Work on plastering facades implies applying a cement layer or cement-known coating on the outer walls. This is done with a protective and decorative goal. Before starting work, we need to think about the design. The fact is that the facade of the building must be harmonized with its common appearance.

You can guide the work with your taste. After all, no strict requirements for this account exist. Everything is limited only by your financial capabilities and personal preferences. In addition, it is worth considering what your home should harmonize and with neighboring houses.

When carrying out facing works, almost the same tool is used as for internal plaster. Techniques for these works are also similar.

Materials

Today there are quite a lot of materials for these works, but all of them can be divided into three groups:

1. Colored lime-sandy.
2. Stone.
3. Terrazite.

For decoration of light concrete, brick walls, walls of tuff, porous ceramic blocks and shells are used colored lime-sand plaster mixes. These coatings are applied to soils usually with the addition of cement.

For finishing of capital buildings, terrazite plasters are used.

Surfaces made of brick, heavy concrete and materials with a brand not lower than 100 can be decorated with stone plaster. Before applying the walls need to be treated with cement primer. This mixture is an appearance imitates natural facing materials. For less durable surfaces, it is impossible to use this mixture.

Characteristics of facade plaster

Modern plasters must have the following important characteristics:

1. Resistance to temperature drops is of great importance for areas where there is a big difference in seasonal temperatures.
2. Moisture resistance - protection of the building from high humidity and precipitation.
3. Parry permeability is a property allows you to produce outside steam and thereby breathes the building.
4. Soundproofing and thermal insulation - thanks to these properties, a more comfortable microclimate is created in the house.
5. Strength - countering mechanical impacts.
6. A variety of colors and textures - allows you to create surfaces of different colors and textures.
7. The ease of applying a solution is a property helps to put the facades to be plastered with their own hands, while saving on expensive services.

Types of facade plaster

Any plaster is a complex of binders and additives that affect the properties of the finished coating, applying technology and appearance.

Mineral Plaster

Sold usually in the form of a dry mixture. To mix it is very important to observe the proportions indicated on the packaging by the manufacturer.

Advantages

1. High strength that increases time.
2. To increase moisture resistance, this material is enriched with special additives.

disadvantages

Small selection of color scheme.

Acrylic plaster

This material is sold in the form of a finished mixture. To use it you only need to mix well. It is well suited as a material for decorative plastering of facades at home. Binding substances are various resins. To increase resistance to temperature and high humidity drops, special additives are introduced into the composition. This plaster can protect buildings from various microorganisms, for example, from mold. The most popular view of such a material is the plaster of the core.

Plaster koroed

This plaster may be in its composition various polymer fillers, which is why the technology of plastering facades by material from different manufacturers may differ. Therefore, the unified method of applying a cores does not exist - therefore, always before starting work, you need to carefully read the instructions. All brands of this plaster in its composition have cement and marble crumb graininess 0.1-3.5 millimeters. The larger the grain, the more consumption of the material. On the packaging of the cores, the average consumption is always indicated. This can help to calculate the required amount of material. Most of the stamps of this plaster are white, but sometimes it is tinted with special paints.

Advantages:

1. Resistance to atmospheric phenomena.
2. Frost resistance.
3. High strength.
4. The coating can be washed.
5. It is resistant to the effects of direct sunlight.
6. Stability to alkalis, acids and industrial gases.
7. Even with high humidity, the surface for a long time will maintain its attractive appearance.

Silicone plaster

This is a high-quality and universal finishing material. The basis of this plaster is the polymer compounds, which allows it to protect the building from any impacts and for a long time to maintain it in its original form. This material prevents the development of microorganisms, reckles the dirt well and is distinguished by high vapor permeability. You can find silicone plaster almost any shade, but it has a high cost. As a result, we get high-quality plastered facades. The price of work is the highest.

Silicate plaster

This material is made on the basis of liquid glass. This plaster is recommended to use for finishing buildings from porous materials.

