Plaster walls with cement mortar

Plaster is a building process that allows you to align the wall and provide thermal insulation of the house. Also, it hides the wires and increases the level of sound insulation.

There are many solutions that are used to plaster walls. But the most popular is cement. It has many useful properties like good resistance to high moisture level. Also worth noting is the strength.

Prepare the wall from different materials to plaster ↑

The preparatory phase is extremely important if you want to achieve smooth wall surfaces without flaws. Before you apply the plaster you need to determine what material is made the surface. This will depend on the actions.

Working with brick ↑

Despite the variety of modern materials to create walls in most cases the use of brick. This is not surprising, as the material has many positive qualities, which explains its high popularity.

If you can see a wall with ordinary bricks, then before you apply the grout to plaster with your hands, you need to evaluate the degree of humidity of the surface. In the case of new development no preparatory actions.

Dry stone is found in buildings that already long time are in operation. In this case, before you apply the grout to plaster it is necessary to spray the surface with water. If you do not, then the makeup will be sliding off the walls.

If the wall construction used a facing brick, the algorithm of preparation for plaster cement mortar will be more difficult. First and foremost, you need to attend to the installation of the sheathing.

There are many technologies installation of high-quality sheathing the walls before you start making the plaster with cement mortar. One of the most reliable and fast is considered to be the following:

1. Beat in the mortar between the bricks nails.
2. Screw nails aluminum wire.
3. Check the tension.

Sometimes you have to work with small sections of the walls. In this case we can apply the trick with tile adhesive. Take a notched trowel and use it to apply glue in a thin layer.

There is another important stage in the preparation of brick walls for plaster cement mortar. Is priming. Only after it you will be able to do the main work with the predictable result.

Preparation of walls of other materials ↑

Working with concrete blocks is quite difficult, since the grout will just slide down. Fortunately, the above description of the two methods will allow you to provide fixation of plaster with glue or crates.

If you need to apply plaster onto a wall from cinder blocks don’t forget before starting work, thoroughly wet the surface. This will ensure good and secure fit.

In fact, there are a number of materials that require processing before applying the plaster by cement mortar:

1. Sawn limestone. Training algorithm is the same as the cinder blocks.
2. A wooden wall. To plaster with cement mortar treat the surface with primer and install a special grid.
3. Drywall. Enough processing primer.
4. A non-uniform coating. Sometimes you have to plaster with cement mortar of walls of different materials. In them, the differences can reach 20 centimeters. Therefore, it must be aligned before you do anything. To align the ideal cement mortar. But before you start pre-processing — programsuite the wall and install a special grid.
5. A plaster wall. Often under the influence of time the old plaster is in disrepair and you have to attend to on a new coat. But in order to do that, you need to remove the old layer. This procedure is most convenient to carry out with the punch. In a pinch you can use a hammer and a chisel.

If you properly prepare the walls before the plaster, the cement mortar will fall on them evenly and last long. The surface has just made a brick house does not require any preparatory treatment.

Apply the solution ↑

Reinforcing mesh ↑

In order to apply the grout on the walls better suited to a special mesh. It will increase the strength and elasticity of the plaster, and this, in turn, will prolong its lifetime.

Ordinarily when you use a grid with cells of 20 x 20 mm., It is ideal to lock the grout. But to achieve really good result, you need to care about the anti-corrosion coating.

For the installation generally use the dowels. They need to be fun from each other at a distance of about 35 centimeters. One of the most proper arrangements considered to be chess. It allows you to save a lot of time. After dowels are installed, you must cut the mesh the right size.

The correct way is to set the grid from the bottom up. The elasticity of the product allows for easy on wear on the dowels and fix it. While on top you need to wind the wire. More precisely, it is necessary to lend to each dowel. As a result, you should get the letter Z.

When matching multiple pieces of mesh need to unleash on each other. This will increase the strength of the plaster. In addition, it will increase the resistance of cement mortar mechanical damage.

Beacons ↑

Beacons is an important element when applying the cement mortar, which allows you to make the plaster flat and smooth. Typically, the beacons use nails.

There are several methods of creating lighthouses. For example, you can make key points with cement mixture. Alternatively often use tile adhesive or the putty.

On point sets the beacon. To install it precisely — it is necessary to use a level. To prevent bending you can use this rule. It is necessary to attach the level during the application of the beacons.

Now we need the vertical lines to drill holes. They hammered cruising areas. They later screwed lighthouse the profile. This task is ideally suited 25 mm screws.

Holes from baldness to cruising areas are subsequently filled by cement mortar. This will avoid deflection under the weight of rules. This method allows qualitatively to perform the work, even with large bumps.

Application ↑

In order to apply the cement mixture on your walls you will need a number of tools:

• plaster bucket,
• spatula,
• trowel,
• rule,
• Kel,
• grater.

With their help, you will be able to apply the grout, thereby making the walls good insulation and beautiful appearance.

Before you start to apply the mixture make a coating. If this is not possible — just moisten the wall. Apply cement composition is necessary until they are completely dry.

For spraying of the composition is used in a ladle or a trowel. After that, by the rules and two lighthouses is the alignment. Also, this procedure allows you to evenly stretch the substance on the surface.

When the wall is dry grout. For this you can use the same solution, but in a much more liquid form. Application is made using the float. You need to grind before the formation of the smooth surface. How is the plastering of walls with cement mortar with your hands, you can see in the video below.

In order to increase the operation life of the plaster, you can use the Etchant. This procedure increases the resistance of the cement layer, mechanical damage and allows to avoid the formation of mildew on the surface.

For treatment of walls uses a special solution with a neutralizing acid. It is necessary to use personal protection to avoid chemical burns. The complete kit consists of gloves, gown, respirator and goggles. Special shoes will not be superfluous.

Attention! All of the Etchant should be done in a well ventilated area.

The results ↑

Plaster walls with cement mortar can insulate the house with his own hands. The wall surface becomes suitable for painting or wallpapering. But to get it you need to carry out preparatory work. It is particularly important to moisten the surface before applying.
