Applying whitewash to the walls. We prepare the tree for whitewashing and properly breed lime Hydrated lime for whitewashing trees

Whitewashing walls with lime is a cheap, easy and very popular way to decorate a room. He showed himself perfectly when processing pools, basements, corridors. It is necessary and important to know how to extinguish lime at home, because the quality of the decorative finish depends on it.

Before the beginning construction works lumpy lime must be properly extinguished. The end result of this reaction will be fluff lime of a certain consistency.

How to extinguish lime for whitewashing walls:

1. Wear overalls, gloves, a respirator and goggles.
2. Pour lumpy raw materials into a metal stainless container.
3. Pour cold water, proportion 1:1. There will be a chemical reaction with a temperature surge of more than 100 degrees, boiling and splashing.
4. In time, the reaction takes place in half an hour. Then the solution is well stirred with a wooden stick - until a homogeneous mass is obtained. After 30 minutes, when the violent reaction has passed and everything is stirred, the solution is left for a day to ripen, stirring occasionally.
5. The whole process takes place on fresh air or in a ventilated area.

White walls: how to extinguish lime?

The resulting composition is used for any purpose. If you add a little water to it, you get a lime dough, it looks like sour cream. Add even more water - milk of lime. The intensity of the applied layer of whitewash depends on the consistency of the lime.

How and in what proportions to extinguish lime?

There are several methods for slaking lime. The main thing is to do it right, otherwise the quality of the final product will suffer.

Lime is divided into three groups:

• quickly extinguished - up to 10 minutes, half of the container is filled with lime, water is added to the top. Stir gently while adding water in small portions. At the end, pour into another container;
• medium extinguishing - up to 20 minutes, the whole process is the same as in the first case. The proportion of lime to water is 1:1, but no more water is added;
• slowly extinguished - more than 25 minutes, a little more than half of the container is filled with quicklime, water is poured in a thin stream. If the stones begin to crack, then the extinguishing has begun. Water is added in small portions until a lime paste is obtained.

After chemical reaction not all pieces decompose, in which case they are thrown away. There is another important point: after slaking lime, it is necessary to ripen in a cool and dark place 3 weeks, then the whitewash will be perfect.

Whitewashing with lime is a generation-proven method of treating the surfaces of walls and ceilings. Despite the range of modern building materials, lime does not leave store shelves. What is the secret?

Whitewashing with lime or chalk: what to choose?

Whitewashing as a way of finishing the surfaces of residential premises is becoming less and less popular. Modern materials are increasingly appearing in our apartments, and there is no longer any particular desire to mess with the bleaching solution. But, nevertheless, there is still a demand for lime and chalk whitewash. This finishing method is widely used in educational and medical institutions, in utility rooms, etc.

Whitewashing can also be found in apartments, for example, on the ceiling in the kitchen or bathroom. Quite often, a bleach solution is used to finish a garage, a barn and a cellar in home gardens. And if you go outside the city, then in the villages you can still find neat white houses, in which, of course, the stove occupies a central place. Whitewashing the stove with lime is still relevant today.

If there is a need for whitewashing, then first of all you need to choose the material on the basis of which the bleaching solution will be made. The most common options are chalk and lime. Of course, each of the options has its positive and not so properties. What do you know about them? Nothing? Then meet:

Lime is a material that is obtained in the process of roasting carbonate rocks. It is used both in construction and for obtaining various chemical compounds. Hydrated lime is used for bleaching, which is obtained by combining lime powder with water. It has the following positive characteristics:

• affordable and low cost of the material;
• has bactericidal properties;
• resistant to temperature fluctuations;
• moisture resistant;
• able to tighten small cracks;
• adheres well to brick, stone, wood and plaster.

Whitewashing with lime also has negative points:

• possible defects (streaks, stains, stains);
• there is a risk of burns.

Since lime is a sodium alkali, precautions must be taken when working with it to protect your health.

Chalk is a common and familiar material of natural origin. Advantages of chalk finish:

• affordable price;
• environmental friendliness;
• deep color white;
• easy to wash off - easy to remove a layer of white;
• simplicity and safety in work.

Disadvantages:

• easy to wash off - not suitable in a humid environment;
• possible defects (stains, streaks, bubbles, etc.).

How to extinguish lime for whitewashing correctly and safely?

