There are many options for the ceiling finishes, but the whitewashes are the most popular of them. It costs inexpensively and looks very good if the paint was put correctly. Typically, the ceiling is recommended to thoroughly clean the lime or chalk from the old layer before applying a new one. but you can put the following layer of paint and right on top of the old. The main thing is to know how to do it in order to make a good result guaranteed. There is nothing difficult here - possessing the necessary knowledge, anyone can cope with it independently, without spending a lot of time to fulfill all the necessary work.

What to bother the ceiling?

• chalk;
• lime;
• water-emulsion paint.

Each of these options has its pros and cons.

Table. Materials for whitening ceiling.

Material	Benefits	disadvantages
	The chalk gives the ceiling exceptional, shining whiteness, so it will look very good.	This material is gradually sat down, thus, an additional dust appears in the room. In addition, it is not water vehicles, so it is not suitable for painting the ceiling in the bathroom.
	The lime glasses kill the fungus, so in the premises where it is present is worth using it. In addition, lime is resistant to moisture and well suited for painting the ceiling in any room, including in the bathroom (namely, the fungus can be found most often). In addition, the lime glasses hides small surface defects, close up of gaps and cracks.	Lime quite often causes allergic reactions. It can not be perfectly white, in contrast to the chalk solution.
	This kind of paint has an excellent appearance, and it is precisely a water-producer very well on the old coating, it perfectly sticks to the already existing whitewash and does not begin to peel over time.	In the water-mounted paint, only one drawback is to carry out work with its use, at a temperature not lower than + 5 ° C, but when painting the ceiling in the room it does not matter.

If you do not want to wash off the old blotch, you need to keep in mind that it is impossible to apply lime on the chalk and, on the contrary - otherwise the paint will fall badly, dirty divorces are formed on the ceiling.

On top of the chalk, you can put a new layer of chalk or water-emulsion paint, and the lime can be covered with the same emulsion or lime. At the same time, it is necessary to take into account that for painting on top of the old layer of lime or chalk, the enamel and oil paint are categorically not suitable.

Instruments

There are three main ways to apply blames for which you can use:

• roller;
• brush;
• spray.

If done paint rollerThe paint will fall to a smooth layer, nor divorces, no spots at the same time. In order to get a good whitewash, using this tool, the coloring makeup will be needed in two layers. In addition to the roller itself, it will take a container for the solution, something for mixing and a greasy tray. Also need a small brush to put paint on the ceiling sections on the joints with the walls - the roller make it gently, not blurring the walls, it will not work.

Brush for bliss You can purchase in every building materials store. It should be inexpensive. While working with a brush, paint is very sprinkled, so you need to carefully protect furniture in the apartment, as well as your eyes.

Using a sprayer Poons can be easily applied a very neat smooth layer. In the event that the paint is applied to the sprayer, you need to carefully trace it to be without lumps. Its consistency should be more liquid than the whitewings have to be applied using a brush or roller.

How to choose a waterfront paint

If everything is more or less clear with chalk and lime, then the choice of suitable water-emulsion is more complex task. There are many varieties of these colors that differ in composition and properties.

1. Polyvinila acetate Water Immulsions are the most affordable.
2. Paints with acrylic additives - Most Popular. They are suitable for any surfaces and resistant to abrasion (although in the case of paint for the ceiling, this property is not so important).
3. Silicone The water-mounted paint lies well on top of the old whitewash even without the use of primer. It is distinguished by high vapor permeability and perfectly suitable for painting the ceiling in the bathroom or in the kitchen. This type of coloring composition reliably protect the surface from the appearance of fungus.
4. Water-emulsion paints with latex They differ in very good water resistance, they can be washed with detergents. At a price, they exceed all other water issues.

In order to make the best choice, carefully read before buying a label. It should indicate the purpose of paint, the degree of shelterness, the flow rate of one square meter and other parameters to be paid attention to. Properly selected water emulsion will make it possible to make a snow-white and durable coating, it will not turn yellow over time and guaranteed the ceiling from the appearance of fungus.

Painting of water-free paint

In order to get a good painting over lime, it is better to first cover the old layer of acrylic primer. After that, it is necessary to check the surface for strength, trying to scratch it. If it does not appear, you can apply paint.

But when painting, on top of the chalk, it is not necessary - the water-level paint will advantaged well and will stay without soil.

Before starting to work, you need to prepare the room. It is necessary to make or carefully close the film all items so that they do not bother paint.

If you put paint with the brush, put the smears first perpendicular to the windows, then in parallel. If the last layer is laid parallel to the light source, the bands after drying will not be visible.

Painting with a roller - a simpler and convenient process at which you need to perform the following steps:

• pour the paint into the malarious tray;
• plunge the roller in the bathroom, and then ride it down the slope, evenly distributing the paint on the surface and giving a track is superfluous;
• put the first layer of paint perpendicular to the windows;
• wait for a complete drying of the composition;
• then add the second layer, which must be located in parallel to the window to the window;
• carefully digging the sections of the ceiling on the joints with the walls of the brush.

