venture capital repairs in an apartment or house, always faced with the need to completely remove the plaster from the walls.The reason is that the average length of service of plaster to complete its destruction as a result of changes in the properties is 25 years.And if you remember, when the walls of our homes Soviet deposited its first layer, it becomes obvious that to leave it further does not make sense.The situation with the new buildings are not much better.Bare concrete walls - quite familiar environment, meet newcomers.So unfolds a full-scale overhaul, one of the primary stages of the work in which - plaster the walls.This old time-tested method is still the most popular, as it allows to carry out any further final finishing and modify it without structural changes.Thus it is obtained a monolithic wall.In this article we will talk about what is best to plaster the walls of what technology plaster walls without lighthouses and beacons

The plaster walls
composition of the solution for plaster walls is always selected on the basis of the material of the walls andinside or outside is made of plaster.
Conventional brick walls plastered solutions based on cement, sometimes not add lime if the humidity in the room is too high, or during outdoor work.Maximum layer of plaster on the brick wall should be 30 mm.If the thickness is greater than 20 mm need to be reinforced with plaster mesh, so it does not fall off.
To produce grout need 1 part of cement and 2 - 5 parts sand.They are mixed together and then slowly added to water, and the solution is mixed until the dough consistency.
for cement-lime mortar require 1 part of cement, 6 - 8 parts sand 1 - 3 parts lime putty.Cement and sand are mixed together, then added to the milk of lime and also mixed.If the dough is too thick, add a little water and stir again.
walls of bricks best left to the professionals for plastering.Due to the smooth surface of the polished brick plaster peels from the walls sometimes pieces, sometimes with reinforcing mesh.Therefore you need to use a special primer and fittings, as well as perform a time-consuming job.
smooth concrete wall plastered with cement composition with the addition of gypsum and quartz particles.In this case, the quartz will attach the wall roughness, which is required for better adhesion of the solution to the surface.
For lime-plaster solution need 1 part gypsum, 3 - 4 parts lime.The container is filled with water, a thin layer of plaster is poured and quickly kneaded.Weight should not get very thick.Adding mortar and kneaded.
Rough concrete wall does not require a special primer with quartz, is sufficient to use "Betonokontaktom" solutions can be used as cement and gypsum.
Foam concrete wall before plastering processed primer Deep penetration plastered plaster solution, but also against the cement no contraindications.
By choosing plaster must be approached with the utmost seriousness.The correct choice will depend on the durability of the coating.If in doubt, consult with a specialist in the hardware store.Who sold a large number of ready-made plaster mixtures, which is enough to fill with water and stir.One of the most popular at the moment is a mixture of "Rotband."
Technology plaster walls
Works associated with plaster, dusty, dirty, require care and dexterity.That is why most often turn to the construction companies.The cost of plaster wall construction teams to order depends on whether you want to perform it on beacons, and the shape of the wall.Plastering curved surface will cost twice as much - about 15 USDper 1 m2.Although the prices of different companies can vary several times, and it's only for the work, excluding the cost of materials.But do not despair, plastering the walls with his own hands as possible.From the artist need patience and the fulfillment of all recommendations and technology.
Preparatory work before the plaster
First remove all the old plaster and finishing materials, if they have been purified from sagging.We reserve the bare walls.
If wall brick , then to improve the coupling of the plaster mixture to the wall recesses increase in the joints between the bricks up to 1 cm.
If the wall is smooth concrete and have to do it on a notch.Use zubchatki and a hammer.The incisions must be 15 mm long and 3 mm deep.We hope so that for each 1 m2 of wall surface had about 250 notches.
If the wall is a wooden , install shingles.You can use thin strips or plywood scraps, stuff better diagonally.It should get a crate that will keep the plaster and serve as beacons.May be used instead of wooden shingles Rabitz.It is not directly fixed to the wall, and on the veneer strips - lining so that the distance between the wall and the grid is not less than 3 mm.
Clear the walls and the room in general, from dust and dirt.
brick and wooden walls moistened with water.For these purposes it is convenient to use a garden sprayer, but it is possible to confine a broom.
Concrete walls treated with a special primer "Betonokontakt."For the walls of a porous material: foam concrete, aerated concrete or sand-lime brick, use a primer deep penetration.If the substrate is highly absorptive, treat twice.All these manipulations are necessary in order to improve the adhesion of the surface of the walls from plaster mortar.
Further work starts only after the primer is completely dry.
Compulsory follow what is written in the instructions to the plaster mix, if we do not prepare a standard mixture of the individual components.For example, consider the preparation of the most common plaster "Rotband."Bag mixture of 30 kg of water should be needed 17 - 18 liters.
pour water into the container, then add a little mixture, 6 - 7 trowel.Mix thoroughly.Then, pour the whole bag into a container and knead drill with mixing attachment.Our mission to make sure that there were no lumps.Give the mixture to infuse for 5 minutes, then continue to knead.