In the event that the lime turned out to be more suitable option to finish the necessary surfaces, you need to familiarize yourself with the rules for its preparation and extinguishing. You can buy this alkali in a hardware store in slaked (powder, dough) and quicklime(lumps). In the first case, it can immediately be added to the solution, and in the second case, it can be preliminarily extinguished.

Before extinguishing lime for whitewashing, you need to make sure that all precautions are observed and there is no danger to health. For safe work necessary:

• put on overalls and rubber gloves;
• protect your eyes with special goggles, and your nose with a respirator;
• extinguish lime only in metal containers;
• choose a well-ventilated area for this procedure.

If lime comes into contact with skin, rinse immediately. large quantity running water within 15 minutes, and then be sure to consult a doctor.

After following all the precautionary procedures, you can begin to slake the lime. Quenching is a chemical reaction in which lime reacts with water. As a result, you can get fluff (powder) or lime dough, which will depend on the amount of water used.

To get fluff, you need to take 1 part of lime and 1 part of water, i.e. 1 kg of lumps of lime per 1 liter of water. Lumps are placed in a clean deep container, which are then filled with cold and clean water. Reacting, the lime heats up very much, which is accompanied by hissing and splashing. It will take about 30-40 minutes before the lye settles down. After that, it must be stirred wooden stick. As a result, after evaporation of moisture, a powder will be obtained.

Lime dough is a plastic mass, for the preparation of which you need 1 part of alkali and 3 parts of water. The further process is not particularly different: water is added in small portions to a container with lumps of lime and gradually stirred. During the reaction, moisture evaporates, but its content in the final product will be greater, which will make it possible to obtain a pasty consistency. Strengthen with a test cement-sand mortars and prepare solutions for plastering works.

How to dilute lime for whitewashing at home depends on the form in which the alkali is present, it can be prepared according to several recipes. Mandatory ingredients in all formulations are water and table salt, so you should check their presence. And then we choose a recipe, adapt it to required volume and prepare a bleaching solution, the approximate consumption of which is 0.5 liters per 1 m2 of surface.

Recipe 1. Fluff - 400 g, water - 600 ml, table salt - 5 g, drying oil - 0.3 tbsp. Mix all ingredients thoroughly and pass through a sieve to remove lumps. To give a bluish tint to the resulting solution, you can add ultramarine - 20-25 g.

Recipe 2. Dough - 3 kg, water - 10 l, table salt - 100 g. The dough is diluted in half the volume of water and milk of lime is obtained. Salt is diluted separately in 1 liter hot water, is added to milk and thoroughly stirred. Coloring compositions are also soaked separately in water and gradually poured into the solution. Before use, the bleach mass is brought to a volume of 10 liters by adding the required amount of water.

I will note right away: I am not going to prove the usefulness or futility of this undertaking. On the Internet, two camps have long been formed, which are constantly fighting among themselves, proving points of view to the point of losing momentum.

Someday I will study the issue, but not in this article. It is intended for those who want to learn how to dissolve lime for whitewashing trees, and get an idea how to do it the right way, according to science.

Why whitewash trees?

Most gardeners, answering this question, will say: "to protect trees from sunburn." This is true. But there are still factors that become whitewashed.

Frost protection

Frost cracks are damage to the bark, resembling deep cracks. AT severe cases they can reach the middle of the tree, which leads to its death. They are formed during fluctuations in day and night temperatures in winter time especially in February.

During the day it warmed up to 1 0 C, and at night it was -15 0 C - a phenomenon familiar to the regions of Russia. The bark of a tree, heated by sun rays during the day, cools sharply at night. This is equivalent to immersing hot glass in cold water.

Whitewashing a tree leads to the fact that the bark warms up and cools evenly. We remember from physics that dark color absorbs solar heat, light - reflects. This property is used in our case.

Pest extermination

Even slaked lime is an alkali that kills most insects, especially their larvae. Many diseases garden trees caused by these pests, and whitewashing reduces risks, reduces the consumption of chemicals, and preserves the crop.

Inexperienced gardeners complain that whitewashing does not help. Like, there is no difference between the processed wood and the unprocessed. Yes it is possible. But only if you take a brush and apply lime mortar without proper preparation. I will talk about it below.

sunburn protection

This factor causes numerous disputes on the forums. People working in forestry say that sunburn found only on some breeds coniferous trees and never - on deciduous.