Apply the paint from the sprayer is even easier - it is enough to put three smooth layers, you do not need to follow the direction. The main thing - when applying each of them, not to skip a single square centimeter of the surface.

Painting chalk

Prepare a chalk solution for painting the ceiling is easy; for this:

• on 10 liters of water, it is necessary to take 5 kg of chalk and 50 g of joinery glue;
• the consistency of the solution should be such that it does not glare with a knife, if the mixture is poured from the blade, you need to add more chalk;
• you can add to the composition of blue, in this case the ceiling will be snow-white, without a yellow shade.

Technology Painting with chalk fundamentally no different from the technology of application of water disposal. First, select one of the options - application of brush, roller or spray. Then, in the process of painting, do not hurry and carefully watch the composition lay down to a smooth layer. In this case, the new kind of your ceiling will surely please you.

Painting with limestone

In order to make a solution of lime for painting the ceiling, you need:

• take 2.5 kg of lime, add 100 g operated salt in water and a small amount of blue;
• mixing all the components of the mixture, add water to them so that the outcome volume amounted to about 10 liters.

The basic rules of application are the same as for chalk and water-emulsion paint.

Important moments

When paving the ceiling necessarily need to take into account the specifics of the room. For example, in the bathroom you need to use a special composition, which will be resistant to moisture and protect the ceiling from fungus. Otherwise, the paint will quickly lose appearance and can even start turning pretty quickly.

It is also important to remember the safety during painting. In order to avoid hitting the eyes into the eyes, on the skin and in the respiratory tract, you need to use safety glasses, rubber gloves and respirator. If this is not done, the coloring composition can cause allergies or even chemical burns.

How to wash off the ceiling old bliss

Despite the fact that the ceiling can be painted on an old whitewash, the best option for high-quality painting will be pre-cleaning and surface alignment. Old blotch, which keeps bad and peeling, it is necessary to wash off. If this is not done, you do not have to count on a good result. If the layer of lime or chalk, which is already on the ceiling, thin, smooth and keeps well, painting right on top of it will be quite a good option.

In order to wash off a chalk whitewash, it is necessary:

• take the foam foam sponge and moisten it in water so that it is wet, but the drops with do not flush;
• after that, it is necessary to carry out a wet sponge over the ceiling once again, washing out one layer after another, while it should be saved as often as possible;
• then you need to carefully wipe the ceiling with a wet cloth - it is also necessary to dip it into the water as often as possible.

Wash the layer of lime a little more complicated, because:

• first of all, it is necessary to moisten the entire ceiling; To do this, you can use the pulverizer;
• using a spatula or scraper, you need to remove the broken layer of lime;
• and finally, you need to thoroughly wash the ceiling with a crude cloth or a sponge to remove the remains of lime and dust from it.

Removing the old whitewash: A - Moisturizing the ceiling, B - Remove the splashing coating.

It is better to work on the plots - while you will shoot a spacious lime from one of them, the other will be drinking moisture. Thus, you can quickly go through the whole ceiling.

In order to wash off the old bliss, you can also take advantage of special compositions.

1. In a construction store you can purchase a special wash. It must be applied to the ceiling with a sprayer. When it dries, a crust will appear on the ceiling that you want to remove with a scraper. After that, the surface will need to simply wash the cloth.
2. Another option is to add vinegar to the water (one large spoon is enough to 5 liters) and 50 ml of the foam for the bath, mix thoroughly and apply to the surface of the ceiling. Wheeling 20 minutes, it can be cleaned with a scraper, and then rinse thoroughly with a wet rag.
3. Another way is to make a holter, mixing the water with flour. It should be applied to the surface of the ceiling and give it to dry, then you can easily remove the whitewash.

This solution is good because:

• it will help save time;
• turning to a good master, you can be sure that you will get an excellent result;
• the master will need a minimum of paint in order to bother the ceiling.

At the same time, as mentioned above, the whims really does not take much time. Therefore, contact the master in order to save time, it makes sense first of all if you are a busy person and have accustomed to always hire professionals to fulfill certain works.

Due to the fact that the master is consumed by at least the paint, the appeal to him can do badly more expensive than painting the ceiling with their own hands. The main thing in this business is to find a really good specialist who will take a little at the same time. The main thing is not to hire a halitchikov who, working after the sleeves, can make even worse than it would have happened - such masters also come across. They take a little for their work, but such savings in the end will cost much - you will have to either redo it, or stay with a poorly painted ceiling.

The ceiling over the old paint is a simple and inexpensive way to improve the interior of the room. It is not always possible to use it, but in the event that the former layer is thin, smooth and keeps well, chalk, lime or water-emulsion, applied directly to the old paint, will hold well.

