We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick

We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick To apply plaster on walls, it is not necessary to be the best specialist, but you need to be careful, maybe even pedantic ...

If you have purchased a new apartment or house where there is no decoration, then most likely what caught your eye is a plaster with gray spots, sometimes corners can be removed.

If there is no plaster, then the preparation work will need to be done by you.

Work in a new apartment

In most cases, when purchasing a finished home, you get an apartment or house with a basic layer of plaster. This is beneficial for a construction company:

  1. If there is no plaster in the room, then the company simply will not be able to rent the house. But whether there should be a finishing or preliminary finish is not indicated in the regulatory documents. The walls are plastered - the commission will accept the dwelling, as the conditions for delivery are met.
  2. "Rough" plaster helps to hide the unevenness of the brickwork, if rejected bricks or even halves were used.

IMPORTANT: looking at the wall it is difficult to notice all the irregularities, as well as defects in the application of plaster. Experts recommend pulling the line in three places: at the bottom of the wall, in the middle and at the top.

In this case, you will immediately notice gaps, places where you did not finish, uneven corners. Having discovered flaws, you can throw a scandal in a construction company, or redo everything with your own hands. In some companies, it is possible to completely abandon the interior decoration.

But if this is not possible and the result did not suit you, you will have to remove everything to the ground and carry out the work again. Do not forget about the primer (the adhesion of the wall and putty will be stronger) and beacons (will make the surface even).

Applying plaster on the wall

Features

When working in high-rise buildings, there is a very significant problem - rupture process. How everything happens: one master takes not one, but more apartments for work, makes a primer in all rooms or sprinkles plaster on the wall. Until he finishes these works, and returns to the beginning, everything will dry out, which will complicate further work.

To do the work better, more time is needed, but it is not always enough. It is best to putty those rooms that immediately catch the eye. To make them look more advantageous, plaster materials are often used for finishing work. The corners are simply smoothed out with the tools at hand.

Consider the features of applying plaster to a brick wall:

  1. Prepare the wall - measure it with a building level, use fishing line and plumb lines, determine the places of dips and curvature of the surface, determine the places where a layer of leveling plaster will be applied.

  2. Making the jointing. You can remove excess or deepen. To create shallow indentations, knock on the wall with a hammer.
  3. We put beacons and vertical posts, along which we will further navigate in the process of work.
  4. We saturate the walls well with water or a special solution.

    Don't neglect this step, especially if you have concrete walls.

  5. We lay plaster, level everything according to our lighthouses.
  6. We are waiting for drying and put the bulk of the putty, we carefully align everything according to our guidelines.
  7. Gypsum mixture or other finishing materials are used for finishing.

To speed up the work process, some grief specialists skip several steps, or use one composition for all types of work.

Tools for work

We need:

  • We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick - a 20 liter bucket or a special container;
  • - a spatula 20-30 cm wide, a trowel, wooden floats of different lengths, as a rule;
  • - level (regular construction or electronic), plumb lines, thick line (50-80 m), dowel nails.
  • - a drill and a special nozzle for mixing the solution.

If you have fallen off plaster, prepare a wooden board with a handle on which the mortar will be applied, which will then be applied with a spatula to the wall surface. This is especially useful when you are already applying the finish: it is easier to use a small amount of material from the falcon than to constantly bend over.

Features of the materials used

Before starting work, purchase a preliminary and finishing mixture, depending on the volume and quality of the finished walls.

Plaster putty is most often used as a finish.

Carefully read the instructions on how to make the solution correctly, what and how much to add. Add water, mix everything thoroughly and get about 70-100 ml of the finished mass. If you are a beginner specialist, then it is best to start with a not very noticeable wall.

It is best to prepare the solution using special tools, since it is quite difficult to do it with your hands and it is not a five-minute process in time.

Plaster application technology

The simplest is manual application, but now machine application wall plastering is widespread. These are quite expensive tools, so I can not afford all of them, especially if you need to putty several walls, it is not cost-effective. Now you can arrange a lease, or do everything the old fashioned way.

Highlights

Work is carried out in three different ways, which are best not to be missed:

  1. Spray ..

    .

  2. Coating with primer.
  3. Making a cover.

For flat surfaces, when there are no differences of more than 5 mm, the first stage can be skipped and go directly to the second.

First layer - spray

We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick Worker protection is very important at this stage and other surfaces in the room.

The employee must wear goggles with a mask or a respirator. Close all windows and doors with foil, preferably with an overlap.

To perform the work, a solution is needed, it should be similar in consistency to thick sour cream. The mortar will fill all cracks, as well as notches that we made intentionally. The solution is placed on a trowel or in a ladle and thrown onto the wall with sharp movements.