Maybe this is so. But it's better to be safe. In theory, whitewashing can protect the bark from burns as well as frostbite. The same principle of intense reflection of the sun's rays works.

Whitewash contraindications

Some gardeners consider lime a panacea for all ills and wield a brush right and left. Thus, they make a gross mistake - not all trees can be whitewashed.

If you have a young garden, and the trees are not older than two years, it is better to refuse the event. The tender bark of young seedlings is easily damaged by aggressive alkali. It does more harm than good.

Preparing a tree for whitewashing

At this point, I will elaborate. Many gardeners make a mistake here, or rather, they do not prepare the tree in any way. The result is pests, burns, and trouble-sadness.

Remember. It is impossible to whitewash a tree without preliminary cleaning and disinfection. Yes, it will be beautiful. But no benefit.

Before cleaning, take plastic wrap and spread around the tree, close to the trunk. This is necessary so that pests and debris do not enter the soil. Then proceed according to the following scheme.

1. Prepare wooden or plastic scrapers (do not work with metal tools).
2. Examine the surface of the trunk and main branches, pay attention to cracks.
3. Carefully remove the falling bark, mosses, lichens.
4. Cover deep cracks and hollows with garden pitch.
5. Trim the tree if necessary.
6. Treat the barrel with a disinfectant solution.

Disinfection is best done with a sprayer or trigger. In this case, the solution will penetrate even the smallest cracks. With a brush, this effect cannot be achieved.

After disinfection, the film must be carefully collected, taken away from the garden and burned.

Disinfectant solutions

Most often in gardening, a 3-5% solution of copper or iron sulfate is used. It is prepared like this:

• take 300 g of powder (for a 5% solution - 500 g);
• pour in the same amount of hot water;
• after dissolving the vitriol, bring the volume of water to 10 liters (you can use warm or cold);
• mix thoroughly with a wooden stick.

Spray the main trunk and skeletal branches with this solution. If you missed the time and the tree began to bloom, make a 2% solution.

If in the process of inspecting a tree you find colonies of mosses or lichens, vitriol will not help. Treatment with salt solutions is necessary, which can be prepared by dissolving one of the following ingredients in 10 liters of water:

• food salt - 1 kg;
• urea - 600 g;
• nitroammophoska - 650 g;
• potassium carbonate - 550 g;
• potassium chloride - 350 g.

These solutions are applied to moss growth sites or added to lime mortar.

If you are an ardent opponent of chemistry and do not want to poison the garden, you can use a wood ash solution for disinfection. It is prepared according to the following recipe:

• take 3 kg of ash;
• add 5 liters of water;
• bring to a boil;
• cool, add 50 g grated laundry soap;
• mix thoroughly.

Spray the trunk and branches of the tree.

Trees can be bleached 3 days after treatment. If it rained at this time, repeat the disinfection.

How to properly dilute lime for whitewashing?

In stores you can only find quicklime. These are white stones, less often sand, which have a strong alkaline reaction. When interacting with water, a strong release of heat occurs, and three types of solutions can be obtained:

• fluff;
• lime dough;
• lime milk.

What you get at the end depends on the ratio of quicklime to water. According to technology, you first need to get fluff and only then prepare a solution for whitewashing.

Fluff recipe

Use caution when handling quicklime. During interaction with water, the temperature rises to 150 0 C, and the solution itself boils and “splashes”. If you're not careful, you'll get chemical burns eyes or skin.

Therefore, work with gloves and protect your eyes from lime. Step by step recipe next:

• take a deep container (a bucket will do);
• pour 2 kg of quicklime;
• carefully pour in 2 liters of water;
• wait for the violent reaction to pass;
• Gently mix the contents until smooth.

You can take a different amount of lime. The main thing is to keep the ratio 1:1 or 1:1.5, where the first value is quicklime.

How to make a whitewash solution

If you simply dissolve the fluff in water, the whitewash will be washed off by rain in a month. Therefore, I recommend whitewashing trees with the following solution:

• 2.5 kg fluff;
• 9 liters of water;
• 60 g (3 tablespoons) flour paste.

Mix everything thoroughly and apply to the trunk with a brush. Instead of a paste, you can add 1 kg of clay.

Note. You should get a creamy mass (milk of lime). A more liquid solution will roll off the bark, a thicker one will not stick.