Video - Ceiling with your own hands

Today, the market shows a huge selection of finishing materials. At the same time, the usual whitewas, used for many years, still does not lose its popularity. There are many good reasons for it. Our article will tell about them, as well as how to bother the ceiling at home yourself.

Benefits

Pooks has a number of indisputable advantages.

• Low cost- One of the most important advantages of this type of work. With a limited budget, the whits are simply indispensable. That is why for decoration of walls and ceilings in budgetary organizations (schools, hospitals, etc.) still use lime and chalk bliss.

• Simplicity. Absolutely everybody can cope with the work on the deposition of blots. This process does not require special knowledge, skills or special physical strength. It is important only to comply with the proportions, stages and work technology.
• Accuracy. If you correctly apply a whitewash, you will get an excellent smooth surface of fresh and monophonic color. Yes, by attractiveness, the whirlwinds are inferior to expensive wallpaper or decorative plaster, but when laconicity and tidy is required, it does not have equal.

• Ecology. Safety bliss is achieved by the ability to skip moisture and air. It does not have harmful substances that are in other modern materials.
• Bactericidal propertiesWhich possessed, perfectly protected from mold and fungus, which also highlights it among other materials. This is another reason for which this version is preferred in pre-school, educational and other institutions.

As already mentioned, for proper blots of the walls, special knowledge and skills are needed. Even performing work with this material for the first time, perhaps learn right in the process. It should be examined in advance to parsing technology, learn about the types of materials and tools, take into account other famous nuances. Then even repair with your own hands will be performed quickly and efficiently.

Surface preparation

If you do not have information than the walls bleached before, check it is quite easy. Just moisten the wall of the wall with water. If it was a limesky whitewash, the wet surface will become darker. You can also lose the section with your finger. From the limestone, the finger will not be painted.

Proper preparation for the deposition of blots is an important stage affecting the final result and success of the work.

In the preparation of the walls, follow the rules already proven.

• First of all, free the room from all furniture and technology, if there is such an opportunity. If this is impossible to do it, carefully cover everything with a plastic film and secure the scotch.
• To easily remove the old bliss, wet her in advance. Wash the walls in parts, then the moisture will not have time to dry. For the very washout, the plain is recommended to use a conventional soap solution. Also advise to add a little vinegar to water or a portion of citric acid.
• When you watches the walls with a wet sponge or brush, it's time to move to the removal of an old whitewash the ordinary spatula. It is desirable that the pieces of the old whip do not fall, for the preservation and purity of the floor and other surfaces. For this, pieces are folded into a separately allotted container. After removing the spatula, all the remnants finally wash the wet sponge.

• In case there are visible stains, we give the walls in the proper form:

1. Rust stains wash off and treated with the following solution: in a liter of hot water diluted with copper cuneition in the amount of 50-100 g.
2. Fat stains are removed using soda calcined. Wash the vehicle in 2% and applied to the flax of the fat until it finally disappears. Then this place must be rinsed with water.
3. For spots of soot, 2-3% composition of hydrochloric acid is used.

• Then the antifungal composition is applied.
• If there are cracks and dents, it is necessary to pre-get rid of them. With cracks up to 1 cm, it is enough to take a putty. If the depth of irregularity comes to 3-5 cm, the plaster should be used.

The putty is bred according to the instructions, then applied and align with the spatula.In case of serious irregularities, use the construction rule.

• When the putty will finally dry, it is watched by sandpaper. Now we have a smooth and smooth surface of the wall, ready to apply primer.
• The composition of the primer is made independently or take the finished mixture. After applying, one should wait for complete drying.
• Now you can proceed directly to whitewash.

Material options

Speaking about the types of blotches of the walls, mean limestone or chalk composition, as well as water-emulsion paint.

Lime

The most popular view of the blots. Lime, which is calcium oxide, you need to sneak with water, thereby obtaining a finishing material for finishing works.

The main advantages of the lime view of the blots:

• bactericidal and antiseptic properties, thanks to them, lime willingly apply in public institutions or when the cellars whitewash, for example, it also conducts trees processing;

• liminer whims is kept from 3 years;
• high resistance to humidity and significant temperature drops allows the use of blades to repair in bathrooms;
• adhesion with most materials: concrete, wood or brick;
• the ability to fill fine irregularities and cracks;
• very low cost.

Among the disadvantages can be noted:

• chance to get a burn, so all work needs to be performed in special protective clothing, respirator and gloves;
• lime can leave divorces and stains, however, they are easy to remove;
• it is not recommended to use in the presence of allergies.

a piece of chalk

In addition to the fact that the chalk is also eco-friendly and inexpensive, it has other advantages:

• safe application;
• more rich white color, unlike lime;
• hypoallergenicity (safe for people with allergies).

However, the chalk has certain disadvantages.

• Interacting with water, the chalk accumulates it. This contributes to the formation of cracks and fast exfoliation. In this regard, in rooms with high humidity (kitchen, bathroom, etc.) do not use whitewash chalk.
• With incorrect application, both divorces and bubbles are possible.
• To all other things, the whitewasure with the help of chalk is very much dirty everything, with which contacts.

