
- capacity for mortar or glue;
- trowel or spatula;
- marking Tools: Laser Level, Cord, Marker or Pencil.
Foam block septum with their own hands - Installation
- The surfaces adjacent to the mounted design are cleaned of dust and ground.
- With the help of a laser level, chopping cord and marker on the floor, the ceiling and walls are marked by the boundaries of the future partition.
- To prevent the displacement of the first row of foam blocks, a metal profile is attached to the floor. It is used as a limiter and facilitates the accuracy of laying.
- Self-screws screwed into the floor. It is possible to lay the first layer on the solution - in this case, the fasteners will not be needed.
- Mounting pins are attached to the bearing walls or segments of the reinforcement rod are clogged. Fasteners should enter horizontal laying seams every 2-3 rows.
- The first row of foam blocks is stitched along the level. If necessary, the size of the material is reduced by hacksaw. Since foam block is fairly fragile, align the wall should be carefully using a rubber or wooden hammer.
- The masonry of the second and subsequent foam block rows is carried out by "rotary" - vertical joints should not be located over the other. The masonry will be denser if the foam blocks are wetted with water.
- In the process of construction of the wall is formed by the doorway. To strengthen the structure at its top part fit and fixed armature spacer wedges. It is set in the pre-cut slots in the foam blocks.
- After raising the walls, the resulting gap between the masonry and the ceiling are filled with foam.
- Partitions Interior foam blocks in several layers are processed by primer and then plaster under the wallpaper or other finishing materials. Facing the wall tile is carried out directly on the wall. In this case, plastering the partition is not required.