Throw on the wall from the same distance, remember that if you do this very diligently, the solution can fly in all directions. Covered all surfaces, wait a little for the mixture to set and dry a little. But, do not let it dry out, otherwise the next layer will not fit well.

Priming coat

The solution for applying the primer should be thicker than for spraying. In work, we need a spatula and a rule.

Using a spatula, throw in the solution, align with the rules.

Press the rules firmly against the guides you set earlier. Move only from bottom to top, do not forget to perform oscillatory movements on the sides so that the solution gets into all cracks, voids and irregularities that are still left after spraying.

If the wall is large, then divide it into several sections, putty one section, then another, do not forget to carefully make joints. It is best to wipe them again later.

Finishing coat or overcoat

Wait a little for the previous coat to dry and move on to the next. Use a mixer to make the solution. It is better to do this with special tools, and not with your hands, so that there are no lumps. Sift dry components, if possible, so that elements larger than 2 mm are not caught.

If you make the final layer correctly, you can glue wallpaper or paint walls directly on it.

To work, you need a wide spatula:

  1. Apply the mortar to a wide spatula;
  2. Press it well against the wall and move up the wall from the floor in sweeping movements. You kind of rub the putty into the wall.
  3. Some experts recommend making movements in an arc. Here, the choice is yours.
  4. Remember that each subsequent layer should cover the previous one by a couple of millimeters.

We are waiting for everything to grab and carry out the grout.

Features of the restoration of uneven plaster

If you decide not to knock everything down, but to align, then be sure to stock up on fishing line (threads), which we will pull horizontally and vertical directions at a distance of 40 to 50 cm.

The most laborious process will be the process of pulling the line. We need to form an "imaginary" surface that we will fit all walls to.

Most often, the surface is leveled with cement mortars, a reinforcing mesh is also required.

We fix the mesh, throw in a little more mortar than necessary, then iron the plaster. Spread everything well with a spatula or rule.

Take your time, but do not drag out the whole process, so that the solution does not freeze. Allocate about 1-1.5 hours for one batch.

We wait for drying before starting grouting.

When the top layer dries out, you can spray water on it and start work. Remember that an acrylic or polymer film makes the surface more durable and allows it to deform.

The finishing layer must not exceed 3 mm.

Gypsum plaster

Gypsum mix is ​​in great demand and most often it is taken to carry out the finishing plaster.

They are white in color and therefore easy to repaint, or even very thin wallpapers.

Before preparing the solution, read the instructions. Some conditions must be met:

  1. We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick The room temperature should not be less than 5 degrees and should not exceed 25 degrees.
  2. Store the mixture only in a dry place, the plaster absorbs moisture very quickly and deteriorates.
  3. Do not cook large quantities at once, as the material hardens quickly.

Gypsum can be used both in the main part of the putty and as a finish. I work with them in the same way as with other mixtures. We collect on a wide spatula and rub in. Make sure the base is damp. If the gypsum has already frozen, then it is strictly forbidden to dilute it with water, it will lose all its properties.

To make the plaster more durable and smoother, do not forget to grout with a special tool.

This can be a grater. Rub counterclockwise and in a circular motion. Do not apply strong pressure to avoid damaging the finished surface.

You can also use metal or rubber pads.

In this case, move only vertically or horizontally. Start from floor to ceiling.

Facade plastering

Facade plastering helps to protect the house from environmental influences. Synthetic components can be found in the composition of such plasters; they significantly improve the characteristics of the material.

The pluses include :

  1. We apply plaster to internal and external walls - Overview and Application 1 and 2 mm thick Does not ignite, therefore it is an excellent fire barrier.

  2. Service life up to 20 years.
  3. Low cost of materials.
  4. With a sufficiently thick layer, it does not let in extraneous noises and sounds.
  5. Can be used on a variety of substrates, from brick and concrete to wood and foam.
  6. Does not create additional load, as it is lightweight.

  7. Does not respond to temperature changes.

Preparing the surface of the house for plastering:

  1. We remove all canopies that will interfere with the work.
  2. Remove all fasteners and remove stains and dirt.
  3. All cracks and gouges must be repaired.
  4. We go over the entire surface with a primer.

  5. We carry out the installation of insulation.

For insulation, you can use polystyrene, polystyrene foam or mineral wool. The process itself looks like this:

  1. Mount the profile. This will be the support.
  2. We fasten the guides horizontally.

    So the whole structure will be sturdy and reliable.

  3. Starting from the bottom corner, place the insulation.You can use glue or special fasteners. Remember that the joints do not have to overlap. We put the insulation with brickwork.

  4. We seal all joints with sealant.
  5. Put a net on top of the insulation.
  6. We carry out the putty. Remember if your mesh is made of fiberglass but is placed on plaster and sunk.

After everything is dry, decorative plaster can be applied.