Water-emulsion paint.

Often you can hear the phrase "whirlwind of water-level paint". In fact, this technology cannot relate to whitewash, but is painting. Perhaps it was mistakenly equated to the types of blots because of the lime and cement in the composition.

Coloring with waterproofs is called a good alternative option to whiten.

Advantages of water-mounted paint:

• moisture resistance;
• wear resistance;

• high bactericidal properties;
• ecology, paint ability to "breathe";
• easy application;
• high speed when drying;
• safety.

The main disadvantage - the suspension has a high cost, if compared with an ordinary whitewash. Also, the durability of this coating leaves much to be desired.

Using whitewings is considered one of the most inexpensive types of repair. You can cheap the walls not only with your own hands. Building brigades also request low amounts. The cost of blissing in one layer for an area of \u200b\u200b1 m2 may begin even from 50 rubles.

Of course, the price varies greatly, depending on a number of factors:pollution and the need to clean the walls, the required number of layers of lime, etc. In order to correctly calculate the approximate cost of work, you need to know the square and the necessary types of repair work on the preparation of the surface.

How to repay and dilute lime?

The process of preparing lime blots requires attentive relationships and accuracy. It can easily be performed by itself, observing certain recommendations.

First prepare the ingredients needed for the solution in the correct quantity:

• harated lime - 2-3 kg;
• water - 10 l;
• pre-clumsy large salt - 50-100 g;
• 1 tsp. Sinky (to obtain white color) or from 400 to 500 g of dye;
• aluminum Komasians - 150-200 g

Mix the components and dissolve them in a liter of warm water. After that, the volume of the mixture should be made up to 10 liters and how the resulting composition should be mixed.

The characteristic feature of the lime hated is its excellent compatibility with any dyes. That is, in the process of mixing the raw materials and dye in the correct proportions, you can create any necessary shade.

If you create a color whitewash, it is better to prepare the total amount of solution required for the entire surface of the walls. This is due to the fact that it is almost impossible to repeat the shade, even if you apply all the ingredients used.

Neighted lime is easy to pay on your own right at home. Stir it with water one to one and mix 15-25 minutes. Then you need to remove the lime for 15 days into a hermetically closed container. Then the lime will fall on the applied surface smoothly and smoothly, without any divorces and stains.

Consumption whims from lime largely depends on the tool that is used to apply it, as well as the characteristics of the material. On average, the flow rate is 0.5 liters per square meter of the surface.

Improving the quality of the composition

To improve the composition and prepare a high-quality and wear-resistant mix, professionals use simple, but effective ingredients. For example, add to the composition of the economic soap or various glue. In order for the whits to be better protected from flushing and temperature drops, use olive, well repulsive moisture and helps to increase the durability of the blots. Also, additives allow you to maximize the shower of the plays from the walls.

So that the spam walls do not pack everything that contacts them, add a mustache salt. You can use all the above additives.

To obtain the desired effect it is important to properly observe the necessary proportions:

• on 10 liters of blends, Kilograms of salt and lime are added (salt helps to make snow-white walls);
• 1 bucket uses olif in an amount of 100 ml;
• the grated economic soap is diluted with warm water, and in the process of preparation, water is replaced with soapy solution;
• use a wobble or pva glue.

How to beat?

Splits are applied by the following tools:

• rollers;
• brushes;
• blowing air vacuum cleaner;
• kraspopult.

The first 2 options, namely, rollers and brushes are more popular and universal.

• Work roller is easiest. It turns out quite easy to achieve a white smooth wall covering. Before starting to start work, mix the mixture thoroughly, and after starting the whipping roller. You need to apply at least two layers. First, give the end to dry the first, and after you can apply the second.
• When making a whitewash brush, you should take a special model having a natural bristle (width from 15 to 20 cm). Upon completion of the repair work, the brushes are washed so that they can be reused. For walls of bricks, you should take a painrol brush. For a while before applying, the brush is soaked in water. Due to this, the wooden handle will swell and will better hold the bristles, which prevents them in the composition.

Lime for whitewashing at home is applied for a long time and refers to one of the cheapest materials for the decoration of the walls of the buildings. And not only at home. Lime can whiten the surface of the walls of the cellar, the barn, stoves, chicken coop. In addition, everyone knows that the Garden Trees are packed with the roasted lime to protect them from the temperature conditions and the invasions of insects. But despite the simplicity and low cost of material (lime), you need to know some nuances when applied.

Content

• Write breeding.
• Teaches surfaces.
• Pros and cons.

Hazeling

In stores and in warehouses, you can buy three types of lime: hawed, non-hawed and natron (mixture of extinguished and not extinguished lime). But for the blots of the walls it is best to use a haired lime.