Lime milk is prepared in a ratio of 1:3. If you want to whitewash young seedlings, make a 1: 4 consistency or use water-based paint.

When is the best time to bleach trees?

It is believed that the trees need to be whitewashed in the spring. This is not entirely correct. At this time of the year, the main whitewash is carried out, but it must be repeated in the fall, when preparing the tree for wintering.

Whitewashing in the spring is carried out after the snow melts. In the central regions of Russia, this is the end of March - the first half of April. In the south - the beginning of March. The air temperature during this event should not be below 5 0 C. But you should not delay whitewashing either - you need to have time to disinfect and whitewash the trees before the foliage appears.

If you hesitate, the soil will warm up, pests will crawl out of it, the procedures will be in vain.

Whitewashing in the fall is carried out after the foliage is dropped. The air temperature should not be below 4 0 C. The process is the same as when processing a tree in the spring - first clean the dead bark, treat the cracks with garden pitch, disinfect, only then whiten.

Whitewashing in the summer is acceptable if you notice that the lime has been washed away by the rains. The best time for this - early morning, until the heat began. No advance preparation is required.

I think I told in detail how to dilute lime for whitewashing and about the technology for processing a tree trunk. If you have any questions - write in the comments or social networks.

We prepare the tree for whitewashing and properly dilute the lime

Huge variety of materials finishing replaces the old methods of repair, and lime whitewashing is no longer used as widely as it was 50 years ago. But this generation-tested method is fully consistent with the expression "cheap and cheerful." If you are planning to whitewash walls, ceilings or borders in your garden, study the properties of slaked lime, how to properly prepare it, calculate the consumption of the solution and apply it to various surfaces.

Lime is not the easiest material to use. However, it occupies its niche in the building materials market quite firmly and is very reluctant to lose ground. Given all the advantages and disadvantages, in certain cases, the use lime whitewash is appropriate, and sometimes it is more appropriate to choose another method.

Budget finishing material

Important properties of lime whitewash

Lime, known to everyone from school, is called calcium oxide in chemistry textbooks. For whitewashing, slaked lime is used, that is, it has reacted with water. In chemical language, slaked lime is a strong base - alkali. It has good disinfecting properties, because the aggressive alkaline environment adversely affects the fungus, pests and other unwanted animals.

Lime whitewashing is not afraid of moist air, does not crack or blister. In addition to resistance to high humidity, walls treated with this substance are resistant to temperature extremes.

Fluff powder

For whitewashing, it is not necessary to wash off the existing coating, it can be applied to the old finish. Moreover, if a network of small cracks has formed on the surface of the walls or ceiling, treatment with a solution of slaked lime will strengthen the finish and extend its service life.

The cost of lime for whitewashing in stores cannot be compared with the price of other finishing materials. This is due to the fact that the production process is very simple - it is an elementary firing of lime rocks in a kiln. Raw materials cost a penny, so the price of the product is low. A thirty-kilogram bag costs about $2.

Where and why it is advisable to use lime

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

The record holders for the use of lime for whitewashing and other tasks are summer residents. Here it is in full swing. It is customary to whitewash walls both inside and out, add quicklime to the soil to change its acid-base balance, treat tree trunks to protect against insects and animals, curbs for beauty.

Trees are bleached from pests

In those rooms where practicality, not aesthetics, comes to the fore, and also matters financial side question, lime mortar is also used to cover walls and ceilings. This can be observed at the entrances, on landings, in common corridors, foyers.

It is quite appropriate to whitewash the ceiling in this way in any living space. Schools, hospitals and other institutions still use lime mortar for wall decoration. After drying, calcium hydroxide becomes safe, does not emit any harmful substances.

Entrance decoration

Buying lime - what to take and how much

Before going to the store, you need to find out which lime to buy for whitewashing - slaked or quicklime, how much it is required and what other components will be needed. This will save you from a second trip to the construction market if suddenly the solution is not enough or its properties do not meet your requirements.

How to make slaked lime with your own hands

As you already understood, slaked and quicklime is absolutely different substances, which are united only by a consonant name and the presence of calcium in the composition. For household repair work slaked lime is used. It is sold by weight at any hardware store or department for Agriculture.

Kipelka - lumpy lime

However, situations are not uncommon when the farm has a fairly large supply of quicklime and it is desirable to use it, rather than buy slaked lime. In this case, you can pay it off yourself, especially this chemical process does not require the skills to conduct such experiments in the laboratory.