Advantages:

1. High vapor permeability.
2. Good plasticity.
3. Easily applied.
4. Perfectly pushes dirt.

When choosing facade plaster, you need to consider the requirements that are subject to appearance and surface properties. On the package, you can often read the characteristics and recommendations on the use of this plaster.

Features of the building solution

The composition of the construction mixture:

1. Sand - the main mass of the mixture.
2. Cement - for a ligament of individual fractions.
3. Pure water.

If a high-quality mixture, it can well be adopted with any texture of masonry. The solution can be any density. To do this, you only need to change the proportions of cement and sand. Instead of cement, you can also add lime.

A solution from cement is suitable for light bricks and foam blocks, and it is better to choose a cement-sandy solution for walls of dense heavy brick.

After mixing cement with water, a chemical reaction begins, which is called hydration. It is due to this reaction the cement freezes. Moreover, the longer the cement dries, the more stronger it. Therefore, if plaster works are carried out in the summer, then it is necessary to abundantly moisturize the frozen cement by watering the facade from the hose. You can moisturize yet, biting the facade with a wet rag.

When carrying out plastering, the following materials are applied:

1. Cement.
2. Sand.
3. Dry mixture solution.

Often, cement is used in the work, which is called Portland cement. This material consists of limestone, clay and chalk. With the help of additives or adjustment of manufacturing technology, different types of cement are obtained.

So, you can get, for example, the following types of material:

1. Portland cement wide destination. This is an ordinary light gray cement. It is quite cheap. To get the desired mortar for work, it is necessary to mix it with aggregates. It is usually supplied in bags of 25 or 50 kilograms.
2. White portland cement. This type of cement is better and somewhat more expensive than the usual one. It is used to prepare a solution for boot and brick masonry, as well as for concrete and cement plaster. It is easily mixed with construction dyes.
3. Quick-frustrating cement. This material is most suitable where fast drying is needed, without loss of quality. It is only 30 minutes enough to grasp it. At the same time, it is distinguished by water resistance and does not give a shrinkage.
4. Masonry cement. It is used for external trim, as well as for boot and brick masonry.

For plastering, sand is still used. This is the smallest aggregate. It happens a few species that differ in grain size and shape. This material may be:

• Coarse-grained.
• Fine-grained.
• Graduated (fractions of various sizes).

Before using sand in plastering, it is necessary to rinse well and remove foreign bodies from it.

Works on the facade finishing are noticeably easier if applied solutions from ready-made dry mixtures. Today you can buy in any construction store. They are usually sold in bags of different sizes. To prepare a solution from such blends, it suffices to connect the contents of bags with clean water into the proportions indicated on the package. Just need to remember that it is impossible to store the packaging open for a long time. In addition, before breeding a mixture with water, you must first mix it thoroughly. In order for the surface color in the end, it turned out uniform, and the texture is uniform, it is necessary to strictly follow the instructions.

How to knead the solution

1. One prepared portion of the solution can be used for about one hour. Therefore, it is necessary to cook in that quantity that will be spent in one hour. An hour later, the solution will already be dried and will become not suitable for use. Before you start, you need to check the tool - it should not be left of the old material and it must be clean. Sand buckets and cement Take different things to not mix and not spoil the material.
2. To knead the solution, first measure the desired number of sand buckets and pour them on the mortar board.
3. After that, with the help of a second bucket, you need to measure the required amount of cement and pour a lot next to the board with a bunch of sand.
4. Then these materials must be mixed up to complete inhomogeneity. To do this, shift in turn of it from one heap to another.
5. In the center of the heaps should be deepened and pour water into it.
6. Next, with the help of shovels you need to be added to the water dry mixture lying nearby.
7. Before starting work, check the density of the prepared solution. To do this, you can spend a mixture with a shovel groove. If at the same time the edges are supreme, then the solution is too dry, if the edges float, then it is too wet. If there is no other, then you need to remember the amount of water in order to know how much to take it into the following portions.