Why? Because for finishing works, the so-called "Lime Milk" is used, which is obtained as a result of damage not to groomed lime. How it is properly and safely to carry out the process of quenching. Consider below:

• After the acquisition of lime (not extinguished), it is necessary to break too large lumps, but not up to the powder stage.
• Place all this in a metal container (galvanized bucket).
• Pour into the capacitance of clean cold water. After contacting with water, the lime will begin to grieve and spray, so you need to close the bucket and move away.

• By expiration of 20 minutes, it will be necessary to mix the composition. In this case, protect all the bare parts of the body, put the glasses and rubber gloves. If the solution drops on the body, you need to quickly rinse this place with water.
• Complete dissolution of lime occurs after six hours.
• After that, the prepared solution is focused through the gauze (it is possible through the categorous stocking).

• As a result, it turns out a lime milk ready for use.

Some wizards are blissing to increase strength and so that the walls are subsequently not dirty, is added to the salt and oil solution. The proportion is as follows: 10 liters of solutions are mixed with 10 liters and the same salt. It happens that the solution turned out to be too thick and to fix it, you need to add water to the desired viscosity. In addition, you can add a little bit of blue, which will give lime to whitewash the white tint house.

As you can see, it is not very difficult to guess. However, it is necessary at the same time not to neglect individual means of protection, so as not to burn the skin and eyes.

Tempets surfaces

Before proceeding directly to whitewash, you need to decide on a tool for work. Application of the milk on the surface is carried out in two ways: brush and spacing. In the old days, the blades were carried out exclusively with a paint brush, but with the arrival of modern technologies, the process is increasingly using a spray gun.

Although, if the placle is small, the rational will apply the brush, but the large areas are better to handle the material by spraying the material. So it turns out more beautiful, even more economical.

The pulverizer can be replaced by an ordinary paintopult: electric or mechanical. Since the sizes in size is less than the spacing, the blasting is easier to be sent to hard-to-reach places.

An equally important action will be the preparation of the surface of the walls under whitewash. It depends on the evenness of the plating layer, its strength and aesthetic component. From the surface of the walls, dirt, greasy spots, rust and old paint, with which the lime is poorly in contact are removed.

Also close all the cracks, tubercles are smoothed. Before paving, all windows, doors, interior elements are protected by waterproof materials in any available way.

Three useful advice:

• If you break the tassel, it is for a couple of hours to soak in water. This will avoid the fall out of the hairs of the brush that can get on the wall, reducing the quality of work.
• Lime milk will be better in contact with the wall surface if the last moisten with water.
• When paving the ceiling, the first layer is applied from the window perpendicular to the light. The second layer is laid parallel to the light (sunshine). This coverage provides and eliminate the appearance of divorces.
  The lime layer after drying is not dirty. What you can not say after the plain chalk.

Pros and cons

pros

• Low value of the material. Good price and quality ratio.
• Kills harmful bacteria.
• Excellent moisture resistance.
• Protects the walls from the formation of fungus and mold.
• It does not crack when temperatures drops.
• Ecology.
• You can apply to the old whitewash.

Minuses

• When weaning, caution is required.
• The thin layer of lime when frozen is very durable. Therefore, when you hit the furniture, windows, doors it is laundered with difficulty.

Bullen or paint ceilings are recommended only after the old finish will be removed. However, this is quite complicated. Consider the old chalk or lime from the ceiling for a long time and tedious. In addition, the dirt after that the house remains a lot. Previously, glue was added in the chalk solution before palace. If the surface is finished with such a means, its purification and turns into torment at all. Therefore, for sure, many owners of houses and apartments would like to know whether the ceiling was possible on the old whitewash, and how to properly carry out such an operation.

What you need to know

In principle, painting or bleach ceilings without removing the old coating. But far from all cases. So, for example, according to the old packer, chalk is extremely undesirable if it is covered with lime (and, accordingly, on the contrary). Otherwise, non-accurate divorces will be available on the ceiling. If you do not want to consider the old coating, it is necessary to bleach the ceiling by the means that was used earlier. It is also not necessary to apply lime or chalk if the surface was previously treated with water-based paint. The surface simply does not block. The ceiling will remain yellow how many layers would not be applied.

Using paint - Is it possible?

Many owners of houses and apartments are asked by the question, including whether it is possible to bleach the ceiling on the old whitewash with a water-emulsion. It is believed to use this tool is permissible. But only if the layer of old finish is not too thick and keeps on the ceiling quite tight. Oil paint or enamel to apply in no case. When using them, the old coating will still be deleted.

Preparation for finishing

In the event that you decided to perform such an operation as the ceiling over the old whitewash, you will have to carefully prepare an old surface before processing. The chalk on the layer of plaster usually lies exactly. Lime can be squeezed. Therefore, in the latter case, before Pooring, you need to check the entire ceiling for such details. Of course, all the departed pieces should be removed by a spatula. After performing this operation on the ceiling, of course, unevenness will remain. They need to be selected by a special chalk powder or thick lime solution with the addition of a small amount of PVA glue (depending on the type of old finish). Of course, you need to miss all the cracks on the surface and chip.

