characteristics, price, how to choose? + Videos and Photos Lime paint painting: characteristics, price, how to choose? Among the huge number of types of paints, lime paint has rightfully taken pride of place. The peculiarity of this composition is that after applying the paint, a layer with looseness is formed, which has a high vapor permeability of air.

It is used for facades, painting cement-lime plaster indoors and outdoors, as well as for surfaces that were previously painted with the same paint. For the facade, it is used due to the fact that it perfectly tolerates temperature changes, humidity and other negative environmental influences. This composition has found widespread use due to its low cost.

But there are a number of nuances that relate to work. If you do not add salt or drying oil in time when applying paint and varnish, then after drying, the surface will stain clothes and hands. In this article, we will look at what this paint consists of, as well as how to make it yourself.

Briefly about the paint

This composition, created on the basis of limestone, is classified as a type of mineral paints. From this it follows that the pigment in this composition is crushed minerals.

From the name it is easy to understand that the binder is slaked lime.

Sometimes it is added to the solution in the form of limestone milk. To increase the water-holding capacity, kitchen salt, aluminum alum and sodium chloride should be added during the manufacture. You can also get lime paint for interior work if you add inorganic pigments. Mostly the color range of such compositions is light.

I would like to note that it is short-lived in itself, but due to the process of carbonization of the main component, performance characteristics will improve over time. It is prohibited to paint on cement plaster. The mixture is considered cheap, affordable and is often used for facade decoration and restoration work. Limestone staining can also be done inside.

Surfaces for treatment with this compound can be as follows:

  • characteristics, price, how to choose? + Videos and Photos Plaster.

  • Concrete.
  • Brick.
  • Stone.

The only thing that cannot be painted with lime paint is metal. It is interesting that such paint can be bought ready-made, or you can cook it yourself.

Naturally, the first option is many times easier, but if you have a limited budget, you can do it yourself, and the result will be no worse, especially since it is not difficult.

Many types of lime-based formulations can be found commercially. A popular option is Tikkurila Finngard paint, which is considered a lime paint for exterior and interior use. It is used for painting cement-limestone plaster. The shades of the paint are light, but color can be added if desired.

Water is used as a thinner, and therefore the paint can be safely called safe.It dries very quickly and can withstand temperatures from -60 degrees to +55 degrees.

What about DIY paint? And how to make it?

Do-it-yourself lime paint

In fact, the manufacturing process is not as complicated as it might seem at first glance. The most important thing is to prepare everything you need and strictly follow the instructions.

In order to prepare 10 kg of the mixture, you will need:

  • 1500 grams of lime.

  • 100 grams of drying oil (combined).
  • 100 grams of salt (cooked only).
  • Plastic container for mixing components (bowl, bucket).
  • Water.

And now it remains to follow the instructions:

  1. Pour the measured amount of lime into the mixing container.

  2. Fill it all with 8.5 liters of water.
  3. Stir well.
  4. Add the indicated amount of salt and drying oil.
  5. Stir well again.

As for the salt, it should be administered separately from the other components. It should not only be taken to sleep, but administered as a saline solution. If you need to whiten the mixture, add a little blue to the solution (methylene blue). Then stir the solution thoroughly and strain the resulting mixture.

But the recipes themselves are quite a lot.

For example, someone makes a paint as follows: 3 kg of limestone "dough" is diluted with five liters of water, add 100 grams of salt and mix everything well. After that, the mixture must be filtered through a fine-grained sieve, and water must be added to make 10 liters of paint, and then 400 grams of pigment must be added. Another recipe: dilute 5 liters of water for 1500 grams of quicklime and add 500-1000 grams of natural drying oil. Strain this solution and add the remaining water. In this case, you will also get 10 liters of paint, to which you can add dye.

One of the varieties of lime paint is a composition made on an adhesive basis. To prepare this type of paint, chalk must be diluted with water and a paste is made. After that, the solution should be infused for a day, and after this time it is stirred and the density is checked.

Use the following methods to check density:

  1. Stick. Dip the stick into the bucket containing the solution.

    You can use the composition if the mixture will not just fall off the stick, but flow off in a stream (viscous) and will not be interrupted like honey.

  2. Glass. Set the glass vertically, apply a drop of solution to the surface. If the consistency is what you need, the trace of the drop will be no more than 3 cm.

If you are not sure that you can correctly determine the viscosity, use a viscometer.

It is a small scoop-shaped vessel with a capacity of approximately 100 ml. She also has a long narrow nose, the diameter of which is 4 cm. Solution or paint will flow through it.

As for the shade of lime paint for outdoor use, in the original version it is white, even a little grayish, that is, like limestone. If necessary, you can always tint the paint.