Sewing concrete mixer

Even a small concrete mixer can simplify and speed up the preparation of the mixture. Today it is not necessary to buy it at all. Especially if it is planned to use only once. Some stores and construction firms present services for leaseing such tools. Before mixing, you must definitely put the board under the drum so that the incident material poured on it.

The process of booting the concrete mixer consists of the following steps:

1. Download ½ Sand Portions.
2. Upload ½ portions of cement.
3. Mix dry components by turning on the concrete mixer.
4. Stop stirring, add ½ of the water and re-enable the mixing.
5. Adding parts cement, sand and water.
6. After each kneading drum mixers must be washed. To do this, after the work start up to a powerful jet from a hose.

Preparatory work

When plastering facade must be:

1. Strictly observe the technology of preparation of the solution.
2. Competently split into zahvatki.
3. Use the same ingredients.
4. To have on hand all the necessary tools and be careful.
5. it is recommended to practice before the main work on something that is not essential in the selection of the same color mixture.
6. It is important that the temperature of the treated surface was not less than 5 and not more than 30 degrees. When this is considered an optimal value of humidity - 70%.
7. In addition, it is not necessary to plaster during inclement weather (rain, snow), or immediately after it. More is not necessary to be allowed to the surface in direct sunlight.

methods of application

There are only two ways of applying the solution:

1. Manual - with the help of special tools.
2. Mechanical - with the help of machines and mechanisms.

For large volumes of work is better to use a mechanical method.

Preparing walls

Before you apply a decorative plaster on the wall, you must:

1. Align wall rough plaster.
2. After the drying process the layer of plaster.
3. Cover the primer.
4. Make marks on the zahvatki.

To hide the joints from the compounds surface layers must be divided into sections, which are called zahvatki. Thus their edges must pass through the inner corners of the edges of any projecting elements. To achieve even and smooth edges zahvatok, when applied to skim the layer you need to put beacons and rules.

The process of plastering

There are two basic ways of drawing smooth plaster:

1. Beacons. Beacons are thin rack with a protruding rib, which are mounted on the wall in a vertical position. The distance between them - 0.5 - 1 meter. All edges must be checked with a spirit level. For applying the solution using a trowel or float. Align it can be using a wide spatula.
2. With the help of rules. Rule - a special building tool that is used in vykladyvanii leveling material in large volumes. This tool is useful when working on wide walls.

The solution may be applied to the wall of the following ways:

1. Trowel.
2. Small spatula.
3. Wide spatula.

Plastering the walls of gas and foam concrete

1. Suitable stucco thickness for such walls - 5-10 millimeters. It is important that the outer layer was in two glad thinner than the inner. Outside there will be enough thickness of 5-10 millimeters, and inside - 10-20 millimeters.
2. The plaster is better kept on the rifle surface from cellular concrete. Alloy blocks should be pre-sand.
3. For foam concrete, the most suitable mixtures with a large adhesion coefficient. It can also be used to shock the facades on foam.
4. To increase adhesion, a reinforced grid is usually used.
5. For coloring plastered facades from foam concrete, the facade hooks with the addition of silicate or silicone are best suited.

Plastering walls from concrete

Before starting work, it should eliminate various small defects on the surface with the help of draft plaster or repair putty. Before applying a decorative coating, the surface must be rebounded with a roller or with a collapse.

Three separate layers are applied to concrete walls, which are called:

1. Sprinkle - a semi-liquid layer with a thickness of 3-5 millimeters.
2. Soil is a thicker 7-10 millimeters thick layer.
3. Cover - decorative thick layer 4-7 millimeters thick.

Walking of brick walls

If it is necessary to work on a brick surface, then plastering the facade on the grid is carried out. There are notches or put under the bottom of the stucco, a small metal mesh. After that, the same three layers are applied: spray, primer and covers. According to the same technology, plastering facades for insulation is performed.