Before you start it, it is advisable to go through a damp cloth in order to remove dust, web, etc. often happens and so that the old chalome or lime coating has a yellow color. After applying a new finish, this yellowness is likely to still shine. Therefore, before performing the work, such a changed color should be whiten. Such a need, for example, it will necessarily arise when finishing the kitchen. Yellow ceilings come in the event that someone from the owners smokes right in the apartment. To whiten such a surface is easy. It is enough just to add to that water into which a rag is loose at cleaning, a little inexpensive means "whiteness". If the ceilings are very yellow, they should be wetted in a cooked roller solution. Next, you should wait when the surface will dry.

Packers of the ceiling on old whitewash: technology

Chalk and lime usually have not too good adhesion with concrete. Therefore, the ceiling previously decorated with such a means should be processed using non-roller, but a pulverizer. In this case, the surface will be smooth and neat. Roller use is also allowed. But when using this tool, during the execution of work, you will have to closely ensure that there are no divorces on the surface. Of course, to break the ceilings on old lime or chalk layers need not to one, but at least in two or three layers.

Use of water-free

Having wondered about the old whitewash, it should, of course, decide on the type of finishing used. Chalk and lime at the design of the halfwalks today are extremely rare. In most cases, owners of apartments and houses use water-emulsion paint. This remedy for the surface of the ceiling is much smaller. In addition, the water-emulsion is not extended over time. But of course, this finish will last for a long time if it is correctly applied.

Before staining, the bleached ceiling is to be projected. This should use a special means of deep penetration. After the primer dries, you need to test the old coating for strength. To do this, just try to scratch the ceiling with a spatula. If the old coating is easily removed - it is better not to risk and still remove it. If impregnated with the primer chalk or lime hold on hard - you can start staining.

Sometimes the owners of apartments and houses separate the coil ceilings with water-emulsion and without prior priming. It is also permissible. But only if there is a very high-quality paint from a good manufacturer.

Basic rules of bliss

Of course, before the start of the execution of such an operation, as the ceiling whitening over the old whitelle, the room needs to be prepared. Floors and furniture should be closed with a technical polyethylene film. In the hands you need to wear rubber gloves. In particular, it is important if it is used for processing as it is known, it is able to severely erod the skin.

All doors and windows before starting whitening ceilings with water-emulsion, lime or chalk must be closed. Otherwise, the ceiling after drying will show ugly divorces and stripes.

Application of special tools

The sprinkler gives a very thin layer of finishing. Therefore, the plains of the ceiling on the old whitewash the waterproof when applying this tool should be made at least three layers. This allows you to get a flat, absolutely white and clean surface. Before applying each subsequent layer, it is necessary to wait until the previous will die completely. This rule, by the way, is observed both when using collapse and roller.

Is it worth separating the surface without preliminary cleaning?

So, we found out - is it possible to bother the ceiling on the old blotch. In principle, this is allowed. Under all the recommendations listed above, the owner of the apartment or home can ultimately get a fairly even and beautiful coating. However, to reconcile such a finish, unfortunately, it will be earlier than if the ceiling was previously cleaned.

Therefore, before making a decision on whitewash without removing the old layer, it is worth thinking carefully. Lime holds on the ceiling quite firmly. Therefore, if the surface is finished, to apply a new layer without removal of older still has some meaning. But the chalk is removed from the ceiling very easily - just with the help of a rag and water. Therefore, in this case, it is more expedient to clean the surface.

A huge variety of materials for the finish finish displaces the old ways to repair, and the limestone whims applies no longer as wide as it was 50 years ago. But this proven generation method is fully consistent with the expression "cheap and angry". If you plan to beat the walls, ceilings or borders in the garden, read what properties the harated lime has, how to make it properly, calculate the solution consumption and apply on various surfaces.

Lime is not the easiest to use the material. However, its niche in the market of building materials it takes pretty firmly and very reluctating positions. Given all the advantages and disadvantages, in certain cases, the use of limeplains is appropriate, and sometimes it is more appropriate to choose another method.

Budget finishing material

Important properties of lime blots

Everyone known since school bench lime in chemistry textbooks is called calcium oxide. For whitewash, it is used to lime hawed, that is, reacted with water. If you say a chemical language, harated lime is a strong base - alkali. It has good disinfectant properties, because the aggressive alkaline environment has a detrimental effect on fungus, pest insects and other unwanted liveliness.

Lime-made whitewashing is not afraid of wet air, does not crack and does not be covered with bubbles. In addition to resistance to high humidity, the walls treated with this substance have resistance to temperature differences.

Powder Pushonka

For whitames it is not necessary to wash off the existing coating, it can be applied to the old finish. Moreover, if a mesh of small cracks was formed on the surface of the wall or ceiling, the treatment with a solution of hazed lime would strengthen the finish and extends its service life.