To do this, buy a suitable dye and add it to the mixture. In this case, it is very important to strain the introduced pigments, and the overall consistency should be milky.

Please note, that when using a lime composition for whitewashing, it should be borne in mind that the tinted solution will become lighter as it dries.

For this reason, before deciding on a shade, carry out a test staining. To do this, apply a thin layer of paint to the glass, and after drying, consider the finishing shade.

Share one trick for improving your limestone paint composition? If you add 10% bone glue to the composition, then the ceiling painted with such a composition will not fall off and crumble. When adding glue to the paint, check the fixation of the whitewash. This can be done in a proven way - apply paint to the glass with strokes.

Advantages and disadvantages of lime paint

Still, it is not in vain that such solutions were popular with our grandfathers and grandmothers. It can be said that this was the simplest method of making the room fresh.

For this reason, among the benefits, there will not be as much good as other materials, since this composition is older.

Although there are few advantages, they are still there:

  • characteristics, price, how to choose? + Videos and Photos Low cost, as this paint is considered one of the cheapest.
  • There are no toxic substances in the composition, and therefore it is rightfully considered safe and environmentally friendly.
  • It can be used for various types of surfaces.
  • Limestone paint is a vapor permeable paint.

  • It is resistant to high and low temperatures.
  • Resistant to moisture.

All the pluses end there. It would be dishonest not to mention the disadvantages, which are fragility and peeling of lime particles after drying. The surface treated with this composition does not look the best way.

Surely many of us have come across such walls and are well aware that it is easy to smear clothes and hands about them. But this problem can be solved if you add salt and drying oil to the composition. This paint option is not bad for storage and utility rooms. But if you are doing repairs in a residential building, then it is better to spend a little more money and buy better quality paint and varnish materials.

Preparatory work

The process of painting with lime paint is quite simple.

The composition can be worked with a roller or a paint brush, but the use of a spray gun is also allowed. Before you start painting, prepare the wall. In principle, the preparation is not much different from the standard case - clean the surface of dirt and dust, remove all protruding parts and irregularities.Use a similar repair mortar. Inadmissible cement compositions.

The base does not need to be primed. If you suddenly find moss on the surface, carry out work to remove it, and the same applies to oily walls.

Good advice! Remove old organic paint before application.

If lime paint has already been applied to the surface, then remove only those layers that had time to peel off or weakly adhere. For this, it is convenient to use a copper or stainless steel brush.

You can also rinse the surface with a powerful pressure of water, but then you will have to wait for the walls to dry.

Consider the working conditions as well. For example, coloring is allowed if the temperature is above +5 degrees. If the weather is windy but warm, then the surface must be moistened both before and after staining. Staining in rainy weather is prohibited.

It is advised to work when it is cloudy, since the direct rays of the Sun will not fall on the surface. If you paint the walls indoors, the ideal temperature is +15. . + 20 degrees.

Painting

Let's take a look at the process of painting with lime paint on the Finnhard composition of Tikkurila.

It should be diluted with clean water before application. The proportions are as follows - a can of paint (25 kg) requires 16 liters of water. The use of paint undiluted is prohibited. Stir the mixture as often as possible when painting, as the stony particles are heavy and will constantly sink to the bottom.

Staining with lime-based paint at least 3 times to create 3 layers, with a brush or a brush.

In this case, the application interval should be equal to the drying time of the layer, that is, the layer is dry - a new one has been applied, and so on. Before applying each layer, the wall must be moistened both before and after.

Please note that for a solid surface, stock up on a sufficient amount of lime paint from the same manufacturer.

The boundary between the surfaces, which is covered with compounds from different manufacturers and batches, must be treated with a solution - 1 part of the old batch and 1 part of the new one. Everything needs to be planned so that the junction is in the most imperceptible place for human eyes.

If the surface is small and solid, then the work must be done continuously. The end of the work falls precisely on the corners of the room, as well as on the borders with the door, windows and balcony. You can easily get an even application and good results if you avoid overcoating in small areas. Light pressure is ideal. Remember that if there are fluctuations in temperature and humidity in the room, the hue and color in general will change in places.

Further hydration will darken the color.

When it's over, rinse the tools thoroughly with running water. You can use a mild vinegar solution and then rinse the instrument with running water.

Conclusion

Now you know what lime paint is. This is a special composition that our ancestors began to use long ago.

It is based on water, lime and dye if desired. Due to the instructions, you now not only know how to make this composition with your own hands, but also how to paint. It is interesting that even someone who is not a professional in the construction business can work with this paint. This is another advantage of such a simple yet effective lime-based paint.
