When it comes to building a house, or the overhaul of the premises, we are faced with the fact that it is necessary to align the wall, and then to carry out their own finishes.It should immediately be prepared for the fact that the plaster concrete walls - is a long and laborious process that requires certain skills.In addition, stucco concrete wall has a decent price, so you can learn how it works for yourself.

Plaster walls - this is a very important step indecoration, regardless of whether the wall will later hang wallpaper or the surface is prepared for painting.

In this case, there are many nuances.Thus, some experts advise to first prepare the surface and completely clean it of flaws.Some advised to not spend a lot of effort and did not prepare a concrete wall in plaster and plasterboard just sew it.But, as it turns out, the artificial fragile wall in the future is a problem in the operation.On it can not be attached kitchen cabinets, plasma TV, shelves, air conditioning, water heaters and other heavy appliances.That is why better to choose an old proven way to finish walls and perform plaster concrete walls with his own hands.

Classification material

Currently commercially represented many different mixtures for walls.certain types intended for each surface.

Common types of plaster:

1. Gypsum (common), or a mixture of sand and cement.Such a plaster is intended for alignment of walls and to protect the surface from water and moisture and temperature influences.
2. Special.The mixture, which has a narrow focus.Its main task - to protect the room from the emissions, to keep warm and to suppress noise.
3. Decorative.The name itself says that such a mixture is used for the final stage of repair, when it is necessary to give the surface a nice view.

about technology

Before you begin any of the plastering surface must perform device plaster concrete walls.First, remove the concrete wall of dirt, dust.This is necessary in order to provide a strong bond with the surface material.After preparing the walls start to the preparation of the solution.

How to prepare the solution correctly

When it comes to carrying out plastering work should be guided by such rules:

• for concrete and stone walls, which will be continuously exposed to rain, it is necessary to use a solution consisting of portland cement or slag cement;
• stone and concrete surfaces and facades, which will be subjected to precipitation (rain, snow) can grout solution consisting of a mixture of cement and lime;
• internal plastering the premises with humidity not exceeding sixty percent (bath room, laundry room, bathroom), the first layer is applied to the cement and lime, and subsequent beds of already will consist of cement mortar.

A solution for plastering the walls of the well-screened material (through a large metal sieve) and mixed thoroughly to avoid lumps and pellets.One solution may contain one or more binding elements.Fat content of the solution is checked by a special tool - "trowel".

If the solution is very fat, it will stick to the surface and go bad.To reduce the fat content, it is diluted."Lean" solution, on the contrary, will not have a clutch and must complement one binder element.

If you have prepared a dense, oily solution, and started to work, then after drying, the wall can go cracks.Yes, and to work with such a thick solution will be uncomfortable.

Prepare a mixture for plastering can be yourself and, more importantly, adhere to basic rules.Thus, the mixing of the solution container should be deep, metal or plastic.Cement is mixed in certain proportions with sand, and then entered in the "dough", which is diluted with water and stirred.To work with the solution, it is necessary to know which layer is to be first, second or third.Each solution for each subsequent layer is preparing for his recipe.

1. To prepare the "lime putty", you need to take some lime (not slaked) and three parts water.Stir, wait until start the chemical reaction, add water and mix again.Capacity to close and leave to stand for 24 hours.
2. solution of lime."Dough" - one of the one-fifth of the sand mix, add water gradually.Dilute to the desired thickness.
3. Clay-limestone.Dough (clay) - one part, the dough lime (0.4 parts), three to six parts of sand (sand more, the stronger will be the solution), water.All components are mixed and water is added gradually.
4. cement.It consists of two parts of cement and sand or three parts.It is prepared as follows: the tank is poured cement and sand layers, stirred and diluted with water to the desired consistency.

If you decide to prepare a solution for plaster of ready mix, carefully read the instructions on the package.

How to work with the solution

plaster concrete walls, if recourse to the services of specialists has an average cost.It is calculated based on the surface area and cost of materials.

particularly work on plastering concrete walls is that often the surface is flat and smooth structure.Because of this particular layer of mortar may fall off.To avoid this, the wall makes a small incision.

Next wall treated with a primer, which will strengthen the surface and improve traction.In addition, priming mixtures prevent the penetration of moisture and mildew.

After the primer is completely dry (usually it is allocated one or two days), you can start plastering the walls.

If the surface has large swings, then use a metal mesh.Application of the mixture is carried out in several stages.

first layer - "sprayed" can be applied with a pump.If there is no special device, the plaster is applied manually with a special spatula.mortar layer thickness should not exceed five millimeters.

Before you apply the first layer, the wall is desirable to slightly moisten with water, the mixture adheres better to the surface.After the applied layer, the wall of a building aligned with a spatula and leave to dry completely.

next stage - a layer of plaster is applied over the first layer.The second layer will stay up straighter, as the mixture is prepared thicker.

Actions for applying plasters are the same as in previous times.The only difference - you need to leave the surface be dried for at least a week.

After the wall has dried completely, perform the wipe operation.Within a week, until it is dry, it should be periodically moisten with water.

After that, you can proceed to the next stage - the final.The mixture layer is prepared very carefully and thoroughly stirred to eliminate grains and to avoid getting into a mixture of non-uniformity.The wall surface must be smooth and even, and have no cracks and bumps.

Once the wall is dry, it will have a beautiful white color and becomes smooth.

Working with concrete walls

Keep in mind that when working with concrete wall is required to rub each layer.This is to ensure that the layer of plaster is firmly held.

Thus, the thickness of the second layer, it is also a major, must not exceed five millimeters, if the wall is relatively smooth.

ate your walls have different swings, when applied plaster should consider this nuance and leave more time for drying of each layer.