The cost of lime for blissing in stores does not compare with the price of other finishing materials. This is due to the fact that the production process is very simple - this is an elementary firing of lime rocks in the furnace. The raw material is a penny, therefore the price of the product is low. The thirty-tilogram bag costs about $ 2.

Where and why it is advisable to use lime

The properties of the antiseptic and fungicide make the lime of the leader among the finishing materials for raw and cold premises: cellar, shed, garage, basement and them like. It is used for walls and ceilings. The weather resistance of the substance allows it to be used for plain facades.

Recordsmen on the use of lime for blissing and other tasks - dackets. Here it is applied in full swing. It is accepted to break the walls both from the inside and outside, add a delayed lime into the soil to change its acid-alkaline balance, process the trunks of trees to protect against insects and animals, borders - for beauty.

Beat trees from pests

In those rooms, where practicality comes to the fore, and not aesthetics, and also matters the financial side of the issue, also apply the solution of lime to cover walls and ceilings. It can be observed in the entrances, on the staircases, in common corridors, lobby.

It is quite appropriate to bother the ceiling in any residential room. In schools, hospitals and other institutions still applies a lime solution for wall decoration. After drying, the calcium hydroxide becomes safe, does not emit any harmful substances into the air.

Buying lime - what to take and how much

Before going to the store, you need to find out what lime to buy - hated or smashed, how much it is required and what other components will be needed. It will save from a repeated trip to the Stroymarket, if suddenly the solution will be not enough or its properties will not meet your requirements.

How to cook hated lime with your own hands

As you already understood, harated and smaller lime are absolutely different substances that combine only the consonant name and the presence of calcium. For household repairs, it is used to hated lime. It is sold for a swim in any construction store or an agricultural department.

Kiphel - lime

However, there are often the situation when the farm has a fairly large stock of negoneary lime and it is advisable to use it, and not buy a hawker. In this case, it can be independently repayable, especially this chemical process does not require the skills of conducting such experiments in the laboratory.

So, how to cook lime for whitewashing from a closure of a lump "boiler". First you need to worry about personal protection. As you will deal with a rather aggressive alkali, take care of eye protection (glasses), respiratory organs (respirator), open skin (closed clothes and gloves). Do it you need in the air.

You will need a deep container, such as a bucket and tool for mixing - by tradition - a stick. The list of ingredients is also short:

• lime commercials Negarent;
• water.

Process of quenching

Water should be cold, this is the only condition. The proportion will remember even the first grader - 1: 1.

Step-by-step instruction:

1. By 1 kg of calcium oxide take 1 l cold water.
2. All this is connected in the tank and mix. Almost instantly you can observe the beginning of a powerful chemical reaction with the allocation of a large amount of heat. When the mixture, the mixture sometimes heats up to 150 degrees, not in vain the substance in the people was called a boiler - the solution literally boils.
3. When the reaction stops, heat and gas will stop stand out, the lime can be considered "Pushonka", that is, hawed. However, it is not suitable for blissing.
4. The solution must be carried out for 2-3 weeks under the lid in a dark cool place.

Solution proportions and square

To proceed to whitening lime with your own hands, you need to prepare at least such a set of materials:

• pushonka in powder or lime paste;
• water.

Packing Pushonki.

In addition, all sorts of excipients are often added to the whims, which gives it certain properties. The basic solution is prepared in proportion of 1: 3. Each kilogram of fluffs take 3 liters of water. As a result, 4 liters of solutions can be prepared from 1 kg of substance.

The lime consumption of 1 m 2 when parsing directly depends on the type of surface to which it is applied:

• The biggest flow rate is about 1 l of a ready-made solution to a square, will leave when packed with raw brickwork.
• A smooth prepared surface involves about 0.5 liters per square meter of the square.

Preparation of the room

Another criterion that is reflected in the consumption is a paint tool. More often use a conventional flat brush or round - maclove. These tools are uneconomical, the mass is applied with a thick layer, droplets and drops can be formed. The spray gun allows you to significantly reduce the consumption of the material and the time of operation. Often, instead of the collapral, the vacuum cleaner with the reverse blowing and even manual sprayers for trees are adjusted.

How to calculate the amount of puffs and water

Before breeding a delayed lime for whitewash, you need to perform some calculations. The approximate calculation of the flow is as follows.

First you need to calculate the walls of the walls and the ceiling that it is planned to be bold. For example: room 3 at 5 m, the ceiling height is 2.5 m. It was decided to treat the ceiling with a lime pavement and a part of the walls from the middle of the height to the ceiling.

Wall area: (3 * 2.5 + 5 * 2.5 + 3 * 2.5 + 5 * 2.5) / 2 \u003d 20 m 2.

Ceiling area: 3 * 5 \u003d 15 m 2.

Total area: 35 m 2.