So, how to prepare lime for whitewashing from lumpy quicklime "boiler". First you need to take care of personal protection. Since you will be dealing with a rather aggressive alkali, take care to protect your eyes (glasses), respiratory organs (respirator), exposed skin (closed clothing and gloves). This must be done in the air.

Video: How to prepare a whitewash solution

You will need a deep container, such as a bucket and a stirring tool - traditionally a stick. The list of ingredients is also short:

• lumpy quicklime;
• water.

Quenching process

The water must be cold, this is the only condition. Even a first-grader will remember the proportion - 1: 1.

Step-by-step instruction:

1. For 1 kg of calcium oxide take 1 liter cold water.
2. Combine all this in a container and mix. Almost instantly, you can observe the beginning of a powerful chemical reaction with the release of a large number heat. When quenching, the mixture sometimes heats up to 150 degrees, it is not for nothing that the people called the substance a boiling water - the solution literally boils.
3. When the reaction stops, heat and gas cease to be released, lime can be considered "fluff", that is, slaked. However, it is not yet suitable for whitewashing.
4. The solution should ripen within 2-3 weeks under a lid in a dark, cool place.

Solution proportions and consumption per square

To start whitewashing with lime with your own hands, you need to prepare at least the following set of materials:

• powdered fluff or lime paste;
• water.

Fluff packaging

In addition, all kinds of auxiliary substances are often added to whitewash, which give it certain properties. The stock solution is prepared in a ratio of 1:3. For every kilogram of fluff, take 3 liters of water. As a result, 4 liters of solution can be prepared from 1 kg of the substance.

Lime consumption per 1 m 2 during whitewashing directly depends on the type of surface on which it is applied:

• The largest consumption is about 1 liter ready solution per square, will leave when whitewashing raw brickwork.
• A flat, prepared surface suggests approximately 0.5 liters for each square meter area.

Room preparation

Another criterion that affects the cost is painting tool. More often they use an ordinary flat brush or a round one - a maklovitsa. These tools are wasteful, the mass is applied in a thick layer, streaks and drops can form. The spray gun can significantly reduce material consumption and operating time. Often, instead of a spray gun, a reverse blower vacuum cleaner and even hand-held tree sprayers are fitted.

How to calculate the amount of fluff and water

Before you dilute slaked lime for whitewashing, you need to perform some calculations. An example cost calculation is as follows.

First you need to calculate the area of ​​\u200b\u200bthe walls and ceiling that you plan to whitewash. For example: room 3 by 5 m, ceiling height 2.5 m. It was decided to process the ceiling and part of the walls from the middle of the height to the ceiling with lime whitewash.

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

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

Total area: 35 m2.

A solution of the desired consistency

Based on the average consumption of 1 liter of solution per 2 m 2 of surface, it is easy to calculate the required amount for whitewashing - 17.5 liters of lime mortar. You can round up to 18, and preferably up to 20, because the average consumption is a rather flexible concept.

That is, 20 liters of solution are required, and this is 5 kg of slaked lime in powder. It is worth noting that the finished lime dough, which is sold in hardware stores, is diluted in the same proportion, which means that the calculation is correct for it.

Whitewash leaves traces

Additives to improve durability and combat imperfections

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

The first problem that is solved by adding a secret ingredient to a solution of lime whitewash is grinding. A dried surface tends to stain everything and everyone who touches it. What to add to lime so that it does not smear? This ingredient is in every home - table salt. It has a good bonding effect. Add 100 g of salt per liter of solution.

Salt - so that it does not smear

Another problem, especially when using whitewash for outdoor use, is the rapid washing off of the composition with water. It has long been known what to add to lime so that it does not wash off - a fatty component is introduced into it - drying oil. Drying oil repels water and allows whitewash to last longer. Proportion 1:10, 100 ml per liter of solution.

They practice adding laundry soap grated on a coarse grater, PVA glue, wallpaper glue, acrylic primer. All this is done in order to ensure maximum adhesion of the whitewash to the wall, to exclude its swelling and bubbling.

