Types of plaster
Today, many varieties of mixtures are used for plastering facades. These are textured solutions that differ in a number of characteristics. The most popular manufacturers of dry mixes for such finishing are the KNAUF and Ceresit companies. Facade plaster may contain various fillers.
To set the desired texture for the finish, the composition of the solution includes components of various grain sizes. It can be marble chips, quartz sand, colored granules, glass dust, wood fibers, etc.
To color the mixture, dyes are added to it. In this case, you can achieve almost any shade. Tinting is carried out in a trade organization using special equipment. This allows, if necessary, to set the base to exactly the same shade, if you have to buy a dry mix. The heterogeneous structure of the solution allows you to hide the unevenness of the base.
Finishing methods
Coating the facade of the house can be mechanicalway or manually. In the first option, you will have to purchase special equipment. Companies such as KNAUF, Ceresit, whose facade plaster production is very popular today, are developing a special line of products that can be applied mechanically to the base. This approach is preferred by professionals who do a significant amount of finishing work.
For craftsmen who wish to apply the solution to the facade of their home, it is better to do it manually. This way you can save on the purchase of special equipment. In this case, you will need to purchase only ordinary tools. To create a certain type of texture, you also need to buy curly spatulas.
In the process of applying the solution in any way, you should strictly follow the manufacturer's recommendations. Only in this case it will be possible to create a strong, beautiful protective layer.
Working technology
Finishing work is carried out according to a certain technology. By correctly performing each step, you can achieve a good result, even without experience in carrying out such actions.
Facade plaster for outdoor work, the price of which will be affordable for almost every owner of a house or cottage, is designed to finish the base of various materials. It can be brick, foam concrete, or other types of building materials. The most optimal and inexpensive way of finishing is the use of beacons.
The work is done in several stages. First you need to prepare the base, then the beacons are installed. Only after that you can start plastering the facade. This method is suitable for manual application of the solution. It is important to adhere to the proportions when kneading the dry mix, as well as the manufacturer's recommendations regarding its drying time.
Preparing the base
Plastering of brick facades or made of any other materials must begin with the preparation of the base. If this step is skipped or not performed well enough, the result will not be high enough.
First you need to remove the old finish. It is beaten with a small hammer or a wooden block. Where the sound is deaf, the old finish is knocked out with a chisel and hammer. In some cases, you will need to use a hammer drill. Also removes dirt, oil stains and dust.
It is desirable to reduce as much as possible the number of irregularities, bumps on the base of the walls. If this is not done, you will have to apply the plaster in a thick layer. Material consumption will increase significantly. Therefore, it is better to properly prepare the surface of the walls than to spend the family budget on the purchase of additional dry mix.
Recommendations for ground preparation
Brick base requires, in some cases, jointing. This procedure allows you to increase the adhesion of the solution to the base. The plaster will hold tight, and the life of the coating will increase. Some builders in the construction of brickthe walls of the houses leave the facade with empty seams. This allows you to prepare the base for finishing faster.
For foam blocks, the jointing is not done. This also applies to walls made of reinforced concrete slabs of "rough" masonry, in which the surface is smooth. A mesh for plastering facades is immediately stuffed onto such varieties of materials. A deep penetration primer must first be applied. It will enhance the adhesion of the mortar to the base.
When choosing a primer, you should give preference to trusted manufacturers. It is also necessary to adhere to the correct concentration of the solution. In this case, the film will be strong.
Lighthouses
The technology of facade plastering involves the use of beacons. These are metal guides. They are installed on the base to indicate the level of plaster application. The rules, leveling the layer, slide their nose along the tops of the lighthouses.
It is believed that the use of this method of finishing allows even a non-professional to make a perfectly smooth surface. However, the master needs to familiarize himself with the technology for installing beacons on a plane.
It is necessary to determine the verticality of the wall with a plumb line. Deviations from the level must be determined before installing the guides. If the top of the walls is inclined in depth, this indicator must be taken into account. Beacons are customized to a certain size. The excess height of the guides must be cut off.
Installation of beacons
Facade decoration with plaster is made after the installation of beacons. From the corner at a distance of 20 cm applyspot solution. Their diameter should be about 5-15 cm. The height depends on the intended layer of plastering. If the rule is 2 m long, beacons can be installed at a distance of 1.7 m from each other. If the wall is too large, you need to increase the guides.
Each beacon is installed in the solution and sunk a little into it. The level rule is applied on top of each element. If necessary, the position of the beacon is adjusted to achieve the perfect vertical position of the trim. To avoid deviations, errors, it is recommended to pull the "laces" between the two extreme elements during the alignment of the beacons. After the solution dries, the voids formed under the lighthouse are filled with putty.
Applying the first layer
Plastering of the outer wall takes place in 3 stages. Plastering the facade in a mechanized way allows you to perform all actions faster. However, in this case, be sure to work in a respirator and goggles. Otherwise, the solution may enter the respiratory tract or eyes.
Dry mixture must be diluted to the consistency of liquid sour cream. In this case, the manufacturer's recommendations must be taken into account. Ready-made plaster mixtures are also on sale. Some professional builders recommend adding PVA glue to the solution. It will give extra strength. Putty will lie well on the wall.
The mortar is applied to the wall with a scoop. The mixture must be poured onto the base without pouring it. Roughnesson the top layer are welcome. After surface treatment, the solution should dry.
Main layer
At the next stage, the main plastering of the facade is performed. To do this, you need to prepare a solution. It should be the consistency of thick sour cream. It is thrown on the surface between two lighthouses. Please note that the thickness of all layers of plaster should not exceed 5 cm.
The narrow side is necessary to press the rule to the lighthouses. The tool is moved from side to side. The edges of the rule should not fly off the tops of the guides. The movement is made in an upward direction. The excess is cut off. This results in a perfectly smooth surface.
If during the leveling process it turned out that the solution is not enough, it should be added. The mixture is poured into the hole formed. Then again draw the rule over the surface.
Grout
Plastering of the facade involves the final stage. The surface needs to be sanded. This procedure is performed after the cement finish coat dries. For this, special graters are used. They can be made of foam or wood.
If a putty is used that is not based on cement, the manufacturer's recommendations should be followed. They must be indicated on the packaging.
Grouting allows you to smooth out small irregularities, close up sinks after applying the rule. The grout is performed in a spiral. Circular movements begin with wide movements,gradually moving the tool towards the center. A tubercle in the center is stretched from a large circle. With the opposite action, it is completely leveled.
Having considered how the facade is plastered, everyone will be able to perform the procedure well. In this case, the surface will be perfectly flat. Following the recommendations of professional repairmen and builders is a guarantee of a good end result.