Solution of the desired consistency

Based on the average flow rate of 1 l of a solution of 2 m 2 of the surface, it is easy to calculate the required amount for a whitewash - 17.5 l of a survey solution. You can round up to 18, and better - up to 20, because the average consumption is a flexible concept.

That is, 20 liters of mortar takes, and this is 5 kg of harated lime in powder. It is worth noting that the finished limestone dough that is sold in construction stores is divorced by the same proportion, which means the calculation is true for him.

Teaches leaves tracks

Additives to increase durability and flaws

Since lime is applied in construction for a very long time, there are a lot of "folk recipes" and methods that improve the properties of this substance. Still, modern water-making paints appeared not so long ago, and the folk craftsmen were forced to engage in chemistry right at their cottage or at home.

The first problem that is solved by adding the secret ingredient to the limestone solution - neaming. The dried surface has a taste of all and everyone who touches it. What to add to lime to not grip? This ingredient is in every home - a cook salt. It has a good fastening effect. 100 g of salts are added per liter of the solution.

Salt - so as not to smear

Another problem, especially when using spins for outdoor work, is a rapid washout with water. It has long been known that adding to lime in order not to be washed off - the fat component is introduced into it - Olif. Olife pushes water and allows the whitewash to serve longer. Proportion 1:10, 100 ml per liter of solution.

Practice the addition of household soap, grated on a large grater, PVA glue, wallpaper glue, acrylic primer. All this is done in order to ensure the maximum clutch of whitewings with the wall, eliminate its bloating and bubble.

Olife - not to wash off

White color is not the only possible

In order for the lime coating is not yellowish, an ordinary sink is added to it - methylene blue. It will take 10-20 g per liter. The whitewashed ceiling will become snow-white. But sometimes there is a need to obtain a lime solution of other colors. You can't call this mass by whitewash, and not every dye is suitable. Using only those pigments that are resistant to alkaline medium - mineral, but in no case are not organic.

Pigments that are used for limestone colors:

• ocher (yellow shade);
• umbra (greenish-brown);
• surik (orange);
• mummy (red-brown);
• chromium oxide (green);
• titanium dioxide (white);
• lithopon (white);
• ultramarine (blue).

Pigments use pigments

To prepare any good quality paints, it is not recommended to add a pigment in pure form - powder. It is pre-bred by water until the pasta is obtained. Then pigment paste gives about 24 hours. And only after that, the dye can be added to the solution. This is caused by the fact that pigment grains are often poorly dissolved and can reach for a brush, forming ugly colored stripes.

How to apply the composition to the surface in all the rules

Instructions, how to bother lime walls, look very diverse. The thing is that each master has a limestone recipe, its own tool, which means its own technique. But you can try to combine the fundamental moments into one algorithm. It turns out a universal method that everyone has the right to supplement or correctly correct depending on the situation.

For ceiling suitable roller

Does the surface preparation need

If the task is to quickly beat the walls and the decorative side of the question you do not care, the stage of preparation can be completely skipped at all. In fact, you can play directly on top of other coatings, not experiencing that the result will not meet expectations. But if the walls are covered with glue paint, then it is necessary to remove it.

If the speed is not your priority, then it is better to prepare the surface to apply a lime solution. So the result will be more neat. They wash off the old whitewash, the swollen places on the plaster are removed, sandwiched, put off. The same concerns cracks if they are.

Preparation of the ceiling to whitewash

As a primer uses conventional water. The surface is slightly wetted for better contact. And if there is one or more additives listed above in the mixture, then adhesion will be even better.

It is important to protect all the other surfaces from random limeths. All furniture, if it can not be taken out of the room, the floors and the walls are wrapped with a plastic film. An employee must put on a protective suit, mittens, glasses and a mask for personal protection.

Several secrets of uniform application

The application process does not represent a special complexity. The brush or the maclove is dipping into a container with whitewash, the solution is applied to the walls or ceiling with a thin layer. For the ceiling it is better to use a tool with a long handle. It can be made it with your own hands. This will facilitate the work and relieve from the need to climb on unstable designs from tables and chairs.

Direction of the movement of the brush or roller

They put the blots in several layers - 2-3. Each layer should be applied perpendicular to the previous one. So the coating will be more uniform, there will be no divorces and thickening. In the corners there are often nebened sections. In these places it is better to walk with a brush again.

Between the application of the layers, it is necessary to withstand the time interval. The previous layer must completely dry. This will happen much faster if layers do thin. The thinnest and uniform layer will be used when using an electric pulverizer. The lime mixture is poured into the tank and sprinkles on the surface with tiny drops. This eliminates the appearance of divorces.

Kraspopult - Solving many problems

Despite the fact that the process of blissing walls and ceilings with lime is not much labor, for the time you encountered this, it may seem an impracticable task. Especially when it comes to a high ceiling or extensive scope of work on large areas. It's never too late to turn to the master - a professional professional. He will easily fulfill this work qualitatively and much faster than the novice.