Technology for applying decorative plaster

Do not forget to follow the instructions when preparing the solution, otherwise problems with application cannot be avoided. The composition includes binders (cement, resin, polyvinyl acetate, etc.), as well as various fillers (granite, quartz, sand, etc.). If larger fillers are used, then the plaster is intended for external surfaces, smaller fractions indicate that it can be used indoors.

In order for the mixture to be of one color or another, a special pigment can be added. Pigments can be synthetic or natural (coal, malachite, etc.). The latter will cost much more than synthetic ones.

The following mixtures are most often purchased:

  • - Venetian composition,
  • - mixtures that have a click effect,
  • - bark beetle,
  • - a mixture similar to rain or rock,
  • - compositions with marble chips,
  • - compositions resembling a stone.

You can buy a ready-made decorative putty or a mixture for preparation. Ready-made mixtures are more convenient to use, you do not need to waste time and worry that you will not get a high-quality solution.

Decorative mixtures for the facade are:

  1. Mineral - the easiest option, since its composition is cement and sand. The mixture is durable and easy to work with. Such a "fur coat" was often found in homes.

    The solution needs to be rolled over, but not smoothed.

  2. Silicate - liquid glass is taken as a basis. It is a very durable material that does not retain dirt. It is very difficult to do it yourself, so it is easier to buy a ready-made mixture.
  3. Acrylic - it contains synthetic resin.

    You can pick up options in different colors. Over time, the pigment may fade, but the surface can be painted again.

  4. Silicone - has the highest cost, and also requires skills in work. Has a long service life.

There are three most popular options for applying the decorative composition:

  1. Spray.

  2. Spraying.
  3. Tensioning.

The first option is the simplest. We immerse a brush, broom or other similar tools into the composition, with the other hand we take a stick. We bring the broom to the wall, and knock on it with a stick.

Splashes of different size and location are flying onto the wall. We wait for some time until everything hardens and repeat the procedure. You can overlay as many layers as you like. With the Italian method, there is no need to wait for one coat to dry before applying the next.

IMPORTANT: apply multi-colored mixtures: blue, green, red, etc.

You will get a bright original facade.

For spraying, you need to buy or rent special equipment. With the help of the installation, continuous spraying occurs. Start work from the top of the wall. Using this setting, you can paint the house in one color, and the details in another.

Do not apply more than 3 mm layer.

Pulling is considered a simple method. For work, you need a grater or trowel. Move from the bottom up. Maintain an angle between the tool and the wall up to 60 degrees.

On top, you can shape the pattern you want.

Plastering with a trowel and trowel

Using a trowel or trowel, you can easily create imitation stone, Venetian plaster or other options. It is easy to do this:

  1. The first option - apply a small amount of mortar on a spatula (trowel) and cover the surface with small strokes. Overlap the strokes. You can do all the strokes in one direction, or in different directions.

    You can arrange them in an arched manner. It all depends on your imagination.

  2. The second option - we also put the solution on the trowel. We apply it to the surface, lightly press and remove. You can do it more quickly: stuck - unstuck.

    Also, if desired, turn in different directions and directions.

Application of plaster with a roller

You can take paint rollers, or purchase special ones made of rubber. They can also have a different pattern. You can create a roller attachment yourself, just wrap a rag, rope or bag around it.

Let's start :

  1. Make a 3 mm layer of plaster.

  2. We pass the roller along the surface, thereby a pattern appears.

To create a "fur coat" effect, use a roller with fur. We dip it into the solution and hold it along the wall.

FOR INFORMATION: Excess mortar can be removed with a spatula. Roller work should not have long breaks, since the solution dries quickly, and the joints will be very noticeable.

Working with a brush

For working with a brush, it is best to take a ready-made mixture. The advantages of this type of work include:

  1. An economical option, since a very thin layer can be applied using a brush.
  2. The working speed is high and texture appears on the wall immediately.
  3. No special skills or knowledge required.

If there is sand or marble chips in the solution, then the surface is rough.

Plastering with a sponge

In this option, foam rubber residues, dishwashing sponges, various bags and even pieces of fabric are suitable.

Create an even layer of plaster, then dip a sponge into the mortar and brush the wall. So you can cover not only the entire wall as a whole, but also, for example, select individual areas. We are waiting for drying and rubbing the edges so that they are not very sharp.

Plaster by machine application

The advantages of this option:

  1. High working speed.

  2. Strong and reliable connection.
  3. Less material is consumed than with hand.

Decorating options are not as diverse as when working with your hands, but it is a very convenient option for leveling the facade. These can be:

  1. Machine station . The solution is made in the apparatus and is sprayed onto the wall.

  2. Pneumatic pistol . The solution is poured into a funnel and sprayed onto the surface.
  3. Pneumatic bucket . Very similar to the previous version, but with 4 nozzles.