In the last step of kneading can even add plaster or water into a container.Later, this can not be done.
Important!The prepared solution should be used within 20 - 30 minutes.If you are new and will not be able to do the job so quickly, it is better first prepare a solution of half a bag mixture.
start plastering the wall.The technique involves the application of three layers, one by one intermittently.
Application plaster: a layer of "scratch coat»
For the first layer, called "scratch coat" solution should have a creamy consistency, more liquid compared to subsequent layers.
layer "scratch coat" for brick and stone walls - 4 - 5 mm, and for wood - 10 mm.
Using a trowel, type in the Falcon portion of the solution.Recruited from a plaster solution with a spatula and apply our strength on the wall in a random order.Spreads movement should be carried out only with a brush, not the whole hand.Do not swing too much, that the solution is not sprayed.Such an application method is preferable because the pressure pin of the solution on the wall, the particles penetrate into the voids.
second method of application - smearing.Falcon is brought to wall plaster shovel solution is taken and smeared on the wall.This method is less preferred.
After sketched solution uniformly on the entire surface of the wall, it is not necessary to flatten.It is enough to remove the outstanding areas too.
Important!All tools after each stucco area should be washed thoroughly.

Application plaster: the layer "ground»
For the second layer called "ground" slurry of need.But to begin to apply it only after the complete drying of "scratch coat".We check readiness as follows: press down with your finger, if not prominaetsya, then a layer of dry.
sketching solution on the wall, trying to patch up all the empty areas.Then spread by the rule from the bottom up.Excess remove a container with the mixture.If in the process of leveling the detected empty areas and fill them with a solution and re-flatten the rule.
then spread it spreader, with drive in horizontal and vertical direction.
Important!At all stages of the application of the plaster mixture is controlled flatness with a rule.
Maximum thickness of the second layer may be 20 mm - for wooden walls.
Waiting for the complete drying of the second layer of plaster.
Application plaster: a layer of "nakryvki»
For the third layer called the "finish coat" need to re-dissolved consistency of sour cream.It is necessary for finishing to lubricate all the flaws of "ground."
thickness of this layer can be up to 2 mm.To prepare the solution is sieved through a fine strainer to prevent the occurrence of lumps.
wets the surface of the second layer with water.Trowel a thin layer of solution.Poluterkom flatten, making a circular motion, or in a serpentine path.
Without waiting for the drying of the last layer of plaster, grout perform.
wooden float presses firmly against the wall and do counterclockwise circular motion.Sharp edges cut off the excess plaster, projections and irregularities.If the "finish coat" had time to harden, moisten it with water first, then begin to grout.
grater presses against the wall and make sudden movements straight - flapping.It is necessary to remove traces of circular movements.Then you can walk on the surface float, padded with felt, or felt to further improve its quality.
Plastering of walls on beacons
Lighthouses of plaster used in the case, if the walls have significant drawbacks, bumps and bulges.To obtain a flat surface in the horizontal and vertical plane must be checked layer of plaster over the entire area of the wall.For this need and beacons.
Technology plaster walls on beacons is quite complex to describe in words.It is better to see once than read a hundred times.Therefore we suggest to watch the video.
Majachnaja plaster walls: video - example.
for the wooden walls as beacons used wooden shingles.
For walls that are easy to fasteners used metal rails.
for stronger walls used beacons from a solution or plaster.
- markup.At a distance of 15 - 20 cm from the wall perpendicular to the top of trying to drive a nail or screw is screwed.On it hang on the rope load.This will be our plummet.At the bottom of the wall and screw is screwed at the required level.
- between the upper and lower screws apply our solution handful enough 3 pieces.
- Aluminum lighthouse install our solution, and a handful of screws.Press it into the solution so that it rested in the screws.Continuously monitor the evenness of its location.
- second beacon set near the opposite edge of the wall.Third - between them.If the wall is long, set the great lighthouse, the distance between them should be about 1 m. The technology is the same setup, but now check the evenness of the location not only in the plane, but also with each other.
- on both sides along the edges obscure beacons solution and wait until it hardens.
- plaster solution was applied on the above-described technology.The last layer should be leveling up by 2 - 3 mm extend beyond the lighthouse.
- Leveling solution is performed using the rules.We put it down to the floor near the wall, leaning on the lighthouses, stretch up, removing excess solution.With the right to cancel the excess back into the tank with the solution.
- continue to throw as far as a solution, if we see emptiness.Again flatten.When the wall is perfectly flat, we stop work and wait it dry (10 - 12 days).
construction companies for similar plaster walls price ranges from $ 6up to $ 10per 1 m2.
Finally I would like to say, plastering - a complicated matter and responsible.To the surface turned out perfectly, you will have to purchase all the necessary equipment and tools, mortar in the right amount and means for priming the walls.Saving this is not necessary.So be patient and hang in the process will be.