Drying oil - not to be washed off

White is not the only possible

To prevent the lime coating from becoming yellowish, ordinary blue is added to it - methylene blue. It will take 10-20 g per liter. The whitewashed ceiling will become snow-white. But sometimes it becomes necessary to get a lime mortar of other colors. You can’t call this mass whitewash, and not every dye is suitable. Use only those pigments that are resistant to an alkaline environment - mineral, but in no case organic.

Pigments that are used for lime paints:

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

Pigments are used to make

To prepare lime paints good quality, it is not recommended to add the pigment in its pure form - powder. It is pre-diluted with water until a paste is obtained. Then pigment paste let it brew for about 24 hours. And only after that the dye can be added to the solution. This is due to the fact that pigment grains often do not dissolve well and can drag on the brush, forming ugly color streaks.

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

Instructions on how to whitewash walls with lime look very diverse. The thing is that each master has his own recipe for a lime mixture, his own tool, which means his own technique. But you can try to combine the fundamental points into one algorithm. It turns out universal method, which everyone has the right to supplement or slightly correct depending on the situation.

A roller is suitable for the ceiling

Is surface preparation necessary?

If the task is to quickly whitewash the walls and the decorative side of the issue does not really bother you, you can skip the preparation stage altogether. In fact, you can whiten directly on top of other coatings without worrying that the result will not live up to expectations. But if the walls are covered with adhesive paint, then you need to remove it first.

If speed is not your priority, then it is best to prepare the surface for the application of lime mortar. So the result will be more accurate. Wash away old whitewash, swollen places on the plaster are removed, sanded, puttied. The same applies to cracks, if any.

Preparing the ceiling for whitewashing

Plain water is used as a primer. The surface is slightly wetted for better contact. And if the mixture contains one or more of the additives listed above, then adhesion will be even better.

It is important to protect all other surfaces from accidental contact with lime. All furniture, if it cannot be taken out of the room, the floors and walls are hung plastic wrap. The worker must wear a protective suit, gloves, goggles and a mask for personal protection.

A few secrets of uniform application

The application process is not particularly difficult. A brush or maklovitsu is dipped 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 by hand. This will make it easier to work and eliminate the need to climb on unstable structures from tables and chairs.

Direction of brush or roller movement

Whitewash is applied in several layers - 2-3. Each layer must be applied perpendicular to the previous one. So the coating will be more uniform, there will be no streaks and thickening. There are often gaps in the corners. In these places it is better to walk with a brush again.

Between the application of layers it is necessary to withstand the time interval. The previous layer must dry completely. This will happen much faster if the layers are made thin. The thinnest and most uniform layer will be obtained using an electric spray gun. lime mixture poured into the tank and sprayed onto the surface in tiny drops. This eliminates the appearance of divorces.

Airbrush - the solution to many problems

Despite the fact that the process of whitewashing walls and ceilings with lime is not a big deal, for someone who has encountered this for the first time, it may seem like an impossible task. Especially when it comes to a high ceiling or an extensive amount of work on large areas. It is never too late to turn to the master - a professional in his field. He can easily do this work efficiently and much faster than a beginner.

Video: Quick repair cellars

A bar of laundry soap must be crushed into shavings, pour boiling water and stir thoroughly until completely dissolved. After complete cooling, 2 tbsp. l. lime.

In parallel with this, you can start slaking lime. This process is carried out with water strict observance the proportions described in the instructions on the package. As a rule, to prepare a solution for whitewashing the ceiling, it takes about 2 kg of lime to be diluted in 5 liters of water.

After adding a chilled soap solution to the resulting composition, it is necessary to thoroughly mix all the ingredients and add water in such a way as to completely fill the 10-liter bucket.

Lime mortar with salt

Another common and simple whitewash recipe is lime mortar with the addition of ordinary table salt. For its preparation, 1.5 kilograms of slaked lime are diluted in 4 liters of water.

In parallel with this, in another container, it is necessary to prepare a saline solution by diluting about 5 tbsp in a liter of boiling water. l. product. After complete cooling, the composition is added to lime and supplemented with water to the desired density.

Before applying to the surface

Regardless of the recipe used to prepare the lime mortar, it must be filtered before applying to the surface. To do this, the composition is passed through several layers of gauze.

If, when applied with a brush, traces of pile remain on the surface, then the consistency is too thick. You can fix the situation by adding required amount water.

If desired, the lime mortar can be supplemented with various pigments - chromium peroxide, or ultramarine. 300 g of dyes are enough for a bucket of whitewash.
